Tyr-67 and Asn-52 are among the conserved residues in the amino acid sequence of eukaryotic cytochromes c. These residues, together with Thr-78 are hydrogen bonded to a buried water molecule, (Wat-l66), which is also a conserved structural feature in all naturally occuring eukaryotic cytochromes ...

Water relations of Panicum maximum under Acacia tortilis and Digitaria macroblephara in the open, were studied under field conditions at the National Range Research Station, Kiboko Kenya and under controlled environmental conditions at Texas A&M, University. Mean soil water potentials at 10 cm, 3...

Burning of vegetation is common in most Kenya rangelands and has been done since time immemorial. However, little is known of the effects of burning on soil and plant water status. To investigate these effects, measurement of soil water potential, atmospheric variables, and xylem tension, transpi...

The study aims to estimate the livestock water productivity (LWP) and to examine the effect of grazing area closure and feeding strategies on LWP at farm household level under wealth and intervention categories at Lencha Dima watershed. Results are based on survey of 120 sample households and foc...

Investigations were carried out on the effects of water and food deprivation on the milk yield, body weight, blood composition and urine volume of lactating Nubian goats. The animals survived 4 days of deprivation of either food or both food and water, but these treatments resulted in about 10 pe...

Mali is one of the least developed countries with an economy that relies heavily on rainfed cereal production. Rural communities are faced with extreme poverty as a result of unpredictable rainfall pattern and lack of appropriate agricultural intervention practices. Most agronomic practices in su...

Conservation agriculture (CA) is a promising technology for controlling soil degradation, mitigating drought, increasing crop yield and reducing production costs. We hypothesized that adopting CA system would improve system productivity and efficiency, hence resulting in higher profits. To test t...

Smallholder irrigation to improve food security in the dry season as well as economic and demographic growth within Ethiopia is developing rapidly. However, the long term sustainability of increased irrigated production, together with degradation of soils (and associated water bodies) may be irre...

Communication and knowledge sharing among stakeholders working in rainwater management has a paramount importance to create shared understanding and to narrow the gap between research and action. Even though various rainwater management initiatives have been undertaken in Ethiopia in the last thi...
