Seed increase of the 1300 accessions from both the cultivated subspecies (coccineus and polyanthus) and the wild forms of Phaseolus coccineus is being carried out at 2 locations of Colombia. In Popayan (1700 m alt., 18 degrees Celsius mean temp., and 2000 mm annual rainfall), 12 plants of each ac...

Results obtained in expt at CIAT are analyzed 20 maize hybrids were planted in 4 replications for 2 seasons, in monoculture and in association with bean genotypes P566 and P589, types II and IV (bush and climbing). In monoculture, Tropical White Mix gave the more than yield in both seasons (7.26 ...
The different alternatives for disease control in cassava, reported as efficient and that could be taken into account when designing technological packages for cassava production, are summarized. These are cultu-ral control (crop rotation, planting on furrows, elimination of crop resi-dues, dista...
Calf records for a 30 year period (1965-1995) on purebred and crossbred N'dama and West African Shorthorn (WASH) cattle and their crosses with Santa Gertrudis or Red Poll were analyzed to determine factors affecting birth and weaning weights and to estimate genetic parameters. Male calves weighed...

The preoccupation of many conservation planners with the refinement of systematic assessment techniques has manifested an “implementation crisis” in conservation planning. This preoccupation has provided systematic assessments with well-tested tools (e.g., area selection algorithms) and principle...
