Effect of Sulphur and Zinc on Growth and Yield of Peanut (Arachis hypogaea L.)

Peanut are one of the paired plants of oilseed and protein seed oil is a rich source. In order to evaluate effects sulphur and zinc on growth characteristics and yield of peanuts، a experiment was conducted in Bandar Kiashahr، Guilan province، Iran in 2008. The experiment laid out in a factorial arrangement with two factors sulphur (0، 40، 80، 120 kg ha) and zinc chelate on (0، 0. 5، 1 and 1. 5 g per lit) in a completely randomized complete block design with three replications. Results showed that amounts of sulphur and zinc significant effects were on Peanut plant traits، as pod yield، seed yield and oil content. The mean comparison of the properties studied showed that rate of 120 kg. h-1 sulphur was better than other treatments. Also had better efficacy between treatments of zinc chelate on treatment to 1. 5gr per lit. Also، the interaction of the sulphur and zinc had the most increase on these parameters.
