The El Niño - Southern Oscillation, rainfall and wheat yields in South Africa
… rainfall and South African commercial winter wheat yields from 1974 - 2000. The analysis is through a combination of the Pearson's product moment correlation coefficient and an assessment of the magnitude and consistency of rainfall and wheat anomalies in the year of, and the year following …

Investigating the relationships between wheat-specific rainfall characteristics, large-scale modes of climate variability and wheat yields in the Swartland region, South Africa
Wheat producers in the South Western Cape (SWC) of South Africa need to cope with biophysical and socio-economic systems exposing farmers to a multidimensional decision- making environment. The rain fed wheat production in the Swartland region is highly susceptible to the interannual variability of …

Evaluating an Advanced Intensive Management Strategy for Virginia Wheat
Current Virginia soft red winter wheat (Triticum aestivum L.) management strategies have been in place for over 20 years. A new advanced intensive management (AIM) system has been evaluated in order to improve Virginia wheat yields and attempt to bring state average wheat yields of 4288 kg ha⁻¹ …

Modelling impacts of climate variability and change on wheat cropping across New South Wales
Wheat is the most important crop in Australia in terms of the gross value of production. However, in Australia wheat yield is extremely variable from year to year among major production regions, such as New South Wales (NSW), with its agricultural system being significantly affected by water stress …

Modelling the impact of future climate change on subregional wheat production in the Western Cape
… coupled with changes in rainfall will impact wheat yields (the province’s dominant field crop), little information exists to guide adaptation planning, especially on the potential range of climate change impacts on dryland winter wheat production. Furthermore the Western Cape is a highly …

Exploring relationships between root architecture and growth of UK wheats (Triticum aestivum L.)
… period, growing deep rooting cultivars increased wheat yields by approximately 15%. Seedling root angle is associated with adult root system depth in Australian field-grown wheat cultivars (Triticum aestivum L.), but it is not yet known whether selection for root angle and rooting depth could …

The Influence of Soil Reconstruction Methods on Mineral Sands Mine Soil Properties
… were cropped to corn (Zea Mays L.) in 2005 and wheat (Triticum aestivum L.) in 2006. Yields were compared to nearby unmined prime farmland yields. Over both growing seasons, the two biosolids treatments produced the highest overall crop yields. The Topsoil treatment produced the lowest corn …

Improving the thermal tolerance of photosynthesis in wheat
Wheat yields need to rise to meet growing demands due to population growth and changing diets. Additionally, the resilience of crop yields to climate change and rising temperatures needs to be improved. Inhibition of photosynthesis under sub-optimal environmental conditions decreases carbon …

AFLP markers linked to Fusarium head blight resistance in Triticum aestivum.
… disease of cereal crops that results in reduced wheat yields, discoloured, shrivelled kernels, mycotoxin accumulation, and reduced seed and grain quality. Since resistance mechanisms in wheat are complex, often being confounded by environmental effects, and there is high genotypic variance for …

The effect of non-glaucousness, as conferred by Inhibitor of Wax 1, on physiology and yield of UK Wheat
… of key roles in plant physiology. Although the wheat wild progenitors display a diversity of epicuticular wax phenotypes, the glaucous (visible wax) phenotype dominates cultivated varieties. However, the UK winter wheat variety Shamrock is unusual in that it exhibits a non-glaucous phenotype, …

The Impacts of Drought on Wheat Yield and Farmers' Livelihood in the Swartland Region of the Western Cape South Africa
… recent years, which have led to declines in crop yields and have negative implications on the production of non-irrigated crops such as wheat. This study examined the sensitivity of winter wheat to drought during its growing season in the Swartland region, to assess the drought induced declines in …

An investigation into the chloroplast transformation of wheat, and the use of a cyanobacterial CCM gene for improving photosynthesis in a C3 plant
Wheat is a major component of the UK diet, and provides approximately 20% of global caloric intake. Wheat is grown on more land area than any other crop, and the continued supply of wheat is essential for global food security. Biotechnology is likely to play an important role in the sustainable …

The Economic Benefits of the South African Agricultural Research Council’s Wheat Breeding Program: 1992–2015
… specifically in plant breeding to increase yields and help mitigate future food insecurity. To fill this need, the South African government funds the Agricultural Research Council (ARC), which conducts holistic research on wheat and other crops. Wheat is important to South African food …

Nitrogen Acquisition of Pea-Oat and Pea-Canola Intercrops and Their Impact on Subsequent Wheat Crops
… Melfort, and Redvers, Saskatchewan followed by wheat in the subsequent year. Each of the intercrops were supplied with three N fertilizer rates (0, ¼, ½ of their recommended rate), while the monocrops (pea, oat, canola) received their full recommendation of N fertilizer, except pea which …

Enhancing photosynthetic capacity and energy conversion in wheat
Wheat is one of the major grain crops worldwide and provides approximately 20% of the total caloric and protein input for the world’s population. An increase in crop yields is required to meet the demands of the increasing world population in a challenging scenario of less predictable climatic …

Genotype and Nitrogen fertilizer influence on Grain yield and protein content of wheat(Triticum aestivum L.)
The grain yield of wheat in Lesotho is low because of poor soil fertility, and the wheat is regarded by the millers to be of poor quality and therefore of less value. A field study was therefore conducted at three sites in Lesotho( Maseru, Leribe and Mafeteng) to evaluate the influence of genotype …

Assessing long-term conservation of groundwater resources in the Ogallala Aquifer Region using hydro-agronomic modeling
… parameters significantly affect crop yields, especially for maize and sorghum, and soybean and winter wheat yields are sensitive to a combination of cultivar genetic parameters, soil-related parameters, and climate-related parameters; 2) Climatic parameters account for 44%, 29%, 40%, …
