Effect of Planting Pattern and Nitrogen and Megafol on Yield, Yield Components, and Grain Protein of Chickpea under Rainfed Conditions

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 has been conducted in a randomized complete block design with three replications in Gonbad Kavous University farm during growth season of 2017-2018. 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.
