Evaluation of Deficit Irrigation Strategies for Corn
… is critical to develop and implement efficient deficit irrigation strategies, and to predict the impacts of deficit irrigation on yield. South Dakota State University Management Software was used to simulate center pivot irrigation and com growth and yield at seven locations across the Great …

Deficit Irrigation Strategies on young orange trees (cv Tarocco Sciara)
… One way to optimise water resources is to employ deficit irrigation (DI) strategies. DI effects on some physiological characters of young orange orchards were analysed. The orchard includes 300, 4-years old, plants located at the CRA-ACM experimental farm in Lentini, Sicily (37° 20 N; 14° 53 E). …

Creeping Bentgrass, Kentucky Bluegrass and Tall Fescue Responses to Plant Growth Stimulants Under Deficit Irrigation
… Dominion blend were evaluated under deficit irrigation and upon exogenous application of plant growth stimulants (PGS), seaweed extract (SWE) + humic acid (HA), glycinebetaine (GB) and a commercial SWE product (PP). The objectives were to determine crop coefficients (K<sub>c</sub>) …

Strategies for limited and deficit irrigation to maximize on-farm profit potential in Colorado's South Platte Basin
… package of changed practices which may include: deficit irrigation, new crops, dryland crops, permanent or rotational fallowing of fields, and crop rotations. Some farmers will also consider upgraded irrigation systems as an aspect of implementing these practices. The farmer-driven optimization …

Effects of deficit irrigation frequency on plant growth, water use and physiology of Pelargonium x hortorum and tomato (Solanum lycopersicum L. cv. Ailsa Craig)
… where water is a threatened resource, altering irrigation frequency may present a viable approach to reduce water use, without any negative effect on crop yield and/or quality. However, our understanding of the physiological impact of this approach in containers in a peat based substrate is …

Towards 3D Crop Phenotyping of Above- and Belowground Grain Sorghum Plant Traits Using Airborne Mounted Multispectral Camera, TLS, and GPR Remote Sensing Technologies
… grain sorghum (Sorghum Bicolor L. Moench) under deficit irrigation. The red and white varieties of sorghum were monitored using a randomized split plot design with three levels of deficit irrigation (30%, 60%, and 100%). These plots were replicated three times for a total of 18 plots. We …

Sustainable Approaches to Enhance Water Productivity in Cucumis melo
… yield. Sustainable strategies such as grafting, deficit irrigation, and an improved understanding of plant-water relations offer potential solutions to enhance crop water productivity (CWP). This study conducted at the University of Nevada, Reno, evaluates three sustainable approaches to increase …

Water Conservation Practices for Irrigation of Turfgrass Lawns
… requirements, particularly with regards to irrigation. It is important to manage irrigation in order to maximize water conservation without significantly reducing lawn quality. A series of field and greenhouse studies were conducted to investigate how water usage might be reduced in …

Agronomic and physiological impacts of irrigation frequency on green basil (Ocimum basilicum L.)
… factor restricting agricultural production and irrigation globally, with sustainable agricultural development calling for less irrigation water use and more production per unit of water applied. Improved understanding of plant physiological responses to water stress, and the effect of irrigation …

Pre- and Postharvest Practices for Optimizing the Postharvest Quality of Cut Sunflower, Dahlia, and Delphinium
… on delphinium 'Guardian Mix' and the effects of deficit irrigation on delphinium 'Guardian Blue.' 'Guardian Mix' plants produced marketable cut stems at nitrogen rates as low as 50 mg/L. Deficit irrigation did not change vase life, stomatal conductance, or transpiration rates of delphinium …

A canal irrigation water allocation model.
… with allocation of canal water to competing crop irrigation demands. Multi-period linear programming was utilized to optimally allocate water in both time and space to maximize benefits for an irrigated farm. Irrigation scheduling, crop response and canal water delivery models were used to support …
