Plucking in Tea

 Plucking 

The tender apical portion of shoots consisting of two to three leaves and the terminal buds are nipped of in Plucking. 


  • Plucking System - Shoots may be plucked above

  1. Basal Janams
  2. Janams & Fish Leaves
  3. Janams, Fish Leaves & Single foliage leaf.


  • Average Pluckers/ ha. - 10


  • Average Plucked leaves/Pluckers - 24 kgs


  • Plucking Rounds - Completion of Plucking is called Plucking round. 

  1. Although 7 days round is most common.
  2. In year 30 - 32 rounds leaf plucked in a section or Tea Estate.


  • Laterals - The branches of the primaries(growing shoots) are the laterals of the first order.

  1. 10 orders of laterals can be produced in a year.


  • Plucking Standard - A bud & two leaves to be plucked. 


  • Type of Plucking...

  1. Fine/Black Plucking - All 1 + Bud, All 2+ bud(Terminal bud & small 2 leaves & soft single Banjhies).
  2. Standard/Normal Plucking - Bud with small 2-3 leaves & soft single Banjhies.
  3. Medium Plucking - Bud with all 2-3 leaves & soft double Banjhies.
  4. Coarse Plucking - Bud with all 3-4 leaves & double Banjhies. (Generally Hard,black, coarse & big leaf is not allowed in quality tea manufacturing)


  • Step Up in Plucking - Raising by a leaf is called Step Up, it is advantageous in late October if the tea is to be kept Unprune in the following year.


  • Breaking Back - In this process remove (slightly skiff) the leaves & stems (which are not considered suitable for manufacturing) above the Plucking surface in order to maintain a flat surface.


  • Reason for Growth - With the process of Photosynthesis plants grow..
  • Photosynthesis - In the presence of light (673 kilocalorie) & Chlorophyll plants make their food (Carbohydrates/Glucose)  & Oxygen with the help of carbon dioxide & water.

  1. 6Co2+ 12H2O → C6H12O6+ 6H2O+6O2
  2. The Photosynthesis efficiency of a mature leaf gradually declines after 6 months.


  • Leaf drop - In tea after about 18 months plants drop his old leaves.

 

  • Dormancy in Tea -
  • The winter dormancy is in N.E. area because day length is low of 11 hour 15 minutes and also no photosynthesis in lower than 12°C & higher than 40°C of leaf temprature.


  • Estimated percentage Crop of Month & Pruning wise :-

Doses  - 250 - 500 gram/Bush Species of Earthworm -            Species      - P roduce   "N"    - V.Compost Eudrilus eugeniae     -1.58% - 59 kgs/cycle Amynthas diffringes -1.42% - 52  kgs/cycle Eisenia Foetida          - 1.41% - 46  kgs/cycle Perionyx excavates   -1.36% - 43  kgs/cycle Lampito mauritti      - 1.30% - 39 kgs/cycle Process to Preparation of Vermicompost - 1.Construct a concrete tank 3 foot up from ground level in size of 10' X 4' X 1.5'(length X Breadth X Depth) with thatch roof. 2. Use bio-waste chopped and heaped under sun for 5-7 days.   3. Feed 150 kgs cowdung + 250 litres water (ratio 3:5) and mixed well to make slurry. 4. Add 350 kgs bio-waste & kept it 24
