Abstract:
An experiment was carried out during kharif season of 2020 to evaluate the performance of phosphorus and molybdenum levels on yield and economics of blackgram (Vigna mungo L.) done at Crop Research Farm, SHUATS, Prayagraj. The experiment contains three doses of phosphorus (20, 30, 40 kg P₂O₅ /ha) and three dose of molybdenum (Seed treatment of 8g/kg seed, Foliar spray of 0.4% at 15 DAS and 0.8% at 25 DAS) which was followed in a Randomized Block Design and total nine treatments were designed and replicated thrice. Results revealed that plant height (45.53 cm), number of branches (5.33/plant), number of nodules per plant (25.20), dry weight (3.99 g), crop growth rate (3.40 g/m²/day) and grain yield (1369.25 kg/ha) recorded significantly higher with the application of 40 kg/ha P₂O₅ along Mo (Foliar spray 0.8% at 25 DAS). However, highest gross returns of ₹ 87,499.03/ha and net returns ₹ 63,629.03/ha and B:C ratio of 2.67 were recorded in 40 kg/ha P₂O₅ + Mo (foliar spray 0.8% at 25 DAS), respectively.
