Abstract: Field experiments were conducted with mung bean (Vigna radiata L. Wilczek) consecutively for three years (2009, 2010, and 2011) in the Crop Research and Seed Multiplication Farm, Burdwan University, West Bengal, India. In the first two years, varietals screening of mung bean under recommended dose of chemical fertilizer (20:40:20) were performed with five varieties with a local variety of mung bean during February to May of 2009. In the second year, one experiment was conducted with six different reduced dose of chemical fertilizer. In the third year, five different method and time of application of biofertilizer were applied to study the effects on agronomic traits and growth attributes of mung bean. The variety PDM-54 a significant higher seed yield along with other yield contributing factors, which was found to be superior to other varieties. In 2010, seed yield was found to be the best for 30% less nitrogenous and 25% less phosphate fertilizer along with recommended dose of chemical fertilizer. In 2011, the best yield was given by the treatment of basal @ 0.75 kg ha-1 + 1.5 kg ha-1 soil application after 21 days + 0.75 kg ha-1 as soil application + best dose of previous year.

Keywords: Mung bean, rhizobium, alluvial soil, morphophysiological parameters.
