Response of growth, yield and quality indicators of tow cultivars of Kohlrabi (Brassica oleracea var gongylodes) to the addition of the

Abstract
A field experiment was conducted in the field of the Horticulture and Landscaping Department /College of Agriculture/ University of Karbala in Al-Hussainiya District of Karbala Governorate during the autumn season 2021-2022 to study the response of growth and yield indicators of the word plant to the effect of two factors. Bread at concentrations of 2, 4, and 6 gm L-1 resulted in eight treatments with comparison treatment, and the second factor was classified and included two types of words, White Vienna (W) and Purple delicacy (P). The experiment was designed according to the (split plot system) Within the (Randomized Complete Block Design) and with three replications, as the class represents the main plots, the addition of Biohealth treatments, and the spraying of baking yeast suspension, the secondary plots. The experiment included 48 experimental units, and the differences were compared using the Least Significant Difference test (L.S.D) at a probability level of 0.05, and the results were summarized as follows:
The T8 treatment was significantly superior to the rest of the treatments in the percentage of potassium in the leaves 1.351%, the average leaf area amounted to 31.26 dm2, the swelling stem size 275.7, and the percentage of dry matter in the swelling stem 16.60%. The results also show that the two treatments T8 and T7 did not differ significantly between them and outperformed the rest of the treatments in the percentage of nitrogen in the leaves, the percentage of phosphorus in the leaves, the weight of the swelling stem and the productivity of the plant And the percentage of nitrogen in the swelling stem and the percentage of phosphorus in the swelling stem, as the results show that the fertilizer treatments T8, T7 and T6 were significantly superior to the rest of the treatments in plant height, chlorophyll concentration in the leaves, percentage of total dissolved solids (T.S.S), percentage of carbohydrates in the swelling stem and the percentage of protein in the swelling stem. It is also noted from the results that the transactions T8, T7, T6 and T5 are superior in the number of papers As for the percentage of potassium in the swelling stem, T8, T7, T6, and T2 treatments were superior, and all fertilizer treatments were superior to the comparison treatment in the dry percentage in the leaves, as well as in the percentage of fibers in the swelling stem (except T3).
As for the varieties, the P variety was superior to the W variety in the percentage of potassium in the leaves 1.305%, the number of leaves 19.24 leaf, the percentage of dry matter in the leaves 15.82%, the volume of the swelling stem 248.1 cm3, the percentage of dry matter in the swelling stem 15.60%, and the percentage The nitrogen in the swelling stem was 1.090% and the percentage of protein 1.080% The results showed that there were no significant differences between the two cultivars in the chlorophyll content of the leaves, the percentage of nitrogen in the leaves, the percentage of phosphorus in the leaves, the plant height, the rate of the swelling stem weight, the plant productivity, the percentage of total soluble solids, the percentage of phosphorus in the swelling stem, the percentage of potassium in the swelling stem, and the percentage The percentage of carbohydrates in the swelling leg and the percentage of fiber in the leg.
The treatment of overlapping P of cultivar T8 excelled in most traits and gave the highest leaf area of ​​40.21 dm2 , the highest plant productivity 9.411 ton ha-1 and the highest concentration of carbohydrates in the swelling stem 7.810 mg. GM-1 and the highest percentage of protein in the swelling stem was 1.534%.
