- This video highlights best practices involved in farming soybean. it features land preparation, planting, weed control, disease and pest control.
Soybean is a legume vegetable of the pea family that grows in both tropical and temperate regions. Soybean has protein content of 36%, over 30% carbohydrate and Oil. It is an important crop for producing edible oil. It has good amount of dietary fibre, vitamins and minerals.
It is a good protein substitute for protein comparable to meat as protein source. It is
used for feed formulation in animal feed
Cultivation-
Soybean requires temperatures of between 27-35C and rainfall of 30-125cm per year.
It requires abundant sunshine and a rich sandy loamy soil that is well well drained with a pH of 6-6.5. Soybean tap root goes deep so it needs loose soil to penetrate easily. Land preparation includes stomping, harrowing and ridging done in sequenceTrees and stumps must be removed for adequate sunlight.Soybean requires seed dressing before planting
Planting can be done manually or mechanically. Early planting should take place in April and late planting should happen in July-early August.
Dig 2-4cm deep and plant 2 or 3 seeds with a spacing of 25cm X 90cm or 30cm X 75 cm
Germination occurs 3-5 days after planting. 40-50kg of seeds is needed per hectare
Your choice of seeds should depend on the targeted market for your product. Target high oil content seeds if your target market is an oil extraction industry however for the animal feed industry, different seeds are required.
Fertlizer
Apply (SSP) phosphate fertilizer during land preparation at 250kg per hectare. For poor soils, compost can also be added to a land at 5 tonnes per hectare to improve soil fertility in addition to 40kg of urea,60kg of super phosphate and 50kg pottash ash per hectare.
As a legume, it doesn't need much nitrogen but it can be given Nitrogen as a boast growth of seedlings. This gives the plant more branches and leaves.
It is best to add fertilizer at land preparation or at planting.
Baseline herbicides should be added during seed planting or within 3 days of seed planting.
Regular weeding is needed regularly at least twice or trice in the life of a plant. Use of post emergence herbicides that are selective to soybean is advised to manage weed.
Thinning is important to enable adequate spacing between crops. It is advised to be carried out at 3 weeks after planting.
Inter-cropping of soybean is encouraged to minimize the risk of diseases. Inter-cropping with corn(maize) is encouraged. Plant maize keeping rows at 90-100cm apart then plant 3-4 rows of soybean in between the maize rows. Soybean seed and seedlings are susceptible to several diseases. This reduces plant yield and population. It is advised that replanting is carried out if diseases ravage your farm. Common fungi include fusarium. leaves can have rust diseases or viral attacks. Most diseases are transferred to farms by insects so it is important that insecticides are sprayed regularly. Disease resistant seeds should be used. If unavailable treat your seeds with a fungicide before planting. diseases can cause
pod shattering making seed to loose longetivity. Bacteria wilts turns plants to brown. It is advisable to remove affected plants and burn them. Regular visits and inspections can reduce damage from diseases.
Harvest is done when 85-95% pods are yellow/brown and soy seeds are hard. The plant is usually ready for harvest at 85-150 days after planting. It is expected that seeds should have
14-16% moisture at harvest. For late planting (July/August) leaves turn yellow at the end of October/early November. Harvesting is done by breaking the plant stalks with machette or sickle. Do not remove the entire plant as nutrients can be removed from the soil. The harvested pods is then dried for 2-3 weeks and threshed should be done and seeds stored in Jute bags. Yield depends on seeds and management of farm
Nice lesson
