Plant Nutrient Management

• Yield of 1t green gram/ha removes 40kg N, 3-4 kg P, 10-12 kg K, 1-1.5 kg Ca, 1.5-2 kg each of S and Mg.
• Requires 15t/ha FYM, 10-15:30-50:30 kg N, P2O5 and K2O/ha.
• It is beneficial to apply 15-25kg ZnSO4, 20-30kg S and 1 kg Sod. Molybdate per ha.
• P- improves primary yield components such as pods/plant, seeds/pod and seed weight, increased nodule number.
• Foliar fertilization (3% DAP)- improve protein content, pods/plant, shelling %, grain wt.
• Mo- improves nodulation, N-fixation and higher yield.
• In Nepal, 4-6t/ha FYM; 20:20:20 kg NPK/ha.

Irrigation

• Raised as rainfed crop during summer and rainy season.
• Critical stages: flowering and pod development.
• 1-2 irrigation at critical stages.
• Water logging at critical stags causes yield reduction to the extent of 60-72%.
• Excess or stress at flowering and development results in reduction on pod number and seed weight.
• Irrigate at an interval of 15 days in summer and drought condition.

Weed Management

• Cause loss upto 25-50%.
• 1-2 hand weeding: 1st at 2-3 leaf stage and 2nd during intense vegetative growth.
• Herbicides: Nitrofen @ 1.0-1.5 kg a.i./ha, Fluchloralin @1-1.5 kg a.i./ha, Alachlor @2 kg a.i./ha as pre-emergence; Pendimethalin @ 1 kg a.i./ha as pre-plant.

Harvesting and threshing

• Ready to harvest when pods turn black or brown in color.
• Better to pick up matured pods once and subsequently whole plant with remaining pods.
• Harvest manually by picking pods or cutting near the ground (in early morning to avoid shattering) or using combine harvester.
• Sun dry harvested pods or plants with pods to reduce moisture content and thresh by beating with stick or trampling.
• Lower the seed moisture to 12% for safe storage.
• Store in airtight metallic bins and place in cool and dry places.

Yield

• 2-1.5 t/ha grain under well management.
