This study examined the effect of lablab hay supplementation of crossbred cows fed forages from cereal+forage legume intercropping (maize–lablab (ML) stover or oats–vetch (OV) hay) basal diets on feed intake, apparent digestibility, milk yield and milk composition of crossbred cows. Forty eight m...
This study examined the interaction of high energy substrates (ES: crushed maize grain (MG) and wheat bran (WB) with forage legumes (FLs), such as Lablab purpureus hay, sun dried leaves of Sesbania sesban and tagasaste (Chamaecytisus palmensis), on ruminal microbial activity (indexed by the degra...
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...
A greenhouse experiment was conducted to determine the critical deficiency levels of potassium (K) in the subhumid zone soils for predicting response of a mixture of Andropogon gayanus and Stylosanthes hamata cVerano to K application. Twenty coarse textured soils, having loamy sand to sandy loam ...
The fast depletion of available potassium (K) in soils of the subhumid zone (SHZ) of Nigeria has become a problem for the formulation of fertilizer recommendations, especially in the grass/legume mixtures of the fodder bank system. Five different K fertilizer recommendation models viz. Control, C...
Although the majority of soils in Africa are P deficient, the high cost of conventional water-soluble P fertilizers limits their use by resource-poor farmers. Rockphosphates are a low-cost alternative. The effect of Egyptian rockphosphate (ERP) from two sources, applied at 50 kg P ha-1, on annual...
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...
Poor drainage of Vertisols and nitrogen (N) and phosphorus (P) deficiencies are some if the major constraints to food and feed production in the Ethiopian highlands. The effects of soil drainage and P supply on N fixation by annual trifolium species and their residual value to succeeding crops wa...
