Effect of Biofertilizers on Nutrient Uptake by Green Gram [Vigna radiata (L.) Wilczek] under Agri-horti System in Vindhyan Region of Eastern Uttar Pradesh

A field investigation was carried out in Factorial Randomized Block Design during autumn 2018 at agricultural farm, Rajiv Gandhi South Campus, Barkachha, Mirzapur (RGSC), Banaras Hindu University (U.P.) to investigate the impact of fertiliser and biofertilizer on the nutrient uptake by the green gram (V. radiata L.) plant and grain under guava (P. guvajava L.) trees. The twelve year old guava orchard was established in August 2006 with spacing of 7m x 7m. Seven fertilizer combination viz., control, Rhizobium culture, press mud, phosphorus solubilizing bacteria, Rhizobium culture + fertilizer, phosphorus solubilizing bacteria + fertilizer and press mud + fertilizer were applied. Among them application of press mud + fertilizer performed better by recording highest nitrogen content in grain (3.75), nitrogen content in grain (1.50), removal of nitrogen in grain (33.09) Removal of nitrogen in straw (33.03) and phosphorus content in grain (0.41) phosphorus content in straw (0.30), phosphorus uptake in grain (3.62), phosphorus uptake in straw (5.61), and found significantly superior to rest of the treatments.
