اثر محلولپاشی و خاکپاشی عناصر آهن و روی بر پروتئین، روغن دانه و عملکرد دو رقم سویا

In order to investigation the effects of foliar and soil application of zinc and iron on protein percent, seed oil
and yield of two soybean cultivars, an experiment was conducted in factorial arrangement on completely
randomized block design in 2013 at Rasht Rice Institute of Iran. Results showed that significant differences
in all subjects of treats, cultivars and their interactions. Biological yield, seed yield and harvest index, the
interaction effects of Sahar cultivar with application treats had higher means, but oil percent and protein was
higher in interaction of Wiliams cultivar with treats. The intraction results of harvest index showed that
interaction of Sahar cultivar with zinc foliar application had highest mean and interaction results of
biological yield and seed yield showed that interaction of Sahar cultivar with iron foliar application had
highest mean. The interaction of zinc soil application with Wiliams cultivar had highest protein percent and
interaction of zinc foliar application with Wiliams cultivar had highest oil percent.
