Abstract This study was carried out at vegetables field of Horticulture and landscape department, College of Agriculture and Forestry, Mosul University, Iraq., during growth season 2018-2019 in order to study the effect of Humic acid addition to the soil in concentrations 2, 4g.l -1 and spray the organic extract Fylloton in concentrations 3, 6 ml.l -1 and Agroleaf power mineral fertilizer workshops in concentrations of 5, 10 g.l -1 and comparative treatment (no additives) on growth and yield of Cabbage hybrid plants (V. Blue Jays). The three fertilizers were added in three stages 15, 45 and 75 days after seedling. The study included seven treatments carried out in the field according to the Randomized Complete Block Design R.C.B.D. with three replicates. The results can be summarized as follows: The spraying process was performed by Fylloton fertilizer at a concentration at 3 gm.l -1 resulted in significant superiority on the comparative treatment in the character of early maturity by 12 days in addition to significant superiority compared to other fertilizer treatments. In comparison, the length, diameter and cohesion head characters were significantly superior with comparative treatment where reached (16.00 cm, 15.63 cm and 1.220) respectively. The same treatment and concentration above also achieved a significant superiority in yield characteristics (average weight of marketable head 1688.67g, early marketing yield 35.400 ton.hec -1 , total marketing yield 46.43 ton.hec -1 , total yield 67.21 ton.hec -1 ) Which significantly outperformed all other treatments. The treatment of ground addition of humic acid at a concentration of 4 g.L -1 gave a significant superiority compared to the comparative treatment in the characteristics of height of the plant amounted to 22.23 cm and early maturity by 7 days and early marketing yield 22.278 ton.hec -1 and total marketing yield is 36.02 ton.hec -1 and total yield is 53.72 ton.hec -1 . Also, the treatment of foliar spraying with mineral fertilizer with a concentration of 5 g.l -1 gave a significant superiority over the comparison treatment in the yield characteristics (1326.33(g), 26.942 ton.hec -1 , 36.47 ton.hec -1 , 53.90 ton.hec -1 ) respectively. It is clear from all the results that all fertilizers used exceeded the comparative treatment in most of the studied traits and treatment Fylloton concentration of 3g. L -1 showed a significant superiority over all other treatments and for most studied traits. Key words: Cabbage, Humic acid, Fylloton, Agroleaf power. Introduction Many important winter vegetable crops are grown in Iraq , Some of these crops belong to the Cruciferae family, including the cabbage crop Brassica Olearacea var. Capitata is widespread . As is known, the part eaten is the head, which mainly contains leaves wrapped around each other which are consumed fresh or in the work of pickles (Matlub, 1989) Because it contains many nutrients including 3-5.4% carbohydrates, 1-2% proteins, 0.2% fats and mineral elements such as calcium, phosphorus, potassium, magnesium, iron, vitamins such as vitamin A, C and thiamine, Cabbage has medical benefits such as stomach ulcers, lowering blood sugar and protecting against cancer (Euras et al., 2011; Tatlay and Fahey, 2011). Cabbage is grown in many countries of the world and the China, India, Russia, Japan and South Korea rank first in production (FAO, 2016), the cultivated area in Iraq is estimated according to the latest statistics for this crop 1500 hectares in 2014 with an average productivity of 12.667 ton.hec -1 (Arab Organization for Agricultural Plant Archives Vol. 20 Supplement 1, 2020 pp. 2543-2549 e-ISSN:2581-6063 (online), ISSN:0972-5210 *Author for correspondence : E-mail : abdullah.aldabbagh2017@gmail.com Development, 2014) when comparing the productivity
