Abstract
In order to study the effects of different levels of humic acid and phosphorus fertilizer on qualitative and quantitative characteristics of Rosell (Hibiscus sabdariffa), the exprimentwas conducted at research farm of University of Zabol, Iran in year 2012. The factors were phosphorus fertilizer (0, 100 and 200 kg/ha) and humic acid ( 0, 750, 1500 and 2250 g/ha). The expriment design was factorial expriment in base of randomized complete blocks design with twelve tratments and three replications. Resalts shown that the highest plant hight (144/22cm), number of fruit (87/56), 1000 seed weight (34/33g) were obtained at 2250 g/ha humic acid. Phoshporus fertilizer, also showed significant effects on plant hight, number of branch, number of fruit, total carbohydrates and anthocyanin maximum number of branch (11/75) and anthocyanin (0/000066 μmol.g-1) obtained in its second level. In this study, interaction of two factors on hight, number of branch, number of fruit and harvest index were significant. Maximum ecomomic yield (0/78 ton/ha) were obtained without incorporation with tird level of humic acid (1500g/ha).
