Irrigation and Fertilizer Management

Improved irrigation strategies for alfalfa production in California

Principal Investigator: Khaled Bali, UC ANR Specialist, 559-646-6541, kmbali@ucanr.edu

Develop and improve irrigation strategies to increase water use efficiency in alfalfa production in California across different soil and climatic conditions.

Best nitrogen and irrigation management practices in California low desert carrots

Principal Investigator: Aliasghar Montazar, UCCE Imperial County, 442-265-7707, amontazar@ucanr.edu

The project aims to develop knowledge and information on improving and promoting adaptation of management practices that optimize N and irrigation water use efficiency in California low desert carrots.

Olive production practices in the Imperial Valley

Principal Investigator: Khaled Bali, UC ANR Specialist, 559-646-6541, kmbali@ucanr.edu

The objective of this research is to study the efficiency and the economic feasibility of various olive production practices in the Imperial Valley with emphases on water use efficiency and the possibility of the reuse of surface and subsurface drainage waters to supplement crop water needs.

Automation of surface irrigation systems in the Imperial Valley.

Principal Investigator: Khaled Bali, UC ANR Specialist, 559-646-6541, kmbali@ucanr.edu

This project will demonstrate the potential use of innovative automation technology in water conservation to increase irrigation efficiency and demonstrate the use of this technology to growers in the Imperial Valley.

Evaluation of water management techniques and fertilizer rates in onion production in California low desert areas

Principal Investigator: Jairo Diaz, UC ANR DREC, 760-791-0521, jdiazr@ucanr.edu

The main goal of this project is to evaluate different water management techniques and fertilizer rates in onion production in arid regions.

Improving water use efficiency in alfalfa forage production through sub-surface drip irrigation and optimal irrigation water management practices.

Principal Investigator: Aliasghar Montazar, UCCE Imperial County, 442-265-7707, amontazar@ucanr.edu

This study aims to initiate a field experiment at UC Desert Research and Extension Center to improve the efficiency of water-use in alfalfa systems via sub-surface drip irrigation (SDI), and to identify and evaluate the technical and economic viability of deficit irrigation management practices that can optimize alfalfa forage production while conserving water in the Imperial Valley.

Evaluation of drip irrigation in organic spinach production and downy mildew management

Principal Investigator: Aliasghar Montazar, UCCE Imperial County, 442-265-7707, amontazar@ucanr.edu

This project aims to evaluate the viability of adapting drip irrigation for organic spinach production compared with sprinkler irrigation, and to assess the impact of drip irrigation on the management of spinach downy mildew in the Imperial Valley.
