Abstract

At present, food production is of considerable importance, particularly vegetables used as condiments and in the pharmaceutical industry. The application of biostimulants to enhance yield presents a promising alternative. This research aimed to evaluate the morphophysiological and productive responses of garlic to different biostimulants. The effectiveness of the biostimulants VIUSID Agro®, FitoMas-E, Effective Microorganisms, and a formulation consisting of a mixture of all these was evaluated based on their differing compositions. Morphophysiological parameters such as bulb diameter, pseudostem diameter, number of cloves per bulb, growth rates, and yield, among others, were evaluated. The results revealed a significant increase in all morphological indicators with the application of the biostimulants. VIUSID Agro® had the greatest effect on bulb diameter, with a rise of 14.59% compared with the control group. In addition, the absolute growth rate showed an average increase of 0.032 g d-1 with this biostimulant. With regards to the net assimilation rate, the best results were obtained with VIUSID Agro®, Effective Microorganisms, and the combination of all biostimulants. Overall, VIUSID Agro® had the best performance in terms of morphophysiological and production parameters. These results suggest that the use of these biostimulants may be beneficial for increasing garlic production, which could be crucial in the current global food supply situation.
