CASTRO, Nilmar Eduardo Arbex de et al. Planting time for maximization of yield of vinegar plant calyx (Hibiscus sabdariffa L.). Ciênc. agrotec. [online]. 2004, vol.28, n.3, pp.542-551. ISSN 1413-7054.  https://doi.org/10.1590/S1413-70542004000300009.

The objective of this work was to evaluate the yield of calyxes of Hibiscus sabdariffa L, a medicinal plant, at four planting times in Lavras - MG. The treatments were four planting times (October 18th, November 15th, December 18th 2001 and January 15th 2002) and a harvest was proceeded when practically there were no developing calyxes, almost at the end of the plant cycle. The numbers of calyxes per plant, the fresh and dry biomasses of calyxes and quality were taken into account. It follows that planting time influenced yield per plant and the fresh and dry biomasses of calyxes, differing from each other by Tukey test at 5%. In October planting, there was a higher yield (2,522kg/ha) with a yield 5.24 as high relative to the planting of the month of January (481 kg/ha). The planting s in the month of November to December showed yields of 1,695 and 1,093 kg/ha of dry calyxes, respectively and in relation to the same months of January, yield was of 3.52 to 2.27 times more. Harvest must be done as soon as the calyxes are ripe in order to preserve quality.
