Resumo

This study aimed to evaluate the effect of different irrigation depths on the levels of photosynthetic pigments in seedlings of TSH 1188 genotype cocoa and indicate the best irrigation depth for seedling production based on these characteristics. For this purpose, five irrigation depths were applied, corresponding to 4, 6, 8, 10 and 12 mm day-1. The experimental design was completely randomized with 20 seedlings per treatment. At 55 days after sowing, photosynthetic pigments were extracted and quantified, and the content of chlorophyll a, chlorophyll b, total chlorophyll and carotenoids was determined. The results were submitted to analysis of variance by the F test at 5% probability. Regression models that best applied to the effects of the irrigation depth on the evaluated characteristics were adjusted. The irrigation depth of 7.74 mm d-1 had the highest total chlorophyll content, being the most recommended for the production of TSH 1188 cocoa seedlings.
