Soil fertility decline is a major constraint to bean (Phaseolus vulgaris L.) and maize (Zea mays) production in the Central Highlands of Burundi. Nutrient sources, specifically fertilizers, are paramount to increasing the production in the regions. Hence, improving fertilizer use efficiency is co...

Nitrogen is the nutrient with greatest influence on yield and cost production of rice; it is then necesary to look for its most efficient use. Three field experiment were carried out to determine the agornomic efficiency of four urea forms (prilled, forestry grade, supergranules and sulfur-coated...

Commercialization of sweetpotato vines is persistent if multipliers show evidence of superiority of their vines. This study aimed at evaluating the effects of net tunnel source and of pathogen tested planting material compared to “apparently” healthy vines on yield and health status at three defi...

In rainfed crop production, root zone plant-available water holding capacity (RZ-PAWHC) of the soil has a large influence on crop growth and the yield response to management inputs such as improved seeds and fertilisers. However, data are lacking for this parameter in sub-Saharan Africa (SSA). Th...
