UC ANR research on watermelon grafting helps growers produce 15-20% more watermelons while using 25-40% fewer plants than the traditional system under the same amount of water and fertilizers, contributing to economic prosperity for the agricultural sector.
The Issue
As the statewide water scarcity and rising inflation hit the California agriculture, food production with reduced inputs while maintaining productivity and controlling production cost heighten the necessity of using environmentally-sustainable farming practices. For watermelon growers, grafting, a thousand-year-old...

UC ANR research helps Southern California farmers conserve water by an average of 15% and encourages others to make region-specific crop management and irrigation decisions, contributing to UC ANR's public value of protecting California's natural resources.
The Issue
Water scarcity will become a more significant concern in the Colorado River Basin due to altered weather patterns and multi-year droughts. Knowledge of the evapotranspiration (ET) of crops produced in Southern California will be critical to better managing limited water resources. Accurate information on crop water use and crop coefficient (Kc) is an immediate need for on-farm water conservation...

UC ANR research on drip irrigation shows potential to reduce downy mildew incidence while improving water quality and resource-use efficiency, contributing to increased water-use efficiency and improved food safety.
The Issue
Spinach is a leafy green quick-maturing, cool-season vegetable crop. Downy mildew on spinach is a widespread and very destructive disease in California. It is the most significant disease in spinach production, causing crop losses in all areas where spinach is produced. Most conventional and organic spinach fields are irrigated by solid-set or hand-move sprinklers. However, overhead irrigation may contribute to the speed and severity of downy mildew...

Agricultural clientele utilize Extension information to inform irrigation management decisions, potentially improving water use efficiency and protecting California's water resources.
The Issue
For farmers to grow high-yielding and good quality crops and be good stewards of our finite water resources, they need to know how much water is used by their crop and how much to refill the soil with irrigation. Weather conditions and the crop's life stage determine the water use, also known as crop evapotranspiration (ET). When farmers have accurate crop ET information available, they can more closely apply the appropriate amount of water at the right time and grow more and better quality food...
