Abstract
This investigation evaluated the impact of preharvest nano calcium (nano Ca) sprays on tomato yield, physicochemical attributes and shelf-life performance under field conditions at the College of Horticulture, Anantharajupeta, Annamaya district. A total of twelve treatments comprising nano Ca, including varying concentrations ranging from nano Ca 50 to 500 ppm, were sprayed at 30 and 45 days after transplanting. The application of results indicated that nano Ca at 350 ppm significantly increased the total number of fruits (45.90) and yield (1.83 kg) per plant, while 500 ppm notably improved fruit firmness (4.28 kg cm⁻²) and extended shelf life (14.33 days). Nano Ca treatments also modulated biochemical parameters, with higher concentrations resulting in elevated titratable acidity and diminished lycopene content, attributed to reduced activity at higher concentrations due to suppressed ethylene biosynthesis and enzymatic activity. In conclusion, optimized nano-calcium application significantly enhanced yield and postharvest quality, offering a promising strategy to reduce spoilage and enhance the shelf life of tomato.
