Drying behavior of blanched sweet potato in a cabinet dryer using different five air temperatures (40-80°C) and ten sweet potato varieties sliced to 5mm thickness were investigated. The drying data were fitted to eight models. The Modified Henderson and Pabis model gave the best fit to the experimental moisture ratio data obtained during the drying of all the varieties while Newton (Lewis) and ...

Transgenic plants expressing a foreign gene are a suitable system for the production of relevant immunogens in high amounts that can be used for the development of a new generation of vaccines against a variety of infectious diseases. In the present study, the expression of the nucleocapsid (N) protein of hantavirus serotype Puumala in tobacco and potato plants was investigated. Transgenic toba...

The physical attributes of agricultural product are utmost essential in developing technologies for different unit operations. Pertinent potato tuber were studied. 100 samples dominant and popular varieties grown Ethiopia which free from any injuries each variety obtained Holeta Agricultural Research Center. In this study, the tubers determined at a moisture content 70.75, 69.99, 71.75, 69.70 7...

Sweet potato (Ipomoea batatas) is an important subsistence and famine reserve crop grown in developing countries where Sweet potato chlorotic stunt virus (SPCSV; Closteroviridae), a single-stranded RNA (ssRNA) crinivirus, synergizes unrelated viruses in co-infected sweet potato plants. The most severe disease and yield losses are caused by co-infection with SPCSV and a potyvirus, Sweet potato f...

Various densities of adult potato leafhoppers were established on 'Essex' soybean at plant growth stage V2 in caged field plots. Cages were removed two weeks later, and plots remained uncaged for the rest of the growing season. Direct counts of nymphal leafhoppers on plants shortly after cage removal confirmed that a gradient of infestation levels was attained. In both years of the study, highe...
