Abstract
Field experiments were conducted under rain-fed conditions between 1986 and 1995 to investigate the effects of soil and water conservation treatments (tied ridges and planting methods) on the yield of an improved sorghum variety (ETS-2752) grown with and without N and P fertilizers on two major soils of Alemaya area, eastern Ethiopian highlands. The yield responded significantly (P ≤ 0.01) to the treatments both under fertilized and unfertilized conditions of the soils studied. However, the magnitude of the yield response and the relative efficiency of the tied ridges and planting methods varied with soil type, fertilization, and total rainfall and its distribution during the cropping season. Regardless of the type of tied ridge used, furrow planting, specifically, closed end tied ridge planting in furrows gave the highest yield in three of the four sets of experiments. Flat bed planting produced the lowest grain yields on all sets of experiments except under the unfertilized condition of Entisols in which open end planting on ridges produced the lowest sorghum yield. Within the tied ridges, closed end performed better than open end in all except the Vertisols without N and P fertilizers. Compared with
