Abstract:
A field experiment entitled “Nutrient content and uptake of vegetable Indian bean (Dolichus lablab L) as influenced by different INM treatments in Indian bean (v) - pearlmillet (f) sequence” was conducted at college farm of N. M. College of Agriculture, Navsari Agricultural University, Navsari (Gujarat) during the years 2019-20 and 2020-21. The field experiment consisted of integrated nutrient management treatments viz., T₁ - 100% RDN through chemical fertilizer + 5 t ha^-1 of FYM, T₂ - 75% RDN through chemical fertilizer + 25% RDN through biocompost, T₃ - 75% RDN through chemical fertilizer + 25% RDN through biocompost + seed treatment with PSB and Rhizobium biofertilizers, T₄ - 50% RDN through chemical fertilizer + 50% RDN through biocompost, T₅ - 50% RDN through chemical fertilizer + 50% RDN through biocompost + seed treatment with PSB and Rhizobium biofertilizers and T₆ - 100% RDN through biocompost to vegetable Indian bean in rabi season and replicated four times in randomized block design. On the basis of two year pooled results, the N content as well as N, P and K uptake by green pod and stover of vegetable Indian bean was significantly recorded higher values with respect to the treatment T₁while, P and K content in both green pod and stover was found to be non significant. However, the treatment T₆ recorded lower values with respect to N, P and K content and uptake by both green pod and stover. Significantly higher organic carbon content, available N, P₂O₅ and K₂O in soil after harvest of vegetable Indian bean was recorded in the treatment consisting of 100% RDN through chemical fertilizer + 5 t ha^-1 of FYM (T₁) during both the years whereas, INM treatments failed to exert their significant influence on bulk density of the soil.
