Adaption of improved agronomic practices in groundnut such as use of drought tolerant variety Dharani, maintaining optimum plant population by adapting proper seed rate @ 150 kgha^-1 (30 cm x 10 cm), seed treatment with recommended chemicals, recommended dose of fertilizer i.e., NPK @ 20:40: 50 kgha^-1 at the time of sowing and top dressing of 500kg gypsum per ha at the time of flowering, application ZnSO₄ @ 25 kgha^-1and Borax @10 kg ha^-1 at the time of sowing, pre emergence application of herbicide Pendimethalin @ 1 Kg a.i ha^-1 with three rows of border crop of Jowar, In red gram improved wilt tolerant variety TRG-59, Thinning and application of 20-50 N,P kgha^-1and suitable and timely plant protection measures.
