Abstract
Abstract The experiment was carried out in the vegetable field of Horticulture and Landscape Department / College of Agriculture and Forestry / University of Mosul, during 2021-2022 season to investigate the effect of administration of bio char in three doses (0, 3.5, 7, 10.5 t. Ha -1 ) and three Concentrations of Amino acid(Steam)(0, 10, 15 ml.L -1 )on growth and green yield of onion variety (Karbala) The experiment was designed according to randomized complete block design (RCBD) with three replications. The results showed that : Adding the bio char in doses of 7 t. Ha -1 to the soil significantly increased several growth and yield properties(bulbs number, leaves number, bulb diameter, fresh and dry weight of leaves and roots, plant yield, and biological yield). Spraying amino acid (Steam) at 15 ml.L -1 doses gave the highest values of plant height, fresh and dry weight of leaves and roots per plant, diameter of bulb neck. But highest values of average weight of bulb and biological yield was from spraying amino acid (Steam) at 10 ml.L -1 doses. The combination treatments between bio char and amino acid (Steam) show a significant effect in some vegetative growth and yield parameters of onion.
