Effect of Spraying with Organic Fertilizer and Sorbitol Sugar on Growth and Yield of Cabbage

This study was carried out at the field, Horticulture Dept. Field - College of Agriculture - University of Diyala – during the winter season (2021 - 2022) to study the effect of Spraying Organic Fertilizer and Sorbitol Sugar on the growth, yield produced from Cabbage (Glop Master). A factorial experiment with two factors, Organic Fertilizer concentration (0, 100, 150, 200 mL-1) and Sorbitol Sugar concentration (0, 5, 10 gL-1), was conducted according to randomized complete block design (R.C.B.D) with three replications. Results showed significant superiority of Organic Fertilizer at 200 mL-1 in the head height 24.62cm, steam diameter 2.408 mm-1, number of external leaves 8.774 leaf plant-1 , number of roll leaves 21.51 leaf plant-1 , dry weight 340.0 gL-1, the total chlorophyll content in leaves 59.57 unit spad, head weight 1.260 kg-1, head diameter 23.21mm-1, Production of one plant 1.578 kg-1 and total yield 52.61ton ha-1, then the lowest values in the control treatment). The result also showed significant increase of Sorbitol Sugar in concentration 10 g L -1 in head height 23.70 cm, steam diameter 2.336 mm-1, number of external leaves 8.931 , number of roll leaves 21.49 , dry weight 360.0 g-1, the total chlorophyll content in leaves 59.16 unit spad, head weight 1.290 kg-1, head diameter 23.08 mm-1, Production of one plant 1.581 kg-1 and total yield 52.72ton ha-1, then the lowest values in the control treatment ). The interaction between the two factors were significant for all the studied traits, Indicated that the response of Cabbage to first variable is related to the second one. Thus, the research has concluded that the Interaction of both variables; Organic fertilizer (200 m L-1) and Sorbitol Sugar 10 gL-1 has great combination to increasing the growth and the yield of Cabbage.
