Resumo
The objective of this study was to evaluate different methods of drying of leaves for three different fruit (passion fruit, peach and avocado), with respect to the determination of dry matter and foliar nutrients. Samples were collected from recently expanded leaves of three crops orchard Farm education and research FCAV-UNESP, Jaboticabal campus, in January 2010, by collecting 12 samples for each culture with 25 leaves. The treatments consisted of two drying methods, greenhouse circulation of air regulated to a temperature of 70°C and FMO. We evaluated the mass of dry matter and foliar nutrients. The results suggest that the two drying methods tested did not interfere in the determination of dry matter and foliar nutrients to crops analyzed, except the calcium levels in peach.
