Nutrient Uptake and Post-Harvest Soil Nutrient Status of Extra Long StapleCottonas Influenced by Establishment Methods, Intercropping and Nutrient Management


                                A field experiment was conducted at Eastern Block Farm, Department of Agronomy, TNAU, Coimbatore, during the summer of 2019 with the objective of finding outthe nutrient uptakeandthe post-harvest soil nutrient statusof Extra Long Staple (ELS) cotton under methods of crop establishment, intercropping and nutrient management. The experiment was laid out in a randomized block design with three replications. The treatments consisted,viz.T1: Transplanting + Green gram + 75% RDF, T2 : Transplanting + Black gram + 75% RDF, T3 : Transplanting + Onion + 75% RDF, T4 : Transplanting + Green gram + 100% RDF, T5 : Transplanting + Intercrop with Black gram + 100% RDF, T6 : Transplanting + Onion + 100% RDF, T7 : Transplanting + Green gram + 125% RDF, T8 : Transplanting + Black gram + 125% RDF, T9 : Transplanting + Onion + 125% RDF, T10 : Transplanting + 100% RDF, T11 : Direct seeding + Recommended package of practices. Nutrient uptake was higher in transplanted cotton intercropped with black gram followed by thegreen gram with the application of 125% RDF followed by 100% RDF which was significantly influenced by crop establishment techniques, intercropping and different doses of fertilizer level.Available soil nutrients were higher in direct-seeded cotton compared to transplanted cotton.

Key words : Transplanting cotton; Nutrient uptake; Available nutrients
