Abstract

The purpose of the one-season field trial was to examine how integrated nutrient management affected the growth, yield and net income of the lentil crop. It was carried out at the Agriculture Research Block of the SGRR University (SAS-SGRRU), Dehradun, Uttarakhand, during the Rabi season of 2021–2022. Eight treatments viz: Control (T1 ); N:P:K @ 15:20:0 kg ha^-1 (T2 ); N:P:K @ 15:20:20 kg ha ^-1 (T3 ); N:P:K @ 15:40:20 kg ha^-1 (T4 ); N:P:K @ 15:40:20 kg ha^-1 + Rhizobium (T5 ); N:P:K @ 15:20:20 kg ha^-1 + Rhizobium + PSB (T6 ); N:P:K:S:Zn @15:40:10:8.5:10.5 kg ha^-1 (T7 ) and N:P:K:S:Zn @15:40:0:17:21 kg ha ^-1 (T8 ), each replicated three times, were used in the RBD design. The soil of the experimental field was sandy loam with low levels of organic carbon, phosphorus, and potassium that were readily available. It may be advised to increase production and monitory benefit of lentil in valley areas of Dehradun, Uttarakhand, by applying N: P: K @ 15:20:20 kg ha^-1 + Rhizobium + PSB because these treatments considerably increased grain yield, straw yield, harvest index, net income, and B: C ratio.
