Drought Management in Coffee
Wherever water is available, overhead irrigation by sprinkler system is adopted
to a greater advantage during November-January to keep the soil moisture level and
in February-April for ensuring blossom as well as backing, if necessary.
Plants affected by drought limit vegetative growth, show floral abnormalities and
poor fruit set resulting in reduced yield. Therefore, drought tolerance is an important
aspect of coffee productivity. Arabica coffee is more tolerant to drought than Robusta.
For inducing tolerance in Robusta the following nutrient solution can be sprayed
@ 1 litre per plant.
Nutrient in 200 litres of water
|
Urea
|
1 kg
|
|
Superphosphate
|
1 kg
|
|
Muriate of potash
|
750 g
|
|
Zinc sulphate
|
1 kg
|
Spraying schedule
1st spray: 45 days after the last rainfall (usually the 2nd fortnight
of January)
2nd spray: 30-45 days after the first spray
Foliar application of anti-transpirants like Ralli Dhan 110 @ 200 ml in 200 litres
of water (0.1%) is also useful for drought management in coffee.
