The tillage-based winter wheat (Triticum aestivum L.)-summer fallow (WW-SF) cropping system has dominated dryland farming in the Pacific Northwest USA for 125 years. We conducted a large-scale multidisciplinary 8-year study of annual (i.e., no summer fallow) no-till cropping systems as an alternative to WW-SF. Soft white and hard white classes of winter and spring wheat, spring barley (Hordeum ...

Wheat is widely grown in Iran as a staple food; therefore, the government there encourages farmers to produce wheat (a common agricultural enterprise) by increasing farm productivity and efficiency. The study compares the efficiency of wheat production for dryland (low input) and irrigated (high input) systems across Iranian provinces by using Data Envelopment Analysis (DEA). The average techni...

this study investigated the effect of sowing date and limited water allocation management for single irrigation on the grain yield of rainfed barley. the experiment was a split-split plot arranged in a randomized complete block design with three replications from 2004 to 2006 at the main station of the dryland agricultural research institute at maragheh. the treatments comprised three sowing da...

In many crop producing areas of the world there are reports of yield decline and loss of productive potential in soils. Little is known about the long term effects of sugarcane monocropping on changes in physical, chemical and biological properties of soils. The aim of this study was to quantify the physical and chemical condition of soils under sugarcane production in northern Kwazulu-Natal, a...

Background. Cardiac rehabilitation program is aimed at reducing secondary risk factors and improving function in patients undergoing coronary artery bypass grafting run which ultimately may delay or reduce mortality in patients. A major component of cardiac rehabilitation program is exercise. Objective(s). This study is aimed at evaluating the effect of aquatic and dryland training on Perox...

In this study, we extend a model of daily dryland dynamics by parameterizing a modified version of a minimalistic annual model to examine how the statistical structure of annual rainfall and grazing intensity interact to influence dryland vegetation. With a Monte Carlo approach, an ensemble outcome provides a statistical description of likely dryland vegetation dynamics responding to variations...
