Assumption

This production forecast is made based on the assumption that:

  • Research Recommendation of the National Coffee Research Center at Jimma is considered as a base to estimate the level of ‘full capacity production’ (the maximum attainable  yield level from one hectare of land at full maturity)
  • Current Experiences and recommendations of Gumer coffee plantation (a state farm which is located adjecent to this project) is also considered for practical yield estimation.

According to information obtained from Jimmaa  National Coffee Research Center, improved coffee varieties yields between 15 – 20 quintals  of clean coffee per hectare of land at full maturity. There are also three recently released varieties of coffee which gives up to 26 qt./ha. Taking a yield level of 20qt/ha as a base,  the maximum yield level for this project is calculated to be 16qt./ha . This is taken by considering the 20qt/ha as a yield level at an ideal environment (A yield level achieved by Research Centers), then assuming 80% of  the  experimental level is achieved by this project. This  maximum yield  will be attained  on year 13 after a progressive increase from year 4 -12. The yield starts at 6qt/ha on year 4, after a gradual increase in subsequent years, it reaches 16qt/ha on year 13.

Accordingly,  a total of 240 qts. of clean coffee bean will be  collected on the 4th year,  thus  through progressive annual increase in productivity (yield/ha), about 4,770 quintals of clean coffee will be collected on 13th year. In sum, a total of 41,590 quintals of clean coffee is expected from the project in its entire project life, which is 16 years.
