An experiment was carried out on sandy loam soil to evaluate the impact of organic manures (farmyard manure, vermicompost, poultry manure and neem cake) and bio fertilizers (Arka Microbial Consortium) on available NPK in soil and nutrient composition of okra fruit during kharif season of 2017- 2018 at vegetable research station, Sri Konda Laxman Telangana State Horticultural University, Rajendranagar, Hyderabad. In organic farming the use of mineral fertilizers is highly restricted; so, for present experimentation virgin soils were selected. Ten treatments were tried out in randomized block design with three replications. Soil chemical parameters viz., available N, P2O5 and N per cent, P per cent in okra fruit were found to be affected significantly due to T10 with FYM (5t ha-1) + VC (1.25 kg ha-1) + NC (125 kg ha-1) + PM (1.25 kg ha-1) + AMC (12.5 kg ha-1). We conclude that chemical fertilizers have adverse effect on soil health and environment, so it is not advisable to use. Organic manures and biofertilizers can activate the microbial and enzymatic activity of the soil thus increases the soil physico-chemical properties, residual nutrients concentration and also nutrient composition of okra fruit.
