Sources from the Kannan Devan Hills Plantations (KDHP) Limited, one of the major tea plantations in Munnar, said that the low rainfall will affect tea production. “The two major tea cropping seasons are from second week of April to May and from second week of September to October. Normally, ground fertilizers are applied in the second week of August, and it would reflect the production in September’s second week,” said the source.
“Due to the absence of rainfall, the ground fertilizers have not yet been applied in the plantations. Continuing the same situation will negatively affect the tea production,” said the source.
Climatologist Gopakumar Cholayil said, “Rain and chilly weather are the major attractions of Munnar hill station during monsoon season. Due to shortage of rain, the heat index will increase, which will affect the arrival of tourists in Munnar in October and November,” he said.
“The absence of rain would affect both plantation and tourism sector in Munnar, including hill stations,” he said.
According to India Meteorological Department (IMD) data, while Idukki district receives 2,122.8 mm of rainfall till August 26 during a normal monsoon year, the district recorded only 785.4 mm of rainfall this year.
