Abstract:
A field experiment was conducted at Agronomy farm, School of Agricultural Sciences and Rural Development (SASRD), Nagaland University, Medziphema during kharif season of 2019, to evaluate the effect of phosphorus and biofertilizers on soil physico-chemical properties and nutrient uptake by black gram (Vigna mungo L. Hepper) under rainfed condition of Nagaland. The treatment comprised of four levels of phosphorus (0, 20, 40 and 60 kg ha^-1) and different seed inoculation (single and dual) of biofertilizer Rhizobium and PSB. Results revealed that combined application of 60 kg P₂O₅ ha^-1 along with dual inoculation of seeds with both Rhizobium and PSB significantly recorded higher uptake of nitrogen in seed (32.97) and stover (41.87­) and phosphorus in seed (3.00) and stover (5.23) over the rest of the treatments. The same treatment had a significant effect on soil physico-chemical properties viz., soil organic carbon (%), available nitrogen (kg ha^-1), available K₂O (kg ha^-1), however, soil pH and available P₂O₅ of the post-harvest soil did not had a significant effect under the same treatment.
