Traditional water-saving irrigation management turns on water pump in a settled interval decided by grower’s experience. The method just saves water on the back of losing yield. In order to result the problem, a kind of greenhouse efficient irrigation management system based on Evapotranspiration has been developed. The system includes greenhouse environmental monitoring subsystem, irrigation a...

one of the most important sits of sasanian period in iran from which the royal hunting plaques were recovered has been chal tarkhan of eshgh abad. there was a sasanian palace containing a considerable number of stucco representing variety of subject pointing to a deep understanding of sasanian stucco art. in spite of the researchers made by e.g. thompson and kroger on this plaques yet, there ha...

A simulation model was developed to estimate the effect of deficit irrigation upon crop yield. The model was designed to provide relative yield estimates for numerous combinations of irrigation system, crop growth and irrigation management parameters. A daily soil moisture balance was used to predict evaporation and transpiration from which crop yields were estimated. Gross irrigation water req...

Automatic irrigation systems usually conveniently protect landscape investment. While conventional irrigation systems are known to be inefficient, automated ones have the potential to optimize water usage. In fact, there is a new generation of irrigation systems that are smart in the sense that they monitor the weather, soil conditions, evaporation and plant water use, and automatically adjust ...

Irrigation systems are as old as man itself since agriculture is the foremost occupation of civilized humanity. To irrigate large areas of plants is an onerous job. In order to overcome this problem many irrigation scheduling techniques have been developed which are mainly based on monitoring the soil, crop and weather conditions. Irrigation scheduling engrosses when to irrigate and how much wa...

The purpose of this in vivo study was to investigate the antimicrobial effectiveness of 6% sodium hypochlorite, when used with the conventional irrigation technique using a 30 gauge side-vented needle, the EndoVac TM System, and the ProUltra PiezoFlow TM Ultrasonic Irrigation Needle. It was hypothesized that both the EndoVac TM system and the PiezoFlow TM Ultrasonic Irrigation Needle would remo...

-Water plays an important role in everyday’s life. Agriculture is a backbone of our country and it uses 85% of available fresh water for irrigation. Irrigation is the method of supplying the water to the plants artificially. In India, Farmers follow different irrigation systems to cultivate the crops. The different types of irrigation methods include sprinkler irrigation, drip irrigation, surfa...

We studied nutrient balance in a paddy field that had a recycling irrigation system and evaluated the effect of the irrigation system on nutrient balance during the irrigation period, from April to August 2002. Chemical fertilizer was the main input of phosphorus; the soil absorbed about 56% of it. The amount of nitrogen supplied by the irrigation system was higher than in a representative padd...
