Ryegrass is the probably the most damaging weed to winter wheat over a large part of the high rainfall area in the central, north and east Texas. Economic losses in wheat occur through reduced grain yield, quality, foreign matter, and harvest efficiency. Yield loss can exceed 90% in heavy infestations. In addition to yield reduction, reduced harvest efficiency results in lower test weight, high...

In the Great Plains of North America potential evaporation exceeds precipitation during most months of the year. About 75% of the annual precipitation is received from April through September, and is accompanied by high temperatures and low relative humidity. Dryland agriculture in the Great Plains has depended on wheat production in a wheat-fallow agroecosystem (one crop year followed by a fal...

Agriculture has a key role in greenhouse gas emissions.  As such, the present study aimed to evaluate the greenhouse gas emissions from wheat production in irrigated and rain-fed systems. The primary data were collected from 116 wheat farmers. The results showed that the total greenhouse gas emissions from wheat production in irrigated and rain-fed systems were 637.8 and 65.12 kgCO2eq, respecti...

Conventional agriculture systems of production often lead to environmental degradation, economic problems and even social conflict. The efficacy of agriculture systems conducive to the economic, environmental and social sustainability of farming operations has been demonstrated, yet the adoption of sustainable agricultural practices is not widespread. This study evaluates the barriers of sustai...

Pre-harvest prediction of winter wheat (Triticum aestivum L.) grain yield and/or protein could assist farmers in generating yield maps and reliable product marketing. This study was conducted to determine the relationship between spectral measurements (taken from Feekes growth stage 8 to physiological maturity) and grain yield and grain protein. Spectral measurements were taken using photodiode...

In the year 2009, 170 cauliflower, eggplant, endive, lettuce, pepper, potato and wheat samples from Slovene producers were analysed for pesticide residues. The samples were analysed for the presence of 214 different active compounds using three analytical methods. MRL exceedances have not been observed, which is better than the results obtained from the monitoring of pesticide residues in the p...

This study probes into the interplay of the factors operating on supply side of the wheat economy of Pakistan. The analysis is carried out to determine the performance of the agricultural policy of the country in securing a sustainable measure of self-sufficiency in food production. It is argued that, compared to the developed countries, the developing countries like Pakistan have done too litt...

Rice provides the staple food for over 60% of the world’s population. Globally 80% of rice is grown by small farmers in low income and developing nations, and in India rice farming is a key source of employment for the 60% of Indian workers still dependent on agriculture for work. Yet rice production is also an important source of greenhouse gas emissions, for example responsible for between 3 ...

Traditional indicators of protection refer to the level effect of price policies on income and ignore the stabilizing effect. We derive a measure of the real rate of protection which incorporates these dual dimensions. The income stabilizing effects of price policy protection lead to a greater level of real protection than would be measured conventionally. Without compensatory payments real pro...
