Effect of the application of gibberellic acid, native microorganisms, trichoderma sp. and molasses in banana cultivation (musa x paradisiaca l).

The present research studied the incorporation of native mountain microorganisms (MM) in the foliar fertilization of banana crops in the template stage, with the purpose of improving environmental conditions, especially soil care and phenological development of the plant. . to allow continuous and healthy banana production. The study was carried out at the “Blanca Rosa” Farm belonging to the Dolé Company, located at Kilometer 23 of the Vía Babahoyo – San Juan. The investigation was justified because the income generated by the banana activity represents 3.84% of the gross domestic product (GDP), 50% of the agricultural GDP and 20% of the country's private exports. The second week after the template was transplanted, the first application of MM and Efficient Microorganisms (Trichoderma harzianum) (EM) was carried out. From the third week of sowing, the treatments were used; T1 (Absolute Control WITHOUT foliar treatment); T2(Commercial control, foliar + Ryzup combo); T3 (Commercial control, foliar combo + N-Large; T4 (Commercial control, foliar combo + Ryzup + native microorganisms); T5 (Commercial control, foliar combo + N-Large + native microorganisms); T6 (Commercial control, foliar combo) + Ryzup + Beneficial microorganisms Trichoderma harzianum); T7 (Commercial control (foliar combo) + N-Large + Beneficial microorganisms Trichoderma harzianum). The treatments were distributed in complete treatments at random, 7 treatments were established and each one with 4 repetitions, the experimental area was 1.2 Ha. To determine the statistical significance between the means of the treatments, the Tukey test was used with 5% of significance. The data evaluated were: foliar emission at (8, 15, 23, 30 daa), plant height (8, 23, 38, 79 daa), pseudostem circumference (79 daa), and economic analysis. With the results obtained, it is concluded that foliar fertilizations based on the application of commercial control, foliar combo, Ryzup and native microorganisms (T4) applied in this trial, present a significant effect and superior statistical differences between treatments for the variables studied: foliar emission and plant height (at 79 daa).
