The inoculation of plant growth-promoting microorganisms was evaluated on the growth, development and agricultural yield of broccoli under greenhouse conditions. A completely randomized design was used, with five treatments and ten replicates each, which were: Azotobacter, Azospirillum, Pseudomonas, chemical treatment and control, An ANOVA analysis of variance and Tukey's test at 95% codiscnfidence was performed on the variables: plant height, number of leaves, stem diameter, diameter of the pela, pella weight, plant weight, leaf area, chlorophyll content and yield. Statistically significant differences were found in all variables, with the chemical treatment showing the best results, As for Pseudomonas, Azospirillum and Azotobacter at the beginning of the experimental phase, they showed significant statistical differences between treatments, as did the conventional fertilizer. The results of the experiment demonstrate that the inoculation of plant growth promoting microorganisms is a viable alternative for plant growth, although it does not produce the same results as chemical fertilization. Key words: Microorganisms, growth, broccoli, Azotobacter, Azospirillum, and Pseudomonas sp. |
