Improving maize productivity in the savannas of West Africa will depend on improving soil fertility and ensuring the efficient use of inputs and the relevant maize varieties tolerant to low nitrogen (N) that have been developed for this region. Several cycles of full-sib family selection that com...

Growth and N uptake in pot-grown maize, beans, and cassava were evaluated under 2 levels of soil N at CIAT-Palmira (Colombia). The lower amount of the element reduced its uptake by the 3 species, resulting in lower tissue concn., especially in the leaves. Under low N, DM accumulation was also red...

Many types of analysis require rainfall data, which must often be generated to overcome limitations in the historical record. The ability to model outlying rainfall years satisfactorily is particularly important in risk studies. We describe a rainfall generator with this ability, based on a third...

In experiment 1 a duplicated 4 X 4 Latin square design was used in which 8 Finnish Ayrshire cows in mid-lactation were given 8 kg of oats and barley and grass/red clover silage ad libitum with or without (controls) commercial rapeseed meal (218 g/kg DM; RSM), crushed organic field pea (Pisum sati...
