The experiment was done at the Credit and Services Cooperative (CCS) “Juan de Mata Reyes”, in Pedro Betancourt municipality, Matanzas. The objective was to evaluate the effectiveness of indigenous microorganisms (IMO) preparations on the growth of onion (Allium cepa L.), variety Texas Early Grano. Five treatments were studied (control, a 2 mL.m2 treatment before transplantion, a 4 mL.m2 treatment before transplantation, and both 2 and 4 mL.m2 treatments 20 days after transplantion). The experiment was conducted in a randomized block design. The professional statistical pack STATISTICA, version 6.0 for WINDOWS was used for data processing. The results were statistically processed using simple analysis of variance and the Duncan´s multiple comparison Test for media with a level of significance of pd”0.05. The native microorganisms in the preparations were characterized. 60 days after transplantation, the parameters height of plant, number of leaves and diameter of the false stem were evaluated; and at harvest time, the total yield (t.ha-1) and the number of bulbs in diameter category were determined. The best results concerning the height of the plant (cm), diameter of false stem (mm) and total yield (t.ha-1).were obtained with the preparation of 2 mL.m2 at the moment of transplantion, and 20 days after the application.
