Two field experiments were carried out during two successive seasons of 2002 and 2003 at the Experimental Farm of the Faculty of Environmental Agriculture Science, El-Arish, Suez Canal University to study the effect of irrigation water quantity and different rates of complete fertilizer on the growth rate, flowering characters and plant nutritional for Tagetes erecta L., Zinnia elegans J. and Gomphrena globosa L. plants. The obtained results showed in most cases that application of irrigation water at level of (800 m³/fed.) being the most effective and favorable treatment on increasing plant growth rate and flowering characters per plant and unit area. That was followed by irrigation water with (600 m³/fed.) while, application of the lowest level of irrigation water (400 m³/fed.) being recorded the minimum values. On the other hand, application of complete fertilizer (Sangeral) at the rates of 0.5, 1.0 and 1.5% through irrigation water (fertigation methods) recorded the maximum values of plant growth rate and flowering characters but without significant differences between them in most cases. Whereas, application ofcomplete fertilizer (0.1%) being the superior treatment regardffig total carbohydrates and plant nutritional status (N, P and K content), while the lost rate (0.5%) showed the minimum values in this respect. The interaction between the two factors of study in general, reflect significant effect on most studied parameters except few characters which were fluctuated in the two seasons.
