EVALUATION OF DASOMETRIC VARIABLES OF SPROUTS OF Eucalyptus camaldulensis DEHNH, AT THE EXPERIMENTAL FARMS EL PLANTEL, NINDIRI, MASAYA

Abstract

The assessment study of the capacity of regrowth of Eucalyptus camaldulensis Dehnh, is aimed to evaluate the behavior of sprouts into plantations by implementing pruning silvicultural treatment in areas that have been exploited. The methodology used consisted of establishing a field trip in the plantation of eucalyptus in the experimental farm el Plantel, for the purpose of selecting areas for establishing plots in areas that had been previously exploited. After selected the plots, we proceeded to the selection of the sprouts, from which, the most vigorous with straight trunk were selected, as well as, the best three axes of the stumps. Data collection in the field was performed by evaluating the following variables: stump height greater than 20 cm, stump height less than 20 cm, stump diameter of 5 cm and stump diameter between 15-20 cm. Silvicultural treatments had an influence on the increase of height and diameter growth in the shoots, weed control, the remove of vines and thinning of sprouts, favoring them in the absence of competition for the selected sprouts. According to statistical analysis t Studen, the variable stump less than 20 cm in height, is the best performing variable for the future management of the shoots. The plants survival in the plots established independently of the four variables that were applied, is good according to the classification used in the experiment. It is recommended to continue applying silvicultural treatments for better performance in both diameter growth and height of the sprouts.
