Abstract

This study was conducted to determine the effect of different irrigation intervals
and different nitrogen fertilizer rates on cabbage yield and cabbage N uptake. Three
irrigation intervals and four N rates were used for two seasons (1988/1999-
199912000). The three irrigation treatments used were (2, 4, and 7 days) with the total
amount of water applied at each treatment being fixed at the rate (3733 m³ 1 season),
and the four N rates used were (0,100, 200, and 300 Kg N/ha).
The results showed no significant differences in cabbage yield and N uptake by
plants between the two seasons, while there were significant differences in yiled and
N uptake between the different irrigation interevals, as yield and N uptake were
reduced with the inctease in watering intervals from 2 to 7 days. Furthermore, N
fertilization has significant effects on yield. Yield and N uptake were increased
significantly as N rate increased from 0 to 200 Kg N/ha, However, yield and N uptake
were decreased as N rate of 300 Kg N/ha was used. Thus, 200 Kg N/ha is the
optimum rate for cabbage. It was found that the yield and N uptake increase witt the
incease in N fertilization rate and reduction in watering intervals.
