Simulation models have the potential of greatly enhancing decision-making by farmers and researchers in Nigeria. These models however, need to be adapted before use. This study was conducted to test the phenology module of CERES-Maize model version 3.5 under varying N rates as a step toward adapt...

A pilot-scale through circulation drier, using solar heated air, has been developed for drying cassava chips. The design of the drier system, which includes a bottom ventilated drying bin, centrifugal fan, and solar collector, is described. In the evaluation trials the variables studied were drie...

L.A. is the largest producer of field beans in the world (34 percent - av. of 3.85 million t/yr from 1968-71), Brazil alone accounting for more than 50 percent. Productivity is low, ranging from 330-1164 kg/ha (av 600 kg). Most of the beans are grown on small farms, often in association with othe...
