BACKGROUND The need for reoperation or wound infection treatments between pulsatile and gravity irrigation are statistically equivalent, however, it is unclear which method maximizes operative efficiency and expeditious irrigation. In this study we set out to determine the differences in irrigation rate between these various treatment methods. METHODS This was an ex-vivo experimental laborato...

Many factors affecting irrigation model, including irrigation water volume, crop water requirement, production function of irrigation water, rainfall, soil water balance, water sensitive index in different stages of crop growth, the grain market price, irrigation water price, minimum yield, irrigation cost etc are considered. Then a multi-constraints and non-linear optimization irrigation model...

the responses of isabgol (plantago ovata forsk.) to micronutrient foliar application under low irrigation condition were investigated. the experiment was carried out in agricultural research farm of zabol university, iran, during growing season of 2007-2008. the experiment was conducted in spilt plot using randomized complete block design with four replications. three irrigation regimes defined...

Since the 1970's, a large number of individual field studies of diverse irrigation systems have been completed in Nepal. Some of these studies were undertaken by masters or doctoral students and are based on extensive periods of time in the field. Others were written on the basis of shorter periods in the field: rapid rural appraisals, brief reports, and field-site visits by expatriate advisors...

A fuzzy control irrigation system for cotton field is presented in this paper. The system is composed of host computer, slave computer controller, communication module, soil water sensors, valve controllers, and system software. A fuzzy control model is constructed to control the irrigation time and irrigation quantity for cotton filed. According to the water-required rules of different cotton ...

this study investigated the effect of sowing date and limited water allocation management for single irrigation on the grain yield of rainfed barley. the experiment was a split-split plot arranged in a randomized complete block design with three replications from 2004 to 2006 at the main station of the dryland agricultural research institute at maragheh. the treatments comprised three sowing da...

To improve agricultural water resources’ utilization, crop’s automatic, locate, time and appropriate drip irrigation is a good choice. In this paper, an automatic control drip irrigation system based on ZigBee wireless sensor network and fuzzy control would be introduced. System uses CC2430 for wireless sensor network node design, collecting soil moisture, temperature and light intensity inform...
