Freshwater resources are fundamental for maintaining human health, agricultural production, economic activity as well as critical ecosystem functions. As populations and economies grow, new constraints on water resources are appearing, raising questions about limits to water availability. Such resource questions are not new. The specter of "peak oil"--a peaking and then decline in oil productio...
To investigate the effect of deficit irrigation on yield of mung bean genotypes, an experiment was conducted as a split plot in randomized complete block design (RCB) with three replications. The main plot was irrigation regime in three levels (supply of 100, 80 and 60% of crop water requirement) and subplot was genotype in five levels (VC 11-18b, VC 63-72, CN-9-5, NM 54 and 1-61-145). The resu...
background and objectives: although more than 90 percent of consumed water used in agricultural sector, water is the major limiting factor for agricultural development in iran. over the past few years increasing agricultural crop water productivity thorough deficit irrigation methods has been studied by agricultural researchers and planners. although lorestan province is one of the major produc...
A research was conducted in Fars province Agricultural Research Center in Zarghan area from 1999 to 2002 to determine the water requirement and crop coefficient of wheat, applying lysimeter. The results indicated that the water requirements of wheat were 720, 712 and 674 mm in the years of 1999-2000, 2000-2001 and 2001-2002, respectively. Using Penman-Monteith method for estimating reference ...
Water demand prediction by end-use at an appropriate spatial and temporal resolution is essential for planning water supply systems that will supply water from a diversified set of sources on a fit-for-purpose basis. Understanding seasonal, daily and sub-daily water demand including peak demand by end-uses is an essential planning requirement to implement a fit-for-purpose water supply strategy...
Swimming is frequently recommended for cardiac rehabilitation, but little is known of its physiologic consequences in ischemic heart disease. Eight males who had had a myocardial infarction 8-17 months before the study were exercised to exhaustion or angina with 10 W/min-1 ramp on a cycle ergometer in sitting and supine positions. Oxygen uptake (VO2) was continuously measured to monitor the phy...
Factor analysis is one of the multivariate statistical techniques that considers the interrelationships between apparently irrelevant variables and helps researchers to find the hidden reasons for the occurrence of an event. In order to evaluate the effects of different irrigation levels and humic acid foliar application and identify the factors affecting water use efficiencies of sesame (Sesam...
The agricultural regions are running into difficulties, which are restrictive availability of water, successive appearing draughts, and overuse of ground water resources for supplemental water requirements. As a sample which is got from the farm is sent to the laboratory for testing and the laboratory works need devices. Hence, conducting farm experiments are expensive and time consuming to opt...

in order to evaluate the effect of water deficit and different fertilizer levels on yield and some agro-morphological characteristics of moldavian balm, a split plot experiment was conducted in a randomized complete block design with three replications at the research farm of shahrekord university during 2013-2014 growing season. main factor was three levels of irrigation regimes including: 100...
