Abstract:
India is called the "Botanical Garden of the World" as it contains several medicinal plants and herbs that are traditionally used to cure ailments. Curry leaf is one such plant with a wide range of medicinal properties. Twenty genotypes of curry leaves were analysed to optimise the correct harvesting maturity with respect to yield, essential oil, oleoresin and beta-carotene. A field experiment on Optimization of harvesting interval in curry leaf was conducted at Spices research field, Department of spices and Plantation Crops, HC&RI, TNAU, Coimbatore during the year 2021-2022.The experiment was laid out in FRBD with three replication and three treatments. The experimental result revealed that G10 recorded maximum yield (0.53 kg/plant), essential oil (0.25%), oleoresin (12.51%) and beta-carotene (7.81 mg/100g) content and G1 was the lowest essential oil (0.01%) yielding genotype followed by G19 with respect to oleoresin (9.91%) content. There is a significant change in the quality and yield of curry leaf with respect to harvesting interval. Among the three different harvesting intervals (H1- 2 months after pruning, H2- 3 months after pruning, H3- 4 months after pruning) H2 was the best harvesting interval to get higher yield and quality of curry leaf for all genotypes.
