The division of Agronomy and its units at different
regional stations is actively engaged in developing suitable agro-techniques
based on soil, land, water, shade and weed management aspects for increasing the
productivity of various coffee varieties under different agro-climatic
- Standardization of soil management practices for
conserving the soil and moisture.
- Bush management practices like optimum spacing
, planting, design, training and pruning for achieving consistent yields.
- Irrigation management using sprinkler and drip
methods for overcoming dry conditions and for assured crops through blossom
and backing irrigation.
- Efficient and cost effective weed control measures.
- Shade management for optimum performance to
different fertilizer doses.
- Drip irrigation during dry months from November to
May was found to be beneficial in Cauvery. Application of 4 litres of
water per day for about 100 days during the dry period resulted in yield
increases up to 24 percent with a cost benefit ratio of 1:1:5. However
high initial investment, regular maintenance etc. makes it unsuitable for
- Ground micro-sprinkler irrigation in robusta was on
par with overhead irrigation but has the same limitations as that of drip
irrigation and hence not suitable for large areas.
- A commercial bio-fertilizer 'Biophos' (containing
phosphorus solubulising micro-organisms ) @ 10 kg./ha. increased yield of
arabica by 39 percent with saving in phosphorus nutrient up to 30 per cent.
- Bhumilabh, an organic manure, @ 30 gms. per basket
seedling of C X R and Cauvery in the nursery ha boosted their growth to the
point of transplanting to the field. "Green Plus" another
commercial manure had increased the yield of robusta by about
200 kg. per ha. when applied @ 5 kgs. /plant/year compared to recommended
doses of inorganic fertilizer. However the yield increases was not
commensurate with the cost. This may be of use in production of
- Spark, a test product containing glyphosate ( post
emergent systemic weedicide ) @ 1.08 kg.a.i per ha.( 2.5 liters of
formulation per ha. ) was as effective as other recommended glyphosate
- Case study on organic coffee farming conducted in a
private estate indicated that it is possible to cultivate arabica coffee
organically without any yield reduction.
- Economy in water requirement through micro

- Integrated use of organic chemical and
bio-fertilizer towards sustainable nutrition management.
- Evolving low cost technologies.
- Developing weather forecast models for predicting
out-break of pests and diseases.
- To develop agro-technique for organic coffee
