Abstract:
A field experiment was carried out in Rabi, 2017-18 and continued to Rabi 2018-19 at research farm, college of agriculture and research station, Raigarh (C.G.). The experiment was laid out in randomized block design with three replications and consisted as eleven treatments namely (T₁) Control, (T₂) GRD, (T₃) 75% GRD+RB @2.5t/ha, (T₄) 75%GRD+RR @5t/ha, (T₅) 75% GRD+ RR @5t/ha+ FYM @2.5t/ha, (T₆) 75% GRD+ RB @2.5t/ha+ FYM @2.5t/ha, (T₇) T₃+Trichoderma+ FYM @2.5t/ha, (T₈) T₄ + Trichoderma + FYM @2.5t/ha, (T₉) 75% GRD+RR @5t/ha + 6%ureaspray, (T₁₀) 75% GRD + RR @5t/ha RB @2.5t/ha, (T₁₁) T₁₀ + 6% urea spray. The Pod yield of groundnut ranged between 1180.07 kgha^-1 to 2299.73 kgha^-1 and 1228.20 kgha^-1 to 2330.15 kgha^-1 during 2017 and 2018, respectively whereas haulm yield of ground ranged between 2611.45 to 4306.76 and 2441.47 to 4275.80 kgha^-1 during 2017 and 2018 respectively. From the study it was concluded that the maximum pod yield was recorded in T₁₁ (T₁₀ + 6% urea spray). Total groundnut crop nutrient uptakes were calculated also as the sum of pod and haulm uptakes. The present investigation recommended that 75% GRD with 5% RR and RB @2.5t/ha + 6% urea application will be helpful productivity, sustainability and economical profitability for rice-groundnut cropping system for inceptisol of Chhattisgarh.
