The country had harvested 3.18 lakh tonnes of coffee in the 2012-13 marketing year (October-September).
Releasing the revised estimates, the Coffee Board said that total coffee production is expected to be 3.11 lakh tonne in 2013-14, down by 10.23% from the earlier estimate of 3.47 lakh tonnes for the same period.
Production of Arabica has declined by 8% to 1.02 lakh tonnes, while that of Robusta has declined by over 11% to 2.09 lakh tonne, from over the earlier estimate. Maximum drop in production was seen in Karnataka and Kerala.
Citing reasons for lowering production estimates, the board said, During the current season, coffee areas have witnessed a long period of drought after receiving blossom showers, followed by an extremely harsh monsoon.
Due to a long period of drought in April-May, there was heavy proliferation of White Stem Borer disease but subsequent monsoon rains helped in preventing further spread of this pest.
Later, extended rains led to soil saturation and wet feet conditions resulting in defoliation, berry drop and incidences of stalk rot and black rot, it added.
As per revised estimates, coffee output in Karnataka is pegged at 2.17 lakh tonne, Kerala at 67,275 tonne, Tamil Nadu at 18,875 tonne, Andhra Pradesh at 7,010 tonne, Orissa at 440 tonne and north east region at 200 tonne this year.
Currently, harvesting of Arabica is almost complete, while that of robusta will continue till March.
