The economics of large scale wheat production in Zimbabwe
This study traces the evolution of the wheat industry in Zimbabwe and draws historical lessons for a food policy aimed at self-sufficiency in wheat. An activity analysis approach to the problem of wheat production is presented. The approach employs questionnaire survey data to construct wheat …

Determination of Poultry Litter's Nitrogen-Fertilizer Value for Winter Wheat Production
… in the fall as a nutrient source for winter wheat (Triticum aestivum L.) has not been adequately characterized. Our objective was to determine a potentially available N (PAN) coefficient based on the inorganic-N fertilizer equivalence (FEQ) of fall-applied PL to winter wheat via field and …

Closing yield gaps in South Asian wheat production (Bihar, India and Terai of Nepal)
Rising wheat consumption and recurring climate extremes threaten food security in the Eastern Indo-Gangetic Plain. Closing wheat yield gaps in this region through agronomic practices currently available to farmers can contribute to a more secure future in this region. In Nepal and Bihar, India, a …

Modelling atmospheric dispersal of fungal pathogens on continental scales to safeguard global wheat production
… highly virulent strains of the pathogen causing wheat stem rust has been acknowledged as a threat to global food security. In infected wheat fields, vast amounts of pathogenic fungal spores are produced that can be carried away by wind. For targeted disease surveillance and control it is …

An estimation of the economic value of irrigation water for wheat production at sable farms
… method to value water used for irrigation of wheat at sable farms. Sable farms use about 5130m^ of water per hectare of wheat during the entire growing period of wheat. Each cubic meter of water used to irrigate wheat generates an income of about ZMK 1,000 for the farmer. The financial and …

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 …

Herbicide resistance in kochia and wheat: the loss and gain of weed control tools for wheat production
… worldwide. Currently, weed control in crop production systems relies heavily on the use of chemical herbicides. While these herbicides are largely effective and very efficient, they are prone to herbicide resistance evolution in weeds. Herbicide resistance evolution is the most pressing …

Determination and modelling of energy consumption in wheat production using neural networks : "A case study in Canterbury Province, New Zealand"
… this study was to estimate energy consumption in wheat production. Energy determination can give a clear picture of farms in order to compare different farming systems and energy inputs. The second main target of this study was to develop a neural network model to simulate and predict energy use …

Analysis of wheat pricing policy in Zimbabwe
In Zimbabwe, wheat is the principal crop planted in winter occupying about 95 percent of winter planted acreage, it is also one of the most tightly regulated of the controlled crops. Even though Zimbabwe's wheat industry is well developed by regional standards, domestic production has not kept pace …

Response of wheat (Triticum Aestivum)to Vesicular Arbuscular Mycorrhiza(VAM) and Trichoderma on grain yield and uptake of phosphorous in Acidic Soils
Wheat is an important economic cereal crop used in the production of a wide range of foods and other products. However, due to low wheat production (< 1.5 ton/ha) in acidic soils, and the country’s total demand of about 240,000 metric tones as at 2010, is unable to be met. Acid soils generally …
