Abstract

The present investigation entitled “Impact of metabolite elicitors on growth and yield characteristics in turmeric (Curcuma longa L.) at high altitude zone of Andhra Pradesh” is carried out at HRS, Chintapalli, Dr. Y.S.R. Horticultural University, during Kharif 2017 and 2018. The metabolite elicitors chitosan and salicylic acid were administered to two varieties, Mydukur and Roma, in the form of seed treatment and foliar spray. At 180 days after transplanting (DAT), growth characteristics were noted. At harvest, yield was noted at 250 DAT for the variety Roma and 270 DAT for the variety Mydukur. Pooled data over two years (2017-18 & 2018-19) on growth parameters and yield revealed significant effect on plant height (103.21 cm), number of leaves plant-1 (11.49), leaf length (44.48 cm), leaf width (11.56 cm), number of tillers plant-1 (1.68), fresh weight plant-1 (439.52 g) and yield plot-1 (8.38 kg) were recorded in the variety Roma. Significantly superior plant height (96.32 cm), number of leaves plant-1 (12.15), leaf length (44.97 cm), leaf width (12.09 cm), number of tillers plant-1 (1.75), fresh weight plant-1 (419.98 g) and yield plot-1 (7.67 kg) were recorded in the foliar application of chitosan @ 100 ppm as the effect of metabolite elicitors through foliar application is observed superior to seed treatment. The combinations of variety Roma + chitosan @ 100 ppm (S), Roma + chitosan @ 100 ppm (F) and chitosan @ 100 ppm (S) + chitosan @ 100 ppm (F) recorded significantly highest growth and yield characteristics. The three-way interaction Roma + chitosan @ 100 ppm (S) + chitosan @ 100 ppm (F)recorded superior plant height (113.80 cm), number of leaves plant-1 (13.74), leaf length (50.76 cm), leaf width (13.34 cm), number of tillers plant-1 (2.24), fresh weight plant-1 (527.74 g) and yield plot-1 (10.87 kg) and lowest was recorded with Mydukur + no seed treatment + water spray.

Conclusion

The response of Roma to metabolite elicitors was proved to be high when compared to Mydukur at high-altitude zones of Andhra Pradesh. This study highlights the significance of chitosan in exhibiting its role on growth and yield characteristics in turmeric at high-altitude zone of Andhra Pradesh. Salicylic acid followed chitosan in registering relatively more growth and yield. Foliar application of elicitors has more impact on the crop grown than seed treatment.
