The effect of crop rotation and tillage practice on soil moisture, nitrogen mineralisation, growth, development, yield and quality of wheat produced in the Swartland area of South Africa

Wiese, Jacobus Daniel (Stellenbosch : Stellenbosch University, 2013-03)

ENGLISH ABSTRACT: This study was done during 2010 and 2011 as a component study within a long-term crop rotation/soil tillage trial that was started in 2007 at the Langgewens Research Farm near Moorreesburg in the Western ...
The effect of Phosphorus on the growth, plant mineral content and essential oil composition of Buchu (Agathosma betulina)

De Villiers, Chris Johan (Stellenbosch : University of Stellenbosch, 2007-12)

An increase in the demand of buchu (Agathosma betulina) oil has lead to an increase in the commercial cultivation of buchu in fields and also in hydroponic systems. A nutrient solution for hydroponically grown buchu is ...
Effect of salinity on germination and seedling growth of Canola (Brassica napus L.)

Bahizire, Francois B. (Stellenbosch : University of Stellenbosch, 2007-03)

Soil salinity is a serious constrain to crop production in many countries. In the Western Cape canola production area, large variability in soil properties within the same field is a very common feature. Some of this ...
Growth, mineral content and essential oil quality of buchu (Agathosma betulina) in response to ph under controlled conditions in comparison with plants from its natural habitat

Ntwana, Babalwa (Stellenbosch : University of Stellenbosch, 2007-12)

The Cape Floristic Region is a highly distinctive phytogeographical unit which is recognized as a floral Kingdom on its own. Buchu (Agathosma betulina) plants fall under this important Kingdom. Buchu is one of the traditional ...
Identification of soil and biological factors in crop rotation systems with significance to wheat crop performance in the Overberg production area of South Africa

Human, Hans Jurie (Stellenbosch : University of Stellenbosch, 2008-03)

A two year experiment (2004-2005) was conducted at the Tygerhoek Experimental Farm near Riviersonderend in the Western Cape Province of South Africa. The effect of different crop rotation systems on soil properties, ...
The influence of different calcium levels, irrigation methods and storage temperatures on the yield, quality and growth potential of G0 mini-tubers

De Villiers, Andre Jaco (Stellenbosch : University of Stellenbosch, 2007-12)

Calcium (Ca) is an important plant nutrient with many functions, such as strengthening of cell walls and maintaining membrane stability and cell integrity. A greenhouse experiment was conducted using an aeroponic production ...
The influence of different production systems, planting densities and levels of shading on the yield, quality and growth potential of ‘Chandler’ strawberry plants (Fragaria ananassa) grown in coir

De Villiers, Johannes Jacobus (Stellenbosch : Stellenbosch University, 2008-12)

The use of hydroponic strawberry production systems is increasing worldwide. Although higher planting densities are possible in vertical production systems, these higher planting densities may have a negative effect on ...
The influence of nutrient solutions on growth, seed production and seed quality of broccoli (Brassica oleracea L. var. italica Plenck)

Du Randt, Marius Louis (Stellenbosch : University of Stellenbosch, 2011-03)

ENGLISH ABSTRACT: Little is known about the nutrient requirements of broccoli grown for seed production. During 2006 and 2007 broccoli were grown for seed production in sand bags in a net structure, using a drain to waste ...
The interference potential of nine selected South African spring wheat cultivars with selected weed species

Nambili, Julia Nghituvali (Stellenbosch : Stellenbosch University, 2008-12)

The development of herbicide resistance in weeds is one of the major factors hampering profitable crop production worldwide. In South Africa resistance to herbicides in weeds is also a big problem, in particular in the ...
Invloed van bemesting op die opbrengs en kwaliteit van uie (Allium cepa L.)

Langenhoven, Petrus (Stellenbosch : University of Stellenbosch, 1999-03)

The Western Cape is one of the most important onion producing regions in South Africa. It is well suited for the production of intermediate daylength onion cultivars. Annually about 2500 ha are planted with a yield of ...
Irrigation scheduling of tomatoes (Lycopersicon esculentum Mill.) and cucumbers (Cucumis sativus L.) grown hydroponically in coir

Van der Westhuizen, Rykie Jacoba (Stellenbosch : University of Stellenbosch, 2009-12)

ENGLISH ABSTRACT: The use of capacitance water sensors for the scheduling of irrigation for hydroponic tomato and cucumber crops grown in coir was investigated in a series of laboratory and glasshouse experiments in the ...
Morphological and physiological responses of spring wheat (Triticum aestivum L.) to spatial arrangements

Tolmay, John Peter Cleggenett (Stellenbosch : Stellenbosch University, 2008-12)

The adoption of the no-till planting method brought about changes to the way the wheat crop is established in the Mediterranean climate of the Western Cape. Row widths have to increase from the normal narrow rows (170-180 ...
'n Ondersoek na die ontstaan van onkruiddoderweerstand in Bromus diandrus Roth

Fourie, Johan Hendrik Petrus (Stellenbosch : University of Stellenbosch, 2006-04)

ENGLISH ABSTRACT: Ripgut brome (Bromus diandrus Roth.) is a weed that causes great problems in the most wheat and grain producing areas and also in livestock practices. Until recently (1995) there were no registered ...
The physiology of seed dormancy and germination in Avena fatua L.

Cairns, Andrew Lawrence Patrick (Stellenbosch : Stellenbosch University, 1984-08)

INTRODUCTION: The study of seed dormancy and germination has for centuries occupied the minds of agronomists, physiologists, brewers, bakers and, more recently, weed scientists. The agronomist requires that the seed that ...
