Interaction of the Coupled Effects of Irrigation Mode and Nitrogen Fertilizer Format on Tomato Production

The production efficiency and quality of tomatoes is affected by the mode irrigation nitrogen forms. This study explored impacts different regimes, forms, their coupled effects on tomato production. various regimes were set at 50%FC~90%FC (W1), 60%FC~90%FC (W2), 70%FC~90%FC (W3), 80%FC~90%FC (W4) Furthermore, control (CK) group followed a conventional drip regime in local area. Nitrogen forms this comprised urea-based fertilizer (urea N 32%, F1), nitrate-based (calcium ammonium nitrate 15%, F2), ammonium-based (ammonium sulfate 21%, F3). Combining these two factors yielded 15 treatment groups. experiment was conducted solar greenhouse, soil type sandy loam soil. research focused observing yield, quality, water–fertilizer use under results demonstrate that had more significant impact yield nutrient accumulation rate compared to To comprehensively evaluate tomatoes, combination evaluation method employed. W3F2 produced highest CKF2 achieved comprehensive score, W2F2 water score. Using fuzzy Borda model, information three dimensions combined. ranked first, suggesting adoption an 70%FC 90%FC, along with application during fruit harvest stage. It presented best performance across multiple dimensions.
