Efecto del injerto en la producción de tomate riñon (Solanum lycopersicum)

Abstract

The aim of this research is to evaluate the effect of grafting plants of the Toivo variety on a Monarca F1 rootstock for the cultivation of tomatoes under greenhouses at the Education and training of peasant Center of Azuay (CECCA by its Spanish acronym) located in the Guachapala canton, in a tomato greenhouse, in which three treaments were used: the first, T1 with the Toivo variety with a spacing between plants of 20 cm, the second treatament T2,with a spacing of 40 cm, and the third T3, with the Toivo variety on a Monarca F1 rootstock with spacing of 40 cm. A randomized complete block design with three treatments and four replications was used in which the agronomic characteristics of the plants were measured, such as height, the number of clusters, fruit size, and production of the grafted plants compared to ungrafted plants,under the same conditions of fertilizer, irrigation, and fertilization. In addition. The incidence of nematodes was evaluated by laboratory analysis to check the resistance of the roots of each treatment. Among the main results obtained, it was found that the grafted Toivo variety obtained the best agronomic characteristics compared to the ungrafted varieties. However, it was evident that the grafted species was more prone to high nematode populations. Keywords: Grafting, tomato, nematode, crop, greenhouse.
