Efecto del injerto y del bioestimulante Fartum？ sobre la producción y calidad en tomate cherry

vegetable production in the region de arica y parinacota, chile, has adopted new technologies in crop production, irrigation and hybrid varieties, to increase yield and improve the quality of its products, taking into account the soil and climate characteristics of the coastal valleys of this region. according to the last agricultural census, tomatoes are the most important vegetable in the regional economy, both in area cultivated and in yield and production period. currently there are a number of studies underway on the use of biostimulants to improve plant nutrition, salt tolerance water stress. the objective of this study was to evaluate the effect of a natural biostimulant based on marine algae (fartum？) on parameters of fertigation, production and quality of the cherry tomato var. bambino. two trials were performed, one with entire plants and the other with grafted plants (multifort rootstock). the results suggest that using fartum？ improves the yield of cherry tomato in entire plants, although there was no significant difference of its application on grafted plants. we conclude that there was a significant increase in yield when this biostimulant was applied to entire plants, similar to the yield of grafted plants, which suggests that the use of natural products based on marine algae has an effect on this cultivar similar to that of grafting under conditions of salinity.
