Training and Pruning in Coffee Gardens
The plant is trained either on single stem or multiple stem system. Usually coffee, both arabica and robusta, is trained on single stem. When the plants reach a desired height of 75 cm for arabica and 105-120 cm for robusta, they are topped i.e., growing apex of the stem is severed. Low topping (60-70 cm) is advocated in areas of severe wind and exposure. Under certain circumstances, multiple stem system is also adopted as in the case of replanted fields or when under-planting is taken up keeping the old plants under multiple stem system.
Pruning in coffee is done immediately after
harvest and till the onset of monsoon. Pruning involves: -
The type and frequency of pruning have to be decided based on a number of factors like the type of vegetative growth, incidence of pests / diseases, pattern of blossom showers etc. Centering and desuckering are to be carried out for about 5 or 6 years after planting. Removal of the dead and whippy wood is essential during the early years. Mature plants may require medium to severe pruning once in four years.
