Yambean

Season: Pre rabi
Soil type: Fertile, well drained sandy loam soil is best suited for cultivation of yam beans.
Sowing time: Under rainfed condition second fort night of August to September is optimum time of planting. Under irrigation condition sowing can be continued during October. July is optimum time of sowing of seed crops.
Seed rate: 8-16 kg/acre depending of time of sowing.
Methods of sowing: Sowing of seeds on ridges at 30x30cm spacing with sowing depth of 5-6cm results better tuber yield
Nutrient management:
Basal: FYM 4t + Urea 53kg+ SSP 150 kg + MOP 40kg/acre, Top dressing at 30 DAS: Urea 53 kg + MOP 40 kg per acre,
Weed management: First soil loosening and weeding should be done at 25-30 DAS. If needed second weeding can be done at 40-45 DAS.
Nipping: Nipping of flower either manually or by spaying 2,4-D (50ppm) at flower initiation results better yield of tubers.
Water management: Yam bean normally grown under rainfed condition. Do not allow water stagnation in yam bean field. Maintain sufficient soil moisture at tuber initiation and bulking stage for optimum tuber yield.
Harvesting: The crop becomes ready in 90-100 days after sowing. In a well-managed crop farmer can get 12-14 t/ acre
