Thirty bean lots, belonging to 28 farmers, were monitored in the municipalities of San Gil and Villanueva. Short interviews were conducted with the farmers to determine why they use certain types of furrows and their perception of erosion processes. Lots were divided into 3 groups: furrows down t...

A study was conducted in the Shoa plateau of the north-western Ethiopian highlands to investigate the patterns of dry matter production, the effect of season of establishment, and the best time of harvest for 8 native African and 3 exotic clovers. The native clovers gave higher dry matter yields ...

Three varieties in one cassava trial and 5 in another were planted in a sytematic density experiment, which showed that optimum plant density for root yield changes with plant age. Some varieties showed a pronounced optimum plant population whereas others showed a flat-topped response curve. Redu...

Tropical agroecosystems constitute diversified systems with crops arranged in polycultural patterns. Weeds are important components of these systems and condition insect diversity and stability. In an attempt to gather experimental evidence as a basis for tropical pest management strategies, 9 fi...

The slow progress made in the search for var. with higher levels of drought tolerance is partially due to the inefficient management of nurseries. At CIAT, screening for tolerance has evolved at almost all stages, from planning through the analysis of final results. This report describes several ...
