Online Water Scheduling Software

The WATERIGHT site was developed by the Center for Irrigation Technology at California State University, Fresno with significant support from the US Bureau of Reclamation.  The website is designed to be a multi-function, educational resource for irrigation water management. The site is designed for three audiences: homeowners, commercial turf growers, and agriculture. WATERIGHT allows growers…

How Shade & Moisture Affect Weeds and the Development of Alternate Herbicides

Horseweed (Conyza Canadensis), hairy fleabane (Conyza bonariensis), and junglerice (Echinochloa colona) are problematic weeds in the perennial cropping systems of California. This problem has been growing due to populations that have become resistant to the commonly used herbicide glyphosate and glyphosate + paraquat. Two alternative herbicides have been identified in perennial cropping systems: sethoxydim and…

Grower Survey

The Center for Irrigation Technology at Fresno State is conducting a grower survey to determine the current level of water management technology used to assist in developing irrigation schedules.  The purpose of this study is to identify technology and/or services that improve water and energy efficiency (costs).  All of your responses will remain anonymous.  The…

Advanced Pumping Efficiency Program (APEP) 

The Center for Irrigation Technology is involved in more than just irrigation product testing, certification and applied research. Since 2002, CIT has managed the Advanced Pumping Efficiency Program (APEP) for Pacific Gas and Electric Company. APEP is an incentive program intended to improve overall pumping efficiency and encourage energy conservation in California. The program offers…

Measuring and Monitoring Nitrogen Dynamics

Groundwater pollution due to agricultural practices is a prevalent issue in irrigated areas all over the world.  It is becoming increasingly important in regions of California where contamination is high.  Efforts to control this problem are exemplified in Section 83002.5 of Senate Bill SBX2-1 that defines a mission to “improve understanding of the causes of…

Advancing Mechanized Tree Fruit Picking Technology

In California fruits such as citrus, pears, peaches, plums, and apricots are almost all picked by hand.  The goal of this project was to develop a prototype end-effector for mechanized tree fruit harvesting applications.  With labor costs rising, growers have been turning to mechanized shakers, however, this can cause damage to the trees.  The availability…
