Response of roselle Hibiscus sabdariffa L." plant to some growth conditions
Hyam Abd El-Azim Abd El-Gawad;
Abstract
In pot experiment Karkade plants (Hibiscus ...•. ahdar!ffa L.
• cv. Dark Red) were fertilized with two nitrogen sources and with
1\.. at two levels either combined together or separately applied. The amount of each fertilizer was added at three doses: 10% at S\1\Vjng time, 4() 0-'il ilt thinning ancJ 50 Oftl at the time Of first noraJ
hud appearance.
The mean obtained results clearly indicated that the vegetative grmvth of Karkade plant highly affected with different applied treatments. Since the final measure of growth, i.e.the dry matter accumulation is significantly increased especially with low level of each treatment.
Also, effects of these nutrients were prolonged to the
reproductive growth and the final yield as well.
Finally, from the present study it could be concluded that nitrogen is essential nutrient for Karkade plant but mostly in low level when growth behaviour and the final economic yields were considered. Also, present study strongly admit the use of K in relatively medium or high rates-to some extent-when compared
with nitrogen element.
