Effect of integrated nutrient management on growth, yield, nutrient uptake and soil nutrient status of summer green gram (Vigna radiata L.) under south Gujarat conditions

Abstract

A field experiment was conducted at College Farm, Navsari Agricultural University, Navsari (Gujarat) during the summer seasons of the years 2018 and 2019. The soil of the field was clayey in texture, slightly alkaline (pH 7.9), low in organic carbon (0.41%) and available nitrogen (199.86 kg/ha), medium in available phosphorus (39.43 kg/ha) and high in available potassium (302.88 kg/ha). Six treatments were imposed in summer green gram viz. absolute control (T1), 100% RDF (20:40:0) (T2), 100% RDF + biocompost @ 5 t/ha (T3), 100% RDF + biocompost @ 5 t/ha + PSB @ 2.5 l/ha (T4), 50% RDF + biocompost @ 2.5 t/ha (T5) and 50% RDF + biocompost @ 2.5 t/ha + PSB @ 2.5 l/ha (T6). These treatments were replicated four times in randomized block design. Treatments T3, T4 and T6 performed equally good and recorded significantly higher growth attributes, yield attributes, seed & stover yield, nutrient uptake (NPK) and available nutrient status in soil.
