Agregar Etiqueta | Sumario: | Tree tomato cultivation is highly desired both in our continent and throughout the world. The present work was based on the determination of the incidence and severity of paratrioza in the tree tomato crop and its relationship with the profitability of the crop, in the San Lorenzo parish, Bolívar province. The objectives set for this research were: i) Determine the phenological stages of the tree tomato crop in which there is greater involvement of paratrioza. ii) Evaluate the yield and quality of the fruits based on the incidence and severity of paratrioza. iii) Identify the damage caused by the incidence of paratriosis in the tree tomato crop. For the interpretation of results, descriptive statistics are used. Eight orchards were evaluated in different locations in the San Lorenzo parish. Among the main results, the following are presented: In the levels of incidence of paratrioza, the values oscillate between 8% (Loma Santa Cecilia) and 41 % (Amapolas 2), which suggests a fairly wide range of pest impact in the sectors studied. . . The Amapolas 1 and Amapolas 2 sectors have the highest incidence values, with 40% and 41%, respectively. For the severity of paratrioza, the pest reached 100%, this means that in all locations, the entire leaf surface of the tree tomato plants was covered by signs, spots and pustules of the disease transmitted by paratrioza. When evaluating the brix degree variable, it is shown that in general, the highest Brix degree values are observed in the samples from Loma Santa Cecilia 2 and Amapolas 1 with 12 and 12.2 °Brix. The weight of the fruits varies as Poppies 1 and Poppies 2 with 189 and 187 g respectively. In the yield by plots, sectors located at higher altitudes, such as Loma Santa Cecilia (with 1162.5 kg/plot) and Loma Santa Cecilia 2 (with 1550 kg/plot), have the highest values of yield per plot. |
