Bio-organic amendments improve soil fertility and sustainable crop productivity. The application of integrated nutrient management (INM) bio-organic amendments couple with chemical fertilizers is one of the promising strategy that not only enhances crop productivity on sustainable basis

Therefore a field experiment was conducted to evaluate the productivity enhancement of wheat by combined application of Biofertilizer and chemical fertilizers including Zinc Sulphate and Boric Acid on growth and nutrient concentration of wheat variety (Faisalabad 2008) directly sown in a saline sodic soil (ECe=4.92 dSm-1, pH=8.22 and SAR=16.15 dSm-1) at Soil Salinity Research Institute (SRRI) Farm, Pindi Bhattian during Rabi 2019-20. Treatments were arranged in randomized complete block design (RCBD) with three replications. The crop was harvested at maturity, data on tillering, plant height, number of grains spike-1, 1000-grain weight, straw and wheat grain yields were recorded. N, P, K, Zn and B concentration in grain and straw were estimated using atomic absorption spectroscopy. Wheat productivity was significantly (p ≤ 0.05) increased by INM. Wheat grain yield was the maximum (4.76 tha-1) at the application of 120 kg N, 90 kg P 60 kg K, 5 kg Zn and 1kg B ha-1 along with Biozote and it was registered 35% more than Farmer practice. This study confirms that INM has tremendous potential of plant nutrients supply for productivity enhancement of Wheat on sustainable basis.
