Forma e tamanhos ótimos de parcelas experimentais de eucalipto clonal em sistema de integração – lavoura – pecuária – floresta

Abstract

Were conducted in EMBRAPA Agroforestry in Sinop - MT, nine tests of uniformity in integrated crop livestock forest (iLPF) system and an essay in pure stand coded as (P.Puro, iLPF1, ILPF2, iLPF3, iLPF4, iLPF5, iLPF6, iLPF7, iLPF8, iLPF8 and iLPF9). The dendrometric variables analyzed were: the diameter at 1.30 m above the ground ( DBH ), total height (HT) and bark volume (Vol). For each of these variables was set a great size and a suitable form of plots. Among the three variables dendrometric the one with the largest plot size was chosen as the most appropriate for determining the size used for each area. The basic unit (BU) was considered a plant / tree. Was used to BU's conveniently arranged in rows and columns, 17 different sizes of plots (ixj) and (1,2,...,14,15,20 and 25 plants per plot), formed by basic units in row i and j basic units in the column were simulated. Estimation methods were. Modified maximum curvature method ( MMC ) method of linear model response plateau (LMRP) and method of quadratic model response plateau (QMRP), to check the difference between the quality of the adjustments, the coefficient of determination (R²) , information criteria of Akaike (ICA) and the information criterion of Bayesian (ICB). Methods were compared the best way corresponds to the conformation that provides the lowest ( CVX ) most IR.Com the results it can be identify that among the methods evaluated the best method is the MCM; and among the variables analyzed (Vol ) was chosen for being the most demanding . (P.Puro) to this reality and (iLPF6) areas the plot size is 8 UB and other areas of that same reality 7UB and rectangular plots were those that are most appropriate.
