Overview

Randomized trial evaluates almond physiology and productivity under deficit irrigation and soil management in Mediterranean conditions, suggesting cultivar plays a critical role.

Key Points

  • This research aims to understand the physiological responses of almond trees to regulated deficit irrigation in organic farming and identify the best-performing cultivars.
  • Evaluated effects of full irrigation and regulated deficit irrigation on almonds over two growing seasons (2024–2025).
  • Conducted physiological monitoring of photosynthesis, stomatal conductance, transpiration, CO2 concentration, and water potential.
  • Compared almond cultivars (Guara, Marta, Lauranne, Marcona) under different soil management practices.
  • Cultivar Marta produced an average of 1092 kg ha−1 and Lauranne 1164 kg ha−1, significantly outperforming Guara (600 kg ha−1) and Marcona (442 kg ha−1).
  • RDI affected stem water potential and transpiration but did not severely constrain photosynthesis. Yield responses were primarily dependent on cultivar rather than irrigation strategy.
