Background: Consumer demand for organic spelt wheat has increased rapidly and production expanded into semi-arid regions, where it was not traditionally grown. Methods: Here, we report the results of a factorial field experiment designed to compare performance four varieties grown in rain-fed irrigated, conventional systems environment. Results: Irrigation resulted 2.5-fold higher grain yields,...

the effect of 10-year continuous saffron cultivation on physical and chemical properties of a silty clay loam soil was investigated in a research farm of college of agriculture, shiraz university, shiraz (52 º 33ʹ e longitude and 29º 36ʹ n latitude), iran. this farm was irrigated with different regimes (100% of saffron's potential evapotranspiration (etp), 75%etp, 50%etp) including rain fed tre...

the agriculture sector has been affected by severe drought in recent years, making development of a drought warning system for agriculture crucial. such a system can be a useful tool for policy makers and investors. this research develops a model for agricultural drought risk assessment using statistical and intelligent methods. kermanshah province, a major rain-fed region of iran, was selected...

Rain-fed food crop production is very sensitive to climate variability. The majority of Ethiopian population reliant on rain-fed seasonal agriculture, which the backbone country’s economy. objective study was investigate impact rainfall and temperature changes maize sorghum yields. data were analyzed using Mann–Kendall trend test, Sen’s slope, correlation, regression models. study’s findings de...

Drought is perhaps the manifestation of desertification, which may be because of unprecedented soil erosion, large scale deforestation and abrupt change in micro-climate thereby increasing the temperature and reducing rainfall etc., ultimately leads to fall of groundwater level and hence, loss of agricultural productivity of the land, due to lack of water resources. Since, Indian Agriculture is...
