Abstract:

A field experiment was conducted during Khari season of 2014 on loamy sand soil to study the effect of phosphorus levels and bio-fertilizers on productivity, nutrient content and uptake of urban. Experiment consisted of four treatments of phosphorus levels (0, 20, 40 and 60 kg/ha) and four treatments of bio-fertilizers (control, PSB, VAM and PSB + VAM) thereby making sixteen treatment combinations tested in randomized block design with three replications. Result indicated that application of phosphorus up to 40 kg/ha significantly increased grain and straw yield, net returns, protein content in grain, nitrogen, phosphorus and potassium concentration in grain and straw and total uptake of nitrogen, phosphorus and potassium over preceding levels and remained at par with 60 kg/ha. Whereas, raising the level of phosphorus from 0 to 20 kg/ha registered the highest agronomic efficiency, apparent recovery and physiological efficiency of phosphorus after that, it showed significant decline up to 60 kg/ha. Combined inoculation of seed and soil with PSB + VAM significantly increased the grain and straw yield, net returns, nitrogen, phosphorus and potassium concentration in grain and straw, their total uptake as well as protein content in grain and available phosphorus in soil after crop harvest over PSB, VAM and control, whereas, the highest agronomic efficiency and apparent recovery of P recorded under PSB + VAM inoculation and physiological efficiency under control.
