Different climatic data observation and its effect on tea crop

Rainfall particularly, is an agro-met factor that generally playing a significant role on all agric crops including tea. There is considerable spatial and temporal variability in rainfall others data characteristic, which affect tea crop production and soil erosion problem. For the adoption of soil water conservation technique, the information of rain fall with the other agro-met factors in general is very important. This paper describes all the agro-met characteristic in relation with the tea crop production nearby suburb of National Tea Research Institute Shinkiari, located at 25km north of Mansehra city on the Karakoram Highway way to China silk route , it is located at 34°28 0N, 73°16 60E at an altitude of 1019 meters (3346 feet). A detail production of tea crop during all the eleven years were also discussed for the efficient utilization of available water for the sustained productivity. It was observed that winter season comprising on 7 month while summer period shorten on 5 months only. However days length and time was countable. In all the 11 years average maximum rain fall was received 209 mm during summer (July) followed by 108mm during February in winter seasons. Minimum average rainfall of 30 31 mm was received in Oct Nov respectively. Maximum average rain fall events (139 mm) were recorded during 2010 followed by 125 mm in 2005. Maximum temperature 370C shoot up in June 2003, while minimum-1 observed in January 2011. Evapotranspiration of 0.96 mm at minimum level during December 2008 and 0.670 mm in July 2004 was recorded. 3.327 mm evapotranspiration was observed during all the eleven years of study it includes 4 years of wettest 2001 without any data. Humidity difference during all 11 years was in minimum and maximum range of 43 – 78 % respectively. This attributes shows the climatic effect on tea crop during fermentation of black and deoxidizing of green tea. Maximum made tea in total was 12221 kg/annum during 2008 with rainfall 1092 mm, although it was less as compare to 2010, 2007, 2005, 2002 and 2001 respectively while other climatic factors were also responsible for the maximum production
