Residual Effect of Wheat Varieties and Integrated Nutrient Management on Productivity and Profitability of Green Gram under North Gujarat Agro-climatic Condition

Background: A field experiment was conducted during two consecutive summer seasons of 2016-17 and 2017-18 at Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat to assess the residual effect of wheat varieties and integrated nutrient management on growth, yield, economics and quality of green gram ( Vigna radiata L.). The soil of the experimental plot was loamy sand in texture, low in organic carbon (0.24%), available nitrogen (159 kg/ha) and Zn (0.41 mg/kg), medium in available phosphorus (38.90 kg/ha) and high in available potash (287 kg/ha). Methods: During the period 2016-17 to 2017-18 the experiment was laid out in a Factorial RBD with three replications, consisted of four varieties GW 273 (V1), 1 ), GW 322 (V2), 2 ), GW 451 (V3) 3 ) and GW 496 (V4) 4 ) and six integrated nutrient management control (N1), 1 ), 100% RDF (N2), 2 ), 100% RDF + Azotobacter+ + PSB (N3), 3 ), 75% RDF + Azotobacter+ + PSB (N4), 4 ), 75% RDF + Azotobacter+ + PSB + ZnSO4 4 (N5) 5 ) and 50% RDF + 25% N through FYM + Azotobacter+ + PSB + ZnSO4 4 (N6). 6 ). Result: The pooled results indicated that among the residual effect of nutrient management practices, application of 50% RDF (RDF; 120:60:00 kg NPK/ha) + 25% N through FYM + Azotobacter+ + PSB + ZnSO4 4 significantly improved growth parameters, yield attributes, seed yield (669 kg/ha) and stover yield (1406 kg/ha) over control and gained the highest net return (`18538/ha) and benefit: cost ratio of 0.88.
