【 摘 要 】

The use of nitrogen phosphorous fertilizers and untreated sewage from urban areas by crops is an agronomic, economic and environmental necessity. The aim of this study was to evaluate the response of growing wheat to the application of different nitrogen fertilizers, irrigated with wastewater and well water. Haplic Vertisol soil was used. Was used as indicator crop wheat variety Tlaxcala F2000. Fertilizers applied were: commercial fertilizer (CF) consisting of monoammonium phosphate + urea, organic fertilizer (FO) Vermicomposta, and slow release fertilizer (FL) combination of: urea, H2PO4 and clay. The mixture contains N and P, 8.08 and 6.3 wt%, respectively. The treatments were designed to test the effect of each single one of these materials and the combination FL + FO. The fertilization of N and P was (280-80-0). With the laboratory analysis data of N and P of the plants, the recovery efficiency of these nutrients was calculated. Dates of Sampling Water and Fertilizer water interactions were significant at (p < 0.05) for fresh and dry biomass in the experimental cultivation also increased the number of grains by irrigating with wastewater.
