Abstract

The experiment was conducted at Horticultural Research Station, Mondouri, BCKV, West Bengal, during 2019-2020 and 2020-2021. According to recent research, the application of metabolic elicitors had a major impact on yield and quality. Elicitors like chitosan, salicylic acid and methyl jasmonate, were found to show positive effect on growth, yield and quality in various crops. The ultimate objective of this study is to identify the best elicitor and its concentration for enhancing the production of turmeric. The plants were foliar sprayed with different metabolite elicitors viz., chitosan (250, 500 and 750 ppm), salicylic acid (100, 200 and 300 ppm), proline (50, 100 and 200 ppm) and methyl jasmonate (50, 100 and 200 ppm) at 60, 90, 120 and 150 days after planting (DAP). The plants under control plots were sprayed with distilled water as per the schedule. Significant variations in most of the parameters were observed among different treatments during both the years and in pooled analysis. The plants sprayed with salicylic acid-200 ppm recorded maximum number of tillers (3.47), clump weight (348.81 g), length of primary finger (9.64 cm), breadth of primary finger (2.36 cm), number of secondary fingers (15.35), yield plot-1 (13.26 kg 3m-2), projected yield (33.14 t ha-1), The maximum number of primary fingers (11.57), weight of primary finger (161.45 g) and breadth of secondary finger (1.90 cm) were observed in salicylic acid-100 ppm. The maximum plant height (184.72 cm), number of leaves (20.90) and tiller (3.47) were recorded in salicylic acid-300 ppm. The maximum length of clump (18.88 cm), breadth of clump (16.45 cm), length of secondary finger (4.69 cm), the maximum weight of primary finger (183.90 g) was recorded in methyl jasmonate -100 ppm.

Conclusion

Considering the yield per plot and projected yield per ha the most effective treatment among different elicitors was salicylic acid 200 ppm followed by salicylic acid 300 ppm and chitosan 750 ppm towards improving the production of turmeric. These two elicitors are proved to be the best when compared to other elicitors on turmeric. at Horticultural Research Station, Mondouri, BCKV, West Bengal. Salicylic acid followed chitosan are affecting more impact on growth and yield parameters. These two elicitors can be suggested to the farmers for higher yields and increasing farmer’s income.
