“…in the nursery phase, so that the dose of 500 mg of chitosan per liter of water improved the survival conditions of the seedlings, observing a possible negative effect when increasing the dose up to 1000 mg of chitosan per liter of water. This agrees with (Rivas-García et al, 2021;Reyes-Perez et al, 2022), who, at the tomato and cocoa nursery level, maintains that the application of 3000 mg L -1 and 1000 mg L -1 doses respectively of foliar Quitosan based products (Quitomax®) should be considered as one of the most important to guarantee success in obtaining seedlings, since that a higher dose could generate negative effects, as well as economic losses due to a waste of inputs.…”

Background: The sexual propagation of Cocoa (Theobroma cacao L.) has some limitations to preserve some desirable agronomic characteristics in successive generations. Objective: The present research evaluates the effect of a chitosan based-formulation (Quitomax®) on morpho-physiological, rooting attributes and benefit-cost ratio of two cocoa varieties during vegetative propagation. Methodology: The experimental design was completely randomized with a factorial arrangement (A × B), where A represented the two clones and B the three concentrations of chitosan based formulation used (0, 100, 500 and 1000 mg L-1), with three repetitions. per treatment. The survival (%), the stem diameter (mm), the number of leaves, the number and length (cm) of roots, the biomass (g), the gas exchange (A, gs, Ci, E), and an economic analysis of the two cocoa plant varieties were evaluated at 120 days after starting the trial. Results: The clone CCN-51 treated with 500 mg L-1 had significantly the highest results on survival (80%), stem diameter (6.83 mm), number of leaves per plant (8.2), number and length of roots (6.21 and 35.74 cm), aerial and root biomass (4.07 g and 1.64 g) parameters. In gas exchange, the highest values of Water use efficiency (WUE) were observed at 500 mg L-1 in CCN-51 (5.36 mmol mol-1) and 1000 mg L-1 in INIAP-EETP-801 (7.62 mmol µmol-1). In both clones, higher profitability was obtained when applying the chitosan dose of 500 mg L-1, reaching profitability of 40.65 and 50.00% for clones INIAP-EETP-801 and CCN-51, respectively. Implications: The cocoa clone CCN-51 showed plants that exhibited greater development of both the aerial part and the root part of the cocoa seedlings than INIP-EETP-801 coca clones. Conclusion: The chitosan based formulation at 500 mg L-1 is a promissory alternative to improve the evaluated parameters after 120 days of cocoa vegetative propagation.

“…An increase in the fresh biomass of tomato fruit and root was reported in response to the application of chitosan (Chanaluisa-Saltos et al, 2022;Rivas-García et al, 2021). The diameter of the broccoli head variety italica, also increased in response to chitosan (Yildirim et al, 2011), in contrast, Kałużewicz et al (2018) found no effect on this variable in response to the application of an amino acid as a biostimulant in broccoli of the variety Tiburon.…”

Biostimulants improve the absorption and assimilation of nutrients by plants, making them more tolerant to biotic or abiotic stress, improving their agronomic characteristics. Natural and biodegradable biostimulants such as chitosan have fungal and bactericidal activities and promote growth and crop yield, this is why, to evaluate the effect of chitosan application on growth and productive parameters of broccoli (Brassica oleracea L.), three concentrations of chitosan (T1 = 500 mg.L-1; T2 = 1000 mg.L-1; and T3 = 2000 mg.L-1) and a control treatment (T4 = distilled water), were applied by foliar spray when the true leaves unfolded, using a completely randomized design with 30 repetitions per treatment. The variables height of the plant, number of leaves per plant, diameter of the flowering stalk, diameter of the flowering head, length of the flowering stalk, total length of the flowering stalk, fresh biomass of the flowering head, of the root, and of the aerial part, total dry biomass and yield were measured. All the variables increased (P<0.05) as the chitosan dose increased, concluding that the application of chitosan to the broccoli crop is a viable alternative as a substitute for synthetic fertilizers.

“…Likewise, López et al, 57 obtained higher growth and production in tomatoes treated with chitosan at a concentration of 300mg/L compared to tomatoes without chitosan, because chitosan increases the chlorophyll content in the leaves. While Rivas-García et al, 73 in two tomato varieties increased yield. 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.…”

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.
