Research Interests / Job description
(Emeritus) Fruit tree irrigation and nutrition

 Fields of Scientific Interest:

  • Irrigation of fruit trees.
  • Modeling for consumptive use, and deficit irrigation.
  • Irrigation methods, in relation to nutrient and water use efficiency.
  • Saline and recycled water utilization.
  • Nutrition of fruit trees :
    • Fertigation, nutrient distribution in the soil.
    • Nutrient supply and demand. Estimating requirement and correcting defficiencies.
  • Foliar fertilization.
  • Effect of nutrition on fruit quality, storage properties and physiological disorders.

 Current Research Objectives:

  • Evaluating the use of recycled water for olive cultivation.
  • Validation of an irigation model for wine grapes under high evaporative demand.
  • Cultivar and rootstock selection of olive for resistance to salinity.
  • Imroving persimon fruit quality by N-K nutrition.
  • Evaluating the interaction between plant water status, crop level, fruit size and quality of apples and nectarines.
