Irrigated crops are produced on 645,000 ha in east-central Washington and northcentral Oregon (1). Approximately 70% of this cropland is irrigated with water diverted from rivers, while water for the remaining hectares is pumped from deep wells. Much of the irrigated cropland is found in areas of less than 200 mm annual precipitation, where dryland farming is difficult or impossible. Wind erosi...

Almost half of the world’s vineyards are in the EU and the EU produces around 60% of the world’s wine. The EU is also the world’s most regulated wine market. In 2007, the European Union decided on a major reform of its wine policy, the so-called Common Market Organization (CMO) for wine. A crucial element was the abolishment of a system of planting rights to regulate planting of vineyards in th...

From Jan 12th to Feb 12th 2008, the most severity cold chilling and freeze injury weather took place during the last 50 years in the southern of China. Sugar-cane was suffered injury severity. However, the losing of sugar-cane which it was aroused by this weather disaster had not been exactitude evaluated till on Apr 1st, 2008. It was not only affected the sugar-cane ordinary harvesting and cru...

A multi-year experiment was conducted to compare the effects of conservation tillage (no-till and ridge-till) with conventional plow tillage on organic C, N, and resin-extractable P in an alkaline semi-arid subtropical soil (Hidalgo sandy clay loam, a fine-loamy, mixed, hyperthermic Typic Calciustoll) at Weslaco, TX (26890N 978570W). Tillage comparisons were established on irrigated plots in 19...

rotation is also more effective in preventing deep leaching of nitrate N than continuous corn (Katupitiya et al., Reduced tillage, including no-till, and crop rotation are common 1997; Varvel and Peterson, 1990). Reduced stress from practices for corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] production in the Midwest. Benefits of no-till vary with latitude pests may be one of the reas...

Bed planted wheat systems offer a new alternative for the traditional wheat producer to provide opportunities for crop rotation, more efficient use of water, and new techniques of nutrient management. This study was conducted to determine if planting winter wheat (Triticum aestivum L.) in Oklahoma on raised beds can maintain grain yields while providing more options in the cropping system. Expe...
