Effects of PGPR blended biochar and different levels of phosphorus on yield and nutrient uptake by chickpea

Abstract

The experiment was conducted during rabi season of 2012-13 at the Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi (U. P.).This manuscript focuses on the PGPR blended biochar and different levels of phosphorus on yield and nutrient uptake by chickpea (Cicer arietinum). Experiment was laid out in CRD with four replications and nine treatments. Three phosphorus levels (0, 30 and 60 kg P2O5/ha) were evaluated in pots. The experimental results showed that application of 60 kg P2O5/ha significantly improved agronomic traits as compared to other treatments. The application of 60 kg P2O5/ha with micronutrient blended biochar with PGPR found 52.14% higher grain yield over control. Nitrogen and phosphorus content in grain (4.03 and 0.503%, respectively) found in treatment T9 was higher than the control.These results suggested that the application of 60 kg P2O5/ha with micronutrient blended biochar with PGPR significantly affected the yield of chickpea.
