Abstract
Background: A field experiment was conducted during two consecutive Rabi (winter) seasons of 2016-17 and 2017-18 at Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat, India to assess the impact of wheat varieties and integrated nutrient management practices on nutrient content and uptake and soil nutrient status. 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: Experiment was laid out in a Factorial RBD with three replications, consist of four wheat varieties viz. GW 273, GW 322, GW 451 and GW 496 and six integrated nutrient management (INM) practices viz. control, 100% RDF, 100% RDF + Azotobacter + PSB, 75% RDF + Azotobacter + PSB, 75% RDF + Azotobacter + PSB + ZnSO4 and 50% RDF + 25% N through FYM + Azotobacter + PSB + ZnSO4. Result: The pooled results indicated that uptake of nitrogen, phosphorus and potassium by grain and straw, grain yield and straw yield were found higher with wheat variety GW 451 as compared to other wheat varieties. Nutrient content in grain and straw was not significantly affected by different wheat varieties. Among nutrient management practices, nitrogen, phosphorus and potassium content, uptake, grain yield and straw of wheat were significantly higher under application of 100% RDF + Azotobacter + PSB. Further, result revealed that different wheat varieties did not bring any significant variation in available nitrogen, phosphorus, potassium, zinc and organic carbon content in soil. Moreover, highest available nitrogen and phosphorus in soil was recorded with the application of 100% RDF + Azotobacter + PSB. However, significantly higher organic carbon and zinc content in soil was observed under 50% RDF + 25% N through FYM + Azotobacter + PSB +ZnSO4.
