In order to investigate the effect of planting pattern and nitrogen and megafol on grain yield, yield components and seed protein of chickpea (Cicer arietinum L.) under rainfed conditions, a factorial experiment was conducted in a randomized complete block design with three replications in Gonbad Kavous University farm during growth season of 2017-2018. The planting pattern was in three levels of 30×11, 45×7.4 and 60×5.5 cm (30 plants. m-2) and the factor of use of fertilizers in five levels of non-consumption and consumption of 50 and 100 kg nitrogen and one and two liters of megafol per hectare. The results showed that the highest seed yield was related to 30×11 and 45×7.4 and the lowest was related to 60×5.5 cm. Seed per plant and seed yield in application of 100 and 50 kg N ha-1 was higher than others. The highest and the lowest protein percentage of seeds was related to 60×5.5 and 30×11 cm. 1000-seed weight in application of 100 and 50 kg N ha-1 and 2 liters of megafol was more than other treatments. The harvest index in application of fertilizer was the maximum and in treatment of non-application of fertilizer was the minimum. In addition, because of more effect of nitrogen on seed yield compared to megafol and non-significant differences between consumption of 100 and 50 kg N ha-1, it seems that consumption of 50 kg N ha-1 and planting pattern of 30×11 is the most appropriate advice for planting of rainfed chickpea in Gonbad Kavous condition.
