Traditionally, we irrigate using overhead sprinklers and/or flood irrigation. However, these methods can be wasteful, and so a way to conserve and still have a healthy garden is to use drip irrigation. It can reduce water use by up to about 50%. This fact sheet reviews water recommendations for growing vegetables.

The American lawn is our nation’s single largest irrigated “crop” (Lindsey, 2005). In Utah, roughly 65% of our drinking water is applied to residential and commercial landscapes (Center for Water Efficient Landscaping, 2020). Landscapes are typically overwatered, which is why residential and commercial landscape watering is estimated to be one of the largest sources of potential water conservation in the urban setting (Endter-Wada et al., 2008). Plant materials also provide many environmental benefits, such as erosion control, water filtration, and temperature reduction. Knowing how much water to apply to the landscape can be a challenge and is one reason many …
Water Requirements Of ‘Meyer’ Zoysiagrass For Survival And Recovery After Prolonged Drought, Mu Hong, Dale Bremer, Steve Keeley
Water Requirements Of ‘Meyer’ Zoysiagrass For Survival And Recovery After Prolonged Drought, Mu Hong, Dale Bremer, Steve Keeley
Kansas Agricultural Experiment Station Research Reports
Water restrictions on irrigation are generally not science-based and may cause irreversible damage to turfgrass or inadvertently waste water. The objectives of our study were to evaluate effects of minimum water applications to ‘Meyer’ zoysiagrass (Zoysia japonicaSteud.) on 1) turfgrass performance during prolonged dry downs; and 2) survival and recovery thereafter. Zoysiagrass was watered with 0, 5, 10, 15, 20, 25, and 30% reference evapotranspiration (ET) replacement for two months in two consecutive summers under an automated rainout shelter (excluded all rainfall) near Manhattan, KS. Results indicated that irrigation at 20 to 30% ET slowed the decline in …
Performance And Recovery Of Turfgrasses Subjected To Drought And Traffic Stresses, R. Braun, D. Bremer, J. Hoyle, N. Bloedow
Performance And Recovery Of Turfgrasses Subjected To Drought And Traffic Stresses, R. Braun, D. Bremer, J. Hoyle, N. Bloedow
Kansas Agricultural Experiment Station Research Reports
This study is an effort to determine effects of drought and traffic in turfgrasses. During a 41-day summer drought in 2015 and 2016, warm-season (C4) grasses were more affected by traffic than cool-season (C3) grasses when percent green cover and turf quality were measured. This was because the non-trafficked plots in C4 grasses maintained higher percent green cover and turf quality throughout the drought due to better drought-stress tolerance than the C3 grasses. Regardless of traffic treatment or mowing height, C4 grasses maintained higher percent green cover and visual turf quality than C3 grasses during drought and recovery periods. There …

Capillary wicks can improve health and performance of container plants. Plants in hanging baskets benefit from steady and very efficient water supply from a reservoir.
Effects Of Home Value, Home Age, And Lot Size On Lawn Watering Practices Of Residential Homeowners, D. Bremer, S. Keeley, A. Jager
Effects Of Home Value, Home Age, And Lot Size On Lawn Watering Practices Of Residential Homeowners, D. Bremer, S. Keeley, A. Jager
Kansas Agricultural Experiment Station Research Reports
Lawn care and lawn watering practices of residential homeowners were significantly affected by home value and home age, but lot size was less a factor.
Simulated Effects Of Dynamic Row Spacing On Energy And Water Conservation In Semi-Arid Central California Greenhouses, A. Moya, T. Mehlitz, Ilhami Yildiz, S. F. Kelly, C. Hardin
Simulated Effects Of Dynamic Row Spacing On Energy And Water Conservation In Semi-Arid Central California Greenhouses, A. Moya, T. Mehlitz, Ilhami Yildiz, S. F. Kelly, C. Hardin
BioResource and Agricultural Engineering
Considerable effort is expended to conserve energy and water in current greenhouse systems, and look for alternative energy sources, especially passive heating and cooling strategies. Proper environmental management systems can significantly change the energy and moisture dynamics of greenhouse production systems. In this study, specifically, influences of dynamic row spacing on energy and water conservation were investigated. A dynamic computer simulation model was used to compare different row spacings, plant heights, and leaf dimensions to draw a conclusion about energy and water conservation. The results showed that using smaller spacings between cucumber crop rows (for instance, 0.5 m instead of …

Simulated Performance Of A Renewable Energy Technology – Heat Pump Systems In Semi-Arid California Greenhouses, C. Hardin, T. Mehlitz, Ilhami Yildiz, S. F. Kelly
BioResource and Agricultural Engineering
In addition to the labor, energy and water consumption are the two main cost drivers in current greenhouse systems. Consequently, considerable effort is expended to conserve energy and water, and look for alternative energy sources, especially environmentally friendly renewable energy sources and technologies. Greenhouses in hot and arid regions also require large quantities of water for irrigation. Using proper technologies and environmental management systems can significantly change the energy and moisture dynamics of greenhouse production systems. This study aims to focus on reducing natural gas, electricity, and water consumption in semi-arid California greenhouses introducing renewable energy heat pump technologies to …

Greenhouses in hot and arid regions also require large quantities of water for irrigation. Proper environmental management systems can significantly change the energy and moisture dynamics of greenhouse production systems.

Simulated Effects Of Various Environmental Management Practices On Water Consumption In Open And Confined Greenhouse Systems, Ilhami Yildiz, D. P. Stombaugh
BioResource and Agricultural Engineering
The objective of this study was to evaluate the effects of relative humidity, light management, minimum ventilation rates, CO2 enrichment and canopy size on water consumption in three different greenhouse systems (conventional, open heat pump, and confined heat pump) in winter, spring, and summer months. Using different relative humidity set points resulted in almost the same relative humidity regimes within the confined greenhouse system, resulting in similar transpiration rates. No difference was observed in transpiration rates in the open system in winter either, because the inside relative humidity levels never reached the 70% and 80% set points. Some differences …

Simulated Performances Of A Heat Pump System For Energy And Water Conservation In Open And Confined Greenhouse Systems, Ilhami Yildiz, D. P. Stombaugh
BioResource and Agricultural Engineering
The purpose of this study was to determine and compare the performances of conventional and heat pump systems for energy and water conservation in open and confined greenhouse systems. Conventional gas furnaces and evaporative cooling, respectively, provided heating and cooling in the conventional system. In the heat pump systems, gas-fired heat pump units provided both heating and cooling. The greenhouse with heat pump units also had an option to be operated as a completely confined system, using one of the heat pump units as a dehumidifier. Average energy consumption in winter was 56.9, 23.5, and 11.3 MJ/day.m² in the conventional, …
