HOW TO GROW GREEN GRAMS IN KENYA

Green grams are best grown at an altitude of 0-1600m above sea level well adapted to sandy loam and clayey soils at pH range of 5.5-7.5. They are drought tolerant with rain fall requirement range between 350- 700mm/annum. Heavy rain fall results to increased vegetative growth with reduced pod setting and development. Most parts of Kitui County are favorable for growing green grams.

There are various varieties of green grams grown in Kenya listed below

  • KS20 (uncle) – matures in 80-90days, pods turn brown when dry while grains are dull green in colour and bigger in size compared to n26 produces 3 to 4 bags of 90kg per acre
  • N26 (nylon) – matures in 60-65 days, pods are black when dry and grains are shiny green in colour. produces 3 to 4 bags of 90kg per acre

PLANTING

Land should be ploughed during the dry spell to allow for aeration and expose soil borne pests to die. Soil clods should be broken to medium tilth to create a soil structure that encourages seedlings emerge/germinate uniformly and rapidly. Manure should be applied at a rate 200 wheel barrows per acre. Terracing should be done during land preparation to reduce surface run off and moisture retention for crop sustenance.

Propagation of green grams is by seeds. Seeds are planted at a spacing of 45*15cm, a depth of about 3-5cm, An acre needs 4-6kg of green gram seeds. Germination occurs within 5-7 days and this depend on the variety and environmental factors. When using oxen plough for planting, place the seed at the side of furrow. Practice crop rotation because green grams have toxic residues and disease organisms that may affect the crop.

Foliar feeds should be applied before flowering and at fruiting stage to boost yield.

After planting your green grams regulars farm practices continues which include;

AphidsThey feed on young plants, leaflets, stem and pods of
green grams.
Attacked young leaves become twisted

Pod borersFeeds on leaves by scrapping tissue
Bore into the pods and feed on the seeds
They also cause damage to flower buds and flowers
Check with agro-dealers for suitable pesticide
White fliesThey suck plant sap leading to retarded growth
Attacked leaves become shrinked.
Check with agro-dealers for suitable pesticide
CaterpillarsAttacked leaves and pods are left with windows
The pests can be seen moving on the plant
Check with agro-dealers for suitable pesticide

Physiological maturity harvesting is the stage of growth in which the plant has completed its physiological development or when it has developed enough to provide a useful products to the farmer.

You can pick and dry individual pods or uproot the whole plant and dry it for about two days, then thresh and clean. Harvesting is the most expensive process in growing green grams. Threshing –can be done using either mechanical or manual methods, in mechanical u can use pulse thresher which makes work easier and faster, manually u can use beating stick.
