Biometria e produção de palma de óleo no município de Castanhal (PA).

Abstract

The cultivation of oil palm (Elaeis guineenses Jacq) is an activity of the agro-ecological and industrial chain, with commercial exploitation period of approximately 25 years, production on a commercial scale. It begins three years after planting. Oil palm yield is about 3 to 8 times higher than that of most oilseeds. The objective was to evaluate the growth, dry mass accumulation (DM) and oil palm production (Elaeis guineenses Jacq) as a function of age, through the following variables: plant height, stem circumference, leaf number and length, yield of bunches and dry mass (DM) of each plant component for each age studied. Data were obtained by the destructive method in four plants for each age, in commercial cultivation located in Castanhal (PA), using a completely randomized design. It was observed that the highest biometric results were found in eleven-year-old plants, with an average of 45 leaves per plant, 275 leaflets per leaf, 1.46m height of the stem, 2.20m circumference of the stem, 17 bunches. per plant and 2431 bunches per hectare. The DM production in all plant components increased with age, and the largest amount corresponded to the highest age surveyed (11 years).
