This study aimed at investigating the effect of ammonium sulfate (20.6% N) at
300 Kg/fed, calcium superphosphate (16.5% P205) at 200 Kg/fed, plant nutrients
(Nofatrein) as foliar spray and bio-fertilization (Microbein) on growth and chemical
composition of Euryops pectinatus (L.) Cass. The treatments were 100% NP (AS
CONTROL), 75% NP, Microbein alone, Microbein+ 75% or 50% of soil application,
Nofatrein alone, Nofatrein + 75% or 50% of soil application, Microbein+ Nofatrein and
Microbein+Nofatrein+50°/o of soil application. All the treatments received constant
dose of potassium sulfate (48% K20) at 150 Kg/fed (recommended) but the plants
received different percentages of the full NP rate (NP 100%) . The field experiments
were carried Out during the two successive seasons of 2004/2005 and 2005/2006 at
the Experimental Nursery of the Ornamental Horticulture Department, Faculty of
Agriculture, Cairo University. There was a significant increase in plant height by using
the combination of bio-fertilizer and 75% of the chemical soil application. Also,
combining Microbein with 50% of the soil chemical fertilizers and Nofatrein
significantly increased plant height and stem diameter. Applying the foliar fertilizer
Nofatrein caused the maximum number of branches per plant and stem diameter in
both seasons. There were three treatments (viz. Nofatrein alone. the treatment of 75%
chemical fertilization combined with Microbein, and the combination of 50% chemical
fertilization + Microbein + Nofatrein) that gave the best result in terms of plant fresh
and dry weights, with insignificant differences between them. The highest number of
flowers per plant, root fresh and dry weights and total chlorophyll content were
obtained from plants supplied with 50% chemical soil fertilization, combined with
Microbein and Nofatrein.
