Abstract
ABSTRACTThere is a strong need to substitute chemical fertilizers with bio-fertilizers and organic compounds. This study was done with the aim of improving the Pelargonium peltatum quantity and quality by a phosphate bio-fertilizer (Barvar 2). Bio-fertilizers and organic compounds enhance soil fertility and improve production in sustainable agriculture. Two levels of bio-fertilizer and different media along with a variety of organic compounds were used to evaluate their effects on some morphological and physiological features in P. peltatum. The results showed that all treatments significantly affected all studied traits except for internode length. The use of bio-fertilizer along with media containing a variety of organic materials, especially sand + tea waste compost + cocopeat (coconut fibrous husk) + pond sediment, also garden soil + sand + municipal solid waste compost + pond sediment, had a greater impact on these traits. The measured characteristics of the sand + tea waste compost + cocopeat + water spreading soil medium were in desirable and appropriate levels with the standard media used for ornamental plants.
