Early establishment performance of local and hybrid maize under two water stress regimes
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: T. Mabhaudhi --- , Pietermaritzburg A.T. Modi --- , PietermaritzburgMaize (Zea mays L.) is the major grain crop in South Africa where most subsistence farmers still plant landraces. The objective of this study was to compare two landrace selections of maize with two hybrids popular among small-scale farmers in... -
Growth, phenological and yield responses of a bambara groundnut (Vigna subterranea (L.) Verdc.) landrace to imposed water stress under field conditions
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Tafadzwanashe Mabhaudhi --- Crop Science, School of Agricultural, Earth and Environmental Sciences, South Africa AlbertT Modi --- Crop Science, School of Agricultural, Earth and Environmental Sciences, South AfricaBambara groundnut (Vigna subterranea (L.) Verdc.) is an underutilised species with potential to contribute nutritional and food security in marginal areas. Growth, phenology and yield of a local bambara groundnut landrace from Jozini, KwaZulu-Natal, characterised into three selections according to... -

Item type: Journal Article • Journal: The Southern African Forestry Journal • Authors: M. Herbert --- Department of Forest Biology, Faculty of Forestry & Nature Conservation, Tanzania A. G. Mugasha --- Department of Forest Biology, Faculty of Forestry & Nature Conservation, Tanzania S.A.O. Chamshama --- Department of Forest Biology, Faculty of Forestry & Nature Conservation, TanzaniaPerformance evaluation was conducted among nineteen provenances of Calliandra calothyrsus from mesa-America, Indonesia and Tanzania. Two trials were established in February and March, 1996 at Gairo (8 provenances) and Sokoine University of Agriculture (SUA) Farm (17 provenances) in Morogoro, Tanzania... -
A genetic diversity analysis of South African sorghum genotypes using SSR markers
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Alina Mofokeng --- African Centre for Crop Improvement, School of Agricultural, Earth, and Environmental Sciences, South Africa Hussein Shimelis --- African Centre for Crop Improvement, School of Agricultural, Earth, and Environmental Sciences, South Africa Pangirayi Tongoona --- African Centre for Crop Improvement, School of Agricultural, Earth, and Environmental Sciences, South Africa Mark Laing --- African Centre for Crop Improvement, School of Agricultural, Earth, and Environmental Sciences, South AfricaDiverse landraces of sorghum (Sorghum bicolor (L.) Moench) are widely grown by smallholder farmers in South Africa. The objective of the study was to assess the genetic diversity present in South African sorghum genotypes using genetic distances as measured by... -
Genetic diversity of bottle gourd (Lagenaria siceraria (Molina) Standl.) landraces of South Africa assessed by morphological traits and simple sequence repeat markers
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Jacob Mashilo --- Towoomba Research Station, Limpopo Department of Agriculture, South Africa Hussein Shimelis --- African Centre for Crop Improvement, South Africa Alfred Odindo --- Crop Science Discipline, South AfricaBottle gourd (Lagenaria siceraria (Molina) Standl.) is an important crop in rural communities in South Africa but it remains under-researched. The objective of this study was to assess the genetic diversity present amongst bottle gourd landraces grown by smallholder farmers... -
Variation in morphology and yield traits of Cucurbita landraces in northern KwaZulu-Natal, South Africa
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Nontuthuko R Ntuli --- Department of Botany, Faculty of Science and Agriculture, South Africa Rufaro M Madakadze --- African Crop Improvement Alliance for a Green Revolution in Africa, Kenya Alpheus M Zobolo --- Department of Botany, Faculty of Science and Agriculture, South AfricaPumpkins, represented by various Cucurbita species, are important traditional leafy vegetable crops that are widely eaten in KwaZulu-Natal, South Africa, and elsewhere. Cucurbita landraces are exceptionally variable in morphology and productivity. Although these vegetables are grown extensively in South Africa,... -

Provenance trials of teak were established in the 1970s in Ghana, as part of the... -
Pigeonpea production constraints and farmers’ trait preferences in Malawi: implications for variety design
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Esnart Nyirenda Yohane --- , South Africa Hussein Shimelis --- , South Africa Mark Laing --- , South Africa Admire Shayanowako --- , South Africa Isack Mathew --- , South Africa Justus M Chintu --- , MalawiPigeonpea Cajanus cajan (L.) Millsp. is the most important legume cash crop grown in Malawi. However, productivity is low due to biotic and abiotic stresses and socioeconomic constraints. The objectives of this study were to determine farmers’ perceived constraints to...
