إضافة وسم | الملخص: | Cocoa (Theobroma cacao L.) comes from the Greek Theobroma, which means food of the gods, and cacao, from the Aztec. In our country, cocoa is one of the main traditional export products. It is currently considered at international level for being the country that has commercialized more than 60% of the cocoa processing, such as the fine aroma cocoa. The research work was carried out in the La Reveza sector, Ventanas canton, province of Los Ríos. The objectives were: i) To identify the appropriate frequency of application of calcium polysulfide to reduce the incidence of moniliasis and its production. ii) To evaluate which of the levels of calcium polysulfide had the lowest incidence of moniliasis. iii) To determine which of the treatments had the lowest percentage of moniliasis incidence and the highest production. The methodology applied was a completely randomized block design (CRAB) in a 3x3x3 factorial arrangement. There were 9 treatments: T1 (15 days + 2 liters); T2 (15 days + 3 liters); T3 (15 days + 4 liters); T4 (21 days + 2 liters); T5 (21 days + 3 liters); T6 (21 days + 4 liters); T7 (30 days + 2 liters); T8 (30 days + 3 liters) and T9 (30 days + 4 liters). The comparison of frequencies and levels of calcium polysulfide on the incidence of monilasis and production in cocoa clone CCN-51 was evaluated. An analysis of variance, Tukey's test at 5% was carried out to compare the averages between factors and their interaction. Correlation analysis and simple and multiple regression at 5%. According to the results, variability of the treatments was evidenced, which confirms the interaction of their genotype with the environment. The treatment that outperformed in weight in both fresh and dry kernels was T9 (30 days + 4 liters) with 387.87 g and 114.90 g, respectively. |
