abstract
A field experiment was carried out at Regional Research Station, Anand Agricultural University, Anand, Gujarat during the kharif and summer season of 2021-22 and 2022-23, to study the response of integrated nutrient management on Bt. cotton-groundnut cropping sequence. The experiment was laid out in a randomized block design in Bt. cotton with 5 treatments and 4 replications, while split plot design was laid out in summer groundnut with 10 treatments and 4 replications. Application of 75% RDN through inorganic fertilizer + 25% RDN through vermicompost along with Bio NPK consortium to kharif cotton significantly increased the plant height, monopodial branches per plant, sympodial branches per plant, seed cotton yield and stalk yield. In succeeding summer groundnut, residual effect of 75% RDN through inorganic fertilizer + 25% RDN through vermicompost along with Bio NPK consortium and 100% RDF significantly increased plant height, number of branches per plant, pods per plant, pod yield and haulm yield.
