Abstract: The green leafhopper Empoasca decipiens Paoli (Homoptera: Cicadellidae) has recently become a serious pest of vegetables and ornamentals grown under field conditions and in greenhouses in many European countries. The egg parasitoid Anagrus atomus L. (Hymenoptera: Mymaridae) is a promising biological control agent of E. decipens. The objectives of this research were to assess the influence of host plants on the leafhopper and its parasitoid. Therefore, host plant acceptability ans s...
Abstract: Several decisions are made by farm households with family members who contribute labor, time, and knowledge, and by those who have stake in all activities of households. These members mainly include the household head (male or female), spouse, productive youth, and the elderly. Rural women in the developing world in general and throughout Ethiopia in particular make critical contributions to household agricultural production and consequently to household and national food security....
Abstract The postharvest losses in fruits and vegetables in developing countries vary between 15-90%. Many organizations are actively promoting the processing of fruits and vegetables to find a solution to the difficulties encountered in storing large quantities of fresh produce without incurring heavy losses. This study evaluated the chemical, microbiological and sensory properties of leather blends produced from 'Ogbomoso' mango and carrot. Purees of mango (Mangifera indica 'Ogbomoso') and...
ABSTRACT Background: The link between food retail environment and health disparities continue to grow. Assessment of the food environment is one key strategy in undertaking healthy food retail initiatives. However, little is known about the retail food environment in developing countries like Ghana. This study therefore, aimed to examine the food retail environment in the Tamale Metropolis. Methods: This study was a descriptive cross-sectional study and employed simple random sampling techni...
Abstract Rhizosphere studies of two local green vegetables, Celpsia argentea Linn and Hibiscus esculentus. Linn (new name Abelmoschus esculentus) were studied from vegetative stage to senescence. The viable seeds of both vegetables were collected and planted on garden beds made from sandy loam soil. Samples were collected at two-week intervals at 9.00 hrs in the the morning. Morphologically, A. esculentus (okra) had 3 leaves with more dense rooting system at 2 weeks than C.argentea (solo) wit...
ABSTRACT The fact that evaluating economic performance of irrigation schemes are important and therefore needed at regular intervals is actually the motivation behind this study. Major objective of the study is to provide information that can be used to improve performance of the Farmer Managed Irrigation Schemes in Tanzania in terms of; economic returns to farmers, water use efficiency and productivity, operation and maintenance and sustainability of the schemes. The study area covered thre...

ABSTRACT During the past two decades, agricultural scientists in Kenya in collaboration with International Potato Centre have released numerous new varieties, developed improved Irish potato management practices, and actively worked with government agencies, NGOs and farmer groups to ensure that these improved technologies are widely available to farmers. However data on national Irish potato production in Kenya fail to demonstrate that these efforts have had an impact on national mean yield...
ABSTRACT Declining water resources, low rice yields and a widening gap between current rice demand and production in Zanzibar necessitates a change from the current rice production system to a more efficient system of production such as the system of rice intensification (SRI). In an attempt to evaluate the efficacy of SRI practice and determining the optimum spacing and transplanting age of seedlings for better grain yield, productive tillers and water productivity, a field experiment in a R...

ABSTRACTThe need to improve our vegetable protein consumption in order to reduce the incidence of protein deficiency diseases cannot be over-emphasized. This research was premised on evaluating the appropriate levels of substitution of cow milk with soya milk to produce composite yoghurt. Eight hundred (800) grams of soya bean seeds after sorting out foreign materials and washing were usedto produce 4.0 liters of soya milk (20% total solids). Cow milk (20% TS) was blended with soya milk in th...
ABSTRACT The production of high quality foam was carried. The actualization of the production of polyurethane (fibre) foam was made possible by using the components / chemical raw materials such as polyol (polyurethes resin). TDI (toluene di-Iso-cyanate, methylane chloride (MC)-(CH2CL). Silicon oil, stannous octoate, calcum carbonate and water. As a result of chemistry of polyurethane foams, properties of foams and fibre materials (physical, chemical, thermal and mechanical properties...
ABSTRACT Production of vegetables in the smallholder sector of sub-Saharan Africa (SSA) is affected by poor soil fertility with nitrogen (N) being the most limiting nutrient. Continued nutrient mining without adequate replenishment has led to a corresponding decline in soil fertility and crop yields due to failure by farmers in SSA to purchase inorganic fertilisers. Leguminous multipurpose tree (MPT) prunings have widely been promoted as alternative sources of N but nutrient release is affect...
ABSTRACT There is an emerging and expanding demand for food of animal origin both in the domestic and export markets. Farmers are hence expected to exploit and increase their demand for more adoptive and productive animals. This is in line with the current “Kilimo Kwanza” initiatives and the on going National Strategy for Growth and Reduction of Poverty (NSGRP) as envisaged in the Tanzania Development Vision 2025. There has been initiative with insignificant results since colonial times t...
