Rainwater Management

• Grow bunch groundnut at 30 cm distance between rows having three rows on broad bed of 90 cm and furrow of 45 cm for getting higher yield to check runoff and soil loss.
• Adopt two to four interculturing along with deep ploughing for higher yield of groundnut and maximum moisture conservation.
• Sow spreading groundnut or grow Dicanthium annulatum on fallow lands to check runoff and to minimize soil loss on sloppy land. 
• Construct a farm pond of minimum 450 cu. m size for 1 ha cultivable area.
• Apply FYM @ 10 t/ha and kaolin @ 4% spray (400gm/10 liter water) at dry spell in groundnut and Bt. Cotton for higher productivity and maximum rain and crop water use efficiency.
• Apply hydrogel @ 2.5 kg/ha before sowing (1:10 mixture of hydrogel and sand through drilling in the furrow) and FYM @10 t/ha for mitigating moisture stress during dry spells and obtaining maximum rain water use efficiency, higher groundnut productivity and net returns

Cropping Systems

• Groundnut  + castor (3:1 or 6:1), groundnut  and  sesame (6:3), cotton + groundnut/ green gram/ black gram/ sesame/ cowpea (1:1), groundnut  + pigeon pea (3:1),  pearl millet + pigeon pea  (2:1 or 4:1), sorghum + pigeon pea  (1:1), castor + cowpea/green gram (1:1) are economically viable intercropping systems.
• Adopt paired row planting of castor + green gram (2:1) OR paired row planting of cotton + groundnut (2:1) for getting higher yield and net return.
• Intercrop cowpea or sesame or groundnut or green gram in cotton (1:1)for getting higher yield and net return.

Crop Management

• Semi spreading groundnut (GG-20), bunch groundnut (GG-5 and GJG-9), cotton (G. cotton hy.-8), pearl millet (GHB-719,744 and 732) and castor (GAUCH-1 and GCH-7) keeping row spacing as 60, 45, 120, 60 and 90-120 cm, respectively for maximum yield.

• For effective weed management in kharif groundnut, spray pendimethalin @ 1.0 kg/ha (in 500 liter water) as pre-emergence + two hand weeding at 30 and 45 days after sowing.
• Spray fluchloralin @ 0.9 kg/ha (500 liter water) as pre-emergence + two hand weeding at 40 and 60 days after sowing  for weed management in groundnut + castor (3:1).
• In groundnut crop give supplementary irrigation at soil moisture deficit of about 40 % (about 20% soil moisture content)
• Detopping at 75 DAS and foliar spraying of Ethrel @ 50 ppm at 90 DAS in cotton.
• Spray of Gibberellic Acid (GA3) 1 gram/10 litre water (@ 100 ppm) at flowering stage and pod development stagesof  blackgram in kharif season
• Keep groundnut crop weed free through hand weeding and inter-culturing at 15, 30, 45 and 60 DAS or for chemical weed control, apply POE Quizalofop-ethyl @ 40 g/ha at 20 DAS + 1 HW & 1IC at 40 DAS or PE of Oxyfluorfen @ 0.24 kg/ha + 1 HW & 1 IC at 40 DAS

Energy Management

• Plough 20 cm depth in alternate furrows (alternate year) and apply FYM @ 5 t/ha + RDF give higher yield of groundnut.
• Multipurpose tool bar can be used for three operations (seed +fertilizer drilling and covering) at a time. Earthening up attachment can also be used with this implement.

Recycling of organic/farm waste

• Prepare enriched compost by recycling of crop residues with addition of bio-inoculants (composite compost culture, Azotobacter and PSM) @ 500 g each per tonne of organic residues as well as urea @ 0.5 per cent, rock phosphate @ 1.0 per cent P2O5 and pyrite @ 5 per cent.
• Recycle of cotton stalk by chopping into small pieces of 5-6 cm using cotton shedder and composting with addition of compost culture @ 500 g per tonne, urea (N @ 0.5%), cow dung @ 20% as well as Azotobactor and PSM) @ 500 g each per tonne during first turning of cotton stalk to get enriched compost within 120 days.

Nutrient management

• Apply 80-40; 90-30; 20-40; 40-0; 30-30 and 50-25 kg NP/ ha in pearl millet, sorghum, pulses, cotton, castor and sesame, respectively for getting higher returns.
• Apply 50 % and 100% RDF to groundnut and castor respectively in groundnut + castor (3:1) for higher return.
• Apply 80 kg nitrogen/ha to cotton and 25 kg nitrogen and 12.5 kg phosphorus/ha to sesame crop under hybrid cotton + sesame intercropping for getting higher yield.
• Apply 100 % RDF (80-40 kg NP/ha) only to the pearlmillet in groundnut-pearl millet crop rotation.
• Apply 40 kg N and 20 kg P2O5/ha to sorghum under Ghed area for obtaining higher yield and net return as well as sustaining soil fertility. The nitrogen should be applied in two equal splits i.e. 50% as basal at the time of sowing and 50% as top dressing by drilling in 10 cm soil depth at 45- 50 days after sowing
• Apply 100-30-60 N-P2O5-K2O kg/ha to Bt. cotton for obtaining higher yield and net return as well as sustaining soil fertility under rainfed conditions. The phosphorus and potash should be applied as basal, while nitrogen should be applied in three splits i.e. 25 % as basal at the time of sowing, 50 and 25 % as top dressing at 35-40 and 60-65 days after sowing, respectively by drilling in 10 cm soil depth.
