Locally there is cultivation of vegetables in greenhouse as a production system; however it is not common to use honeybee as pollinators. This might be due to a fear of low pollination efficiency or activity of local bees under caged condition. Moreover there is no research related to the foraging behavior of local honeybee under caged condition. Hence, this investigation was designed to study foraging behavior of... Read more.

The Terminalia catappa L., popularly referred to as Indian almond, adapts to different soil and climatic conditions. It is a fast growing tree and has been widely used for ornamental and medicinal purposes. This plant might also be used as a carbon sequester in areas subject to soil and water salinity problems. This paper aims at studying the balance of salts among parts of the Indian almond tree under different... Read more.

Xanthomonas wilt (XW) caused by Xanthomonas campestris pv. musacearum (Xcm) is an important constraint to banana production in East and Central Africa. The use of clean planting materials (CPM) for establishing new fields/ re-planting rouged fields/mats is recommended. However, banana is mainly produced by resource-poor small-holder households with no/limited access to CPM. We assessed XW incidence in fields planted... Read more.

Post-harvest management of sweet potatoes (SP) crop residues preserves nutrients, deactivates inhibitor compounds and improves rumen degradation. The aim of the study was to determine effects of drying crop residues and heating roots on forage value of a bio-fortified orange fleshed sweet potato (OFSP) variety in South Africa. The crop was harvested at maturity and roots separated from crop residues. Roots were washed,... Read more.
