climate requirement for coffee

• Coffee is more exacting in its climatic requirement than its soil requirements.

  Important climatic parameters deciding coffee performance and production

  1) Rainfall
  2) Temperature
  3) Humidity
  4) Altitude

 

 

Sl. No.	Climatic Factors	Arabica coffee	Robusta coffee
1.	Absence of blossom showers during	March- April	March
2.	Absence of backing showers during	Delayed beyond one month after blossom showers – Poor crop set	Delayed beyond 20 to 25 days after blossom rain - Poor crop set
3.	Hail storms	Injures floral and vegetative parts	Same damage as in arabica coffee
4.	Rain on the day of blossom	Partial or complete failure of the crop	Partial crop failure
5.	Western/Southern Exposure ( with poor soil moisture)	Partial or complete failure	Partial crop failure
6.	Wind exposure	Sensitive	Sensitive

Rain fall for Coffee cultivation
Well distributed rainfall is preferred for coffee cultivation with dry months from December to March.

• Summer showers ===

  Important for flowering in coffee.

• Backing showers ===

  Coffee is shallow rooted crop and can not exploit soil moisture from deeper sub soils. Hence, for good fruit development backing showers is suggested.
