Nutrient management for cassava-based cropping systems in Northern Vietnam
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/81972
Abstract
Five soil types on which cassava is being planted were investigated. Almost all these soils are degraded in terms of soil properties, especially with respect to soil fertility. Cassava is traditionally planted without fertilizer application and soil conservation measures, resulting in a negative nutrient balance.
In experiments on the…

Abstract
Research in bean economics includes production, marketing and consumption, and policy studies. Production research focuses on 2 mutually reinforcing themes: (1) assessment of the spread of new var. recently released to farmers by national programs; and (2) assessment of farmers' current production systems and problems. Consumption and marketing of beans remain important research topics because most beans…

Abstract
During 1984 several types of interspecific crosses between Phaseolus vulgaris and P. coccineus, generated in the collaborative project with the U. of Gembloux, Belgium, were tested to evaluate their yield potential. Significant differences were observed between the crosses tested and among sister lines for traits such as yield, disease resistance, vigor, plant architecture,…
