USE OF URBAN SEWAGE AS COMPOST FOR WHEAT CROPMohammadreza Yavarzadeh, Hilda Shamsadini and Shila Shamsadini
A field experiment was factorial in the form of completely randomized blocks, with 4 replications. N.P.K was considered as factor A, in four levels (recommended value,30% more than recommended value,30% less than recommended value and control) and compost was as factor B, in four levels (control,15t/ha 20t/ha and 25t/ha).The results showed that the effect of N.P.K on all studied traits was meaningful. Also, the effect of compost on all cultural traits became meaningful. The highest seed yield was observed from N140P70K60 treatments, with 5603 kilograms per hectare. The results indicated that as the fertilizer increased from N140P70K60 to N180P90K80, the yield rate decreased to 3.8 percents.
