EFFECT OF NITROGEN FERTILIZATION ON THE GROWTH AND YIELD OF HIBISCUS SABDARIFFA L.

E. S. A. El Gamal, Farouk A. Omar, M. M. Mahmoud
The growth and yield of roselle / Hibiscus sabdariffa L./ was increased by application of nitrogen fertilizer. The yield of dried sepals was highly correlated with rate of fertilizer application up to 100 kg N per feddan. Nitrogen fertilizer supplied as ammonium sulphate gave significantly higher yields than when it was supplied as calcium nitrate or urea. Highest yields were obtained when the fertilizer was applied in two dressings - at thinning /one month from sowing/, and during rapid vegetative growth /2.5 months from sowing/.
