Effect of integrated plant nutrient supply (IPNS) system on growth, yield attributes and quality parameters of pigeon pea (Cajanus cajan (L) Millsp.) in vertisol

Abstract

The present field experiment was conducted at Research Farm, Department of Soil Science, College of Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during Kharif 2023-24 find out the effect of integrated nutrient management practices on growth and yield and quality parameters of pigeon pea (Cajanus cajan (L) Millsp.) in vertisol. The experiment was laid out in Randomized Block Design (RBD) with three replications. There are 8 treatments combinations. Seed treatment of Pigeon pea done with Rhizobium and PSB @ 10 ml kg-1 seed before sowing. Among all the treatments, Application of 100% RDF (N: P2O5: K2O) + Vermicompost @ 2.5 t/ha + Rhizobium @ 10 ml/kg + PSB @ 10 ml/kg + ZnSo4 @ 25 kg/ha significantly superior to control in respect to growth parameters i.e. Plant height, Number of branches and Number of Pods. The highest protein content & test weight and seed & straw yield were obtained with 100% RDF (N: P2O5: K2O kg ha-1) + Vermicompost @ 2.5 t/ha + Rhizobium @ 10 ml/kg + PSB @ 10 ml/kg + ZnSO4 @ 25 kg/ha followed by 100% RDF (N: P2O5: K2O kgha-1) + Vermicompost @ 2.5 t/ha + Rhizobium @ 10 ml/kg + PSB @ 10 ml/kg and lowest seed and straw yield was registered in absolute control.
