Abstract

A field experiment was carried out during winter seasons of 2021-2022 and 2022-2023 at the Experimental Farm of Ornamental and Medicinal Plants, Faculty of Environmental Agriculture Science at El-Arish, Arish University, North Sinai, to study the effect of three types of organic fertilizers, i.e., chicken manure (ChM), vermicompost (VC), compost (C) and there mixture as well as three sowing dates were as October 15 ^th, November 1^st and November 15 ^th for both seasons on growth, seeds, roots and mucilage yields of Althea rosea plant. The result showed that the highest values of all growth parameters: plant height, number of leaves and fresh and dry weight of leaves recorded at the first sowing date October 15^thwith chicken manure fertilization at (5 t/fed) plus of vermicompost (3 t/fed). In addition, the highest increase in root length, fresh and dry weight of root, yield of root and seeds, percentage and yield of mucilage in root and seeds achieved in early sowing date mid-October and mix of vermicompost and chicken manure.
