Objective: To evaluate the effect of the application of biostimulant doses on the development, absorption, and use efficiency of nitrogen, phosphorus, and potassium by cacao seedlings. Design/Methodology/Approach: Five doses of Enerplant® (0, 1, 2, 3, and 4 mL ha-1) were applied to cacao seedlings grown under a saran mesh. The study was carried out...

... treatments were the biostimulant was applied obtained the highest mean values; they statistically surpassed the control (without biostimulant applications) or their results were statistically similar. Overall, a dose of up to 2 mL ha 1 of the product significatively increased the growth indicator of the cacao seedlings during both years ( Table 2). ...Context 3
... tallest cacao seedlings were obtained with the application of 2 mL ha 1 doses of Enerplant ® ; however, these results were not statistically different from those achieved with the application of 1 mL ha 1 doses of the biostimulant, a treatment which significantly increased height in 2019 and 2020 (25% and 22% more than control, respectively) ( Table 2). A downwards trend for this indicator was identified when higher doses were applied (3 and 4 mL ha 1 ). ...Context 4
... higher dry mass values were recorded with the 2 mL ha 1 (2019) and the 1 mL ha 1 (2020) doses (37% and 22% more than other treatments, respectively). Likewise, a downwards trend for the height variable was recorded when higher biostimulant doses were applied (Table 2). Gonçalvez et al. (2018) explain that the ideal balance for the growth of different vegetative organs is variable: a certain endogenous concentration of a given nutrient might favor the growth of one organ and inhibit the growth of another. ...Context 5
... were statistically superior to every other of the study treatments (109% and 7% increases during the first and second years, respectively). The 4-mL dose of the biostimulant reduced this indicator during the second year by 17%, compared with the treatment without application (Table 2). ...Similar publications
This research was conducted in Cingkam Mekhanggun Village, Lawe Alas District, Southeast Aceh Regency with a height of ± 250 meters above sea level. This research will be carried out from September 2020 to December 2020 with the aim of being able to determine the effect of manure and the correct dose of urea fertilizer in order to obtain the growth...

... Las algas marinas, es otro bioestimulante considerado como una excelente fuente de polisacáridos, glicerol, micro y macro nutrientes (El Khattabi et al., 2023), así como hormonas de crecimiento, los cuales favorecen el desarrollo de las plantas (Pérez, López, & Reyes, 2020). Los estudios anteriores destacan la utilidad de los bioestimulantes para el rendimiento, especialmente por el beneficio de asimilar nutrientes en el cultivo que influyen sobre la producción (Bustamante González et al., 2022), como el uso de bioestimulante a base de Silicio los cuales ayudan a disminuir la influencia de la salinidad sobre los cultivos (Bantis & KouKounaras, 2023) o como herramientas modernas para la agricultura (Hung et al., 2023). Los resultados de la investigación apuntan a la eficacia de los bioestimulantes, contribuyendo a reducir los daños en las plántulas de cacao en vivero, mejorar la supervivencia y para aumentar la productividad. ...
Biostimulants help cocoa plants to improve vegetative development and nutrient uptake, therefore, the objective was to evaluate the effects of biostimulants on morphological growth in cocoa seedlings in nursery stage, through a completely randomized experimental design with four treatments (T1: control, T2: humic acids + fulvic acids, T3: silicon oxide + monosilicic acid; and T4: marine algae + humic and fulvic acids) and four replicates. The results showed no significant differences in variables such as plant height (T4: 29.63 cm), number of leaves (T2: 25.19) and root length (T2: 37.23 cm). Significant differences were found in stem diameter (T3: 7.08 cm) and root dry mass (T4: 8.67 g). The biostimulants showed positive results in nutritional elements at foliar level, improving the values of N, P, K, Zn, Mn, Mg, Ca and Fe. Likewise, there was a decrease in Cu and Na values. These results support the hypothesis that biostimulants help cocoa plants to improve vegetative development and nutrient uptake, reducing plant losses and improving plant nutrition at the nursery stage.
