Wheat (Triticum aestivum L.) production requires a large amount of nitrogen (N) supply because growers aim to achieve high grain yield and appropriate protein content simultaneously. A comprehensive understanding the mechanisms that underpin efficient N usage at limited in wheat can facilitate development new N-saving varieties this major crop. Here, we performed comparative analysis flag leaf ...
Increasing food production to feed its rapidly growing population is a major policy goal of Pakistan. The production of traditional staples such as rice (Oryza sativa L.) and bread wheat (Triticum aestivum L.) has been intensified in many regions, but not in remote, drought-ridden areas. In these arid, marginal environments dates and their by-products are an option to complement staples given t...
This research was done aimed to investigation the effective factors on production skills of tobacco growers in Mazandaran province. This is an applied study based on descriptive-correlation method. Statistical population of this research consisted of 1500 tobacco growers of Mazandaran province, and 306 people were selected based on Morgan table. Content validity of the questionnaire was determ...
the technical, allocative and economic efficiency of wheat growers in baft, kerman province were studied to analyze the degree of farmers success in the optimun allocation of their resources and the possibilities of increasing the production based on the available resources and factors of production. sampling was based on random method, so 75 farmers were selected. the stochastic frontier produ...
The objective of this study was to evaluate the strategies for groundwater resources management, including competition groundwater pumping, optimal control in groundwater pumping, groundwater use and tax policy, water users' participation in groundwater pumping control, and cooperation among government and water user associations in Narimany plain located in Khorasan Province. Irrigation wate...
Abstract The CoAXium ® Production System includes a new herbicide-resistant wheat (AXigen ) that allows for fall and/or spring postemergence (POST) applications of quizalofop-P-ethyl (QPE) control winter annual grass weeds. As area planted with AXigen increases, so will the use QPE herbicide, and this comes an increased chance physical drift, tank contamination, or misapplication to nearby sens...
Transgenic maize engineered to express insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) has become widely adopted in U.S. agriculture. In 2009, Bt maize was planted on more than 22.2 million hectares, constituting 63% of the U.S. crop. Using statistical analysis of per capita growth rate estimates, we found that areawide suppression of the primary pest Ostrinia nubilalis (Eu...
The reform of the European Union's sugar regime caused potential decreasing beet prices. Therefore, the Speeding Up Sugar Yield (SUSY) project was initiated. At the start, a 3 × 15 target was formulated: in 2015 the national average sugar yield in the Netherlands equals 15 t/ha (60% of the sugar beet potential) and the total variable costs 15 euro/t sugar beet, aspiring a saving on total variab...
The Palouse Prairie of eastern Washington was identified in the 1997 USDA National Resources Inventory as one of the most highly erodible areas in the United States. It is estimated that 10% of the original topsoil in eastern Washington has been lost since cultivation began in the region in the late 1800s (32). Furthermore, runoff from agricultural land reduces water quality in streams and rive...
In this article we propose and solve a game-theoretic model of a rank-order tournament with private information. Using the contract settlement data from a poultry company, we estimate a fully structural model of a symmetric Nash equilibrium of this game. We show that growers’ equilibrium effort depends on four factors: the spread in piece rates between the performance brackets, the number of pl...
