Optimization growth and yield of cabbage plant by foliar application of vitamin B12 and GSH

Abstract

This research was carried out at vegetable field of the College of Agricultural Engineering Sciences - University of Baghdad during fall season 2019. The experiment was conducted using factorial within Randomized Complete Block Design arrangement with two factors and three replicates (3X3). Spraying with vitamin B12 represented the first factor (0, 50, 100 mg.L-1), which symbolized (C0 , C1 , C2 ). GSH (0, 50, 100 mg.L-1), which symbolized (G0 , G1 , G2 ) represented the second factor. The research objectives are assessing the impact of the mentioned factors and their interaction on cabbage vegetative, quality, and yield traits. Results showed the effectiveness of two ways interaction treatment C2G2 in producing significant increases in plant height (38.03 cm) leaves number (15.33), Head hardness (26.83 kg.cm2 ) Head TSS (8.41%). However, C1G2 produced the heighest stem diameter (21.67 mm) Head periphery (57.17 cm) and total yield (21.64 ton.ha-1).
