Results of this study showed that foliar application with yeast increased significantly the vegetative growth and yield of cabbage, while Nitrogen fertilizer did not cause any significant effect, Meanwhile foliar spraying with active yeast suspension at rates of 3 and 6 g/L-1 recorded highest values of plant height, leaf length, leaf width, head diameter, head weight and yield /hectare, which reached (36.4,36.5 cm), (31.0, 32.3 cm), (29.7, 32.5 cm) (19.9, 21.0 cm), (1916.6, 2122.2 g), (82.1, 90.9 ton/hectare) respectively as compared with nonspraying 0 g/L-1, whereas the interfere between yeast suspension and Nitrogen fertilizer was significant, where yeast suspension at 6 g/L-1 and Nitrogen fertilizer at 3 g/L-1 recorded the highest rate in most of previous traits, also the spraying of yeast suspension and Nitrogen fertilizer at 3 and 6 g/L-1 has led to reducing in rate of maturity days, which reached (113.0, 116.0 days), (114.6, 114.4 days) respectively as compared with non-spraying 0 g/L-1. |
