Adaptive performance of six maize (zea mays l1 composites on hill slopes of the chittagong hell tracts region

Abstract

The adaptive performance of six maize composites and a local check (Barnali) on hill slopes of the Agriculture Research Substation, Khagrachari, CHT’s under conventional cultivation were investigated in two seasons (1986-87). The composites Guiara 8045 and Across 8146 performed better on the 0 to 20% hill slopes of the CHT’s than the others in respect of kernel and stover yield, 1000- kernel weight and number of kernels/ear. La-maquina 7827 gave the lowest yield (1.57 t/ha). Across 8146 was the earliest (43 days) with an appreciable kernel yield (2.44 t/ha). While Barnali was late (51 days) giving a low yield (1.74 t/ha) and also having the least number of kernols/car.
