| dc.description.abstract | The present experiment entitled “Influence of pre and post-harvest treatments on growth, yield and storability of tomato (Solanum lycopersicon L.) was carried out in Polyhouse, Laboratory of the Department of Vegetable Science, Post-harvest laboratory of Horticulture Science, Centre of Food Science and Technology, CCS Haryana Agricultural University, Hisar during Rabi season of 2022-23. The whole study was divided into two experiments. In the first experiment, there was evaluation of various pre-harvest treatments on growth, yield and storage behavior of tomato cv. Punjab Sartaj grown under polyhouse. In the second experiment, there was evaluation of various post-harvest treatments on quality and shelf life of tomato fruits cv. Punjab Sartaj harvested from the first experiment at turning stage. In experiment-1, the application of pre-harvest treatment T4: RDF + SWE (5ml/L) and PUT (0.1g/L) recorded minimum days to 50% flowering (39.33), maximum no. of fruits/cluster (6.37), maximum no. of fruit clusters/plant (15.11), maximum no. of fruits per plant (96.26), maximum average fruit weight in (84.93 g), maximum fruit diameter (5.38 cm) and maximum total yield (1,91,642.6 kg/ha) or (191.64 q/ha), whereas, treatment T10: CaCl2 (200 mg/l) + EBM (2 kg) recorded maximum plant height at 45, 90 and at final harvest (98.03 cm, 192.73 cm, 323.93 cm) respectively. Among the various pre-harvest treatments, treatment T4: RDF + SWE (5ml/L) and PUT (0.1g/L) recorded minimum physiological loss in weight (4.72%), maximum fruit firmness (11.77 kgf), minimum decay loss (9.14%), maximum shelf life (15 days), maintain maximum general appearance (4.50), maximum ascorbic acid (25.24 mg/100 g), maximum TSS (4.95°Brix), maximum total sugars (8.77%), maximum juice content (56.82%), minimum lycopene (3.52 mg/100 g), maximum total phenolic content (34.42 mg/100 g) and maximum titratable acidity (0.46%). The economics of various treatments with benefit to cost ratio and net return was also calculated and the maximum benefit cost ratio (2.93:1) was obtained from treatment T2: RDF + SWE (5ml/L). So, the application of seaweed extract and putrescine helps in increasing overall growth parameters and maintains physio-biochemical quality. In experiment-2, the post-harvest treatments, T4: chitosan (0.5 g/100 ml of water) + seaweed extract (0.5 g/100 ml of water) recorded minimum physiological loss in weight (7.41%), maximum fruit firmness (12.70 kgf), minimum decay loss (7.35%), maximum shelf life (38 days), maintain maximum general appearance (4.72), maximum ascorbic acid (24.45), maximum TSS (5.25°Brix), maximum total sugars (9.11%), maximum juice content (47.52%), minimum lycopene (3.53 mg/100 g), maximum total phenolic content (51.14 mg/100 g) and maximum titratable acidity (0.44%). So, the application of chitosan and seaweed extract maintains the post-harvest quality of tomatoes stored under ambient conditions. | |
