Abstract/ Executive Summary:

Extension of tea planting was started in 2002 at Panchagarh, the Northern area of Bangladesh to meet up our increasing demand. The climatic condition and soil environment of Panchagarh soil is different from that of greater Sylhet and Chittagong. On the basis of production a fertilizer recommendation has been introduced in these areas. As the climatic condition and soil environment is different from that of Sylhet and Chittagong and experiment has been initiated in Karatoa tea estate. In the year 2008 to find out the fertilizer recommendation on the basis of production. The plucking data recorded at weekly interval along with other cultural practices.The trend of result shows that, yield increase with the increase of fertilizer dose. Highest yield was recorded in the treatment T7 where N120, P60 and K100 were applied followed by treatment T6. The experiment is Statistically Significant.
