“…For example, humic substances can directly affect the metabolism of plants by exerting an influence on the transport of ions, facilitating their absorption, increasing respiration and the speed of enzymatic reactions. This leads to greater energy production, increases the chlorophyll content, increases the synthesis of nucleic acids, the selective effect on protein synthesis and the increase or inhibition of various enzymes, resulting in a positive effect on plant growth (Reyes-Pérez et al, 2020;Shah et al, 2018;You et al, 2018).…”

This study evaluated the effect of HS extracted from mineral coal on the growth of tomato (Solanum lycopersicum) and melon (Cucumis melo) plants to determine the role that humic substances (HS) play as promoters of plant growth. Three concentrations of HS were evaluated in 200 grams of soil. The fertilizer (urea 0.3%) and humic acid in concentrations of 0.05%, 0.1%, and 0.2% were added directly and at the same time to the amount of soil, using a control sample without the addition of humic acid. Increase measurements were made at three-day intervals up to 45 days. Plants treated with high concentrations of HS demonstrated a significant increase in roots (p>0.05). In both plants, the concentration of 0.2% in HS showed the greatest increase in growth, with the melon plant showing the greatest variation as time passed, with its highest peak in 36 days (13.1 ± 0.05cm) of the experiment, while in the tomato plant the maximum growth occurred in 30 days (9.2 ± 0.01 cm). The Dunnett test showed that there was no statistically significant difference between the control and the concentrations of 0.05% and 0.1% (p>0.05), while among the control and the soil sample with a concentration of 0.2% there was a statistically significant difference (p<0.05). The results show a notable influence of humic acid on the growth of the studied plants, especially at high concentrations. Keywords: fertilizer, horticulture, humic acid, soils.

“…The response of all variables was directly proportional to the concentration of chitosan, in figure 1 it can be seen that the growth variables; plant height, stalk length, stalk diameter and the number of leaves, increased their response as the concentration of chitosan increased. Increases in plant height in response to chitosan application have been reported in tomatoes (Terry et al, 2017;Reyes-Pérez et al, 2020a;Chanaluisa-Saltos et al, 2022), turnip (Álvarez et al, 2021), rice (Molina et al, 2017) and broccoli but using a vegetable protein hydrolysate as a biostimulant (Amirkhani et al, 2016). The biostimulant effect of chitosan on crop growth is related to the increased availability and absorption of nutrients and the process of photosynthesis through the accumulation of metabolites and the increase of foliar pigments (Sharif et al, 2018).…”

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.

“…At the end of the experiment, stem thickness was very similar among the microorganisms and was 27 % greater than the control. Reyes-Pérez [33] cite increased stem diameter in Floradade and Pomodoro tomato varieties inoculated with Glomus mosseaes and also in tomato var "Rio Grande" inoculated with R. irregularis [34]. Similarly, Ley [35] reported a significant increase in stem diameter when inoculated with autochthonous fungi, Glomus clarum and Glomus intraradices.…”

The “tomato” Lycopersicon esculentum M (Solanaceae) is a vegetable with a high demand for consumption. For its production, plant nutrition is traditionally based on agrochemicals. Currently, nutrition alternatives are being sought based on various soil microorganisms that in combination with organic amendments, such as poultry manure, can improve the physical, chemical and biological properties of the rhizosphere. In this study, the effect of the application of two beneficial microorganisms, Rhizophagus intraradices and/or Azospirillum brasilense and poultry manure to the substrate in L. esculentum M was evaluated. The experiment was carried out in a greenhouse and the plants were established in bags with the following treatments: 1. control, 2. R. intraradices, 3. A. brasilense, 4. R. intraradices + A. brasilense. Morphological and physiological yield components were recorded 84 days after transplanting. Plant height, stem thickness, number of leaves, flower bud, flowers and dry biomass of leaf, stem and root, weight of fruits were analyzed statistically and differences between treatments were compared according to Tukey (p ≤ 0.05). In conclusion, the results indicate that L. esculentum M. in the nursery with some of the microorganisms individually and in co-inoculation, favored the growth and dry matter allocation of the morphological and physiological components of the yield compared to the control. The number and weight of fruits increased with co-inoculation of R. intraradices and A. brasilense.
