That is why in this study the effect of three levels of shade on the cacao yield (Theobroma cacao L.) clone CCN51 was evaluated in Zamora Chinchipe province, "El Padmi" sector, using plants of approximately two years old. , with a planting framework of 3.5 m and 4 m, where a completely randomized design (DCA) was established, with 3 treatments corresponding to the three shade levels T1:0 %, T2:35 %, T3:80 % with 6 repetitions each, the experimental it consisted of a tree, with a total of 18 experimental units. The vegetative variables of the productive phase and its performance were; stem diameter, trunk cross-sectional area (ASTT), crown diameter, leaf area index, stomatal density, chlorophyll concentration, fruit length and width, fruit weight, number of seeds per fruit, number of ears per tree, yield and bromatological analysis (moisture, ash, fat, protein, brix and acidity). The effect of the treatments on the dependent variables was evaluated by ANOVA and test of means (Tukey) (p> 0.05). The results showed significant differences in crown diameter at the beginning of the application of the treatments, being T1 the smallest and T3 the largest with 160.8 cm and at the end of the test there were no significant differences, in the sami way in the concentration of chlorophyll the T3 presented a chlorophyll greater than 63.62, as opposed to 0% that showed a concentration of 44.34.There are no significant differences for the variables of stem diameter, trunk cross-sectional area (ASTT), leaf area index, stomatal density, chlorophyll concentration, fruit length and width, fruit weight, number of seeds, number of ears per tree and yield. Regarding the fat content, an exploratory assessment was made in which T1 presented 23.61, T2: 28, 19 and T3 obtained 31.31 %, unlike the rest. In general, no significant differences were found in the shadow factor for the different variables studied. Keywords: Theobroma cacao L, shade levels, yield. |
