Yield of eight tomato (Solanum lycopersicum L.) cultivars in Granma province and their performance against Begomovirus
Main Article Content
Abstract
Two experiments were developed in the 2016-2017 and 2017-2019 seasons on a Fluvisol soil at the Agricultural Experimental Station, belonging to the "Jorge Dimitrov" Agricultural Research Institute, to determine the yield in eight tomato cultivars in Granma province and their behavior against begomovirus. These were planted in individual furrows 10 m long, in a randomized block design with three replications. The planting distance was 1.40x0.25 m per treatment. A factorial analysis of variance was applied for whitefly incidence and virus severity, and a two-way analysis of variance was applied for yield. Multiple comparison of means was performed by Tukey's test for P≤0.05. The results showed that both whitefly incidence and virus severity expressed low values, between 3.0 and 10.2 insects per plant in the former and between 1.02 and 1.31 % of plants affected in the latter. The cultivars showing the highest yields were HC-2580, HC-7880 and Rilia with values of 31.4, 31.0 and 29.6 t ha-1, respectively.
