Objectives

  1. Evaluation of the effects of the irrigation water quality, fertigation and RDI strategies, using multi-criteria analysis (production, fruit quality, fruit diseases, WUE, etc.)
  2. Development of the farm simulator including irrigation strategy and practices
  3. Integration of the decision rules and crop models into the farm simulator
  4. Analysis and evaluation of the simulation outputs

Description of work

(Task 7.1) In-situ valuation of the effects of different RDI practices, on water use efficiency, fruit quality and safety (months: 13-36).

The idea is to test in situ (growers’ orchards) different irrigation decision rules. The success of technical innovations implies to integrate in the process the field actors as soon as possible, so that the growers and partners of extension services will be active participants in this work. The interrelation with the previous WPs is clear. As a fact, the experimental (WP2, WP3, WP4) and modelling (WP5, WP6) activities will be necessary for the design of irrigation strategies, while WP11 (development of Irrigation Best Management Practices) will only be possible after testing different RDI strategies, and their posterior validation.

(Task 7.2) Simulation of the effects of RDI practices on farm functioning using a farm simulator (months: 25-36)

Another way to test the efficiency of a given RDI strategy is to use farm functioning simulators based on soil and crop models developed in WP5 and WP6. On the one hand, the simulation model will be used to analyse the impact of changes in irrigation strategies, especially the consequences of periodic and controlled water deficits. On the other hand, the comparison of the farm simulation results and the actual farm situation will be necessary to validate the soil and crop models in each crop and environment considered.

For each of the crop species under study, one or several local pilot sites will be selected. The site selection will be defined in function of the possibility to carry out in optimal conditions the field experimentations required for the validation of a given strategy. In most cases, the proximity and involvement of growers and/or SME dedicated to irrigation control and engineering will ensure a close link with the tasks defined in WP8, WP9 and WP11.


Deliverables:

D31: Validation and evaluation of the simulator with probable feed-back effects on models. Second year (months: 13- 24)

D49: Validation and evaluation of the simulator with probable feed-back effects on models. Second year(:months: 25-36)

D64: Synthesis Report on the evaluation of soil and fruit quality models developed in the project (Month 36).


Milestonesand expected result:

Milestones: M7.1.Month 12: The basic knowledge about the agronomic response to different orchard irrigation strategies should be sufficiently documented for implementing the yield and quality models into the farm simulator. M7.2.Month 24: The irrigation decision rules should be available for their integration in the simulator.

Results: The results obtained in WP7 are necessary steps that will allow improving the elaboration of the Irrigation Best Management Practices (WP11), for each crop and location. The proposals and rules contained in the BMPs will be established and validated through the information and knowledge supplied by both the field experiments and the farm simulator outputs. There is a clear and strong feed-back relationship between WP7 and WP11.
