| Abstract | To examine the effects of nitrogen and reclaimed municipal wastewater irrigation on yield of greenhouse tomato and nitrogen economy, field experiments were carried out. Root-layer mineral nitrogen, total nitrogen, abundance of soil microorganisms, tomato yield, nitrogen in fruit, partial factor productivity from applied N, apparent N loss and nitrogen supplying capacity were analyzed. The results indicated that RMW irrigation leaded to an average of 1.72 - 40.39% increase in mineral nitrogen and total nitrogen of rhizosphere soil in 1st, 2nd and 4th cluster fruit expanding stage. RMW irrigation significantly increased the microbial population of rhizosphere soil in the crop growth stage, yield of tomato, nitrogen in fruit, partial factor productivity from applied N and nitrogen supplying capacity. RMW irrigation reduced the amount of topdressed nitrogen and promoted rhizosphere nitrogen supplying capacity and this prevent disposal of RMW to the river and minimize groundwater exploitation. |
