The planting pattern is 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 show that the highest seed yield is related to 30×11 and 45×7.4 and the lowest is related to 60×5.5 cm. Seed per plant and seed yield in application of 100 and 50 kg N ha-1 has been higher than others. The highest and the lowest protein percentage of seeds is 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 has been more than other treatments. The harvest index in application of fertilizer is the maximum and in treatment of non-application of fertilizer is 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. %U https://jci.ut.ac.ir/article_81713_99056b0e1a09ad381377d4af562f8ad6.pdf
