The application spray of some organic extracts considers a suitable nutrient supplement to the utilization of chemical fertilizers. So, it needs to more study led to obtain the great quantitative and qualitative characteristics of vegetative crops. An experimental study was conducted at the Central Laboratory of Agricultural Climate (CLAC), Agricultural Research Center, Dokki, Egypt. Celery plants were planted into a net house during the two successive winter seasons of 2018/2019 and 2019/2020. This studied the effect of foliar application of poultry manure tea, vermicompost tea, and algae extract on the vegetative growth, productivity, and quality of celery plants.The trial design was a randomized complete blocks design with three replications. Nine treatments of organic extracts as spray were applied using two concentrations (10, 20 ml/l) for (algae extract, poultry manure tea, and vermicompost tea) and with additional 5ml/l molasses for (poultry manure tea and vermicompost tea) compared with control (water spray). A mixture of poultry manure tea at 20 ml/l + 5ml/l molasses recorded the best parameters of vegetative growth, yield, chemical and quality characteristics followed by a mixture of vermicompost tea at 20 ml/l + 5ml/l molasses with no significant differences between them. Conversely, the least parameters of vegetative growth, yield, chemical, and quality characteristics were obtained by spraying water (control) in both seasons.
