An economic evaluation of supplemental irrigation on claypan soils
"Purpose of this study: Since irrigation is a new management practice of crop production in this area, the economic effect is not very well known. Very little information is available from actual on-the-farm records. This study was done to collect, summarize, and evaluate the cost, return, and …

Optimal Conjunctive Management of Supplemental Irrigation Reservoirs and Cropland
… groundwater supplies to provide wells for irrigation. Therefore, the establishment of reservoirs for storing rainfall and runoff water, seems to be the most likely source of irrigation water in such areas. However, the storage of runoff water for later reuse in the irrigation of crops when …

Physiological response of two turfgrass species to increasing drought and salinity stress using a line source gradient
… beneath the Las Vegas valley, as an alternative irrigation source for turfgrass. Results indicated that the aquifer could be used as a supplemental irrigation source, without any diminished turfgrass quality, if total water potentials {dollar}\rm(\Psi\sb{T}){dollar} were maintained above species …

Characterization and remediation of toxic metals in wastewater reuse for agricultural irrigation
… demand has led to the reuse of wastewaters for irrigation purposes. Left untreated, these reused wastewaters may contaminate agricultural land, plants, and thereby food products. Common contaminants include toxic metals, which are conservative within the soil-plant-water system. While …

On the Climate-Agriculture-Water Nexus at the Regional Scale
… development (expansion, intensification, irrigation) accounts for observed July-August temperature decreases (0.2-0.3 ∘C) from 1920-1949 to 1970-1999 and about 30% of precipitation increases (0.2 to 0.3 mm/day). These agriculturally driven cooling and wetting trends in the historical …

Water use of mature pecan orchards under semi-arid conditions
… and as a result most orchard crops depend on supplemental irrigation, especially in areas in South Africa, where rainfall patterns are unpredictable and sparsely distributed. Through accurate quantification or estimation of crop water use or evapotranspiration (ET), the need for supplemental …

Effect of summer and winter rotations on selected soil properties and productivity of succeeding winter chickpea (Cicer arietinum L.)
… planting at a recommended rate of 90 kg P ha-1. Supplemental irrigation was applied whenever necessary. Plots were kept weed-free throughout the growing seasons. Soil samples were collected at depths of 0–20, and 20–40 cm prior to planting (experiment I) and after harvesting (experiment II) in …
