Desempenho fitotécnico de clones de Eucalipto, cultivados em diferentes adensamentos e consorciados com mandioca

Abstract

Among the species that have gained prominence in intercropping, eucalyptus has achieved high visibility in use in agroforestry systems in Brazil. This highlight is linked to some factors, such as species diversity, multiple utility for products and uses, accelerated growth and good regrowth capacity, excellent productivity and high adaptation to agroforestry systems, in addition to the economic factor, as eucalyptus has a large potential for revenue generation according to their harvest. Given the above, the objective was to evaluate the performance of the intercropping of two eucalyptus clones, grown in different spacings, with cassava grown between rows. The experiment was installed at Sítio São Clemente located in the rural area of ​​Macaíba municipality, in the Agreste region of Rio Grande do Norte. The treatments were mounted in triplicate rows of 100 m for each of the four densities (9 x 1.25 m; 9 x 1.5; 9 x 2.0; 9 x 2.5 m). Each of the three lines was distributed in a magnetic East-West direction, neatly, totaling 24 eucalyptus lines. The variables analyzed were: stem length (COMP), in meters, and stem diameter at breast height (DBH), in millimeters. In cassava the average yield of tubers (t ha-1) was determined. There was no significant effect of the densities on COMP and DAP at the evaluated age. Cassava yield gain trend was observed with increasing eucalyptus density in the row.
