In order to evaluate drought resistance indices, an experiment was carried out in a randomized complete block design in three replications with thirteen bread wheat genotypes and two levels of irrigation, stressed and non stressed, at Dry land Agricultural Research Institute (DARI), Maragheh, in 2009-2010. tolerant on the basis of yield performance in stressed (ys) and non-stressed (yp) environ...
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...

introduction: nitrogen (n) is one of the most important growth-limiting nutrients for dryland wheat. mineral nitrogen or ammonium (nh4+) and nitrate (no3−) are two common forms of inorganic nitrogen that can serve as limiting factors for plant growth. nitrogen fertilization in dryland area can increase the use of soil moisture, and improve wheat yields to some extent. many researchers have been...

GRACEnet (greenhouse gas reduction through agricultural carbon enhancement network) is a new research program initiated by the Agricultural Research Service (ARS) of the United States Department of Agriculture (USDA). The primary objectives of GRACEnet are to identify and develop agricultural strategies that will enhance soil C sequestration and reduce greenhouse gas emissions and to provide a ...
Changes in agricultural land use have important implications for environmental services. Previous studies of agricultural land use futures have been published indicating large uncertainty 10 due to different model assumptions and methodologies. In this paper we present a first comprehensive comparison of global agro-economic models that have harmonized drivers of population, GDP and biophysical...
