Achieving sustainable food security in Nigeria is feasible through organic farming. However, unavailability and resource constraints hamper the adoption of agricultural inputs; hence the market offers opportunity for use of purchased organic inputs. In assessing the importance of the market, the ...

Monoculture of irrigated rice (Oryza sativa L.) in Latin America has led to serious weed problems and intensive herbicide use. Yield loss prediction enables the economic analysis of weed control, providing a basis for strategic use of herbicides and diversified weed management, but site differenc...

Commercial cassava production from true cassava seeds (TCS) appears to be a promising option for reducing or eliminating several of the production constraints associated with vegetative propagation. The most important contribution of TCS would be to reduce virus build-up in vegetative material an...

Nitrogen deficiency severely limits production of the bean maize association grown by small-scale farmers in upland Peru. Sixty-four bean Rhizobium isolates were evaluated for induction of a plant growth response in pots of soil from the area and 14 of the most promising strains of these were tes...
