Effect of Ridge Spacing on Wheat Yield in Areas with Short Growing Periods.
1989
Wolde Amlak Araya
A ridge-spacing experiment was conducted for 5 year's 11987-1?83) at Mekele and Quiha on an improved variety of wheat to determine the effect of different spacing's on soil moisture grain and above-ground biomass yields. Spacing's of 20 cm 40 cm and 80 cm between tied ridges were used. The flat control was included for comparison. There was highly significant difference between ridge spacing's. The 80-cm spacing gave the highest grain yield and the best soil moisture values on the black soil at Mekele. The 40-cm spacing gave the highest grain yield and soil moisture on the red soil of Quiha. The above-ground biomass was greatest for 40-cm spacing at both locations.
