اثر محلول پاشی متانول و آهن بر رشد و عملکرد لوبیا در شهرستان رودسر

In order to study the effect of methanol and iron foliar on growth and yield of bean a factorial experiment with the base design of random is complete block design with three replications was conducted in roudsar city, 2013. Amounts of methanol with 4 levels(0, 10, 20 and 30 v/v) factorialzed with amounts of Iron with 4 levels(0, 2, 4 and 6 g/lit). Methanol and Iron has bean done foliar 2 times with 10 days gap during the growing season. And following charactristics were Meausred: plant height, 100 seed weight, dry pod yield, Biological yield, harvest index. The analysis of variance showed methanol foliar was significant difference between plant height, 100 seed weight, dry seed yield Biological yield, harvest index.And iron foliar was significant difference between plant height, 100 seed weight. The analysis of variance indicated that foliar of methanol had significant effects on dry seed yield, 100 seed weight, plant height, Biological yield and harvest index. also Iron foliar had significant effects on 100 seed weight and plant height. The interaction of methanol and Iron amounts on dry seed yield were significant. The comparison of means indicated that by increasing the amounts of methanol to 20( V/V) of more evaluated characteristic were affected. The highest dry seed yield( 928.3 kg/ha) was obtained while it has been sprayed by 20 (V/V) of methanol within 6 (g/lit) of Iron.
