Abstract: A field experiment was conducted at the Agronomy Research Farm of IGKV, Raipur, during the Rabi season of 2010-11 and 2011-12. Incorporation of tillage and weed management practices considerably improved the yield of chickpea interms of N-uptake, number of nodules per plant and microbial activities of rice rhizosphere. Results indicated that, among the tillage management practices, higher N uptake, number of nodules and microbial activities were obtained with CT which was followed by MT and ZT. Among the various weed management practices, N-uptake and number of nodules were maximum under one HW at 20 DAS, followed by the treatments of POE application of imazethapyr @ 90 g ha-1 and POE imazethapyr @ 80 g ha-1, respectively. Whereas, microbial population, basal soil respiration and dehydrogenase enzyme activity of experimental field was significantly higher under weedy check plot, followed by one HW at 20 DAS and POE application of imazethapyr @ 90 g ha-1 during both the years.
