Vegetative propagation is carried out for clonal multiplication while biclonal seed stocks are propagated through seeds. The Tea nursery should be located near a perennial water source.. An over head 'pandal' is raised on which a coir mat with 6 mm2 mesh is spread so as to allow about 33 percent sunlight at midday into the nursery. Polythene sleeves with a dimension of 30x10 cm are used for filling up the sandy loam/clayey loam soils. One leaf and an internodal cutting with an axillary bud prepared from the ‘aperiodic shoots’ arising from pruned tea bush is planted in the nursery sleeve and covered with a polythene sheet of 400 guage. April / May and August / September are the most suitable months for planting in nursery. The plants are allowed to grow for 10-12 months in the nursery, after which they are transplanted in the field.


Three to four months after planting, apical dominance is arrested by cutting off the leader stem. This operation, called centering (or decentring), promotes the growth of axillary bud's and lateral branches are formed. For further lateral branch formation, good spread and establishment of plucking surface the growing branches are trained by two stage tipping. First tipping is carried out at 35 cm followed by second tipping at 50 cm.


Formative pruning (branch formation pruning) is carried out at the end of five years after planting. The recommended pruning height for formative pruning is around 45 cm. At the time of formative pruning branches which are less than pencil size thick are removed.


Young tea fields and the fields immediately after pruning are to be hand plucked. Fields that have crossed more than 15 months from pruning can be harvested with the help of hand held shears. Shear harvesting increases the productivity of the workers. Hand helded motorised harvesters have been evaluated and found useful to achieve high labour productivity. Both the one man and two men operated Kawasaki and Ochiai motorized harvesters are useful in tea fields planted on moderate and gentle slopes. The battery operated harvesters are also useful to increase the productivity of the women pluckers. Pneumatic harvesters had also been field tested.


Grevillea robusta commonly called as Silver Oak is the recommended shade tree for tea in south India. The finely dissected leaves facilitate filtering of light and the deep root system does not compete with tea for nutrients. The tree is also suitable for pollarding and periodical lopping to regulate shade. Grevillea trees can also support the growth of pepper which is intercropped with tea.



The most common grass weeds in south Indian tea fields are, Axonopus compressus (Sw.) P.Beauv (Carpet grass), Digitaria adscendens [HBK] Henr. (Crab grass), D.longiflora Pers (Finger grass), Panicum repens L.(Couch grass/Ginger grass), Paspalum conjugatum Berg(Buffalo grass). The common dicot weeds are, Ageratum conyzoides L. (Goat weed), Bidens biternata (Lour) Merr. & Shreff. (Spanish needle), Crassocephalum crepidioides (Benth) Moore. (Pile wort), Conyza ambigua DC, Mitracarpus verticillatus (Schum. & Thonn.)Vatke.

Backpack sprayers fitted with WFN 0.024, 0.040 and VLV-50 nozzles are used for spraying the recommended herbicides. Both the pre and post emergence herbicides are useful to control the weeds in tea fields. Pre emergence herbicides such as diuron and oxyfluorfen can be applied in young tea fields and in the pruned tea fields. The contact post emergence herbicide like paraquat is useful to control the weeds during the monsoon seasons. The translocated type of herbicides such as glyphosate and 2, 4-D can be sprayed during the pre and post monsoon seasons.
