The effect of managing hedgerow foliage for mulch and fodder in Leucaena leucocephala and Gliricidia sepium alley farming systems on maize grain yield and soil chemical characteristics was studied in on-station and on-farm experiments in southwestern Nigeria. Yields increased as the proportion of...

Six rumen cannulated sheep (26.1 (s.d. 2.24 kg live weight) given maize stover ad libitum were supplemented with either sunflower cake (SFC), decorticated cottonseed (CSC) or noug cakes (NGC) with or without crushed maize grain. The 6x6 Latin-square experiment studied the degradation properties o...

The effects of Leucaena leucocephala and L. pallida prunings and cattle manure on maize nutrient uptake and yield were investigated in a hedgerow inter-cropping trial in the Ethiopian highlands. Hedgerow inter-cropping (also called alley cropping) is an agroforestry system in which trees are grow...

Nutritionally enhanced beans (NEB) with more Fe and Zn than conventional beans (CB) and nutritionally enhanced maize (NEM) with more tryptophan and lysine than conventional maize (CM) were developed as part of a crop-biofortification strategy to improve human nutrition. Proxy measures were used t...

Los cruzamientos dialelos de 12 padres contrastantes en la toma y uso de fósforo se evaluaron en dos niveles de fósforo (4 y 15 ppm) usando un dise o experimental de alpha lattice con tres repeticiones. Se usó el dise o genético propuesto por Hallauer y Miranda. En bajo y alto fósforo se encontra...
