Response of ten mungbean genotypes 98-CMG-003, 98-CMG-016, 98-CMG-018, L1/P5/89, NM-1, BRM-195, BRM-202, M-1, M-6 and NM-92 to three phosphorus level viz. 30, 60 and 90 kg ha-1 was studied under field conditions during kharif 2001. The genotype BRM-202 gave significantly highest grain yield of all other genotypes due to higher leaf area index. Various levels of phosphorus significantly affected the number of plants m-2, number of pods plant-1, plant height, number of grains pod-1, 1000 grain weight, grain yield, total biomass and leaf area index. phosphorus level of 90 kg ha-1 produced the maximum grain yield.
