Foliar Urea with N-(n-butyl) Thiophosphoric Triamide for Sustainable Yield and Quality of Pineapple in a Controlled Environment

In agricultural production, nitrogen loss leads to economic and is a high environmental risk affecting plant growth, yield, quality. Use of the N fertilizer with urease inhibitor thus necessary minimize losses increase efficiency N. This study aimed evaluate effects N-(n-butyl) Thiophosphoric Triamide (NBPT) on quality pineapple. The experiment involved two foliar treatments: 1% (w/v) urea solution NBPT (2.25 mL kg−1 urea) was treated as NLU (NBPT Liquid Urea), same concentration without served control. Both were applied 12 times, starting 1 month after planting (MAP) continuing once for months. application notably increased above-ground dry biomass per (20% 10% at 8 MAP, respectively), leaf area (23% 15% accumulation (10%), PFPN (Partial Factor Productivity) (13%), average fruit weight (15%) compared treatment alone (control). analysis parameters indicated that improves TSS (Total Soluble Solids) (19%), ascorbic acid sucrose (14%) but reduces total organic content (21%) in When using (NBPT), there significant improvement quality, use efficiency, additional benefit reduced losses, combination easy handling. Hence, can be used viable alternative increasing pineapple yield by boosting growth better
