Abstract: A field experiment was conducted during 2016-17 to evaluate the influence of integrated use of chemical fertilizers, FYM and bio-fertilizers on crop productivity and soil fertility under onion. The treatments were control (T1), 50% NPK (T2), 50% NPK + FYM (10 tons ha-1) +VAM (10 kg ha-1) (T3), 100% NPK (T4), 100% NPK + FYM (10 tons ha-1) + VAM (10 kg ha-1) (T5), 150% NPK (T6), 150% NPK + FYM (10 tons ha-1) + VAM (10 kg ha-1) (T7) and FYM (10 tons ha-1) + VAM (10 kg ha-1) + PSB + Azotobacter (T8). Application of 100% NPK along with FYM (10 tons ha-1) and VAM (10 kg ha-1) i.e. T5 significantly increased the growth and yield as well as soil fertility status as compared to chemical fertilizers alone. Significantly higher plant height, number of leaves per plant, bulb diameter and bulb yield of onion and soil properties in terms of organic carbon, available NPK and S were obtained with application of 100% NPK + FYM (10 tons ha-1) + VAM (10 kg ha-1) (T5) in comparison to other treatments. Significantly higher NPKS uptake was also observed with T5. This experiment indicated the superiority of integration between chemical fertilizers; FYM and bio-fertilizer (VAM) over chemical fertilizer alone at all level of fertility.
