Pepper and tomato seed performance in response to imbibition and dehydration.
(2005)The International Seed Testing Association and the Association of Official Seed analysts define seed vigour as the ability of a seed lot to perform during the germination process and crop stand establishment under a wide ... -
Performance of wild watermelon (Citrullus lanatus L.) in response to population density and mulch.
(2012)The wild watermelon, Citrullus lanatus L. was among the most important foodstuffs to a number of African communities, until the colonists introduced their own foodstuffs in a process that was highly supported by the laws ... -
Physiological responses of cowpea (Vigna unguiculata) to water stress under varying water regimes.
(2014)Water stress has been reported as one of the most important environmental factors affecting crop productivity in the world, particularly in semi– and arid regions. Climate change, through changes in rainfall amount and ... -
Phytate related response of maize seed to phosphorus and temperature.
(2006)The aim of the study was to determine the effect of day/night temperatures (22/l6°C, 2712l oC and 33/27°C) and phosphorus levels (0, 0.12 and 1.2g per 20 kg soil) on seedling establishment and seed viability during three ... -
Phytotron and field performance of Taro [Colocasia Esculenta (L.) Schott] landraces from Umbumbulu.
(2006)The taro landraces that are most preferred by farmers from Umbumbulu, KwaZulu-Natal were identified through focus group discussions with farmers. Farmers ranked taro landraces on the basis of preference as determined by ... -
Planting date effects on growth, development and yield of selected agronomic crops at Makhathini Irrigation Scheme.
(2014)Agriculture, as a source of rural livelihood, is currently faced with challenges such as increasing temperatures, floods, and drought frequency associated with climate change and variability. Climate change is associated ... -
Planting date, water availability and plant density effects on dry bean production (Phaseolus, vulgaris L.).
(2017)Dry beans (Phaseolus vulgaris L.) form an important part of the agricultural system in southern Africa. Small scale farmers use the crop in crop rotation or intercropping with another staple crop, maize. Although commercial ... -
Planting density effect on growth and yield of taro (Colocasia esculenta) landraces.
(2015)Taro (Colocasia esculenta), or amadumbe (in isiZulu), currently occupies low levels of utilisation in South Africa. Information describing its agronomy is still scant. The aim of this study was to determine the effect of ... -
Position of amaranthus seed on the plant in relation to seed quality and productivity under varying water regimes.
(2018)Amaranth is one of the important vegetables that are highly nutritious in protein, iron, vitamins A, C, and K. Its nutritional value can be used to reduce food insecurity, poverty and malnutrition problems in South Africa ... -
Pot trial phenotyping to predict sugarcane genotype field performance with the canegro model.
(2016)Abstract available in PDF file. -
Response of dual-purpose cowpea landraces to water stress.
(2013)Cowpea (Vigna unguiculata (L.) Walp) is an important protein-rich grain legume of major economic importance. It is widely grown by small-scale farmers in the arid and semi-arid regions of the world where it is cultivated ... -
Response of local wild mustard (Brassica species) landraces to water stress.
(2010)Wild mustard is an indigenous leafy vegetable. Its use is limited by a lack of knowledge of its agronomy. However, it is a rich source of nutrients and other minerals. Nowadays, the use of indigenous crops has been replaced ... -
Response of potato genotypes to production sites and water deficit imposed at different growth stages.
(2020)In South Africa, potato is an important food security crop widely cultivated by smallholder farmers due to its extensive adaptation characteristics. However, drought adaptive responses of potato genotypes vary under ... -
Response of primed soybean (Glycine max L.) to storage duration and ambient conditions.
(2022)Abstract available in PDF. -
Responses of Bambara groundnut (Vigna Subterannea L. Verdc) landraces to field and controlled environment conditions of water stress.
(2012)Bambara groundnut (Vigna subterranea L. Verdc) is a drought tolerant African legume capable of producing reasonable yields where other crops may fail. However, it remains an underutilised crop, owing to limited research, ... -
Responses of maize (Zea mays L.) landraces to water stress compared with commercial hybrids.
(2009)Local maize landraces have evolved over hundreds of years of natural and farmer selection under varying conditions. These landraces may have developed tolerance to abiotic stresses such as water deficits during this cycle ... -
Screening groundnut (Arachis hypogaea L.) genotypes for tolerance to soil acidity.
(2011)Groundnuts (Arachis hypogaea L.) are an important subsistence and cash crop for smallholder farmers in Southern Africa. They require well drained light textured soils. However, most light textured soils are acidic and ... -
Screening of cover crops under conservation agriculture.
(2016)The practice of conventional tillage results in land degradation, reducing soil fertility due to soil erosion. Conservation agriculture aims at reducing soil disturbance which brings benefits of soil conservation. The call ... -
Seed quality and water use characteristics of a bambara groundnut (Vigna subterranea L.) landrace differing in seed coat colour.
(2014)Bambara groundnut (Vigna subterranea L.) is an underutilised African legume that fits the same ecological niche as Arachis hypogea (groundnuts). Because of its reported drought tolerance and high water use efficiency ... -
Seed quality and yield of selected traditional and commercial crops : vegetable water use and nutritional productivity perspectives.
