PRE2023-Evaluación agronómica de los nuevos sistemas productivos del almendro (PID2022-138451OB-I00)

We are searching for a skilled and motivated student to pursue her/his Ph.D. at IAS-CSIC (Cordoba, Spain) on the agronomical evaluation of new almond plantation systems, with a particular emphasis on water use and optimal management strategies in case of water restrictions. Almond production has undergone significant changes in the last 20 years. The traditional almond production systems, under rainfed and marginal areas, evolved towards intensive, irrigated, more productive plantations that have been the object of intense research and are currently well understood. Similarly to the olive tree, systems are now evolving towards super-high densities, generating plantations in hedgerows. The structure of such orchards differs from intensive systems, which can lead to differences in tree size, potential productivity, and the ability to absorb water. The working hypothesis of this proposal is that the change in the production system produces a shift in crop productivity and water needs. In addition, this change can lead to differences in the relationship between tree size, crop load, and yield, affecting water relations and the response to deficit irrigation. The candidate will pursue the Ph.D. in a multidisciplinary team and acquire skills in assessing crop water needs and water use at the field level and on the effect of deficit irrigation strategies in almond plantations. Candidates are expected to work autonomously with a well-organized work style and time management.
