Effects of Relationships Between Leaf Area Value Removed and Cob Characteristics in Corn Plants

Abstract

The corn plant completes its development in a very short time, the major organs contributing to the yield of the corn plant are the roots and leaves. The aim of this study was to examine the leaf areas, ear grain weights, cob weights, ear row numbers, and grain numbers of ear row by applying four different leaf removal treatments to D. 6761, P. 1921, P. 2105 and Klumet hybrid corn varieties and to determine the correlation relationship between the examined traits. It was observed that the leaf areas increased from the top tassel to the leaves above the ear, but the three leaves below the top tassel contributed more to the ear grain yield than the three leaves above the ear. It was recorded that all leaves above the ear contribute to the yield, and that there is a linear relationship between ear grain yield and leaf area and cob diameter. The effect of leaf removal practices on the number of ear rows and the number of grains per row is thought to be less effective than genetic factors.
