    Currently, the application of biostimulants in crops is one of the methods that allows the stimulation of seed germination, increase its development, and improve harvest efficiency. The present research work was developed in the Agua Santa neighborhood, belonging to the Tisaleo Canton, with the purpose of evaluating the Fertumax Biostimulant, based on cytokinins and seaweed Ascophyllium nodosum, Sargasum sp. and Laminaria sp. In this experiment, 3 different doses of the Biostimulant were evaluated, (1.5 cc/l; 2.5 cc/l and 3.5 cc/l) and a control without Biostimulant, the application was made to the seed and in the flowering stage. A completely randomized block experimental design (DBCA) was executed, with 3 treatments and 4 repetitions plus 1 control, and analysis of variance (ANOVA) and Tukey's test at 5% were applied. The application of D2 (FertuMax 2.5 cc/l), was the treatment that presented significant statistical differences, therefore, it positively influenced the variables of height at 30 days, number of grains per pod, weight of pods and yield in green, obtaining means of 7 cm, 6.43 grains per pod, 597 g and 0.60 kg, respectively. In the variables germination percentage, plant height at 60 and 90 days, when performing the Tukey test at 5%, it was obtained that the results are statistically equal, however, it presented numerical differences, the best treatments were with 92 .75% for treatment D2 (FertuMax2.5 cc/l) and D3 (FertuMax3.5 cc/l), 16.50 cm and 37.75 cm, respectively

    Evaluación de un biofertilizante a base de rhizobium en la producción del cultivo de arveja (Pisum sativum L.) variedad temprana perfecta

    The pea crop is one of the main grains grown in Ecuador, and is the third most important legume crop in terms of production and area planted. The present research sought to improve the yield of the pea crop (Pisum sativum L. ) variety Temprana Perfecta, for this purpose, a biofertilizer based on Rhizobium was developed and its effectiveness was evaluated through treatments with different doses (25cc/L, 50cc/L and 100cc/L) and frequencies (8 and 15 days), the trial was conducted in open field, but not clearly in situ, This is to say that the crop was established in potting bags with commercial substrate, because when working with a fertilizer whose main composition is a bacterium, a soil in which the presence of other microorganisms had not been found was needed, thus avoiding any alteration in the rhizosphere of the crop. After the application of the biofertilizer on the crop, data were collected in three different phenological stages of the plant, vegetative development (45 days), flowering (60 days) and green production (95 days), these stages are according to the variety (Temprana Perfecta), since this is early, i.e. its production is before the usual time. The treatment with which the best results were found was variant, both in the phenological stages and in the morphoagronomic characteristics of the crop, but the one with which an excellent yield was obtained was D3F1 (100cc/L, 8 days), with a green production of 7920.40 kg/ha. This was a sufficiently favorable result in the research.

    Evaluación de un biofertilizante líquido a base de excretas de cerdo en la producción de arveja (Pisum sativum L.) Var. Quantum
    (2020-01-22) Arévalo Freire, Andrés Stalin; Muñoz, Manolo
    The objective of this research was to evaluate a liquid biofertilizer based on pig excreta in the production of peas (Pisum sativum L.) A randomized complete block design with 4 repetitions was used. 3 doses were used at 3 different frequencies, using a control. The application of biofertilizer based on pig excreta was carried out every 5, 10, and 15 days with their respective doses from 20 days after the germination of the plants, up to 15 days before harvesting, triple fifteen was applied to the control, what the farmer frequently applies. Significant differences were observed on the variables plant length, number of pods, pod weight and yield. The treatment D2F2 (16,17 liters of bowl / liter of water every 10 days) was the best treatment, with encouraging results 70, 25 cm in plant length, 34,74 number of pods per plant and 175 g weight of green pods Regarding the witness who had 47.75 cm in plant length, 15.72 pods per plant and 83,75 g weight of green pods. The best performance achieved was 11666,67 kg.ha−1. This indicates that the mentioned variables were positively affected by the application of the biofertilizer. Keywords: P. sativum, plant length, number of pods per plant, pod weight and yield
