| Abstract | ||
| Afield experiment was conducted to study effect of foliar nutrition of potassium and chalated iron in vegetative growth of corn( Zea mays L.) under drip irrigation system.Random Complet Block Design was used in factor experiment with three replications. Spraying four concentrations of potassium(0,1000,2000,3000) mg.l-¹ and four concentrations of chelated Iron (0,50,100,200)mg.l-¹. The result showed that the suitable K- foliar nutrition treatment was 3000mg.l-¹ which caused significant differences in plant height , number of leaves,stem dimeter, leave area and dry matter of green growth .So using Fe-foliar nutrition treatment was 50mg.l-¹ caused significant differences in plant height and number of leaves and100mg.l-¹ caused significant differences in leaves area,stem dimeter and dry matter of green growth, While 200mg.l-¹ caused low of all traits because negative effect of iron ،Interaction between potassium and iron K3000 * Fe100 was significant effect in stem dimeter, leave area and dry matter of and K decresed high level of Fe monitor form. | ||
