Abstract

The turmeric crop is affected by three major fungal diseases and the yield of rhizome varied due to the incidences of disease and variety performance. A study was conducted to assess the suitability of varieties against fungal diseases in Cuddalore district of Tamil Nadu. Three varieties viz., CO2, IISR pragathi and Attur ruling variety were used to assess the performance against the fungal diseases under field condition. The growth parameters and incidence of rhizome rot in turmeric was recorded from the on farm trial and the results indicated that rhizome rot incidence was low in CO2 variety (2.12 %) and which was followed by IISR pragati (4.51%). The highest yield of rhizome was recorded by CO2 variety and which was followed by attur local variety. In the experiments, IISR pragati matured very earlier than other variety used in the study.  The CO2 variety given higher net profit and B: C ratio in the study. The disease incidence viz., rhizome rot, leaf blotch and leaf spot were noticed in all the three varieties; however, rhizome rot incidence was very low in CO2 variety and followed by IISR pragati. The incidence of leaf blotch and leaf spot were comparatively less in IISR pragati when compared to CO2 variety.
