Efecto de bacterias asociativas sobre el desarrollo de plántulas de banano

The present research about Effect of associative bacterium on banana seedling development was conducted in an area designed for field experiments in the Santa Inés experimental farm of the Faculty of Agricultural Sciences located in the parish El Cambio, 5 km from the road to Machala. The purpose of this research is to verify the contribution of nitrogen by bacterium in banana plantlets study to determine the effect of these and find appropriate ways to exploit their potential associations in nutrition, so we propose the following objectives: 1.To establishes the effects of bacteria in the nitrogen input on banana plantlets. 2. Perform cost analysis. The materials used, fine sand, plastic bags 0,3 x 0,4 m, scallions valery clone subgroup Cavendish banana, drip irrigation and plastic padding and bacterium TwinN. The treatments investigated were: T1 TwinN ground and foliage (sand) 12 +125 ml; T2 TwinN ground (sand) 125 ml; T3 foliage TwinN (sand) increased ten percent + twenty percent + thirty percent; T4 Witness (sand); T5 TwinN ground (earth) and T6. Witness (earth). The variables assessed were: Determination of total nitrogen in leaves to the thirty, sixty and ninety days. Measuring plant growth at 30, 60 and 90 days, weight biomass (root) end of the experiment. Number of leaves to the thirty, sixty and ninety days. Measurement of leaf area and pseudo stem diameter ten cm from the corm to the thirty, sixty and ninety days. The experimental design was assigned to the mathematical model completely randomized with six treatments and four replications, where the experimental unit was the seedling. Each seedling was taken to determine the variables indicated the study objective. Applying TwinN formulated nitrogen-fixing species with a fermentation process and subsequent lyophilization, influenced the growth in plant height after sixty days, as in the emission of leaves. In Twin treated plants, the rate of increase of the height was greater than that in the controls. In the sheets showed greater width and length and significant increase in root biomass. The foliar nitrogen increased to 4,18 to 4,42 ppm exceeding seventy six percent and ground control at least fourteen percent over sand substrate.
