Eficiencia del hidrogel en la germinación de semilla de tomate de mesa en la parroquia San Antonio de Ibarra, cantón Ibarra, provincia de Imbabura

SUMARY The present work is given as a contribution to remedy in part the lack of study and application of new technologies that are generated every day, technologies such as the Hydro gel "potassium polyacrylate" that by its water absorption capacity of up to 500 Sometimes its weight to later release it for the plant in extended periods of time, makes it important to study, check and discuss the results as in this case to check its effects as the only source of water in the germination of tomato seeds . As a methodology used in the present investigation, a light test was used to test the efficiency of the hydrogel in the germination of tomato seed. The execution of the aforementioned trial was carried out under cover in a greenhouse, to have a regulated environment, prevent evaporation and, the action of external agents, making a seeding of tomato seeds in 96-well plastic trays filled with a mixture of substrate (black soil, compost) and adding hydrated hydrogel After having concluded all the steps related to the research techniques, and considering the different evaluation parameters, the visual analysis resulted in the verification that the majority of seeds suffered a rot due to excess moisture in the first four days as it is substrate remained in a state of permanent saturation, the rest of the seeds that could germinate showed weak mars with thin and chlorotic stems being its germination percentage of 30.5%. It is concluded that the use of the hydrogel as the only source of moisture for germination or other use in the propagation of seedlings is insufficient to cover the water needs for a period greater than 10 days, the use of the hydrogel in the germination of tomato seeds of Table is inefficient since they are susceptible to decay due to excess moisture, the residual time of the water content in the hydrogel is lower than that promoted by the sellers and distributors of the commercial product.
