Conference Paper Description

The study was conducted in the fields of the Department of Horticulture and Landscaping/College of Agriculture/University of Al-Qadisiyah/Al-Nouriah district-for the 2019-2020 agricultural season to study the effect of spraying with organic sulfur and hydrogen peroxide on the growth and yield of onions, Allium cepa L, where the study included two factors: The first factor was spraying organic sulfur at concentration (0, 2)., 4 ml. L-1) and symbol S1, S2, S3 and the second factor spraying with hydrogen peroxide at a concentration (0, 2, 4 ml. L-1) and symbolized by B1, B2, B3 and the interaction between them. A factorial experiment was conducted according to the randomized complete block design (RCBD) with three replications and the comparison between the treatments was done using the least significant difference test L.S.D at the probability level of 0.05. The results showed that spraying with organic sulfur or spraying with hydrogen peroxide in a single form led to a significant increase in all studied traits, as well as the interaction between the two factors, where the treatment S3B3 recorded the highest significant increase in plant height, leaf length, number of leaves, leaf neck diameter and yield weight per hectare of 82.00 cm plant.-1, 63.0 cm, 11.00 leaf. Plant-1, 55.67 mm. Onion-1, 22.67 mm. Onion-1, 4.146 tons. hectare-1, respectively.
