Effect of phosphorus & bio-organics on quality and symbiotic efficiency of black gram (Vigna mungo L.)

A field experiment was conducted at Instructional Farm, Rajasthan College of Agriculture, Udaipur (Rajasthan) in kharif 2016 on sandy clay loam soil which is slightly alkaline in nature, to asses the effect of phosphorus & bio-organics on yield, quality and symbiotic efficiency of black gram (T-9). The experiment was laid out in randomized block design with four replications. There were nine treatments combinations in the experiments. The results of study revealed that application of 40 kg P2O5 ha-1 + 2.5 t vermicompost ha-1 + Rhizobium + PSB showed significantly higher yield, quality and symbiotic efficiency of black gram.
