Mathematical Problems in Engineering, 2022 The pipeline combination scheme is optimized to reduce the cost of irrigation units in an economical microsprinkler system. With the standard number of segments of branch and capillary pipes as the decision variables, the lowest pipe cost per unit irrigation area as the objective function, the maximum pressure difference allowed in the system, the ...

Costs of pressurized orchard irrigation vary with system design [PDF]
California Agriculture, 1999 The costs of solid-set sprinkler and microirrigation (drip, micro-sprinkler and minisprinkler) systems are a major factor in the adoption of these irrigation technologies.

Irrigation Scheduling Methods Affect Water Use [PDF]
EDIS, 2020 Irrigation scheduling has been one of the most important management practices to improve crop production. For citrus, there are multiple options to schedule irrigation including evapotranspiration-, plant-, and soil-based.

Spatial variability of discharge and pressure in subunit of microsprinkler irrigation with used and new emitters [PDF]
Revista Ambiente & Água, 2008 This work studied in field the spatial distribution of discharge and pressure in subunit irrigated by microsprinkler, considering used and new emitters. The data were collected in 28 emission points spaced in 10 x 18 m. The mean values were submitted to normality test and also to a geostatistical analysis; the verification of the spatial dependence and

Irrigation shifts toward sprinklers, drip and microsprinklers [PDF]
California Agriculture, 1997 From 1972 to 1995, gravity irrigation (flood, furrow and so on) has decreased by about 20% on an acreage basis, while sprinkler irrigation has increased by about 8% and microirrigation, including drip and microsprinklers, has increased by about 12%. These statewide estimates exclude rice acreage and are based on surveys commissioned by the California ...

Under- and Overtree Microsprinkler Irrigation for Frost Protection of Peaches [PDF]
HortTechnology, 1993 Spring frost events reduce fruit production in the southeastern United States more than any other factor, with some losses occurring in 5 out of 7 years. Orchard heaters, wind machines, and overhead irrigation are sound methods of reducing losses, but their relatively high cost is a major deterrent for fruit growers (Castaldi, 1990)

Improved Criteria for the Design of Microsprinkler Systems to Maximize Crop Profit under Different Water Supply Scenarios [PDF]
, 2021 Population growth and increasing food demand require cropping systems that produce higher yields with less water. Microirrigation can fulfill this demand but has a high investment cost, which can be reduced with adequate irrigation design and management.

Cold Protection of Kiwifruit Plants with Trunk Wraps and Microsprinkler Irrigation [PDF]
HortScience, 1992 Own-rooted, 4-year-old kiwifruit plants [Actinidia deliciosa (A. Chev.) C.F. Liang et R. Ferguson var. deliciosa] protected by a Styrofoam insulation wrap with a water-filled pouch (Reese clip-on trunk wrap) or by microsprinkler irrigation sustained ...
