Although this document is intended to report research on Vertisols, livestock do not respect this boundary as they graze communal land. Hence a general situation of the available feed resources in the highlands is also highlighted which is followed by specific efforts of collaborative partners of...

The experience of ICRISAT with the use of Vertisols in semi-arid India indicates that the key to drastically improved productivity of Vertisols is the effective control of surface soil water which then enables rational use of the land for food and feed production. ILCA, therefore, developed and t...

Understanding the problems of grazing land in vertisol areas and seeking long-lasting solutions is the central point where mixed crop livestock is the second stay for the majority of the population. In order to understand this, the current study was conducted at two sites, one with 0-4% slope and...

This chapter summarises the experience of a research project for developing and disseminating technologies for better management of Vertisols for improving productivity. Topics of discussion include Vertisol technology Development and testing in Ethiopia; the adoption pathways for the BBM package...

The productivity of the Vertisols in the Ethiopian highlands could be raised by facilitating the removal of excess water from the field in the main rainy season. This could be accomplished by the introduction of an animal powered broadbed maker (BBM) which shapes the soil into broadbeds and furro...

At the Debre Zeit Station Cereals (wheat and maize) and forage legumes (lablab, cowpea, vetch and clover) were grown as sole crops and as cereal/forage combinations on the broadbeds separated by drainage furrows (BBF). This is an improved land management system, developed by ILCA in collaboration...

Examines the effects of broadbed and furrow land management systems and supplementary irrigation on the productivity of sequentially planted wheat and chickpea on Vertisols wheat was grown during the main rainy season on boradbeds and furrows made with an animal drawn implement to drain off the e...

The literature on technology adoption distinguishes between diffusion (generally viewed as a dynamic process) and adoption (usually seen as static and specific to a point in time). Consistent with this, empirical studies on agricultural technology adoption generally divide a population into adopt...

Land-use intensification in the East-African highland zone is required for meeting food and feed demands from the rising human and animal populations. A single crop of wheat has been a traditional practice for the 8 Mha of Vertisols in the Ethiopian highlands with both grain and residues finding ...
