Effect of active dry yeast and chemical fertilization on vegetative growth and the main constituents of euonymus japonicus thunb plant

الملخص EN

This work was carried out in a plastic house during the two successive seasons of 2002 / 2003 and 2003 / 2004 at the nursery of Ornamental Plants Research Department, Horticulture Research Institute, Agricultural Research Center, Giza, Egypt, to study the influence of active dry yeast (4 g/l), two chemical fertilization levels (6 and 12 g/plant), alone or in combination, on vegetative growth and chemical constituents of Euonymus japonicus plant.

The obtained results showed that using yeast twice plus 6 g NPK/plant increased plant height, fresh and dry weights of shoots as well as nitrogen percentage in roots.

Applying yeast twice alone led to an increment in number of branches, fresh and dry weights of roots, carotenoids content in leaves and potassium percentage in roots.

While, supplying the plants with yeast thrice caused an increment in stem diameter, root length and nitrogen percentage in shoots.

It can be concluded that using active dry yeast twice alone or with 6 g NPK/plant enhanced the growth of Euonymus japonicus plants.

From economical and environmental point of view, it can be recommended to use active dry yeast twice alone.
