تاثیر روش‌های مختلف خاک‌ورزی بر عملکرد نخود رقم هاشم در کرج

This study carried out in experimental field of University of Tehran in Karaj, as RCB design with four replications to evaluating the effects of different tillage methods on chickpea yield (Hashem cultivar) in 2012. Treatments were included three method of tillage; a) conventional tillage, b) minimum tillage, and c) zero tillage. The results demonstrated that the grain yield and harvest index of chickpea were the highest in minimum and conventional tillage system without statistically differences. While the chickpea in the zero tillage system has the lowest yield which possibly due to special shape and biology of seedling emergence, lack of organic matter and heavy texture of soil of the research farm that led to decrease of seedling emergence from soil surface. So, in which fields with heavy texture of soil and low organic matter, it would be better to use of minimum tillage system to increase the rat of yield because of moisture retention and the other benefits and also lower costs.
