About this title

Synopsis

The obtained data indicated that ear length and diameter, numbers of rows/ear and kernels/row and 100-kernel weight were increased significantly by decreasing plant density from 35 000 to 17 500 plants/acre. On the other hand, increasing maize plant density from 17 500 to 35 000 plants/acre by decreasing distance between hills from 40 to 20 cm apart increased significantly grain and stover yields/acre. Harvest index was decreased from 22.25 to 21.00% in the 1st season and from 22.14 to 20.04% in the 2nd season by widening distance between maize plants from 20 to 40 cm apart, respectively.Leaf area index was correlated positively and significantly with stover yield/acre in the two growing seasons. Positive but insignificant correlation coefficients were found between leaf area index and each of grain yield/acre and harvest index in the two growing seasons. While, Leaf area index was correlated negatively and significantly with each of ear weight, length and diameter and number of kernels/row in both seasons and with 100-kenel weight in the 2nd season.
