A GIS and remote sensing-based decision support tool called SAMZ-Desert was developed for management zones (MZs) delineation of a total 6852 fields in the Imperial County region southern California using Landsat-8 NDVI data acquired on 27/4 2018. In addition, number 11 cloud-free images 2018–2020 were statistically analyzed to determine extent within-field variability temporal stability MZs at regional level. majority (approx. 37%) had four as an optimum region, which could explain>85%...

There is a lack of information on the reliability smart soil moisture sensor-based irrigation controllers for autonomous urban landscape management using recycled water where conservation required, which main objective this study. A three-year turfgrass research trial (2019–2021) tertiary-treated (mean EC = 1.18 dS/m, pH 7.5) was conducted in Irvine, California, USA. total 12 treatments were designed, including six moisture-based thresholds (for triggering and terminating events) × two...

Research-based information regarding the accuracy and reliability of smart irrigation controllers for autonomous landscape water conservation is limited in central California. A two-year research trial (2018–2019) was conducted Parlier, California, to study response hybrid bermudagrass tall fescue varying scenarios (irrigation levels frequency) autonomously applied using a Weathermatic ET-based controller. The turfgrass species treatments visually assessed rated. In addition, functions...

Abstract Purple nutsedge ( Cyperus rotundus L.) poses a significant challenge to Florida tomato Solanum lycopersicum producers due its ability puncture plastic mulch, resilient tubers, and rapid rhizome proliferation. Preemergence herbicides effectively suppress purple in tomatoes under mulch. Although the impact of co‐application with fertilizers has been studied row crops, potential vegetable plasticulture systems remains unexplored. This study aimed evaluate effectiveness crop safety...

High wheat ( Triticum aestivum L.) grain yield and desirable quality must be considered to avoid market price penalty. Wheat classes genotypes may respond differently agronomic management environmental conditions. Our goal was characterize the yield, protein, test weight, falling number of four hard red soft white spring cultivars randomized within five N levels over contrasting environments (rainfed irrigated) in northwestern Montana. One‐third reduction from 2016 2017 attributed heat...

Highlights Empirical CWSI was developed for 'Westcoaster' tall fescue and ‘Tifgreen’ hybrid bermudagrass. The canopy temperature of both species monitored under multiple irrigation scenarios. Deficit might reduce the cooling benefits irrigated urban lawns. Abstract. Canopy provides valuable information efficient management detecting drought injury in a fast non-destructive way. It also helps quantify trade-offs between water conservation benefit landscape, critical issue semiarid inland...

As the drought conditions persist in California and water continues to become less available, development of methods reduce inputs is extremely important. Therefore, improving irrigation use efficiency developing conservation strategies crucial for maintaining urban green infrastructure. This two-year field project (2018–2019) focused on application optical thermal remote sensing turfgrass management central California. We monitored response hybrid bermudagrass tall fescue varying...

Developing water conservation strategies for urban landscape groundcovers grown in hot and dry summers like inland Southern California, USA, is crucial because they are one of the largest residential users. A 2-year (2020–21) study was conducted Riverside, CA, to assess effect irrigation rates on growth as evaluated by visual quality ratings (VR) normalized difference vegetation index (NDVI). Relationships between VR NDVI were also established obtain minimum threshold values each...

Abstract This study aims to evaluate the efficacy of simple linear, multiple, and robust regression methods predict fall‐harvested alfalfa ( Medicago sativa L.) yield using unmanned aerial vehicle (UAV)‐acquired multispectral thermal images. Four fields in southern California were selected, a composite dataset containing 180 ground truth sampling points was formed build test performance models. The UAV flown September 2020, 5–29 days before data collection. A total nine crop indices, canopy...

Identifying the irrigation-induced cooling effects from a particular plant species used for urban groundcovers while optimizing rates of irrigation applications is important in regions with hot and dry summers. A 2-year (2020–21) study was conducted Riverside, CA, USA, to evaluate effect on canopy temperature dynamics 10 groundcovers. Four reference evapotranspiration (ET o )-based treatments (20%, 40%, 60%, 80% ET ) were laid randomized complete block design replicated three times. The...

Core Ideas No inverse relation existed between grain yield and protein when N > 100 kg ha −1 for Egan. An relationship in Egan was only evident at a very low level. also with year, but remained premium level as long . Grain limited via reduced productive tillers number on drought year. Wheat ( Triticum aestivum L.) cultivars Gpc‐B1 gene are known to achieve high protein, which may reduce the input achieving quality. Our objectives were to: (i) determine minimum ‘Egan’ wheat varying...

Highlights A turfgrass water response function was developed for 'Westcoaster' tall fescue. The Weathermatic smart controller demonstrated reliable estimations of reference evapotranspiration. Restricting irrigation frequency did not yield savings or lead to improvements in quality. Abstract. Efficient landscape is an important conservation strategy and reduces strain on limited resources inland Southern California. three-year field trial conducted Riverside, California, evaluate the fescue...
