Effect of iron soil and spray applied on some qualify characteristics of peanut (Arachis hypogaea L.) plants in a calcareous soil

In order to study the effect of foliar and soil applications of Fe-EDDHA on some qualify characteristics of peanut plants (variety NC2), two experiments were laid out separately in a Randomized Complete Block Design (RCBD) with three replications under field condition in Kiashahr harbor, Guilan province. In each experiment four levels of Fe-EDDHA were applied by one method (Foliar and Soil applications). In foliar application method, 0, 1, 2, 3 and 4 gr/lit Fe-EDDHA were sprayed on leaves at the beginning of branching as well as at the flowering period while for soil application method, 0, 5, 10, 15 and 20 kg/ha of Fe-EDDHA were applied at the time of sowing. The results showed that kernel oil in both methods of iron application decreased notably whereas kernel protein and also essential minerals such as active iron, total iron, N, P, K, Ca and Mg enhanced significantly. In both methods of iron application, higher doses of iron applications (4 gr/lit and 20 kg/ha of Fe-EDDHA) had significant positive effects on amount of essential elements. Altogether, iron soil-applied minerals had more effects compared to to iron foliar-application.
