To have organic coffee select good seeds

The process begins with selecting the coffee species suitable for the local climate.

Arabica coffee does well at higher altitudes, while robusta coffee grows better in hotter and humid areas, especially at lower altitudes. However, the prevalence of the berry borer and coffee rust are indicators as to whether the coffee variety is suited to the site conditions.

Select varieties which are resistant to common diseases like coffee wilt disease, coffee berry disease or coffee leaf rust.

Improved varieties can be obtained through local extension offices or coffee research stations.  

How to propagate the seeds

Most Ugandan coffee is propagated by seeds. Swizen Wamala, a famous coffee in Kagadi district says such coffee takes longer to grow than vegetative propagate coffee, which is called cloning.

According to Wamala, vegetative propagation has the advantage that coffee will carry all the qualities of the parent plant. Cuttings are obtained from selected mother gardens of desired varieties.

Coffee Handling

He says coffee plants raised from clonal cuttings bear fruits 24-36 months after transporting, whereas plants grown from seeds bear fruits after 48 months.

With post-harvest losses, the quality depends a lot on how well it has been picked, processed, dried, packed, and stored. To minimise contamination, until safe storage, it is, therefore, important to carefully harvest and safely handle the harvested coffee through primary processing activities.

Ponsiano Nyombi, another coffee farmer of Kamuzinda village in Masaka district says the quality depends on how and when picking is done from the field. Many farmers mix red ripe berries with shriveled, black, discoloured, and defective beans that break easily, are of inferior quality, small in size, and are usually eliminated as part of the husks during milling, resulting in qualitative and quantitative post-harvest losses. In addition, the immature beans give a bitter taste to the coffee.

Proper harvesting

-Carefully pick only mature red beans and leave the green ones on the tree to ripen further. Always pick, do not strip.

-Spread the coffee beans on a tarpaulin or soft sheet to dry, not directly on the ground. The sheets will ease the collection of all the beans and minimise the contamination of the beans.

-If they drop on the bare ground, the beans should be collected carefully.

-Remove all inferior or green bean leaves, twigs, and foreign matter for the harvested beans.

-Pick regularly, every after two weeks, to get good yields and better quality.
