One of the most important componenets of water management in farms is estimating crops’ exact amount of evapotranspiration (water need). The FAO-Penman-Montheis (FPM) method is a standard method to evaluate other techniques which are used for easy calculation of potential evapotranspiration, when lysimeter datasheets are not available. This study was carried out based on 18 years’ climatic dat...
To evaluate effect of different irrigation regimes and mycorrhizal fungi on the growth and yield of mungbean NM92 [Vigna radiata (L.) Wilczk], a field experiment was conducted in split plot arrangements using randomized complete block design (Irrigation after 50, 100, 150 and 200 mm evaporation from pan class A as main plots and mycorrhiza species, Glomus mosseae, G. intraradices and a non-inoc...
The increasing cultivation of corn in Ahwaz and the direct relation between the increase of the summer corn yield and its perfect irrigation in sowing period all together have made the research regarding this crop necessary. Deciding over the suitable irrigation scheduling of corn (hybrid SC.704) in summer by utilization of class A evaporation pan is the focal point of this research. Accordingl...

The Ord River Irrigation Area (ORIA) is located within northern Western Australia near the Northern Territory border. Since the beginning of irrigated agriculture in the ORIA the groundwater levels have been continuously rising and are now close to the soil surface in some parts of ORIA in northern Western Australia. The groundwater is now saline throughout most of the ORIA and soil salinity ri...
Limited information is available on water and nitrogen (N) management of sugarcane (Saccharum officinarum L.) in Khuzestan, southwestern Iran, where this crop is currently and extensively grown under heavy irrigation and N fertilization. Therefore, a field experiment was conducted from September 2000 to March 2002 at the Research Department of Karoon Agro-industry in Khuzestan to determine the ...
This guide to estimating daily and monthly actual, potential, reference crop and pan evaporation covers topics that are of interest to researchers, consulting hydrologists and practicing engineers. Topics include estimating actual evaporation from deep lakes and from farm dams and for catchment water balance studies, estimating potential evaporation as input to rainfall-runoff models, and refer...
deficit irrigation is an essential optimization method for water consumption in irrigated lands. in order to investigate the effects of deficit irrigation on growth, yield and quality traits of two tomato (lycopersicon esculentum mill.) cultivars a factorial layout based on randomized complete block design with three replications was conducted in agricultural research station of miandoab during...
Quantitative traits and the response of 20 genotypes of soybean to water deficit stress were evaluated at Agricultural Research Station of Gorgan in 2010 and 2011. Therefore, 3 separate experiments were conducted, each experiment as randomized complete block design, in 3 replications. In the first experiment, all soybean genotypes were irrigated based on 50 mm evaporation from evaporation pan...
