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.
