Effect of INM on nutrients uptake in relation to different organic and inorganic fertilizer levels in inceptisol of Northern hills zone of Chhattisgarh

Abstract

A field study was carried out at Krishi Vigyan Kendra Balrampur of Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G) during the rabi seasons of 2021-22 and 2022-23 to evaluate the effect of INM on nutrients uptake in relation to different organic and inorganic fertilizer levels in inceptisol of Northern Hills Zone of Chhattisgarh. The experiment was laid down in Randomized Block Design (RBD) with eight treatments which replicated three. The treatments in the T1 (Control), T2 RDF (180:120:100, N:P205:K20), T3 (75% RDF), T4 (50% RDF), T5 (75% RDF + 2.5 t/ha vermicompost), T6 (75% RDF + 5 t/ha FYM), T7 (50% RDF + 5 t/ha vermicompost) and T8 (50% RDF + 10 t/ha FYM). The highest total N uptake (leaf + curd) was observed in treatment RDF (180:120:100, N:P2O5:K2O), (75% + 2.5 t/ha vermicompost) and (75% RDF + 5 t/ha FYM). The highest total phosphorus uptake (leaf + curd) was observed in integrated treatments (75% RDF + 2.5 t/ha vermicompost), (75% RDF + 5 t/ha FYM) (50% RDF + 5 t/ha vermicompost) and also with RDF (180:120:100, N:P2O5:K2O).The total potassium uptake was the highest by the application of integrated treatments ie. (75% RDF + 2.5 t/ha vermicompost), (75% RDF + 5 t/ha FYM), which were also comparable with (RDF (180:120:100, N:P2O5:K2O).
