Get PDFEffect of planting density on the yield of coconut
Get PDFAn analyses is presented of the yield components of coconut established under densities varying from 128 palms/ha to 239 palms/ha from a spacing trial conducted by the Coconut Research Institute. Analysis of yield data during 1976-1980 from 24 palms from 4 replicates analysed for each density treatment revealed significant differences in nuts/palm and copra/palm for the densities tested. The nuts/palm decreased with increasing density but the yield/ha, maximised at a density of 171 palms/ha and decreased beyond 171. Significant differnces were absent inyield of copra/nut for the densities tested. The differences in copra/palm were due to the effect of nut number/palm. At a densityof 179 palms/ha, copra/ha maximised to 2260 kg and decreased beyond 179. The results of the present analysis indicate that a density ranging from 171-179 palms per hectare is the optimum for planting coconut in dry-intermediate zone where the study was conducted
