Excess rainfall hits tea
Guwahati, Assam, May, 2016
Although rainfall and other parameters of favourable weather conditions
helped the State tea industry break past records in the area of production
in March this year, during the subsequent pre-monsoon period, the
same pace of growth slowed down considerably due to the excess downpour,
hailstorms and cyclones in the specified tea gardens of Jorhat, Dibrugarh,
Golghat, Barak Valley and the North Bank of the Brahmaputra.
Research-based data collected by the Tea Research Association (TRA) from the tea gardens of the specified sub-areas like Dibrugarh, Panitola, Tingrai, Margherita, Naharkatiya and Moran revealed that the excess rainfall received during the month of April did not help much in crop growth.
In March, the gardens of those sub-areas produced a total of 52,81,524 kg of green leaves. But in April, the total production decreased to 49,42,740 kg. During the corresponding month of last year, those gardens showed higher production with 59,09,500 kg of tea leaves, the TRA findings stated.
With the exception of Tingrai and Moran sub-districts, all others harvested crop lesser than that was harvested in April last year, the findings revealed.
The specified tea gardens of the sub-areas received excess rainfall amounting to 3,645 mm during the month of April. The amount of rainfall was 1,895 mm in the corresponding period last year in all those tea gardens.
However, referring to these tea gardens, experts of the TRA remarked that the crop prospects for the month of May appeared good subject to improvement of weather conditions, which will help in completing ground manuring soon as well as controlling pest population.
The TRA findings in the specified gardens of the sub-areas like Nagaon, Tezpur, Biswanath, Mangaldai, Borsola and North Lakhimpur on the North Bank of the Brahmaputra stated that crop production remained ahead by 5.05 per cent in April against the corresponding month of last year.
In the North Bank, the gardens of the Mangaldai sub-area received the highest amount of rainfall of 295.16 mm in April this year.
Scientific data received from specified gardens of Jorhat, Golaghat, Sonari-Nazira sub-areas of the South Bank region stated that the tea crop harvested last month was rather low. The specified gardens produced 12,47,178 kg of green leaf in the month of April this year, against the 13,15,485 kg produced in the corresponding month last year.
"In all the three sub-areas of the South Bank and they produced lesser quantity of tea compared to last year, viz. Sonari Nazira (-31.02 per cent), Jorhat (-8.28 per cent) and Golaghat (-23.78 per cent). The average total production in the South Bank for the month of April was lower by 25.80 per cent compared to last year," the TRA data stated.
The weather data of the garden areas stated that the amount of rainfall was higher compared to the rainfall of April last year.
"The average maximum temperature recorded in the South Bank was lower than last year, while the average minimum temperature was higher in all the sub-areas of the South Bank," the findings revealed.
The gardens of Happy Valley, Chutlabheel, North Cachar, Hailakandi, Longai and Karimganj also witnessed hailstorms, cyclones and heavy rainfall quite frequently in April this year, which had a negative impact on production of green leaf. Workers could not carry out their routine works in the adverse weather conditions. However, the absence of drought rejuvenated the gardens of the sub-areas of the Barak Valley during the month of April this year and the gardens were ahead in production by 19.20 per cent compared to the production of April last year.
These gardens had suffered severely from drought last year.
