“…Reyes-Pérez et al, 68 with the application of chitosan at a dose of 2g/L-1 in two tomato varieties, increased the percentage of germination, growth and yield; because chitosan increases photosynthesis, chlorophyll synthesis induces stomatal closure for more efficient use of water, in addition, chitosan degradation generates ammonium, a source of plant nitrogen. There are other references to the stimulating action of chitosan in a wide variety of agricultural crops: such as Phaseolus vulgaris, 74 in tobacco, 75 in Oriza sativaor rice, 72,76 cucumber, 68 halophytic plants such as S. bigelovii, 35 in Sorghum vulgare, 17 , turnip 77 and cocoa. 68…”

Mexico is considered one of the main vegetable producing countries, however, its production is affected by several phytopathogens, whose control of these pathogens is based on the use of agrochemicals, which cause consequent environmental and health damages. In 2018, Mexico ranked 5th in the world in the consumption of fungicides and bactericides in agriculture. For this reason, new alternatives to control phytopathogens are important, with natural compounds with antifungal properties such as chitosan, a biopolymer of N-acetyl-D-glucosamine and D-glucosamine units linked by β-(1-4) bonds derived from the deacetylation of chitin with alkalysis (NaOH) or enzymatic hydrolysis. Chitosan is extracted from exoskeletons of arthropods. Research shows that it inhibits the growth of phytopathogens, due to its polycationic nature depending on molecular weight and deacetylation percentage. With other antifungal properties, they are inducer of phytoalexins, promotion of plant growth and biostimulant of beneficial microorganisms, due to its useful and economic potential agricultural application in technological innovation.

“…El quitosano podría representar una alternativa viable para aumentar los rendimientos, reducir la contaminación ambiental por el excesivo uso de fertilizantes y pesticidas además de producir alimentos más inocuos con menos riesgo para el consumo humano, a esto se suma la ventaja de reducir los costos de producción y de esta forma mejorar la calidad de vida de los agricultores (Reyes et al, 2019;Torres et al, 2018).…”

La agricultura actual busca productos que permitan el crecimiento y desarrollo de los cultivos, así como incrementar los rendimientos, asimismo que los principios activos sean de origen natural, biodegradables y no causen danos al ambiente. El propósito de esta investigación fue evaluar el efecto de la aplicación de quitosano en dosis de 1, 2 y 3 g.L-1 en la emergencia, desarrollo y rendimiento de las variedades de tomate Floradade y Amalia, en condiciones de invernadero. El diseño experimental fue un Bloques completos al azar, con arreglo factorial 2 x 3 + 2. Los resultados mostraron que la dosis de 2 g L-1 fue la que mostro los valores mayores en la emergencia y desarrollo de las plantas de tomate, estimulo una mayor fructificación, peso de frutos y mayor rendimiento en la variedad Floradade. A esto se concluye que la aplicación de quitosano en dosis de 2 g.L-1 en las condiciones que se realizó la investigación incremento los rendimientos del cultivo de tomate en la variedad Floradade.

The application of biostimulant in agricultural practices is a promising alternative to the use of chemical pesticides that harm the health of man and the environment. The objective of this work was to evaluate the effect of the foliar application of the biostimulant Quitomax at concentrations of 200, 400, and 600 mg·ha-1 on some phenological phases of cowpea plants, as well as indicators of growth and agricultural yield of this legume. The sowing was done directly, in a double row with a planting frame of 0.70 x 0.40 m on a bio-fertilizer substrate and sandy soil. The application of Quitomax was carried out at the beginning of flowering. A randomized block experimental design with four replicates per treatment was used. The growth indictors, length and diameter of the pods, pods by plants, fresh pod mass and grains by pods, as well as the yield were evaluated. It was found that the highest concentration of Quitomax applied 600 mg. ha-1 produced significantly cowpea plants with higher growth and yield indicators than the rest of the treatments.
