Abstract: The experiment entitled “Response of green gram (Mung) (Vigna radiata L.) varieties to different phosphorus levels” was conducted at the at Agronomy Research Farm of the “Narendra Deva University of Agriculture and Technology, Narendra Nagar, Kumarganj, Faizabad (U.P.). The farm is situated at south-east of Faizabad-Raibareilly road in a main campus of the university which is 42 Km. away from Faizabad city. During the kharif season (June-September) of 2016 to find out the Impact of varieties and phosphorus levels on the relative yield of kharif mungbean (Vigna radiata (L.) Wilczek. The experiment was laid out in Factorial Randomized Complete Block Design with four replications and constitute of four levels of phosphorous viz., 20 kg P₂O₅ ha^-1, 40kg P₂O₅ ha^-1, 60kg P₂O₅ ha^-1, control (no phosphorous application) in 25 varieties ie NDM-1, Meha, Samrat, Amrit, KM 1, Mohni, Pannt mung-1, Pant mung-2, PDM-11, Pusa-105, Pusa Vaisakhi, Sabarmati, Sunaina, Varsa, Type-1, Type-44, Type-51, ML-1, ML-5, ML-131, CO-4, Jawahar-45, K-851, Gujrat-1 and Gujrat-2 of mung. Results revealed that most of the growth characters such as initial plant population, plant height, number of leaves, number of branch plant^-1 were significantly increased due to application of phosphate fertilizer over control on the similar way application of phosphorous significantly increased the yield and also. The highest grain yield (11.02q ha^-1 during 2014-15 and 11.31q ha^-1 during 2015-16) was obtained with 60 kg P²O⁵ ha^-1 having an increase of 31.85% and 31.92% over the control during first and second year respectively and the lowest with no phosphorous application (7.51 and 7.70q ha^-1 in first and second years of investigation). Grain yield obtained by application of 40kg P₂O₅ was statistically at par with that of 60kg P₂O₅ ha^-1.
