The herbicides were effective only in reducing the weed growth as indicated by the lower fresh weight of weeds in the herbicides treated plots. The suppression in the growth of weeds by weedicides did not improve the nut yield. This reveals that weed control alone is not important in increasing the nut yield. On the other hand, ploughing the entire area enhanced the nut yield as much as 21% over control. This led to the conclusion that ploughing regularly in coconut gardens will improve the nut yield.  aCocos Nucifera  aCoconut  aCoqueiro1 aRAMANATHAN, T.1 aVIJAYARAGHAVAN, H.  tIndian Coconut Journalgv. 16, n. 4, p. 17-20, ago. 1985.
