Two projects on alley cropping research and development have been implemented in the Forest zone of Cameroon (FZC) since 1988. Their goal was to identify the main agricultural constraints in the FZC and to introduce alley cropping in the farming systems to improve soil fertility and crop yields. ...

This study was conducted at Ginchi watershed in Oromia Regional State, Ethiopia to evaluate the physical, chemical and microbiological quality of livestock drinking waters during dry, short rain and wet seasons. Purposive sampling technique was used to obtain samples. Data were collected and anal...

Two experiments evaluated variations in feed value among Calliandra calothyrsus provenances. In Experiment 1, edible forage production of four provenances were evaluated at Ibadan, southwestern Nigeria over a 2-year period in three seasons: main-wet (April-August), minor-wet (September-November) ...

Soil moisture depletion during dry seasons by planted hedgerows to lower levels than under natural fallow, would reduce drainage and nutrient losses in the following rainy season when food crops are grown. The volumetric water content of the 0–150 cm soil profile was measured under planted hedger...

A survey was conducted in Ginchi watershed area in Dandi district of Oromia Regional State, central Ethiopia. The objective of the study was to assess livestock production system, productive and reproductive performance of animals and to identify constraints to livestock production. Cross-section...
