The adaptive responses of crop genotypes and patterns of genotype x location (G x L) interaction are important to crop improvement as they are the basis for selection for specific adaptation and for elucidation of the causes of G x L interaction. Their legitimate assessment, however, requires yield data for the test genotypes for a large number of sites and over multiple years. Such data are se...

regarding increased limitations on fresh water availability in agriculture and the necessity of finding solutions for management of unconventional waters, some scenarios for using saline water were assessed for forage maize. saltmed model, as an integrated approach, can be used for a variety of irrigation systems, soil types, soil stratifications, crops, water management strategies (blending or...

this paper undertakes a preliminary evaluation of economic impact of aqua-agriculture reservoirs in golestan province with different size classes. the method of information gathering in this research has been in method census from 39 of aqua-agriculture reservoirs in 4 classes (25 ha.) that information necessary to complete questionnaire has prepared. results showed that fish fingerling proprat...

A field crop irrigation management decision-making system (CropIrri) was developed based on the soil water balance model, crop phenology model, root growth model, crop water production function, and irrigation management model. The irrigation plan is made through predicating of soil water content in root zone and daily crop water requirement using historical and forecasting weather data, measur...

Agriculture of the inland arid region in Xinjiang depends on irrigation, which forms oasis of Northwest China. The production and water use of wheat, a dominant crop there, is significantly affected by undergoing climate variability and change. The objective of this study is to quantify inter-annual variability of wheat yield and water use from 1955 to 2006. The farming systems model APSIM (Agr...
