poor wheat stand establishment is a major cause of yield loss, particularly in rainfed and poorly irrigated environments. seeds of eight wheat cultivars (triticum aestivum l.) including irrigated and rainfed varieties, belonging to three different climates of iran (hamedan as cold, karaj as temperate and sarpolzohab as warm climates) were primed using osmoprimig treatments through use of urea ,...

in order to compare the agronomic characteristics of developed iranian spring wheat genotypes (selective cultivars from: endemic landraces of wheat, interal hybrid wheat and international centers) and also the identifying traits affecting grain production under different concentration of iron in the soil solution, a randomized complete block design with a split-plot arrangement with 30 wheat ge...

Climate change and variability threaten the sustainability of future food production, especially in semi-arid regions where water resources are limited irrigated agriculture is widespread. Increasing temperatures will exacerbate evaporative losses increase plant needs. In this regard, higher irrigation intensities have been posited as a solution to mitigate climate impacts these regions. Here, ...

background and objectives: currently nearly 70% of the area under cultivation of a milliard hectares of the world, devoted to cereals as well as about half of the total dietary needs of people, especially in asia directly from cereals sources. factors affecting wheat quality includes the chemical, physical, qualitative and farming. since each grain products requires the use of flour with specia...

This paper assesses the changing norms of water use known as the duty of water. It is a case study in historical socio-hydrology, or more precisely the history of socio-hydrologic ideas, a line of research that is useful for interpreting and anticipating changing social values with respect to water. The duty of water is currently defined as the amount of water reasonably required to irrigate a ...
