Effect of Biohealth Biostimulant and Dry Yeast Suspension on some Chemical Characteristics of Leaves and the Total Yield of Two Varieties of Kohlrabi Brassica oleracea var Gongylodes

Abstract The purpose of this experiment was to determine the impact that applying biostimulant Boiohealth and spraying dry bread yeast suspension would have on chemical components leaves total yield two different varieties kohlrabi during autumn 2021-2022 at University Karbala’s College Agriculture. included factors, first factor includes eight fertilizer combinations, its without addition (T1), adding Biohealth (T2), a concentration 2 gm L -1 (T3), 4 (T4), 6 (T5), add + spray g (T6), (T7), (T8) second is words: White Vienna Purple delicacy. Treatment T8 outperformed rest treatments, as it gave highest percentage chlorophyll, which amounted 7.709%, nitrogen, 3.170%, phosphorous, 0.3659%, potassium, 1.351%, 27.00 tons ha . results show superiority variety over delicacy in chlorophyll 7.079% 0.3503%, respectively, while superior 2.864%, 1.305%, 22.76 Ton hectare
