A field experiment was carried out in one of the agricultural fields which belongs to the Khalis district in Diyala Governorate, Iraq, located at a distance of 16 km northeast of Baqubah, during the fall season of the year 2021-2022 in a soil with a clay texture. An experiment was carried out with the aim of studying the effect of organic fertilization with four levels of humic acid, namely 0, 2 g.M-2 and 4,6 g.M-2 and bio-fertilization with the Trichodermia harzianum fungus, which was added at a rate of 0.3 gm, affected some vegetative traits of Nigella Sativa L. The results showed that the treatment of adding humic acid at the level of 6 gm?² was significantly superior in terms of plant height, number of branches and dry vegetative weight, which amounted to 53.51. cm and 16.01 branches. plant-1 and 31.89 gr. plant-1, respectively, and the treatment of adding humic acid at the l..
