Abstract

Field trial was conducted at research farm of weed science research center, Parbhani, in split plot design with an objective to study the effect of herbicides on biochemical activities and nodulation in chickpea (maize-chickpea cropping system) during 2012–2013.The soil of experimental plot was black cotton soil with medium fertility and pH 7.9, EC 0.32 dsm−1, and OC 0.57%. The treatments comprised of four weed control measures (weedy check, mechanical weeding, weed free, and pendimethalin 1.0 kg ha−1). The soil samples were collected from rhizospheric soil from each plot at 30, 50 DAS and at harvest of crop and were analyzed for soil microbial biomass carbon and basal soil respiration and number of nodules and nodule dry matter. The results revealed that there were nonsignificant variations observed due to various treatments in affecting soil physicochemical properties of soil at various crop growth stages. Highest microbial population, microbial biomass carbon, and basal soil respiration were recorded in mechanical weeding, whereas lower activities were recorded in pendimethalin applied plots at 1.0 kg ha−1 at 30 DAS. These values were enhanced at harvest. Application of pendimethalin1.0 kg ha−1 did not influence nodal count and nodal dry matter significantly.
