Effect of Bio-fertilizer on Different Varieties of Black Gram (Vigna mungo L)

Black gram (Vigna mungo L) is a short duration crop belongs to leguminacae family. Black gram is rich in protein (25-26%) and grown as intercrop, catch crop also as solo crop. It is also called as urd bean. In India the area under black gram cultivation is 3.30 million ha producing 1.60 million tonnes, with the mean productivity of 0.49 kg ha -1 and contributes 11% of total production in the country. Black gram is one of the important crops among the pulses crop. English word pulse is taken from the Latin Puls, meaning pouage or thick pap. The pulses are a large family and various species are capable or surviving in very different climates and soils. Pulses are cultivated in all parts of the world and they occupy an important place in human diet. Blackgram (Vigna mungo L.) is one of the important pulse crops grown in India. Pulses are the cheapest source of quality protein for human being. Blackgram is also grown as a cover crop as well as catch crop due to short duration. The importance of phosphorus application to black gram crop has been recognized since long (Patil and jadhav, 1994).
