Type: article
Abstract: The field experiment was conducted at two locations, Qlyasan and Kanipanka in Sulaimani governorate, Iraq.The main aim of this research is, to evaluate the impact of adding various levels of Humic Acid and Sulfur rates on maize yield and yield components.Experimental treatments have been organized and a factorial experiment was laid out in a complete randomized block design with three replicates.The treatments included four levels of humic acid, and four levels of sulfur incorporated into the soil.The results showed that the effect was significant at (P < 0.05) on the reproductive growth criteria of a maize plant.The number of kernels per ear, the weight of 100 kernels (g), kernel yield (ton ha -1 ), biological yield (ton ha -1 ), harvest index and relative yield maize plant from both of locations.While the results showed that the humic acid and sulfur application significantly affected of the number of kernels per raw from Kanipanka and of the ear diameter (cm) from Qlyasan, it did not affect the number of kernels per raw from Qlyasan location and by the ear diameter (cm) from Kanipanka location.
