Tarawali, G.Mohamed-Saleem, M.A.Kaufmann, Ralph R. von[Main-d'oeuvre requise pour la culture du mais sur des jacheres et sur des sols precedemment voues a Stylosanthes - zone subhumide du Nigeria]Main-d'oeuvre requise pour la culture du mais sur des jacheres et sur des sols precedemment voues a Stylosanthes - zone subhumide du Nigeria

Studies of potassium (K) fixation in the soil were conducted by evaluating the effect of applied K on the extractability of K with time. A series of five K-sorption treatment solutions, 0.11, 0.22, 0.45, 0.90, and 1.80 cmol/kg were prepared and applied as potassium chloride (KC1) to three sets of...

The browse shrub Gliricidia sepium, introduced into the subhumid zone of Nigeria to serve as a supplementary-forage source for ruminant during the dry season, has the undesirable characteristic of shedding its leaves during its flowering phase which coincides with the early dry season. This repor...

Studies the effect of ridge height on sorghum production and the benefits associated with ridging including increase in yields of grain and residue and root density.

The dry matter yield, nutritive value and persistence of three legume species (Stylosanthes hamata Taub., S. capitata Vog. and Centrosema pascuorum Mart. ex. Benth.) cut at different frequencies during the growing season or only once at the end of the growing season were compared. The shorter cut...


Tarawali, G.Mohamed-Saleem, M.A.Chionuma, P.C.[The effect of frequency of defoliation on the productivity of selected forage legumes (Stylosanthes hamata, Stylosanthes capitata and Centrosema pascuorum) in the sub-humid zone of Nigeria]The effect of frequency of defoliation on the productivity of selected forage legumes (Stylosanthes hamata, Stylosanthes capitata and Centrosema pascuorum) in the sub-humid zone of Nigeria
Tarawali, G.Mohamed-Saleem, M.A.Kaufmann, Ralph R. von[Legume-based cropping. A possible remedy to land tenure constraint to ruminant production in the subhumid zone of central Nigeria]Legume-based cropping. A possible remedy to land tenure constraint to ruminant production in the subhumid zone of central Nigeria

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 ...


Tening, A.S.Tarawali, G.Omueti, J.A.I.[Critical potassium deficiency levels for a grass legume pasture grown on soils of the subhumid zone of Nigeria]Critical potassium deficiency levels for a grass legume pasture grown on soils of the subhumid zone of Nigeria

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...

Over a grazing period of about 14 weeks, comparisons were made between pasture improved with Stylosanthes hamata and that based on natural grassland. The grazing densities ranged from 2.11 to 4.23 TLU/ha (Tropical Livestock Unit = 250 kg liveweight). Both pastures were grazed in the previous wet ...

Twenty surface soils (0 to 15 cm), selected to represent a wide range of available potassium (K) status and three different land-use systems (fodder bank, continously fertilized cropped land and fallow land) across the subhumid zone of Nigeria, were used for the investigation. Laboratory and gree...
