Extent of soil acidity in no-tillage systems in the Western Cape Province of South Africa
(MDPI, 2020)Roughly 90% of farmers in the Western Cape Province of South Africa have converted to no-tillage systems to improve the efficiency of crop production. Implementation of no-tillage restricts the mixing of soil amendments, ... -
Developing management strategies to support sustainable production of lucerne in long-rotation cropping systems
(Stellenbosch -- Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Lucerne (Medicago sativa L.) forms part of long-rotation cropping systems integrated with livestock in the southern Cape of South Africa. The lucerne phase is five to seven years long, followed by five ... -
Factors that have an influence on splitting of malting spring barley (Hordeum vulgare L.)
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: In South Africa barley (Hordeum vulgare L.) is the second most produced small grain crop, where most of the barley is used by the beer-brewery industry for malting purposes. The Southern Cape (dryland) ... -
New perspectives on plant population and row spacing of rainfed maize
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Recent maize grain yield increases are attributed to genetic advances and changes in soil and crop management practices, including no-tillage (NT) and additional conservation agriculture (CA) practices. ... -
The influence of seed-drill choice on soil physical properties and crop performance in a semi-arid production region of South Africa
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Producers following conservation agriculture principles rely on seed-drill equipment that place seed directly in the soil. Most producers are currently using tine openers to establish their crops but the ... -
Vulnerability, institutional arrangements and the adaptation choices made by farmers in the Western Cape of South Africa
(Taylor & Francis, 2019)From 2015 to 2018, South Africa suffered from the worst drought since 1904. Climate change is predicted to increase both the frequency and intensity of droughts in parts of South Africa. In this light it is evident that ... -
Narrow rows and high maize plant population improve water use and grain yield under conservation agriculture
(American Society of Agronomy, 2020-03-11)The relationship between maize (Zea mays L.) population density and grain yield is influenced by soil and crop management strategies, including Conservation Agriculture (CA). Yet little is known about the response of maize ... -
2020-05-31 Factors influencing inhibition of glutamine synthetase enzyme in grass weeds by glufosinate ammonium under different temperatures
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: Evolution of weed resistance emphasized the need to implement integrated weed management strategies, however, farmers still immensely rely on chemical weed management. Glufosinate ammonium is an alternative ... -
The efficacy of selected herbicide-adjuvant mixtures for the control of Roundup Ready (glyphosate-resistant) volunteer maize
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: Roundup Ready (glyphosate-resistant) volunteer maize is a common occurrence in any production system where maize is planted. Volunteer maize is a result of maize seeds or ears that escaped harvesting in ... -
The ecological sustainability of potato production in the sandveld region of the Western Cape: nutrient and water use efficiencies
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: Uncertainty regarding the rate at which water and nutrients move and are distributed throughout the soil profile is key in managing potato production systems in the Sandveld region of the Western Cape. ... -
High nitrogen rates do not increase canola yield and may affect soil bacterial functioning
(American Society of Agronomy, 2019)Nitrogen fertilization has a fundamental role in agricultural productivity. However, injudicious N applications to crops are common. It is important to ensure the minimum N required for satisfactory crop growth is applied ... -
Direct and indirect methods of estimating lucerne (Medicago sativa) yield
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: Lucerne (Medicago sativa) is an important drought tolerant fodder crop which plays an important role in providing feed for livestock in South Africa. Currently, the standard method for determining fodder ... -
Exploring the potential of urban vertical farming : economic and technological analyses
(Stellenbosch : Stellenbosch University, 2019-03)ENGLISH ABSTRACT: Food security is defined as the situation in which all people are able to achieve access to sufficient, safe and nutritious food at all times in order to maintain a healthy and active lifestyle. Food ... -
Optimizing the use of pre-emergent herbicides in wheat production, under conservation agriculture practices in the South-Western Cape Region
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: The interception of herbicide by residue cover can result into poor weed management, leads to more weed seeds reaching the soil seed bank, which results in higher weed pressure in the following seasons ... -
Wheat and canola establishment in the Western Cape : openers, nitrogen placement and planting depth
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: Wheat, the main cereal crop and canola, the main oilseed crop are the two most prominent crops established in the Western Cape under dryland conditions. Tine openers are most commonly used to establish ... -
Utilisation of cover crops : implications for conservation agriculture systems
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: Cover crops have the potential to address some limitations in conservation agriculture systems with a Mediterranean climate. These limitations include, but are not limited to, a lack in crop diversity, ... -
The influence of manganese on glyphosate efficacy in ryegrass (Lolium spp.)
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT: In the Western Cape of South Africa, ryegrass (Lolium spp.) developed resistance to the herbicide glyphosate within wheat fields, orchards and vineyards. The influence that plant available Mn might have ... -
Effects of light manipulation through different photo selected net colours and LEDs (Lactuca Sativa L.) and cabbage as estimated by chlorophyl fluoressence parameters, macro and micro element content and physical measurements.
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT: Light quantity and quality plays a fundamental role in seed germination, plant growth and development. Plants grown in high radiation regions can experience light stress, resulting in photoinhibition when ... -
Developing nitrogen fertiliser management strategies for canola (Brassica napus L.) under conservation agriculture practices in the Western Cape
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT: Nitrogen (N) is one of the most important nutrients in canola production systems. Improper N supply due to lack of knowledge regarding canola N management and inappropriate fertiliser guidelines, frequently ... -
