Modelling the production potential of land for sugarcane in the KwaZulu-Natal Midlands sugarcane belt.
(2000)Commercial sugarcane records for 19 seasons from 146 fields were obtained from selected estates in the KwaZulu-Natal Midlands. The estates, located at Kranskop, Umvoti and Richmond, are representative of the higher-potential ... -
Moderation of growth and sucrose flux in sugarcane by temperature.
(2005)Sugarcane plants (cultivar NCo376) were studied to assess the effects of temperature and season (spring and autumn equinox) on the morphological and physiological response of stalk components. Plants were grown from ... -
Nitrogen in the soil-plant system of successive rainfed wheat crops under conventional cultivation.
(2002)Soil mineral N and soil water content at planting, biomass accumulation, yield and grain quality parameters (hectolitermass and protein percentage) were measured on an unfertilized and recommended-N-application treatment ... -
Nutrient studies in potatoes (Solanum tuberosum)
(1997)One of the biggest problems facing potato (Solanum tuberosum) production in Kwazulu-Natal is acidic soils with high a aluminium content. Traditionally, such soils were ameliorated using lime, thus increasing soil pH, Ca ... -
Nutritional value of bambara groundnut (Vigna subterranea (L.) Verdc.) : a human and animal perspective.
(2014)Bambara groundnut (Vigna subterranea (L) Verdc.) is an indigenous African legume that is reported to have wide adaptation to a range of environments. It is popular among subsistence farmers in sub-Saharan African. However, ... -
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 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 ... -
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 ... -
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 ...
