RESUMO. O uso de resíduos agrícolas como alternativa na formulação de substratos é uma possibilidade relevante na produção de mudas, reduzindo simultaneamente custos e o acúmulo desses subprodutos no ambiente. O objetivo desse trabalho foi avaliar o potencial de substratos compostos por resíduos da produção de café para o desenvolvimento de mudas de Joannesia princeps Vell. O delineamento experimental foi inteiramente casualizado com três tratamentos em oito repetições, com 14 mudas por parcela (formulado 1: 10% vermiculita e 90% fibra de coco; formulado 2: 10% vermiculita, 30% casca de arroz carbonizada e 60% fibra de coco; formulado 3: 10% vermiculita, 30% casca de café carbonizada e 60% fibra de coco; fertilizados com 4000 g m-3 de Osmocote®). Foram realizadas avaliações de altura e de diâmetro do coleto das mudas aos 150 dias e aos 210 dias após a repicagem das mudas para tubetes. Não foi observada diferença estatística significativa ao nível de tratamento. A casca de café carbonizada se apresenta como componente alternativo à casca de arroz carbonizada para a formulação de substrato para a produção de mudas de J. princeps. TITLE. Coffee waste reused as an alternative substrate for the production of Joannesia princeps. ABSTRACT. The use of agricultural residues as an alternative in the formulation of substrates is a relevant possibility in the production of forest species seedlings, reducing simultaneously the costs and the accumulation of these products in the environment. The objective of this work was to evaluate the potential of substrates composed of coffee production residues for Joannesia princeps Vell. seedlings development. We used experimental design entirely randomized with three treatments in eight replications with 14 seedlings per plot (formulate 1: 10% vermiculite and 90% coconut fiber; formulate 2: 10% vermiculite, 30% carbonized rice peel and 60% coconut fiber; formulate 3: 10% vermiculite, 30% carbonized coffee husk and 60% coconut fiber). The substrates were fertilized using 4000 g m-3 of Osmocote®. Evaluations of the seedlings height and diameter were carried out at 150 days and 210 days after the transplanting of the seedlings into tubes. There was no statistically significant difference in the treatment level for the two evaluations. Carbonized coffee husk is presented as an alternative component to carbonized rice husk for substrate formulation in the production of J. princeps seedlings. MenosRESUMO.

The n-alkanes have been used to estimate forage dry matter intake, digestibility and the diet composition in grazing animals. The objective this study was to compare chromium oxide and nalkanes techniques used to estimate forage intake. Twenty lactating dual-purpose cows receiving two sources of fat (treatments: conjugated linoleic acid (CLA) or Megalac (control)) plus 4 kg of concentrate were dosed with n-alkanes and chromium oxide to estimate the intake of stargrass (Cynodon nlemfüensis Vanderyst var. nlemfüensis). The in vitro dry matter (DM) digestibility of the stargrass and concentrate were used to estimate the nutritive value of the digesta. The n-alkanes between C23 and C36 were quantified in the digesta and feces. The regression between metabolizable energy requirement (MEr, Mcal d-1) and supply derived from forage DM intake estimated using chromium oxide was ME IntakeCr = 19.1 + 0.62 MEr (R2 = 0.27) and the same relationship estimated using C35:C36 n-alkane ratio was ME IntakeC35:C36 = 9.3 + 0.77 MEr (R2 = 0.52). There was a treatment effect on fecal concentration of chromium oxide with daily and period variations. For the n-alkane technique, treatment and period effects and a linear effect of day of collection on the fecal concentrations of C35 were found. For C36 fecal concentrations, there was a treatment effect and a quadratic effect of collection day. There was no treatment effect on the fecal concentration of the C35:C36 ratio, but a period effect and a linear effect of day of collection were found. Estimates of daily intake using the two markers were different, but those obtained using the C35:C36 pair of n-alkanes were more precise than those obtained using chromium oxide and in vitro digestibility. Management of experimental animals could have influenced the concentration of markers in the feces, determining variations and inconsistencies that partially explain the inaccuracy of the estimates MenosThe n-alkanes have been used to estimate forage dry matter intake, digestibility and the diet composition in grazing animals.
