Field assessment of agronomic traits and in vitro acetolactate synthase characterisation of imazapyr herbicide tolerant sugarcane.
(2013)Weed control is a major cost for growers in the sugarcane industry, especially for monocotyledonous species such as Cynodon and Rottboellia spp. The introduction of imazapyr-tolerant sugarcane would be advantageous as this ... -
Food security potential of bottle gourd [Lagenaria siceraria (Molina Standly)] landraces : an agronomic perspective.
(2014)Issues surrounding food security of rural households in sub-Saharan Africa have become topical in the recent years due to low food production and poverty combined with increasing population which often leads to malnutrition. ... -
Genetic diversity, correlations and path coefficient analysis in popcorn (Zea mays L. everta)
(2012)Popcorn is the most popular snack food in the world. Genetic diversity is of major concern in popcorn breeding. High genetic diversity allows manipulation of different genotypes to breed new varieties. There is very little ... -
Growth and yield responses of cowpeas (Vigna unguiculata L.) to water stress and defoliation.
(2012)Cowpea (Vigna unguiculata L.) is an important legume, especially in the hot, dry tropics and subtropics of sub-Saharan Africa. It has been widely reported to be drought tolerant. Cowpea is a highly nutritious, multi-purpose ... -
Growth parameters, maize (Zea mays L.) silage and bambara groundnut (Vigna subterranea L.) grain yield in an intercropping system.
Intercropping is practised throughout the tropics with a range of different crop combinations. As sustainable agriculture includes the enhancement and management of natural resources while meeting the human and animal needs ... -
Interactive effects of weeding regimes and seed shapes on growth, yield and nutrient compononents of SC701 green mealies during summer and winter planting seasons under rain-fed condition.
(2013)Maize and weeds interfere with growth activities of each other to a varying degree. Weeds compete for water, mineral nutrients, and light and hinder harvest operations. Maize plants are susceptible to weed competition ... -
Intercropping of maize and dry beans for the Vulindlela district of KwaZulu-Natal.
(1997)The use of a maize/bean intercropping system to improve land productivity was investigated after limited land availability had been identified (Liebenberg, 1993) as a major constraint to crop production in the Vulindlela ... -
Investigating crop rotational benefits of a soybean and sugarcane cropping system in South Africa.
(2013)Crop rotation is not commonly practised in the sugarcane industry in South Africa. It has, however, proven to be beneficial to other crops in South Africa. The objective of this study was to determine the impact of ... -
Investigating the role of polygalacturonase in cotyledonal cracking of green beans (Phaseolus vulgaris L.)
(2005)Transverse cotyledonal cracking (TVC) was characterised at physiological, biochemical and molecular levels in three common bean (Phaseolus vulgaris L.) cultivars: Imbali, Tongaat and Tokai. The incidence of TVC was ... -
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 ...
