Efeito, no primeiro ano agrícola, da época de poda e do espaçamento sôbre a produção de fôlhas de amoreira, de diferentes variedades, formadas pelo sistema de cepo: parte I - estudo na região de Pindorama

Preliminary results are presented in this paper of an experiment with Morus albaL. designed for the purpose of leaf production and laid out as a factorial 33 experiment (Cochran - 2 replications), in which were studied three common varieties of mulberry trees : Calabreza, Fernao Dias and Lopes Lins, same being grown and shaped through the "cepo" system and planted in the three spacings 1.5 by 1.0, 1.5 by 1.5 and 1.5 by 2.0 meters, the pruning time having been in three different seasons, i. e., June 10, June 30 and July 20. The first crop year (1964/1965) proved that this trial, installed at the Experiment Station of Pindorama, of the Instituto Agronomico, showed the best production of leaves obtained with the variety Calabreza, when using the 1.5 X 1.0 m spacing and the latest pruning season, namely July 20.
