The important foods like black gram are very essential protein source for Indian population. The production of black gram is diminishing due to the infertile condition of Indian soil by the prolonged agricultural practices with chemical fertilizers. The present study is concerned with effective and alternative agricultural practices to chemical fertilizers on black gram production. The effective microorganism (EM) technology is used to evaluate the efficacy of beneficial microbes present in the EM solution against the black gram plant. The plants treated with EM showed good growth and yield also very much increased when compared with chemical fertilizers. The EM with vermicompost treatment increased the yield of black gram. The microbial population also counted in control and EM treated soils. The observation revealed that the EM treatment increased the microbial population. The present study suggests that the increased microbial population may be responsible for the increased growth and yield of black gram.
