The field experiment was carried out at Research cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) to evaluate the effect of different crop establishment methods and weed management practices on chickpea in rice based cropping system during 2019-20 and 2020-21. The soil of the experiment field was clay in texture, neutral in reaction, low in organic carbon, low in nitrogen and low in phosphorus and high in potassium contents. The experiment was planned in split plot design with three replications, having three different crop establishment methods viz,. Zero seed drill (T1), Happy seed drill (T2) and Normal seed drill (soil preparation only by rotavator) (T3) in main plot, three weed management practices viz., W1: Chemical weed control, W2: Hand weeding twice and W3: Unweeded check control in sub plot respectively. Recommended dose of fertilizer used were 20:50:20:20 kg N:P2O5:K2O:S ha-1, respectively. The result of the experiment revealed that highest growth parameters, yield attributes, seed yield (Mean viz. 1654 kg ha-1) and stover yield (Mean viz. 2019 kg ha-1) of chickpea were obtained under the adoption of happy seed drill (T2) followed by normal seed drill (soil preparation only by rotavator) (T3) during both years of result including mean value. However zero seed drill was least effective in increasing the yield of chickpea during both years of experiment. Among weed management, hand weeding twice recorded the maximum seed yield (Mean viz. 1740 kg ha-1) and stover yield (Mean viz. 2223 kg ha-1) of chickpea as compare to unweeded control.
