Abstract

A research was conducted at Debre Markos, North West Ethiopia in 2015. The objective of the study was to evaluate different rate of nitrogen fertilizer on growth and yield of cabbage. The experment was laidout in randomized complete block design with four treatments and three replication. Nitrogen fertilizer have no significant effect on plant height and number of outer leaves, while leaf length, leaf width, head diameter, head fresh weight and head dry weight had significant effect on cabbage. The widest leaf width (21.86 cm) was recorded from 150 kg/ ha and followed by 100 kg/ ha, while the narrowest leaf width (16.93 cm) was from 0 kg/ ha N. The highest leaf length (20.1 cm) obtained was from 150 kg/ ha and the lowest leaf length (16.166 cm) was obtained from 0 kg/ ha. The highest head diameter (11.043 cm) was obtained from 150 kg/ ha, while the lowest head diameter was 8.696 cm noticed from 0 kg/ha. The highest fresh weight (0.771 kg/plant) was recorded from 150 kg/ ha and the lowest (0.442 kg/plant) was from 0 kg/ ha. The highest dry weight (0.114 kg/plant) was recorded from 150 kg/ ha while the lowest (0.0437 kg/plant) dry weight was obtained from 0 kg/ha of Nitrogen. Key words: Cabbage, nitrogen, yield.
