Phosphorus (P) is essential for crop growth, but its complex behavior in tropical soils necessitates alternative management strategies, such as foliar supplementation. Foliar-applied nutrients act biostimulants, enhancing stress tolerance and plant productivity. This study assessed the physiological responses of soybean to application soluble monoammonium phosphate (MAP; at a rate 5 kg ha−1 each application) different phenological stages (two during vegetative V4 V6 two reproductive R1 R3 or all four stages) across growing seasons field conditions. Key parameters analyzed included leaf nutrient content, photosynthetic pigments, Rubisco activity, carbohydrate gas exchange (photosynthetic rate, stomatal conductance, transpiration, water use efficiency, carboxylation efficiency), oxidative markers, productivity indicators (100-grain weight grain yield). MAP improved parameters, particularly R3. Total chlorophyll increased by 29.2% 30.0% when applied stages, while net rose 15.8% 18.4%, respectively. Water efficiency 20.0% indicators, H2O2 levels, decreased. activity most (46.0%) (59.9%). Grain yield was highest with spread (12.3% increase), though single still boosted 7.4%, compared control treatment.
