Abstract

An experiment was conducted from August 2014 to January 2015 to determine growth responses of four Robusta coffee (FRT 7, FRT 11, FRT 23 and FRT 65) seedlings to different shade and fertilizer levels. Different shade levels (30%, 55%, and 90% shade) were imposed to coffee seedlings using black fish nets, while fertilizers were provided at varying amounts: 0% of the recommended rate (RR), 100% RR, and 200% RR. Results showed that FRT 23 seedlings, regardless of shade and fertilizer levels, and seedlings provided with 200% RR, regardless of genotype, exhibited high mortality within one month after transplanting. On the other hand, maximum vegetative growth, in terms of plant height, number of nodes, number of leaves, distance between nodes, relative greenness of leaves, leaf area, stem diameter, rooting intensity and seedling vigor, was observed in FRT 7, FRT 11 and FRT 65 seedlings grown under 30% shade and 55% shade, and provided with 100% RR. Correlation analyses suggest that shading is negatively related to plant height, stem diameter and rooting intensity, while fertilization is positively related to leaf area and relative greenness of leaves . Another experiment was conducted to determine the effect of fertilizer (0% RR, 100% RR, 200% RR and 300% RR) on the growth and development of berries of three coffee genotypes (FRT 7, FRT 17 and FRT 65).
