Abstract

Potassium and ZINC are two essential elements for different crops such as CORN. CORN requirement to POTASSIUM and ZINC is relatively high. In order to study role of POTASSIUM and ZINC on grain production and growth parameters of grain CORN, a field experiment were conducted in Karaj Soil & Water Research Station with soil K and Zn available 163 and 0.66 mg kg-1, respectively. In this experiment, interaction of four levels of POTASSIUM (0, 25, 50 and 75 kg ha-1 K2O), two POTASSIUM sources (chloride and sulfate) and two levels of ZINC (0 and 10 mg kg-1 Zn as ZnSO4) were compared by factorial in completely randomized block design with three replications. All of agronomic operations carried out based on research recommendations.The results showed that Zn and K application caused significant increases at 1% levels(a=0.01) on grain yield and 5% levels (a=0.05) on the other plant parameters that measure, exception the protein content and percent of grain to wood stalk. The most effects of fertilizer treatments were on grain yield, the numbers and weight of grains in each stalk. Application of 50 kg ha-1 K2O as K2SO4 and 10 kg ha-1 Zn as ZINC sulphat at the same time (K2S1Zn1 treatment) caused grain yield, the number and weight of grains in each stalk increases from 6834 kg ha-1, 510 and 177 g per stalk in control to 9167 kg ha-1 633 and 219 g per stalk, respectively. In general, there was no significant difference between to POTASSIUM sources.
