ABSTRACT. This experiment was conducted at the Agricultural Research
Station of King Abdulaziz University at Hada Al- Sham Center
in Makkah Al-Mokarramah Region, during two seasons (1997 and
1998) using two varieties of cabbage (Copenhagen V1 and Brunswick
V2). The experiment aimed to study the effects of four nitrogen levels
(0, 100, 200, and 300 Kg N/ ha) on the yield of the tested cabbage varieties,
the nitrogen content of different plant parts and the nitrogen
uptake ( kg N ha—1 ).
Results revealed that the season has no effect on cabbage
growth except on nitrogen content in the stem at 5% signficance
level. The difference of variety has a significant effect on fresh
and dry weights of the leaves, stems, roots, and the whole plant.
However, Brunswick (V2) was superior compared with Copenhagen
(V1). Addition of 200 KgN/ ha was adequate for increasing
fresh and dry weights of heads, leaves, roots, and whole
plant. Fertilizing cabbage plant with 100 Kg N/ ha was adequate
for increasing the nitrogen content in the heads, leaves, stems and
roots. The second variety Brunswick (V2) was superior in total nitrogen
uptake compared to Copenhagen (V1). Addition of 100 Kg
N/ ha resulted in significat increase in nitrogen uptake by plant. |
