Abstract
Field trials were conducted in Egypt during two successive seasons 1996 and 1997, to assess the effect of active dry yeast and farm yard chicken and animal manure on the growth, fruiting and active substances of roselie plant (Hibiscus sabdariffa L.) The active dry yeast were applied as foliar spray with the three concentrations 0, 1 and 2 gm/L during different stages of growth. The data showed that the treatment with 2gm/L. with the vegetative, flowering and fruiting stage improving significantly growth, yield of calyxes and active substance. Chicken and animal manure which were treated at the level 14, 18, 25 and 27 m3 feddan enhanced the growth, quantity and quality of calyxes, particularly at the low rates.
