Clonal propagation of tea

Tea plant can be grown using both seeds and cuttings, it is called vegetative propagation. Plants raised from cuttings are called clonal seedlings. They are true to type and contain same qualities as that of their mother plants. Clones are preferred because of low tree mortality, less maintenance and better growth rate. They can be directly raised in poly sleeves or transplanted from nursery bed after callous formation to poly sleeves.Tocklai experimental station released clones for the first time in 1949 by adapting clonal selection procedure. 


Clonal seedlings propagation is carried out by using single leaf internodes cuttings. These cuttings are prepared from the flexible middle portion of pruned shoots taken from selected mother bush. Propagation is mostly carried out in spring (mid April to early June)and Autumn (mid Spt to mid Oct).The number of healthy cuttings obtained from one mother bush may vary from 50 to 300 per annum. 

Categories of clones:

Clones are categorized as:

a.Standard clones: Above average yield and quality with yield potential of 3000 to 3500Kgs made tea/ha. The important suitable varieties in our state are; TV 1,TV 10,TV 11,TV 14,TV 16,TV 17,TV 20,TV 24,TV 27,TV 28.

b.Yield clones:      Average quality but high yield with yield potential of 4000Kg made tea/ha. The varieties are TV 9,TV 18,TV 19, TV 22,TV 23,TV 25,TV 26,TV 29,TV 30.

c.Quality clones: High quality but average yield with yield potential of 2500 to 2800Kgs made tea/ha. The variety TV 21 is the recommended one.

Preparation of rooting bed:

         For spring season propagation nursery bed preparation should be completed by December and for Autumn season it should be completed by April. The bed should be raised and drainage system should be provided between the beds at 50-60cm deep for quick run-off 0f surface water. Beds should be provided shade or it should be covered with leaf mulch to protect from direct sunlight. It takes 5-6 weeks for the soil to attain the desired compactness. Adequate time should be kept between nursery bed preparation, filling of poly sleeves and planting of cuttings to avoid failure of the nursery.

Character of a good shoot:

The shoot to be collected for leaf cutting should have

a.True to type

b.Free of disease and insect pests

c.In proper physiological state so that the cuttings taken from them are likely to root.

Taking of shoots from mother bush.

a.Shoots should be taken both in morning or evening and not in hot sun.

b.Cut the shoot 2-3 cm above last prune mark during Autumn and 8-10 cm above during spring.

c.Immediately after cutting, the shoots may be put in a bucket of water shoots or wrapped in wet hessian cloth.

d.Carry the  shoots to  nursery site quickly

e.Do not expose the cut shoots to the sun.

Preparation of leaf cuttings:

a.Discard top succulent and hard basal woody portion of the shoots

b.Select only the middle flexible part of the shoot to make cuttings.

c.Discard any unhealthy leaf or leaf with growing auxiliary buds

d.Make 3cm long single leaf cuttings

e.Make sharp slanting cuts parallel to the leaf axis

f.Avoid injury to the mother leaf and auxiliary bud and park of the cuttings

g.Cuttings with more than 80cm leaf area be cut into half to get better rooting

h.Keep cuttings covered with moist hessian cloth and do not expose to sun

Setting the cuttings in rooting beds:

a.Irrigate the beds lightly with water cane before planting

b.Adapt a spacing of 5cmx 8cm for small leaf and 8cmx 10cm for large leaf in triangular design

c.Use dibber of accurate length with slightly smaller than stem of the cutting for making holes in bed

d.Make holes at every notch in vertical or inclined manner

e.Hold the cutting in between the thumb and the first finger with the leaf pointing away

f.Plant the cutting in the hole in inclined manner so that the leaf remains pointing upwards

g.Fix the cutting firmly by pressing the soil around the stem so that no air pocket remains below

h.All cuttings should face same direction preferably west or north 

After care:

a.Irrigate the cuttings slightly after planting

b.Cover the beds with lath frames or provide shades

c.Observe the bed regularly and irrigate whenever required 

Weed management:

            Weed growth is more intense during the early stages of tea plants hence regular weeding should be done to check the weed growth . Chemical weedicides like Glycel, Simazine, Paraquate and 2,4-D(Fernoxone) are effective in controlling weeds.

Success Stories

Cultivation of off season cucumber

Cultivation of off season cucumberCucumber has been traditionally cultivated by Naga farmers in their jhum fields as a mixed crop during the Kharif season (April to August). It is one of the important component crops in the Jhum field and the harvest is used, mostly for household consumption and sometimes sold at the local market. Kharif crops of cucumber are harvested during...
