In evaluating the effect of the chitosan on the growth of postures of tobacco an experiment was developed in an area located in the CCSF “Luis Ramírez López”, state of Granma, in the campaign 2013-2014, using the seeds of the variety Corojo 2006. The investigation was developed in stonemasons to open field, applying chitosan to a dose from 350 mg ha-1 to the 15, 20 and 25 days after the germination and a treatment control. A design was continued totally randomized with four treatments, and three repetitions by treatment, they were evaluated the variables: longitude of the leaves (cm), the width of the leaves (cm), height of the plants (cm), number of leaves (OR), the width of the shaft (cm), dry and fresh mass of the leaves and the root (g). Finally, it was carried out the economic valuation. The obtained data were evaluated through an analysis of variance of simple classification and a test of stocking comparison by Tukey. The obtained results allowed to reach the conclusion of the beneficial effect of the chitosan on the indicators of quality of the postures, benefiting the producing with 51 025.50 CUP ha-1 when the bioestimulant applies to the 25 days after germinating the seeds.
