A Review on: Effect of Tie Ridging on Crop Productivity in Dry Land Agro-Ecosystems of Ethiopia

Hailemariam Abrha Demoz


This review focuses on literatures made on in-situ moisture conservation using tied ridges on crop productivities such as sorghum, maizeand cotton in different parts of Ethiopia under rain-fed conditions. The magnitude of theyield response and the relative efficiency of the tied ridges and planting methods variedwith soil type, fertilization, and total rainfall and its distribution. Closedend tied ridge planting in furrows(CPF) gave the highest yield.Flatbed planting produced the lowest grain yields on all sets of experiments.Within the tied ridges, closed end performed betterthan open end.In sorghum compared withthe traditional (flatbed) planting method, the highest yield increment of 1361 kg/ha(34.5%) due to tied ridges was obtained on the Entisols with NP followed by 1255kg/ha (48.5%) on black clay soils (Vertisols) under fertilized condition.Highest maize yield 1616 kg/ha was achieved with closed end tied ridge planting in furrows type of water conservation technique, but the FPB (Flatbed planting) was 844.8kg/ha. In Humbo, south region of Ethiopia, open and tied ridge on Cotton variety ‘Sele’wasused’ revealed that, there was a significant (p<1%) seed cotton yield record in open ridge planting method followed by tied ridge planting 1619 kg/ha butflatbed planting method gave significantly the lowest seed cotton yield 1273 kg/ha.
