Density and fertilizer requirements of the compact and disease resistant arabica coffee
A trial was set up using Catimor, the compact and disease resistant F3 generation from a breeding programme as the test crop. Catimor is similar physiognomically to the hybrid that the breeding programme aimed at releasing to growers later. Sixteen NPK fertilizer combinations and six tree densities were tried between 1981 and 1988. Yield differences due to fertilizer treatments were not significant. However, yields of over two tons per ha were obtained from NP or NPK combinations. Yield increased linearly with the tree density but peaked at 5128 trees per ha. The results are discussed. It is concluded that while the fertilizer requirements for the compact cultivar are not different from the traditional tall types the optimal density is about 5128 trees per ha
