Abstract | Full Text

The research was done in the intensive-farming areas of the Cooperative of Credits and Services “Ramón Ruiz del Sol”, in Los Arabos, Matanzas. The objective was to evaluate the application effects of effective microorganism (EM) and Trichoderma harzianum on the main growth indexes of onion seedlings (Allium cepa L.) during nursery stage. Six treatments were studied ( control, organic matter at 24 kg.m-2, T. harzianum at 30 g.m-2, Effective Microorganisms at 15 mL.m-2 at the moment of sowing and 15 and 30 days after the germination of the seeds, organic matter at 24 kg.m-2 + T. harzianum 30 g.m-2 + Efficient Microorganisms at 15 mL.m-2 at 15 and 30 days after germination of the seeds, and T. harzianum 30 g.m-2 + Efficient Microorganisms at 15 mL.m-2 at 15 and 30 days after the germination of the seeds. The experiment was arranged in a randomized block design. 55 days after seed germination, the height of the seedlings, number of leaves per seedlings, diameter of the false stem, root length, as well as the fresh and dry weight of the radical system and the foliate area were evaluated. The results proved that the Effective Microorganisms (EM) and T. harzianum application improved the production of quality onion seedlings. The treatment 5 (organic matter 24 kg.m-2 + T. harzianum 30 g.m-2 + Efficient Microorganisms at 15 mL.m-2 at 15 and 30 days after germination) had better results in the evaluated variables.
