Peat moss is an important component of potting media for a variety of
ornamental plants. In recent years, environmental concerns and the cost of peat have
escalated. In addition, many laws have been proposed to recycle and make use of
the organic wastes of different crops. To achieve this, straw of broad bean and
composts of bagasse, broad bean and rice were used as substitules for peat moss in
this study. Consistent results, that kept the same trend over the two seasons of this study,
could be summarized in the following: Using the broad bean compost medium resulted significantly in producing
the tallest Peperomia plants, the highest leaf and branch number/plant, the neavrest
shoot dry weight, and the heaviest fresh roots. The longest roots of Syngonium
belonged also to plants grown on the broad bean compost. The highest values of
the K% content of the three plants were observed In plants grown in the broad bean
straw medium. The bagasse compost medium resulted significantly in the tallest
Scheff/era plants and the highest number of leaves/Scheff/era plant, the heaviest
fresh and dry roots of Scheff/era and Syngonium, the heaviest shoot fresh and dry
weights and the highest contents of total chlorophyll, N, P, and carbohydrate of the
three plants Peperomia, Scheff/era and Syngonium. The peat moss medium
resulted In the longest Peperomie roots, while the rice compost medium produced
the longest Syngonium plants. It is recommended to use the straw or compost of many crops such as broad
bean, sugar cane (baqasse) and rice as cheap natural media instead cf the
expensive imported peat moss.
