Lawns

A lawn is defined as a living green carpet of spreading turf, which is a product of intensive husbandry and management. Lawns are used to create pleasant views for homes as they link the house to the garden. To produce a good lawn you are required to;

1. Eradicate species that are not grass or the wrong grass

2. Requires application of fertilizers and irrigation

3. Frequent mowing to control strong growth of the grass.

The resultant effect of the aforementioned activities is a stripped green carpet. Having a great lawn is public expectation. Only one type of grass should be grown.

Establishment of lawns

The following are considerations for establishment of lawn

1. Grass species should be suitable to produce a good lawn in the local climatic regime.

2. The method of propagation- lawns can be established from seed or vegetative material; Seed is more agronomic

3. During actual planting of lawns, the land is treated just like agricultural land; this means all activities associated with land preparation for good production are done. This includes plowing, harrowing and application of manure or fertilizer, however land preparation of the seed bed may require grading while removing foreign objects like stones.

4. Never try to bury objects in a lawn area. Ideally top soil should be removed. Remove as shallow as 3 cm and deep as 15 cm; scoop it and pile it on the side or along the paths, establish a gradient.

5. In every 3 to 5 meters, a drop of 6-10 cm should be created away from walks and buildings, sometimes from plants like trees to aid in drainage of water from objects.

6. The center of the lawn should be slightly raised. Fill back the top soil ensure that paths roads are 3-5 cm higher than lawn in general level. This also helps in preventing water logging on the paths. Secondly top soil; helps in smothering the area thus helps in avoiding small depressions or low spots which become a source of drainage problems.

A lawn is expected to be fairly flat. Where this is the case, during land preparation consider a heavy duty rotary cultivator. Afterwards you can do seeding, making sure you have fine seedbed. Cover grass seeds with 0.5 cm of very fine soil by raking the soil with dry branches.

On certain occasions, the land may require grading which is a process of leveling uneven land using machinery. During grading, the original land may be altered depending on the owners’ capability. During certain instances, large trees may be encountered that need to be preserved.

Two approaches have been instituted; when grading involves removing of soil and you encounter a large tree; carefully remove soil from the tree area, leaving a slope from the tree that acts as a mound around the tree covering the main roots.

If grading involves raising the level of the slope; and you encounter a tree use the well. Construct a well around the tree with loose stones. Fill the area up to the walls leaving a depression. If you are in a high rainfall area use aggregate materials to increase drainage.

Steep slopes present great challenges in establishing a lawn on them because they dry fast and the danger of surface run off. At times machinery is not able to move on the surface.

If your land has steep slopes, think of retaining a series walls. Do some cutting and filing to form terraces. If this is being done by machine, there might be some compaction and you may require sub-soiling to enhance drainage.

LANDSCAPING YOUR HOME: DO IT YOURSELF

All of us have the desire to live in a beautiful and clean environment. This desire resulted in creative horticulturists gradually developing concepts of landscaping with the purpose of achieving beauty in the living environment.

In the past, people were satisfied to live in a concrete or stone house that formed a part of the urban concrete jungle that was almost devoid of green vegetation. However things are changing because people are currently aware of the relationship of the environment to their satisfaction, health and well being.

I am sure for a long time; you may have been thinking to landscape your backyard or any space surrounding around your home so as to increase its visual appeal, or to make a statement to visitors in your home.

Most of us think of having an intricate or complicated flower garden or lawn or patio surrounded with hedges consisting of different beautiful plants. Unfortunately that’s not the way to achieve a great landscape for your home. You need a carefully thought out design of how various elements of the design are going to interact together once they are interpreted on the actual land.

QUALITIES OF A GOOD LANDSCAPE DESIGN

Every landscape has elements; consisting of plants, passages, footpaths or just open places. Non plant elements include surfaced roads, pavements, buildings, fences, terraces, mountains, water pools and small lakes; thus a good design shows the harmonious interaction of the aforesaid elements.

Consult professionals who will draw a design that can be easily interpreted and transferred to the ground. Simplicity is the key; a design that posses this quality avoids the overuse or overtreatment of any element in the landscape. Elements should be sparingly used except on a few occasions like grass in a field.

Secondly a good design creates emphasis to certain elements of a landscape, say; a building, pond, door, wall, road or a path. These elements are brought into focus, by using the distinctiveness of diverse plants for example color, height, and shape of leaves, trunk or its form.

Using this principle, a chosen element in the landscape is made the center of attention; while allowing the separate parts of the design to be attracted together. Thirdly, unity must be put into consideration. It refers to the arrangement that pulls all elements of the design to one symphony; so that elements appear to belong to one whole unit.

Unity must exist in a design. It is visual; it is the eyes that have the perception. Unity is achieved where plants show a good relationship in terms of; form, color and texture and through uniformity. Monotony can result, where uniformity has been overemphasized; an unacceptable state.

Fourthly balance in a design is an aspect that implies stability by establishing a pleasant visual weight distribution. Natural balance is applied; which can be, either symmetrical or asymmetrical.

Finally a good design takes proportion into consideration. Proportion refers to the aesthetic relationship or restfulness of the desired size relationship of one part of design to another and to the whole. This is illustrated where a storey building is in proportion with upright growing trees. This can contrast with a single storey house in proportion with a spreading tree. A small patio will be un-proportional with a large lawn.

A large terrace will be in proportion with a small lawn. To make objects or elements of equal size will not be good to view; rather it is not a matter of equality but should be complimentary.

Principle of variety is an aspect that prevents monotony. Variety adds dimension to the design which is reflected with changes that occur at different times of the year.

Harmony and rhythm refers to unity and completeness of design. This quality is difficult to achieve, but; it reflects completeness and shows the pleasing relationship of sizes and shapes. Without harmony, separate components will lose their identity of belonging to the whole.

To achieve rhythm, the same groups of plants are arranged at the same interval (space) this gives a sense of movement and establishes a visual line for eye movement.

On the other hand, scale shows the visual relationships of the objects in the design with respect to size. Establish a pleasing relationship with things in the design; especially those that appear jointed.

Plants especially trees have been used to bring human experience linked to inanimate things. Inanimate structures are difficult to link into design; but trees bring life, by making the building be seen between plant materials.

Finally, line should be incorporated into the landscape design, because it is a means that guides the eye and express emotion. It denotes the shape or structure of the design.

AGRO INPUT COMPANIES: ARE THEY DOING ENOUGH IN EDUCATING SMALL SCALE FARMERS IN KENYA? AND THE ROLE OF AGRO DEALERS

Agro-input companies are large organizations whose operation involves the manufacture, production, distribution, importation of one or more of the following; hybrid seeds, fertilizers, greenhouses, vegetative planting materials, pesticides, Animal feeds, vaccines, bio-stimulants, acaricides, knapsack sprayers and farm implements.

Are agro-input companies doing enough to promote agricultural production among the small farmers? This is a question of great interest to agricultural policy analysts. Various corporates have initiated efforts to assist farmers, for example Amiran Kenya is equipping farmers with knowledge on greenhouse production.

Sygenta has started an insurance policy in collaboration with insurance companies to minimize losses to farmers, Kenya Seed Company conducts field trials in collaboration with farmers during various times of the year- among others.

First, there is some effort to reach farmers, but more needs to be done. This is so because the amount of investment in farmers’ education is so small, compared to the numbers of farmers and their requirements. The information direly needed by farmers is on the; use of agrochemicals, fertilizers, proper choice of seed varieties, animal husbandry and post harvest technologies.

Secondly, according to Kenya government records, it is estimated; over 80% of Kenya’s population resides in the rural areas. Over 70% of them participate in agriculture as their main economic activity. Majority of these farmers are small scale with farms averaging 0.2-0.3 hectares.

They contribute 75% of agricultural output and 70% of agricultural produce. This means that agro- input companies have a huge customer base to reach, thus the investment they put in is a drop in the ocean. Kenya’s population currently stands at 40 million; meaning that agro-input companies have a potential client base of 15 to 20 million farmers. These companies have barely scratched the surface.

Some years ago a Massai herdsman went to an agro-vet shop to buy an acaricide for controlling ticks. When he reached home, it happened that his brother who is a farmer has bought Di-methoate for spraying his crops. They all placed the chemicals on the same place. Sometime later, the one who was to spray cattle decided to spray his animals.

Since, he did not know how to read and write; furthermore no one was near who could do so. He decided to pick one of them and give it a try anyway! Though he was not very sure which chemical he bought, little did he know of the impending disaster. He sprayed his 15 cattle with the wrong chemical and by end of the day, all his animals were dead!

Such stories abound in several parts of Africa, especially among rural farmers. There have been cases of children drinking agro-chemicals, birds and fish being poisoned, farmers applying excessive fertilizers-only to lose their entire crop, farmers spraying herbicides thinking they are foliar feeds. These cases would not have arisen if the farmers were properly informed.

The panacea for the predicament of small scale farmers has been identified in various researches as; collaboration between the government and private sector with the aim of educating farmers. Without doubt agro input companies have a major role in ensuring food security. They have the responsibility of doing more than selling their products to farmers; through active involvement in innovating, importing and distributing technologies of crop production, pest management and good agricultural practice.

Many of them have not been able to suitable develop programs that address the needs of rural farmers; the greatest need being increasing their knowledge base. Most of them have taken the trodden path of using showground’s, using radios, and normal advertising channels to reach farmers but these methods are proving to be unable to sufficiently reach farmers

In this case we will discuss briefly how Agro-input companies are involved in the dissemination of appropriate technical skills especially to small farmers and whether their efforts are sufficient. There are various categories of agro-input companies all who have a specific mandate thus the need to identify the categories of agro-input companies in Kenya.   

CATEGORIES OF AGRO INPUT COMPANIES

(a) Those who supply products that are geared towards crop production e.g. Sygenta Kenya, Semenis Kenya, Mea fertilizers, National cereal and produce board, Athi river mining company.

(b) Those that supply products that are geared towards animal production e.g. Coopers Kenya, Unga limited.

(c) Those that supply products for both crop and animal production e.g. Twiga chemicals

(d) Those that supply products for crop and animal production, industrial chemicals, irrigation equipment and greenhouses e.g., Amiran Kenya, Hygrotech Kenya, Osho chemicals

The Kenyan agricultural scene is dominated by leading farm input companies in the world like Semenis, Twiga chemicals, Paanar Seed Company, Osho chemicals, Amiran Kenya, Hygro-tech, coopers Kenya, Sygenta, Unga limited and local companies that collaborate with international companies. Unfortunately despite their enormous experience, their impact has been minimal in the country. Because of a myriad of reasons that revolves around the strategies employed by the companies in reaching farmers.

HOW AGRO INPUT COMPANIES REACH SMALL SCALE FARMERS

Knowing how agro- input companies reach the farmers is important because; it will enable us to know the numbers of farmers reached, the information passed is improving their production and whether or not they are effective in the strategies they employ.

The principal strategy used by agro-input companies to reach small scale farmers has been, and will be; having stockists in their distribution chain, known as agro-dealers. They act as an intermediary between the agro- input supplier and the farmer.

ROLE OF AGRO- DEALERS SHOPS IN ENHANCING FARMER’S KNOWLEDGE

Agro-dealers are traders who stock goods of several companies like fertilizers, hybrid seeds, animal vaccines, animal feeds, irrigation pumps and any other agricultural inputs. The popularity of this strategy is indicated by its employment by virtually all the Agro input companies.

This is observed by the variety of goods stocked by the shops from different companies. Secondly Agro-dealers are found in almost all towns in Kenya where farming activities take place. Their countrywide distribution makes them suitable conduits for Agro input companies disposing their products to small scale farmers.

This method makes it possible for the agro-input dealers to reduce their marketing costs. The shop owners simply order the goods and they are delivered to their shops or they visit the factories where these goods are manufactured and pick the goods and bring them to their shops.

The idea behind this approach of selling to agro-dealers as opposed to farmers is; to bring products in proximity to the farmer at minimal expense to Agro-input companies, farmers and to provide agricultural information.

A study conducted in western Kenya in 13 districts by Chianu et al titled “Farm input marketing in Western Kenya: Challenges and Opportunities” is a pointer of the dilemma farmers face in accessing farm inputs and the gap that agro-input companies need to fill.

It was noted that the number of Agro-dealers was increasing at the rate of 16% every year; unfortunately most farmers were not able to receive their services. This indicates that demand is growing and more should be done to sustain it.

However, the Agro-dealers cited high cost of transport as a major problem coupled with low demand and high costs of inputs. Rockefeller foundation is funding programs in three sub-Saharan countries that are aimed at developing the rural agro-input stockists.

The program is meant to encourage agro-dealers to organize themselves into purchasing groups to as to achieve economies of scale in sourcing and transporting fertilizers and other farm inputs. Group members provide joint collateral to guarantee supply by agro-input companies.

Agro input companies should be more proactive in adopting the development of afore said strategy. For instance, they can use the internet to collect information of every agro-vet in Kenya and their contacts.

They can then use this information to develop a system that will encourage the agro-dealers to make orders using the system, payment of goods through mobile money transfers, distributing products specific to the various agricultural zones.

Agro-input companies can stimulate demand through conducting intensive farmer education, encouraging farmers to form groups and support in marketing of their produce. With regard to education, it can be achieved by involving community based organizations and NGOs that have a reach in the grassroots in their marketing plan.

If an agro-input company chooses a specific focus area that produces a crop; say maize, he should encourage the formation of ‘product pools’ through the cooperation of community based organization, farmers groups, and other stakeholders.

These pools will be the collection points of the produce for bulking for potential buyers and ease of marketing. The uptake of input use cannot be enhanced if farmers produce does not find a market.

Secondly, using this strategy will increase the array of products that he can sell to farmers. For example to produce maize you need inputs like seed, fertilizer, herbicides and pesticides and preservatives.

Farmers have in the past been duped by some organizations to plant a particular crop, adopt a certain process to boost their production. After they harvest a bumper crop, the organization disappears leaving farmers with produce; which at times lacks local demand.

This is because the initiating organization lacks the financial ability to buy or market such produce. As an agro- dealer adopts the strategy of helping farmers in marketing; he should focus to empower farmers to be independent of external assistance.

CHARACTERISTICS OF AGRO-DEALERS

A study conducted in Uashin Gishu and Machakos district revealed that 58% of the owners of this business have a college education and only 13% have a post secondary education in an agricultural field.

It was also observed that 44% of these owners managed their business on a full time basis, while 46% on a part time basis and a further 10% did not participate in managing their business at all.

It was also noted that 67% of the owners employed regular workers whose average age was 27 years. Out of the workers only 40% of the workers had a post secondary education.

Uasin gishu was chosen for the because it is a high potential area receiving over 1200mm of rainfall annually, while Machakos is much drier receiving between 750-1200 mm of rainfall. Though the study was conducted in only two districts, It was assumed that the two districts will reveal the nature of agro-dealers since the two districts represented the extreme climatic areas where agriculture is practiced.

The results indicated though owners of agro-dealers have high levels of training, their skills may not maximally benefit farmers since less than half of them are involved in day to day running of the business.

HOW AGRO-DEALERS INFORM FARMERS ON EXISTING AND NEW AGRICULTURAL INPUTS

The Agro-dealers advertise the products of the Agro input companies by hanging posters of various products inside their shops. The posters are obtained from agro- input companies as the stockists purchase their requirements. These posters have the following information; a photograph of the product, its trade name and name of the company that supplies the product, where it is used i.e. on plants or animals and the purpose of the product for example controlling powdery mildew, ticks.

Other details are left out thus a farmer may not know the dosage of the product to use and other details at a glance, unless he first buys the product and reads the information on the label. In my opinion, it is the technical details that matter most to the farmer like: dosage, the suitable stage of plant growth for product use and side effects.

The other way is when the sales person working in the store relays this information to farmers as they purchase various products. This is effective when the salesperson has undergone training in an agricultural institution and is conversant with various challenges facing farmers. Unfortunately, less than 40% of the sales people have this knowledge.

It’s sorry to say most farmers do not have knowledge on suitable agrochemicals for the crops in their farm, how to use them effectively, which diseases or pests controlled by various products.  Most of them are semi-literate; they are not able to know the components of chemical. The way the various agrochemicals are branded also confuses the farmers and the Agro-dealers.

LIMITATIONS OF USING AGRO-DEALERS AS A WAY OF PASSING INFORMATION TO FARMERS

Weak regulations of agro-dealers have resulted to doubts on their ability to deliver. It has been established that, owners of the shops may have knowledge on agriculture; however they employ assistants who lack agricultural knowledge, secondly a small percentage of them run the business full time, therefore farmers are not able to benefit from the knowledge of the owners.

Also, weak regulation of Agro-dealers by the Agro-chemical Society of Kenya, Kenya plant health inspectorate unit and pest control products board, results to counterfeit products being sold to farmers. These institutions are mostly concerned with regulating big industry players but fail to monitor the agro-dealers scattered throughout the country. Furthermore various studies conducted in the country indicate that the institutions are underfunded and can’t be able to fulfill their role effectively.

OTHER WAYS USED BY AGRO-INPUT COMPANIES TO REACH FARMERS

USING SALESMEN

Sales is achieved in 2 ways

Agro-input companies need only to employ salesmen who target the agro-dealers as opposed to the farmers. This sales strategy is used where farmers are; scattered in the countryside thus reaching them is difficult and expensive, or where there is a diversification of crop production such that it would be impractical to address the challenges faced by farmers.

Secondly by targeting farmers directly- this strategy is employed where large numbers of farmers grow the same crop or closely related crops meant for commercial purposes. For example farmers in Kirinyaga district practice horticulture for the exports market. They grow crops like French beans, mange tout and cucumbers among others. Because of the high level of organization of farmers, it is cheaper for salesmen to directly sell to them.

The salesmen are properly trained, most of them have a college education so besides availing products to farmers and they also provide extension services. This proves to be more effective than agro-dealers in dissemination of agricultural technology to farmers compared to agro-dealers.

However the impact of the salesmen is localized in major towns, and market centers surrounding major crop production centers where the salesmen can easily meet their targets.

THROUGH FIELD DAYS IN VARIOUS FARMERS FIELDS

During such sessions, the Agro input companies are able to advise the farmers on suitable seeds for their specific areas, proper agro-chemical use etc. This is a good strategy where Agro input companies can meet the farmers. Unfortunately there is a weak follow-up of the programs hence minimizing the impact.

AGRICULTURAL SHOWS AND CONFERENCES

In this method, the agro-input companies have stands in agricultural shows through which they reach farmers. Various products are displayed and the farmers have an opportunity to ask questions and seek advice. However shows have proved to be ineffective since such they are seasonal, majority of those who attend are city dwellers who are not involved in farming and are losing popularity among the masses. They also organize conferences where various industry players attend to discuss which are aimed at attracting professionals.

ADVERTISING ON THE PRINT AND ELECTRONIC MEDIA

The disadvantage of this is the high costs of advertising hence its minimal use to reach farmers. TV is the most versatile due to its audiovisual properties but the target is limited to those with a source of electricity. Newspapers are not able to reach farmers who are illiterate  

CONCLUSION

Agro-input companies need to intensify their efforts of reaching small farmers. The strategies they employ have been effective in various ways, but have not been able to reach many farmers as required. There is need to think outside the box!

CONTRIBUTION OF SORGHUM TO GRAIN REQUIREMENTS OF KENYA

The Kenya government outlines the challenges facing the agricultural sector in its Vision 2030 blue print and reckons that the sector can play an increasing role in economic development of the country. For example sorghum is said to contribute up to 1 % of food grain crops. It has been noted that over one million hectares of land in semi arid regions is lying idle. This huge acreage is suited to various varieties of sorghum and other dry-land crops. Sorghum can play a leading role in food security if this land is reclaimed and put under proper use.

According to Opole et al, in his research titled, Improving Ratoon Management of Sorghum for Increasing Yields in Western Kenya, There has been on steady decline of the area under sorghum. By the year 1994; 175,000 hectares were covered by sorghum which yielded 108,000 metric tons. This reduced to 123,184 ha in 1999 which yielded 90,000 metric tons. The reduction was attributed to production constraints including competition from maize, reduced farm holdings and pests and diseases. By the year 2006, after amplified promotion of the crop as a solution to beat harsh environmental conditions, the acreage increased to 123,000 hectares.

CLIMATE CONDITIONS, SOIL AND WATER MANAGEMENT FOR SORGHUM

Sorghum is adapted to a wide range of environmental conditions and will produce significant yields under conditions that are unfavorable for most other cereals. Sorghum is particularly adapted to drought. Sorghum also tolerates water logging and can be grown in areas of high rainfall. It is, however, primarily a plant of hot, semi-arid tropical environments with rainfall from 250 mm that are too dry for maize but performs best with more than 900 mm annually.

It is also grown widely in temperate regions and at altitudes of up to 2500 m in the tropics. Sorghum tolerates a wide range of temperatures. Sterility can occur when night temperatures fall below 12-15°C during the flowering period. Sorghum is killed by frost.

Sorghum can be grown successfully on a wide range of soil types. It is well suited to heavy clay soils (vertisols) found commonly in the tropics, where its tolerance of water logging is often required, but is equally suited to light sandy soils. It tolerates a range of soil pH from 5.0-8.5 and is more tolerant of salinity than maize. It is adapted to poor soils and can produce grain on soils where many other crops would fail.

HUSBANDRY OF SORGHUM

Sorghum is a rain fed crop, sown after the onset of the long rain season. Where the seed bed is not fine it is paramount to increase the seeding rate to compensate for poor seed-bed or to allow for unfavorable moisture conditions. A fine seed bed is compulsory for better seedling establishment.

The planting field should be prepared well in advance of sowing. Seed rate is 7-10 kg/ ha or 3-4 kg/acre. Dry planting is highly recommended.  When dry planted, planting depth should be 5 cm but when planting in a moist soil use planting depth of 2.5-4 cm.  Row spacing is 75 cm and distance between plants about 20 cm. For semi arid areas, row spacing should be 90 cm and the spacing between plants is 15 cm. 

Sorghum requires about 20 kg N/ha and 20 kg P/ha at planting time, which can be supplied by alternate cropping with legumes and application of compost or manure. Also intercropping with legumes is recommended with grain legumes such as beans, cowpeas, pigeon peas and green gram. Manure and compost improve organic matter content of the soil, soil moisture retention ability and soil structure.

Manure can be broad cast in the field or applied in planting furrows and mixed with soil before seeds are planted. The standard farm wheelbarrow when full holds approximately 25 kg of dry manure/compost. At a low rate, two wheel barrows are enough for a 10m by 10m area. This translates into 200 wheelbarrows or 5 tons/ha. When aiming for high seed rate, apply 400 wheelbarrows or 10 tons of manure per hectare.

PROPAGATION AND PLANTING OF SORGHUM

Sorghum is normally grown from seed. A fine seed-bed is preferable but is often not achieved. The seed is usually sown directly into a furrow following a plough, but can also be broadcast and harrowed into the soil. Optimum plant spacing depends on soil type and availability of moisture. For favorable conditions, row spacing of 45-60 cm and plant-to-plant spacing of 12-20 cm, giving populations of about 120 000 plants per ha, are normal. For drier or less fertile conditions, wider spacing and lower plant populations are usually optimal. The seed rate varies from 3 kg/ha in very dry areas to 10-15 kg/ha under irrigation. Occasionally, seedlings are grown in a nursery and transplanted into the field early in the dry season, e.g. on the floodplains round Lake Chad in Africa
