Characteristics of Colletotrichum populations associated with fruit anthracnose on chili pepper in Fiji

C. simmondsii is the predominant pathogen causing chili fruit anthracnose in Fiji. Sequence variation of additional housekeeping genes should be adopted to further understand the phylogenetic relationship of Colletotrichum species associated with chili fruit anthracnose in Fiji and those present in the other parts of the world.

Characterization of pre- and postharvest losses of tomato supply chain in Ethiopia

Results indicate that tomato production is being done by relatively young married individuals who have at least primary level education. More than 16% of respondents encounter produce losses due to high incidence of diseases, insect pest and mechanical injuries, each of them accounting for more than 20% of postharvest losses.

Too much to handle? Pesticide dependence of smallholder vegetable farmers in Southeast Asia

This study aimed to understand farmers' knowledge, attitudes, and practices regarding agricultural pest management and synthetic pesticide use in Southeast Asia. Data were used from 900 farm households producing leaf mustard and yard-long bean in Cambodia, Laos and Vietnam. Most farmers were aware of the adverse health effects associated with pesticide use and covered body parts while spraying, but also considered pesticides to be highly effective and indispensable farm inputs.

Understanding gender and power relations in home garden activities

How does home gardening fit into women's and men’s livelihood aspirations? Can home gardens address the nutritional deficiencies of household members in ways that empower women? Do men and women differ in their perceptions of the nutritional status of children? This study, undertaken as part of a collaboration between the World Vegetable Center (WorldVeg) and Stockholm Environment Institute (SEI), aims to answer these questions and inform home garden scaling-up strategies, implementation processes, monitoring and evaluation.

Vegetable diversification in cocoa-based farming systems in Ghana

As part of dynamic livelihood coping strategies, some farmers in Ghana’s cocoa belt have diversified away from traditional cocoa production to other high-value crops including vegetables, to the extent of diversifying within vegetables. This study assessed the extent of diversification of vegetables among farmers in Ghana’s cocoa belt and determined the factors that explain the variability in the diversification indices.

Weather extremes and household welfare in rural Kenya

Households in rural Kenya are sensitive to weather shocks through their reliance on rain-fed agriculture and livestock. The extent of vulnerability is poorly understood, particularly in reference to extreme weather. This paper uses temporally and spatially disaggregated weather data and three waves of household panel survey data to understand the impact of weather extremes on household welfare.

Seed yield and protein content in the Weibullsholm Pisum collection

Peas (Pisum sativum L.) and other grain legumes or rapeseed meal (Brassica napus L. subsp. oliefera) are potential sources of protein. These are also good rotation crops. For farmers, protein and yield are key traits. In this study, a dataset containing 37 descriptors and 1222 accessions from a germplasm collection of P. sativum was analyzed.

Mungbean Production under a Changing Climate – Insights from Growth Physiology

The World Vegetable Center South Asia is exploring physiology based screening approaches for identifying elite mungbean accessions for high temperature tolerance under field and controlled growth conditions. Promising selections have been subjected to elevated CO2 environments to determine their physiological responses, growth and yield abilities to help select lines with greater adaptability to the likely climates of the future.
