اثر آرایش کاشت، نیتروژن و مگافول بر عملکرد، اجزای عملکرد و پروتئین دانه نخود تحت شرایط دیم

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 ۲۰۱۷-۲۰۱۸. The planting pattern is in three levels of ۳۰×۱۱, ۴۵×۷.۴, and ۶۰×۵.۵ cm (۳۰ plants. m-۲) and the factor of use of fertilizers in five levels of non-consumption and consumption of ۵۰ and ۱۰۰ kg nitrogen and one and two liters of megafol per hectare. The results show that the highest seed yield is related to ۳۰×۱۱ and ۴۵×۷.۴ and the lowest is related to ۶۰×۵.۵ cm. Seed per plant and seed yield in application of ۱۰۰ and ۵۰ kg N ha-۱ has been higher than others. The highest and the lowest protein percentage of seeds is related to ۶۰×۵.۵ and ۳۰×۱۱ cm. ۱۰۰۰-seed weight in application of ۱۰۰ and ۵۰ kg N ha-۱ and ۲ 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 ۱۰۰ and ۵۰ kg N ha-۱, it seems that consumption of ۵۰ kg N ha-۱ and planting pattern of ۳۰×۱۱ is the most appropriate advice for planting of rainfed chickpea in Gonbad Kavous condition.
