Strategic foliar nutrition with Sorbitol, Mannitol, and Boron improves physiological performance and yield in Faba beans on reclaimed sandy soil.

ABSTRACT: Under natural field stress conditions in newly reclaimed sandy soils characterized by extreme diurnal temperature fluctuations (ΔT > 20 °C, peak temperatures 42 °C), limited water retention, and moderate salinity, faba bean cultivation faces significant yield stability challenges. This study evaluated whether combined foliar applications of sugar alcohols (sorbitol, mannitol) and boron could synergistically enhance stress tolerance and yield stability in faba bean under these conditions. A two-season field experiment (2023/2024, 2024/2025) at Sadat City, Egypt, tested three cultivars (Nobaria3, Misr1, Giza717) under seven foliar treatments: control (CK, distilled water), individual applications of sorbitol (40 g L⁻¹), mannitol (40 g L⁻¹), boron (50 mg L⁻¹), and binary combinations (S + M,
