Summary

Three experiments and five small trials on robusta coffee and four small trials on arabica coffee have confirmed that nitrogen is the main nutrient requirement in Uganda. Magnesium and sulphur were not deficient and mulching had no effect on responses to nitrogen fertilizers. Leaf and soil analyses confirm the yield results and indicate that the optimum time to apply nitrogen is in February and September. There was little difference between ammonium sulphate and urea, but the former tended to have greater effects on yields.
