Investigates the effects of improved surface drainage on the productivity of Vertisols in a wheat-and-chickpea cropping trial conducted in 1987 at ILCA;s Debre Zeit research site in the Ethiopian highlands. Chickpea plots were subjected to four irrigation treatments, viz, no irrigation, irrigatio...

Field studies were conducted between 1987-1989 at sites on Vertisols at different altitudes in Ethiopia to assess the effects of mixtures of clover undersowings on grain, straw yield and the total biomass production of several wheat varieties. Wheat varieties grown at the medium altitude location...
