Seed rate: Bushy type: 20-25 Kg/ha,
Trailing type: 4-5 Kg /ha
Seeds available with VFPCK: Lola, Kanakamony, Anaswara
Seed Treatment: Cowpea seeds should be inoculated with Rhizobium and pelleted with lime. 10g Rhizobium +2.5% starch solution + 50-100g calcium carbonate for 1 kg seed.Dry the inoculated seeds under shade over a clean paper or gunny bag and sow immediately.
Spacing: Bushy/semitrailing:1m X10-15 cm. Planting can be done on ridges during rainy season and in channels during summer.
Trailing type: pits at a spacing of 2X2 m, retaining 2-3 plants / pit or
ridges at a spacing of 1.5 m X 50-60cm.
Nutrient management : Apply FYM 20 t/ha. NPK 20:30:10 kg/ha.Half the quantity of N, whole of phosphorus and potash may be applied at the time of final ploughing. The remaining N may be applied 15-20 days after sowing.
Crop Management: Application of Planofix @ 3-6ml in 10 litres water one month after sowing will improve the yield. Approximately 2.5litre solution is required for one cent. Repeat the application 2 months after sowing. Excessive vegetative growth is a problem in some of the varieties. Withhold irrigation and apply Potash to induce flowering.
Pest Management :
Yield: Green pod yield of 10-20tons and grain yield of 1.2-1.5 tons per ha.
Post Harvesting: The pods are then to be precooled in shade to reduce the field heat. They are the tied into small bundles and packed.
