Abstract
Tillage operations and provision of plant nutrients are one of the necessary strategies for increasing the yield of winter rain fed chickpea crops. Due to lack of information on seedbed preparation and the effects of nitrogen fertilizers on the chickpea properties, this study experiment was conducted to determine the effects of applying nitrogen fertilizers and those of tillage on the quantitative and qualitative features of rain fed chickpea in the province of Lorestan during the cropping year 2012-2013. We employed the split plot design in the format of randomized complete block design with three replications. The main plots included (burning plant residue +plowing with a moldboard plow + two disking operations),(plowing with a chisel plow+ two disking operations(three disking operations),(zero tillage). The sub-plots included the various rates of applied nitrogen fertilizers:(Zero),(46), (69),and(92 kilograms per hectare). Results of variance analysis showed thatthere were very significant differences between various types of tillage and different rates of nitrogen application with respect to the features of biological yield, number of seeds per plant, number of single-seeded pods, number of double-seeded pods, number of fertile pods, percentage of seed protein, and seed yield. The maximum seed yield(1415 kg/ha) belonged to the treatment (burning plant residue+ plowing + two disking operations), and the maximum seed yield of nitrogen treatment (1223.3 kg/ha) was observed in the treatment of applying the highest rateof nitrogen (N4 ). Furthermore, the mutual effects of tillage and nitrogen fertilizer application were significant on seed yield, and the maximum seed yield (1553.3 kg/ha) was obtained in theT1N4 treatment
