SummaryEffects of plant density ranging from 44444 to 133333 plants/ha and tillage practices (planting in flat beds (control), in the furrows of open ridges, on the top of open ridges, in the furrows of tie-ridges and on the top of tie-ridges) on growth and grain yield of sorghum were investigated at Kobo, a typical semi-arid area in Ethiopia, during 1980, 1981 and 1982 cropping seasons. Plant growth was limited in the flat beds because they were likely to be deficient in soil moisture and sometimes in the tie-ridging treatments, due to waterlogging. However, planting on the top of tie-ridges produced 1·6, 0·4 and 1·8 t/ha more yield than in the flat beds, the method commonly practised by the Kobo farmers, during 1980, 1981 and 1982 respectively. In all seasons, the effect of plant density did not show marked differences. The plants rather adjusted their reproductive growth and development to the seasonal rainfall and presumably to the available soil moisture at the grain-filling periods. It was concluded that the highest plant density did not reach the optimum for the area. Planting sorghum on the top of tie-ridges is recommended.

This study focuses on the outstanding issues of the serious lack of water resources in semi-arid area of western Liaoning province. Traditional cropping patterns as contrast, studied the effect of unary or binary coverage of three micro-catchment patterns, which were ridge film mulching and furrow seeding (T1), groove ridge mulch film (T2), ridge ditch straw mulching cultivation (T3). Compared with the traditional pattern, micro-catchment patterns have obvious water gathering effect. This experiment, T2 of the best water conservation and water harvesting, compared to the traditional pattern, the average soil moisture content improve 2.38% in the growth period. Followed by T3, improves 1.71%. The third was Tr1, improve 1.43%. Micro-catchment can be avoided the drought of soil deeply by covering mulching film. 63mm precipitation can effectively improve 0-80cm soil moisture. While gullies covering film or direct planting cultivation can significantly increase soil temperature. Although the straw covering did not have the role to increase the soil temperature, the soil temperature was more close to the traditional cropping pattern. Compared with the traditional pattern, the average soil temperature of T2 increased by 2.42°C, T1 increased 1.99°C, T3 reduced 0.21°C.
