A field trial was carried out in CIAT-Quilichao (Colombia) to determine seed yield heritability, wt. of 100 seeds and days to maturity, in soils with high and low levels of fertilization. Plots were fertilized with 600 and 1800 kg of compost (15-15-15)/ha. The F2 and F3 generations of 22 single c...

We established hedges/barriers of calliandra (Calliandra calothyrsus Meissner), leucaena (Leucaena trichandra (Zucc.) Urban)) and napier grass (Pennisetum purpureum chumach) and combination hedges of either calliandra or leucaena with napier grass on slopes exceeding 5% to study the effect of veg...

Reports on the first four-year phase of a study of the long term effects on soil fertility and crop production of continuous cultivation (without trees), continuous alley cropping, and a rotation of alley cropping and fallow (with livestock) within Leucaena (Leucaena leucocephala (Lam) de Wit) al...

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...

There exists a considerable knowledge gap about the effect of biochemical quality of organic inputs and their combination with inorganic N on abundance and community composition of ammonia-oxidizing archaea (AOA) and bacteria (AOB). Here, we investigated in a Humic Nitisol of 10-year old field ex...

Crop production in sub-Sahara Africa is constrained by low soil phosphorus (P) content. A study was conducted in western Kenya to explore alternative P inputs and ways of optimizing their effectiveness and profitability. A field experiment established in 2007 studied the effects of Minjingu phosp...
