Evaluation of yield and micronutrients uptake in Pisum sativum L. cv. wando under iron and silicon interaction

چکیده

 To assesse the iron and silicon effects on the yield and physiological characteristics of green pea, Wando cultivar by ASGrow Corporation was used in three levels of iron chelate (0.05, 0.1 and 0.3 gr per l-1) and silicon (0, 14 and 28 mg per l-1), as a factorial experimental in completely randomized design with three replications. In this experiment, characterisics such as fresh and dry weight of grain, the number of grain per pod, concentration of Fe, Cu, Mn, Zn and Si in leaf and grain were measured. Results showed that the interaction of Fe and Si was significant at p<0.01 on grain fresh and dry wigeht, concentratin of leaf and grain Fe, leaf Mn, leaf and grain Zn and leaf Si and the application of Fe and Si was significant separately, on other traits such as number of grain per pod, concentration of leaf and grain Cu, Mn and Si in grain.  The Mean squares showed that the application of Fe and Si significantly increased fresh and dry grain weight and Si laef concetration and decreased the concentratin of leaf and grain Fe and Mn as well as grain Mn.  The enhancement of Fe and Si application separately decreased the concentration of Mn, Cu and zinc leaf and grains, but the Si concentration of leaf and grain were increased by Si application. The concentration of Fe, Mn, Cu and Zn were decreased in leaf and grain because of antagonistic effects. It can be concluded that Si reduces the harmfull effects of high levels of iron toxicity and the application of 0.1 g/l and 25 mg/l can be recommended as the best treatments.
