Abstract: The effect of different levels N application (225,450,675 and 900 kg/ ha) on cucumber growth and N03-N changes in fruit and soil was studied in sunlight greenhouse with cucumber. The result showed that high nitrogen fertil-izer improved the growth and yield of cucumber,but the yield decreased at 675 kg/ ha;Correlation between N levels andN03-N in soil and cucumber was significant positive,N03 - -N in soil became lower with the cucumber growing develop-ing and then increased after fruiting stage in the whole growth stage,while N03-N in fruit increased and then becamelower.

Key words: Nitrogen levels, Cucumber, Soil, Nitrate
