The present investigation focused the pre-emergent impact of three concentrations (100, 200 and 300 ppm/kg soil) of technical grade of monocrotophos on Vigna mungo plants. The assessment of Monocrotophos stressed Vigna mungo plants inoculated with Rhizobium sp. plant growth suppression was analyzed normally and the Rhizobium treated plant growth and development of Vigna mungo was observed. The plant height, root height, total height, no. of leaf, no. of hairy roots, leaf length, lead width, shoot grifth, number. of nodules, dry biomass, legheamoglobin, and seed yield parameter were analyzed. When the pesticide dose was increase with the growth also decreased. The study suggests that the different strains of Rhizobium sp such as RS1, RS2 and RS3 was introduced and their growth and development was measured in periodically and yield of seed, dry biomass and legheamoglobin also recorded. The application of pesticide in the soil was reduced in the higher concentration from invitro experiments. | Effect of pesticide on the suppression on the growth and development of Vigna mungo treated with Rhizobium sp.
