Yield performance and agronomic characteristics of several candidate hybrid maize varieties on uncultivated land

Abstract

Corn is currently a strategic and dominant national commodity used as raw material for animal feed. The increase in productivity was made possible by the continued assembly of hybrid corn which has a higher production per hectare with a wide or site-specific adaptation rate. Due to the wide utilization of maize, the main objective of all commercial maize breeding programs is to obtain new inbred and hybrids which will outperform the hybrids mainly on grain yield characteristics. This research was conducted in Bone Regency to know the yield potential of several hybrid maize on uncultivated land, using a randomized block design, 4 replications, a plot area of 3 x 5 m, and spacing of 70 x 20 cm. The material used consisted of 4 hybrids and 2 comparison varieties. The results showed that the hybrid G1603 (11.61 t/ha) showed the highest grain yield and was not significantly different from the comparison varieties. This result was supported by the character of the number of rows of seeds per ear, the length of the ear, and the diameter. These characteristics need to be considered to get hybrid corn with a high grain yield.
