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...

Sequential cropping of Vertisols in the Ethiopian highlands using a broadbed-and-furrow system
In the Ethiopian highlands, where integrated crop and livestock production takes place, the inadequate supply, in both quantity and quality of feeds during the year is a major constraint. Native pastures and crop residues are the major feed sources, but their quality is often poor. Integration of...

Effects of cropping system, seed bed management and fertility interactions on biomass of crops grown on a Vertisol in the central highlands of Ethiopia
Mixed crop-lvestock production system is the major agricultural production system in Ethiopia with a wide array of Development challenges and opportunities. One of the key challenge in improving the agricultural productivity of the system is feed scarcity and undernutrition. The major basal feed ...

An on farm tiral, in which a wheat-clover mixed cropping treatment was compared to an unfertilized (control) and N-fertilized (23 kg N ha-1) pure wheat treatments, was conducted at Ginchi (2200 metres above sea level (masl) and Deneba (2600 masl) in the Ethiopian highlands. The total crop residue...

Thirty-six crossbred cows were used in a 2 X 2 factorial arrangement in a randomized block design to evaluate forages from two cropping systems (1 and 2) and feeding levels (ad libitum, (Level1)) or 80 percent of ad libitum (Level 2) on milk yield, live weight, and reproductive performance. Crops...

Comparative yield and nutritive value of forages from two cereal-legume based cropping systems. 2. Milk production and reproductive performance of crossbred dairy cows
Poor drainage of Vertisols in the Ethiopian mid-altitude highlands limits farming operations and cropping in the early rainy season. Thus, traditional crops are grown late in the season on the residual moisture in the dry season when waterlogging is less of a problem. Consequently performance of ...

The effects of two cropping systems (1 and 2) on grain and fodder yields and nutritive quality of the fodder were studied in a randomized complete block desgin experiment over a period of two cropping years. Crops and crop combinations in system 1 were oat-vetch, wheat-trifolium, teff straw, and ...

Discusses the traditional and potential cropping systems for the highlands of Ethiopia. Traditional Vertisol management methods of these soils fail to overcome waterlogging problems, and therefore croping practices vary from place to place to suit the length of time left after the water is natura...

This paper ilustrates the principle determining cropping systems for Vertisols by reviewing work in the highlands of Ethiopia. The types of cropping systems that can be applicable in the different Vertisol environments are briefly described. These cropping systems include single cropping; multipl...
