In Washington, over fifty percent of the wheat produced under rainfed conditions receives less than 300 mm of annual precipitation. Hence, a winter wheat-summer fallow cropping system has been established to obtain adequate moisture for winter wheat production. Current tilled fallow systems receive significant soil erosion through both wind and water. As a result, no-till chemical fallow system...

abstract:background and objectivesenvironmental is one of the most important components of global macro policies, therefore, one of the main prerequisite of many activities in macro level is compatibility with environment. environmental pollution is one of the most significant challenges that is faced by human society in 21st century. agriculture sector compare to the other other sectors of eco...

information is available on their effect on year-toyear variability. Effects of year-to-year variability in agricultural production systems There have been several attempts to analyze what have always been a concern, but few studies are conducted for a long effect these different aspects of management may have enough period of time where management system evaluations and assessments can be made...

This study examined the performance and future predictions for the Middle East produced by 18 global climate models participating in the Intergovernmental Panel on Climate Change Fourth Assessment Report. Under the Special Report on Emission Scenarios A2 emissions scenario the models predict an overall temperature increase of ∼1.4 K by mid-century, increasing to almost 4 K by late-century for t...

In Mediterranean cropping systems, it is important to utilize marginal lands for the cultivation of non-food crops. Spontaneous thistle genera such as Cynara cardunculus L. and Onopordum tauricum Willd. are native southern Europe. Previous research has focused on their spontaneous growth in environment or ability supply biofuel. The aim this study was identify effect two different planting dens...

The study aimed to estimate the level of yield gaps maize in major producing areas, point out causes farmers’ fields, and identify opportunities existing through management practices production Central Java. This is strategy for closing achieve food self-sufficiency agricultural land. Methods estimates should cover data sources on physical conditions (weather soil), practices, smallholder shape...

khorram was primarily received as an introduction barley for low rainfall area- cold winter (lra-cw) with the pedigree of sfa02/3/rm1508/pro//w12269/4/hml-02 arabiabiad//er/apmicb92-0926-0ap-2ap-0ap from international center for agricultural research in the dry areas in the 2002-2003 cropping season. khorram cultivar was tested in the preliminary, advance yield trial and uniform regional yield ...

The results of two field trials to determine the effect of ratoon stunting disease on the growth and yield of some widely grown and newly released sugarcane varieties are described. In the plant crop of a trial grown under full irrigation, the greatest reductions in yields of cane and sugar among six varieties, approximately 15%, occurred in N 14 and NC0376. In the first ratoon, the greatest re...

In this study, we aimed to improve rice farmers’ productivity and profitability in rainfed lowlands through appropriate crop nutrient management by closing the yield gap during dry season of Indonesia. The Integrated Crop Management package, involving recommended practices (RP) from Indonesian Agency for Agricultural Research Development (IAARD), were compared current at ten farmer-participator...
