Subject: What are the important factors for establishing a Coffee Plantation?
Message: Dear Planter, In order to establish a healthy and vigorous plantation, following factors must be considered;while choosing the site for planting, one should look for the altitude, rainfall, the wind flow over the terrain, round the year source of water and presence of good tree shade cover. After preparing the land for coffee planting, pits for planting should be made during March-April, after a few summer showers and exposer to sun light atleast for 2-3 weeks in ororder to kill soil borne pests and roots of trees and old plants. This principle should be adopted in areas identified for replanting also. The pits should be filled with top soil mixed with 1 to 2 kg of farm yard manure and 50g of Rock Phosphate. Only vigorous growing, disease free seedlings should be planted in the field. Dadap and saplings of desirable shade trees should be planted without fail. ; Maize-toria-wheat; Maize-wheat-mung bean or urd bean; Maize-potato-maize; Maize-wheat-cotton-berseem; Maize-oat-napier grass; Maize-senji-sugarcane-cotton; Maize-wheat-sorghum-sugarcane and Maize-wheat-sugarcane.

Subject:What are the recent trends in Pruning Methods?
Message: Dear Planter, In recent years skilled manpower is not available for carrying out pruning operation which is important for obtaining regular, consistent yields. Hence, it is necessary to adopt new pruning methods like Rock-n-Roll pruning and cyclic pruning which does not require skill. To implement these new methods of pruning, it is necessary to plant the coffee in hedge row method and train them on multiple stem system. After the initial establishment of plants in hedge row method, the plants should be topped at 2 feet height to form a lower supporting canopy. When the main stem is adequately thick, allow 2-3 suckers on each plant in a given row at the interval of 4 rows. That means suckers are allowed on all plants in 1st row, 5th row, 9th row and so on during the first year and on 2nd row, 6th row, 10th row and so on during second year. This is followed till the suckers are established on all rows in a 4 year period. During the 5th year, the suckers present on 1st row, 5th row, 9th row are cut back after harvesting and a fresh set of suckers are allowed for form a second round of cropping cycle. This method is called as Rock-n-Roll method. In cyclic pruning, after establishing the lower supporting canopy, suckers are allowed on all plants within a plot in the same year and after each harvest one sucker per plant are cut back and a new sucker is allowed to replace the old sucker.

Subject: How does white stem borer damage the coffee plant?
Message: Dear Planter The larvae of stem borer tunnel extensively into the main stem cutting off water and nutrient supply to branches and leaves leading to wilting of plants. In young plants tunneling is mainly seen at the lower part of the stem sometimes extending to the root region leading to early death. Older plants may withstand the attack for a few seasons. The affected plants yield less fruits with high percentage of floats resulting in low out-turn. All Arabica selections are susceptible to borer attack. An infestation level of 10 plants per acre is considered to be low, between 10 to 25 plants to be medium and above 25 plants as high incidence.

Subject:What are the ways to reduce the borer incidence?
Message: Dear Planter The stem borer can be effectively controlled by an integrated approach comprising of maintenance of good shade cover; tracing and destruction of infested plants once during March and September every year; removal of loose scaly bark on main stem and thick primaries of remaining healthy plants with coir gloves and swabbing / spraying the main stem and thick primaries with 10% lime solution. Wrapping the main stem and thick primaries with woven polythene strips is also recommended as an alternative to scrubbing and lime coating. Installation of pheromone traps during flight period (April-May and October-December) at the rate of 25 traps per hectare will also help in trapping the adult beetles. In areas prone to severe attacks, spraying the main stem and thick primaries with Chlorpyrifos 20EC @ 600 ml in 200 litres of water along with 200 ml of wetting agent is recommended once during first fortnight of April and again in first fortnight of October.

Subject: Is it advisable to inter-plant Arabica in Robusta?
Message: Dear Planter Yes, interlining of arabica in young robusta blocks is advisable. The idea is to exploit the available space between the plants during the initial years so that some additional income can be obtained from Arabica. However, if arabica is planted in robusta blocks, the requirements of both these plants should not be compromised. Proper care has to be taken for arabica especially with respect to nutrition management, rust control measures and white stem borer management practices. Once, the robusta plants are covered, the arabica plants have to be uprooted irrespective of the plant condition so that the growth of robusta plants is not affected.

Subject: How to raise Robusta clones?
Message:Dear Planter Clonal propagation of robusta is easy in which orthotropic shoots or suckers are used for raising clones. Before taking up clonal propagation, a large number of elite mother plants have to be identified. After summer showers, allow the growth of suckers on the identified plants. After the onset of monsoon, collect suckers of pencil thickness, approximately 3 to 6 months old and prepare single node cuttings of 10 cm length with a pair of trimmed leaves making a basal slant using secateur without damaging the tissue. Immerse the single node cuttings in Bavistin solution of 4 gm/litre of water strength for a while to prevent fungal contamination. Dip the cuttings in 5000ppm IBA solution for 5 seconds and plant in the polybags arranged in rooting trenches of 1 meter width, 0.5 meter depth and 2 to 6 meters length, under overhead shade. After planting, trenches have to be covered with 500 gauge polythene sheet supported by either bamboo or iron frame and provide regular watering. Cuttings planted in trenches root in about 2 to 3 months and can be planted in the field after hardening under shade for one to two months. Clonal propagation can be practiced in all the seasons but high success rate of rooting is achieved from June to September.
