Abstract:
A field experiment entitled, “Effect of nutrient management on nutrient content and uptake by Indian bean in Indian bean-summer sorghum cropping sequence” was conducted at College farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari (Gujarat) during kharif and rabi season of 2019-20 and 2020-21. The field experiment consisted of nutrient management treatments viz., T₁:- RDF (25 N - 50 P₂O₅ - 00 K₂O kg/ha), T₂:- 75% RDF, T₃:- 75% RDF + Vermicompost @ 2 t/ha, T₄:- 75% RDF + FYM @ 5 t/ha, T₅:- 75% RDF + Biocompost @ 5 t/ha, T₆:- 75% RDF + Vermicompost @ 2 t/ha + NPK consortia @ 1 litre/ha soil treatment, T₇:- 75% RDF + FYM @ 5 t/ha + NPK consortia @ 1 litre/ha soil treatment and T₈:- 75% RDF + Biocompost @ 5 t/ha + NPK consortia @ 1 litre/ha soil treatment to Indian bean in rabi season and all these treatments replicated three times in randomized block design. On the basis of two-year pooled results, it was observed that treatment receiving 75% RDF + Biocompost @ 5 t/ha + NPK consortia @ 1 litre/ha soil treatment (T₈) recorded significantly higher nutrient content (N and P₂O₅) and uptake (N, P₂O₅ and K₂O) as well as its total uptake and which was remained almost at par with application of 75% RDF + Vermicompost @ 2 t/ha + NPK consortia @ 1 litre/ha soil treatment (T₆) and 75% RDF + FYM @ 5 t/ha + NPK consortia @ 1 litre/ha soil treatment (T₇). While, the lower nutrient content (N and P₂O₅) and uptake (N, P₂O₅ and K₂O) were found with treatment receiving RDF (T₁)by seed and stover of Indian bean as well as its total uptake also. However, K₂O content in seed and stover of Indian bean was not significantly influenced by various nutrient management treatments.
