Abstract
     This study was carried out in the green house of the Agricultural-Research and Experiment>Station, College of Agriculture, University of Kirkuk, Sayada area, Kirkuk, Iraq during the season 2021-2022 to study the effect of humic and potassium sulfate spraying on the growth and yield of Rubegym strawberries. The experiment was-included two factors, the first being three levels of sulfate Potassium (0, 1000 and 20000) mg L-1, and the second factor was three concentrations of humic, which is (0, 2 and 4) g L-1, using the randomized complete block design (R.C.B.D.) as a factorial experiment, using 10 seedlings per experimental unit, and the data were analyzed statistically using the (SAS V 9.0) program, and the averages were compared according to Dunkin's multinomial test at the probability level (0.05). Total. Soluble. Solids and vitamin C compared to control treatment.
