The effect of rainfall and temperature on the preharvest sprouting tolerance of winter wheat in the dryland production areas of the Free State Province
Annelie Barnard,Marie F. Smith +1 more
TL;DR: Principal component analysis on mean PHS values identified three distinct groupings of cultivars, ranging from PHS susceptible to PHS resistant, indicating that certain cultivars are more sensitive to environmental effects than others and that the variation in cultivar PHS is not consistent across sites and years.

Soil fertility constraints and yield gaps of irrigation wheat in South Africa
Nondumiso Z. Sosibo,Pardon Muchaonyerwa,Lientjie Visser,Annelie Barnard,Ernest Dube,Toi J. Tsilo +5 more
TL;DR: In this paper, the authors explore opportunities for improving yields in intensive irrigated wheat production systems of South Africa through analyses of yield gaps, soil fertility constraints and conservation agriculture practices, and conclude that yields could be increased by 26-38% through closing yield gaps.
Determination of the influence of climate on falling number of winter wheat in the dryland production areas of the Free State Province of South Africa
Annelie Barnard,Marie F. Smith +1 more
TL;DR: Results from this study indicated that rainfall during the later stages of grain filling and grain maturity had a negative effect on the FNs of 7 of the 11 cultivars, while maximum temperatures during these growing periods were positively correlated with FN in 8 of the11 cultivars.

Determination of the preharvest sprouting resistance of South African winter wheat (Triticum aestivum L.) cultivars
TL;DR: This study classified the preharvest sprouting resistance of 17 South African winter wheat cultivars sampled over a range of typical winter wheat growth environments into four distinct groups ranging from resistant to susceptible.

Genetic progress of spring wheat grain yield in various production regions of South Africa
Ernest Dube,Willem Kilian,Learnmore Mwadzingeni,Nondumiso Z. Sosibo,Annelie Barnard,Toi J. Tsilo +5 more
TL;DR: In this paper, a periodic evaluation of the genetic gains in grain yield is presented, based on a series of informed production decisions, including availing stable and high yielding cultivars.
