2011 Annual Report

1a. Objectives (from AD-416)
The objective of this cooperative research project is to develop technology and methodology for efficient use of water in agricultural systems suited to dry land climates, by applying Irrigation Management Information System (IMIS) techniques.

1b. Approach (from AD-416)
Under this agreement, and in accordance with the budget agreed to by both Parties to this Agreement, the Cooperators shall: 1. As appropriate, conduct research under the Irrigation Management Information System (IMIS) project, which is part of a cooperative research project bringing together participants from Israel, Jordan, Palestine, and the United States to Improve water management by providing data for scheduling irrigation and other crop management decisions to increase irrigation efficiency in the Middle East and The United States. 2. Establish an IMIS research and extension sites to represent the important agricultural production systems in Jordan. Evapotranspiration (ET) models for several conventional and specialized crops will be evaluated for the designated sites and prioritized according to applicability criteria. Soil and plant water-status measurement instrumentation will be evaluated, adapted and integrated into the system according to the same applicability criteria. 3. Conduct collaborative regional research on measurement of crop water use and calculation of crop coefficients for key crops, such as cucumbers, peppers, and specialty crops. 4. Establish interaction with local universities, farmers, farm advisors, and extension personnel in order to implement the IMIS system to ensure wide acceptance and sustainability. 5. Establish the methodological framework to transfer the crop water requirements information received from the metrological stations to the farmers. 6. Assist in providing training to the Jordanian farmers in conservation technology such as cover crops and composting methods.

3. Progress Report
NCARE hosted the Middle East Regional Irrigation Management Information (IMIS) workshop held in November 2010 with twenty two participants representing all of the partner countries. An experiment based on meteorological station measurements was conducted in Dair Alla Experiment station where an area of 2.0 hectares surrounding the weighing Lysimeter was cultivated with onion. During this period daily measurements were taken. The results indicated that the actual Evapotranspiration (ETc) for this crop for this period in Dair Alla to be 409 mm, while the potential Evapotranspiration (ETo) was equal to 644 mm. According to the results it was possible to modify the single crop coefficient (Kc) for onion in the Jordan Valley Kc values at 0.5 for the initial stage, 0.95 for the developing stage, and 0.4 for the final growth stage). A second experiment was conducted in Dair Alla Experiment station on Green Beans from March 2011 through May 20011, with daily measurements taken. The results indicated that the actual ETc for this crop for this period in Dair Alla to be about 231mm, while the potential ETo was equal to 300mm. Kc values were also estimated and modified for this crop. A demonstration site experiment for eggplant was conducted in Dair Alla Regional Center, based on meteorological station measurements to determine irrigation indicator. This demonstration site was planted with eggplant on 12 April 2011 and is on-going. Results will be provided after harvesting by December 2011. Overall progress in this project included increased scientific cooperation among American, Israeli, Jordanian and Palestinian scientists; establishment of an agricultural Meteorological station network with an internet site,; improved Knowledge of crop water use for several crops in the region; and continued plans for future collaboration on the pressing water issues of the region.
