ABSTRACT
Turmeric (Curcuma longa L.) is a golden spice belongs to the family zingiberaceae. It is the national spice of India. Turmeric inhibits the development of cataracts, breast cancer, colon cancer and lymphoma. However, except from its medicinal use, its fresh juice the aqueous extracts and the essential oil of the plant are credited with pesticidal properties against mosquito. An experiment was conducted in a farmer’s field at Bharathipuram village, Pennagaram Taluk, Dharmapuri District, Tamil Nadu during May to January 2021 to study the response of different micro nutrients on yield parameters of turmeric. Turmeric cv. BSR2 was used for the experiment. The experiment was laid out in Randomized Block Design with nine treatments and three replications. The treatments comprised of soil application of boron (Borax), Manganese (MnSO4), Iron (FeSO4) and Zinc (ZnSO4) each @ 25 kg ha-1, foliar application of boron (Borax), Manganese (MnSO4), Iron (FeSO4) and Zinc (ZnSO4) each @ 0.5% after 60 and 90 days after planting. In control no micro nutrients were applied. Inorganic fertilizers were applied at the rate of 80:80:120 kg ha-1 of N: P2O5: K2O to all the treatments. Observations on yield parameters like number of mother rhizomes per plant, number of primary fingers per plant, number of secondary fingers per plant, yield per plant and yield per hectare were recorded. The results revealed that soil application of boron as borax @ 25 kg ha-1 recorded the highest yield parameters of turmeric cv BSR2.
