Performance evaluation of a mixed-mode solar dryer for evaporating moisture in beans
This research includes the design and manufacture of a solar dryer and its performance test on bean. Solar dryer consists of three parts; 1) the air heating section (solar collector), 2) two fins and 3) the drying chamber section with four trays. The drying test was conducted after setting the drying air speed at 1.5 m/s at the drying chamber. The drying process continued until the total beans weight was (100...

Effect of ridge height and planting orientation on Ipomea batatas (sweet potato) production
Ipomea batatas (sweet potato) yield vary widely among farmers due to improper ridging and planting orientation. This study was to establish the proper ridging and planting orientation, so as to enhance constant reliable yields among sweet potato producing farmers. The objectives of the study were to compare vine length and to determine root yield, central root diameter and root length among...

Brassica carinata (BBCC, 2n = 34) has still to emerge as a major oilseed crop owing to poor agronomic attributes like long stature, long maturity duration and low seed yield. The restricted amount of genetic variability available in natural B. carinata necessitates utilization of new sources of variability for broadening the genetic base of the source population. Interspecific hybridization...
