AVALIAÇÃO DO DESEMPENHO DE CLONES DE Eucalyptus spp. EM SISTEMA DE INTEGRAÇÃO LAVOURA-PECUÁRIA-FLORESTA (ILPF) NO MUNICÍPIO DE MORRINHOS - GOIÁS

Abstract

Integrated Crop–Livestock–Forest (ICLF) systems represent a sustainable alternative for intensifying agricultural production in the Brazilian Cerrado. This study aimed to evaluate the silvicultural performance and genetic parameters of Eucalyptus spp. clones established under an ICLF system in the municipality of Morrinhos, Goiás, Brazil. The clonal trial was conducted at the Federal Institute of Goiás – Morrinhos Campus, using a randomized complete block design with 40 clones, seven replications, and five plants per plot. Evaluations were carried out at five years and two months (2023) and six years and three months of age (2024), assessing survival rate, circumference at breast height, total height, and individual tree volume. Statistical analyses were performed using mixed models via the REML/BLUP methodology. Mean survival reached 96.97%, indicating good adaptation of the clones to local edaphoclimatic conditions. High productivity and very high selective accuracy estimates (0.93 to 0.96) were observed. The results demonstrate the technical feasibility and productive potential of Eucalyptus spp. cultivation in ICLF systems under conditions similar to those of southern Goiás.
