Abstract:
Spices constitute an important group of agricultural commodities, which is considered as low volume and high-value crops. Turmeric (Curcuma longa L.) belongs to the family: Zingiberaceae is one of the most important spices of the world, which is commercially cultivated for rhizome, called as “hidden Lilly” or “turmeric of commerce” and “golden spice of life”. Maximum temperature and minimum temperature showed (r= -0.793, r= -0.886) significant negative correlation with the leaf spot of turmeric. This indicates that the disease incidence increased with lowering down of maximum temperature. Rainfall (r= -0.389) reveals that disease severity is negative correlated but not significant. Relative humidity (r= 0.191) showed positive correlation with the disease severity which clearly indicates that the disease increased.
