Effect of pruning over the physiological and productive performance of the oil palm on the Colombian Northern Zone
In Colombia, the pruning of leaves in the oil palm cultivations is carried out applying technical concepts developed in latitudes that have environmental conditions different from the zones where the crop is developed in the country and consequently its practice does not often favor the crop's productivity. The following are the objectives of this experiment: to evaluate the effects of three levels and two frequencies of pruning on the yield and quality of the bunches and determine the critical foliar area of the oil palm under local environmental conditions. The research involves experiments in the Northern, Western and Eastern Zones, whose environmental conditions differ greatly. This document presents the yield results of fresh fruit bunches (FFB), the quality of the bunches and the oil yield per unit of cultivated area achieved in 43 months of work in the Northern Zone, where two frequencies are evaluated (monthly and by semester) and three levels of pruning (36, 30 and 24 leaves per palm). Highly significant effects were found as far as the number of leaves per palm in the production of FFB and in the potential yield of oil per hectare. Severe pruning, leaving only 24 leaves per palm, diminished the production of FFB significantly, as well as that of oil per hectare. Even though the difference may not be statistically significant with the control treatment of 36 leaves, it is more appropriate to maintain 30 leaves per palm, which increased the yield of FFB and of oil per unit of planted area. Among the quality parameters of the bunches, only the oil/bunch relation had a small combined effect of the treatments which favored the rate of extraction in the recurrent pruning treatments, specially up to the 24 leaves per palm level.
