Vegetable production is vital to smallholder farmers, who often struggle overcome pests, diseases, and extreme weather. Agroecological cropping systems offer sustainable solutions these issues but their adoption rates in Tanzania remain low. This study examines the factors influencing farmers’ of selected agroecological for vegetable Tanzania, which remains underexplored. Using a multistage sampling technique, cross-sectional data were gathered from 525 crucifer traditional African farming...
This study quantifies the adoption of improved amaranth varieties in Kenya and Tanzania, extent to which these result from international vegetable breeding research conducted by World Vegetable Center (WorldVeg) partners. The used expert elicitation a questionnaire survey among seed producers. Nine panels were involving 123 local experts. results show that planted on 51% area 70% Tanzania. Improved 17,502 ha reached 404 thousand smallholder farmers. WorldVeg is main source varieties,...
Vegetables are sources of vitamins, minerals and income for those involved in production marketing. Having first-hand information about vegetable marketing system is essential to devise appropriate strategies aimed at enhancing value chain development. It was line with this view that a study conducted characterize systems selected sites the humid tropics Ethiopia. Data were collected using participatory primary survey techniques augmented secondary data. While area cultivated vegetables has...
Abstract Amaranth ( Amaranthus spp.) is an underutilized crop increasing in popularity as a grain and leafy vegetable. It rich protein, minerals, vitamins, adapts well to range of production systems. Currently, the lack improved cultivars limits use crop. Breeding‐improved requires access large collections amaranth biodiversity stored genebanks. The task searching such vast for traits interest can be eased by generating core collections, which display diversity much smaller germplasm set....
African leafy vegetables are becoming important crops in tackling nutrition and food security many parts of sub-Saharan Africa, since they provide micronutrients vitamins, help resource-poor farm families bridge lean periods shortage. Genetic diversity studies essential for crop improvement programmes as well germplasm conservation efforts, research on genetic these using molecular markers has been increasing over time. Diversity have evolved from the use morphological biochemical to...
Amaranth (Amaranthus spp.) is a popular crop grown throughout sub-Saharan Africa, where both the grain and leaves are consumed. cultivars that offer multiple options to small-scale farmers produce high foliage yields, or yields would be desirable. The objective of this study was determine effects leaf harvests on yield nutrient content diverse amaranth entries (breeding lines cultivars). Trials were conducted at World Vegetable Center in Arusha, Tanzania 2013 2014. Seventeen evaluated for...
Consumption safety of Solanum scabrum berries is controversial in different cultural practices and evaluation the toxicity as well micronutrition value relies on relevant phytochemical study. Thus, this study aimed to systematically profile phytochemicals from genetic sources maturity. Using a combination three complementary methods HPLC-UV/Vis-MS or MS/MS with acid-assisted hydrolysis, total 54 were identified including polyphenols, saponins toxic glycoalkaloids. Particularly, broad range...
Abstract Cleome gynandra (L.) Briq. is an African leafy vegetable with a potential to improve food security and micronutrient deficiencies. Cytological traits, breeding biology genetic diversity of 30 selected entries C. from six countries were investigated. The consisted advanced lines, gene bank accessions farmers’ cultivars. Our study revealed chromosome numbers 2 n = 34 in root tip metaphase cells one entry. found be diploid genome sizes ranging 2.31 2.45 pg/2C. Hand pollination...
Amaranth is one of the most commonly produced and consumed indigenous vegetables on African continent. In Tanzania amaranth constitutes about 5.3% total vegetable hectarage planted annually. Most cultivated varieties are landraces with relatively poor leaf grain yield. This study was conducted to identify genotypes potential for dual purpose (leaf grain) use promotion or further cultivar development. An experiment carried out in two seasons at AVRDC - The World Vegetable Center Arusha, from...
African nightshades are becoming more important as leafy vegetables in sub-Saharan Africa. Previously considered food for the poor, their cultivation is now being promoted, and some cultivars commercialised; however, most farmers use self-produced seeds, leading to low varying yields. Improvement through conventional breeding depends on available genetic diversity, possible systems, nutritional value of accessions. Therefore, we review information these topics with following main outcomes:...
Amaranth ( Amaranthus sp.) is an important leafy vegetable in Africa where most farmers grow unimproved landraces. Information about amaranth genetic diversity and its adaptation to different environments will help breeders develop improved commercial varieties that meet market requirements. The objectives of this study were investigate the performances entries for yield across locations seasons, assess relative contributions vs. environmental sources variation yield, cluster into...
African eggplant ( Solanum aethiopicum L.) is one of the most common traditional vegetables in Tanzania and Uganda, but its productivity severely affected by wilt diseases caused a number pathogens. Plant stem root samples were collected several fields from many neighboring diseased healthy plants Gilo group Shum Uganda to identify putative pathogens causing on eggplants. Through amplicon sequencing sampled tissues, we identified causal for symptoms. Wilting S. likely bacterial pathogen...
Vegetable amaranth ( Amaranthus sp.), a leafy vegetable crop consumed around the world, is actively promoted as source of essential micronutrients to at-risk populations. Such promotion makes micronutrient content underlying value this crop. However, extent which varies by effect genotype not clear, leaving breeders uninformed on how prioritize contents criteria for selection among other performance parameters. A total 32 entries across seven species were field-grown and analyzed Fe, Mg, Ca,...
