A factorial experiment was carried out during the year 2021 in one of the villages in the Abu Ghraib district – Baghdad, to evaluate the effect of adding animal waste and dry bread yeast suspension on some vegetative growth characteristics of cucumber plants (Hadeel hybrid) grown under a protected environment. Three types of animal wastes (cattle, sheep and poultry) and dry bread yeast suspension were selected and the control treatment without adding any organic waste. The results indicated that poultry manure showed the best effects in the studied traits, which included leaf area ) of 31.69 cm2 (, dry weight of shoot )40.0 g(, number of leaves )32.73 leaf plant-1 ), stem diameter (11.48 mm), plant length (224.3 cm) and number of nodes 33.73 node plant-1 ).On the other hand, adding dry yeast suspension to plants improved in all studies of vegetative growth characteristics compared to the control treatment.
