Study of effects of sowing date, row spacing and zinc and nitrogen fertilizers on rainfed chickpea in Gonbad

In order to evaluate the effect of sowing date, row spacing, foliar application of nitrogen and Zinc on yield and yield components of chickpea cv. Arman, a factorial experiment was carried arranged in an RCBD with three replications under rain-fed condition at the agricultural research station of Gonbad Treatments were combination of four factors, i.e. sowing dates (Nov 6th, Dec 6th and Dec 26th), row spacing (24 and 36 centimeters), two nitrogen foliar application (without application and spraying urea at 5/1000) and zinc Levels (0 and 30 kg/ha of zinc sulphate). In this experiment, grain yield, pods per plant, seeds per pod, one-thousand seed weight were counted or calculated. The results revealed the positive effect of foliar application of nitrogen,and zinc sulphate on some phenotypic traits, seed yield and yield components of chickpea. Zinc sulphate significantly increased seed yield (1913 kg ha-1) compared to without zinc sulphate treatment (1853 kg ha-1). In addition, nitrogen foliar application significantly affected plant height and seeds per pod. Number of seeds per pod with nitrogen foliar application (1.79 seeds) was significantly higher than that of no foliar application (1.46 seeds).
