Abstract: The paper aims to improve water and fertilizer use efficiency, and then reasonably reduce nitrogen application. The effects of different combination of water and fertilizer on tomato quality and yield were studied in this paper. The results showed that: the irrigation method of drip irrigation 2 h every 5 days could improve the brightness of tomato, the soluble sugar content of tomato could be improved effectively when the soil moisture content was confirmed to be 70%-90% of the field capacity. The moderate irrigation method (when the irrigation quota was 3771.98 m3/hm2) produced more tomato number, increased the ripe tomato ratio and deferred the main production period, then improved the initial production and total production of tomato. Both nitrogen application levels and the interaction effect of water and fertilizer were no significant effect on quality and yield of tomato(P>0.05). The effect of water on the tomato quality and yield was greater than that of nitrogen fertilizer.
