Abstract
Application of N as ammonium nitrate (33.5%) at the rates of 0.4, 0.8, 1.6, 3.2
glplant with or without biofertilizer Nitrobein (Azotobacter + Azospirillum), were used
on Euphorbia pulcherrima, wil/d during 200212003 and 2003/2004 seasons at
Antoniades Research Branch, Hort. Res. Inst., A.R.C. Alexandria. Egypt.
Fertilizing E. pulcherrima with 1.6 g ammonium nitrate or 0.8 g ammonium
nitrate in presence of biofertilizer gave the highest values in the most of studied
characters (plant height, fresh and dry weight of stem and leaves, leaves area and
number of leaves per plant). Also, the highest content of total chlorophylls in the
leaves.
It can be concluded that, Nitrobein could decrease mineral N to 50% of the
suitable dose for the best growth and flowering of E. pulcherrima, with minimum
environmental pollution.
