Field preparation | Prepare good seed bed for proper germinationPlough the soil 2-3 times and then plankEnsure seed bed to be free of weeds and clodsFor summer crop, till after irrigation |
Sowing time | Kharif: mid June to 1st week of JulyRabi: December – JanuarySummer: 1st fortnight of March |
Seed rate | Kharif: 15-20 kg seed/haRabi: 25-30 kg seed/ha |
Spacing | Kharif: Inter row – 45 cm; inter plant – 5 cmRabi: inter row – 30 cm; inter plant – 5 cm |
Method | Manual: Broadcast behind ploughMechanical: Use a multicrop seeder |
Seed treatment | For soil and seed germination related issues: | Seed treatment with Trichoderma Sp. @ 5-10 gms/kg of seed |
For sucking pest control: | Imidacloprid 70 WS @7g/kg |
Mix well with seed before sowing |
Nutrient management | Before sowing | Apply 8-10 tons/ha of compost or farm yard manure 15 days before sowing |
At sowing | 15 – 20 kg Nitrogen and 30 – 40 kg Phosphorus as 100 kg DAP/ha |
Fertilizer should be placed 2-3 cm below the ground at the time of sowing |
Water management | 3 – 4 irrigations required1st irrigation at 20 – 25 days after sowingIrrigate every 15 – 20 days post first irrigationLifesaving irrigation at early pod formation stageAvoid water logging |
Weed management | Weed at least twice: 20 – 25 days after sowing, 40 – 45 days after sowingChemical control: Pendemethelin 30%EC@0.75/kg a.i/ha in 400 – 600 ml of waterUse flat fan nozzle for spraying |
Disease management | |
Yellow mosaic virus | Causal organism | Gemini group of viruses transmitted by white fly |
Symptoms | Tender leaves show yellow spotsOlder leaves turn yellow |
Control | Rogue out diseased plantsControl white flyTriazophos 40 EC@2.0 ml/l orOxydemeton methyl 25 EC @2 ml/lit of waterSpray at 10 – 15 days intervalsPlant resistant varieties |
Leaf curl | Causal organism | Mung bean leaf curl virus |
Symptoms | Enlargement and crinkling of leaves seen 3-4 weeks after sowingLeaves later become leathery |
Control | Rouge out infected plantsApply Imidacloprid 70 WS@5ml/kgFoliar spray of dimethoate 30 EC@1.7 ml/ha at 30 days after sowingUse flat fan nozzle for spray application |
Insect pest management | |
White fly | Causal organism | Bemisia spp. |
Symptoms | Downward cupping on leavesHoney dew on leavesBlackening of leaves |
Control | Triazophos 40 EC@2.0 ml/l orOxydemeton methyl 25 EC@2.0 ml/lSpray at 10 – 15 days intervalsUse sticky trap for insects |
Stem fly | Causal organism | Ophiomyiaphaseoli |
Symptoms | Dropping off of the first two leavesYellowing of panicle |
Control | Follow clean cultivation practicesPlant resistant varietiesPractice seed treatment for sucking pestsSpray Imidacloprid 17.8 SL@0.2 ml/lt or Thiomethoxam 25 WG @0.3 g/lt 15 days after sowing |
Harvest | Harvest when more than 80% pods are matureHarvest in two rounds to avoid shattering losses |
Threshing | Beat with stick or trample using bullocksUse a pulse thresher |
Drying | Clean seeds should be sundried for 3-4 days to bring down the moisture levels to 8-10% |
Storage | Store in appropriate storage containers like the painted pot or an air tight bagSeeds can be stored in the IRRI super bag |
