Plastic mulch and drip irrigation are commonly used in high intensity vegetable production regions such as Florida. Drip irrigation can be much more efficient than sprinkler irrigation since only the root zone of the cropped area is irrigated. However, improper irrigation management can lead to wasted water and leaching of soluble chemicals such as nitrate. In this project, several irrigation t...

in the country, reducing water resources and increasing water losses in the various methods of surface irrigation, has increased attention, super drip irrigation method, especially drip tape irrigation. one of the techniques are used in cultivation of early sweet corn, the use of plastic mulch. using this technique, the reserve temperature conditions for plant growth and early maturity, resulti...

Estimation of field crop evapotranspiration (ETc) and its partitioning into evaporation and transpiration, are of great importance in hydrological modeling and agricultural water management. In this study, we used a dual crop coefficient model SIMDualKc to estimate the actual crop evapotranspiration (ETc act) and the basal crop coefficients over a cotton field in Northwestern China. A two-year ...

survivorship of the immature stage of anopheles culicifacies in damar district were studied through sampling larval and pupal stages from stream bed pools and rice fields during may and august 1993. the duration of each larval instar and the pupal stage was also determined in the laboratory for preparing the survivorship curves and the construction of the life tables. mortality from egg to adul...

During 2015, vines receiving season-long drip irrigation delivered into the lower root zone via hard plastic tubes yielded 70 % of commercial production while receiving only 15% of the water as the vines receiving full commercial rates of surface drip irrigation. Vines receiving direct root-zone (DRZ) irrigation at rates reduced to 60, 30, and 15% of commercial drip irrigation (DI) produced ind...

The practice of breast-pocket irrigation with various antibiotic solutions is supported by good literature and extensive clinical practice among most plastic surgeons. Unfortunately, recent restrictions on the use of Betadine (povidone-iodine) for breast-pocket irrigation have left many plastic surgeons confused regarding their surgical protocol for aesthetic and reconstructive breast surgery. ...

Demand for and availability of blueberries has increased substantially over recent years, driven in part by their health-promoting properties. Three blueberry varieties ('Rocío', V2, and V3) were grown under two cultivation systems (open-field and plastic tunnels) and subjected to two irrigations regimes (100% and 80% of crop evapotranspiration) in two consecutive years (2011-2012). They were e...

This paper is devoted to the practical real-time application of anew fuzzy gain scheduling control scheme to amulti-pool open irrigation canal prototype. This control scheme successfully regulates ihe downstream level of three pools of ihe prototype canal in response to the inflow rate variations. The scheme combines functionai iiizzy logic with gain scheduling.

research on crop response to deficit irrigation is important to reduce agriculture water use in areas where water is limited resource. using drought resistant landraces with irrigation scheduling based on phenological stages in semi-arid and arid regions may provide an opportunity to optimize irrigation efficiency and water savings in these regions. in order to evaluate of yield and yield compo...
