In order to investigate the effect of different amounts of chemical fertilizers (urea) and organic (sugar cane filter) on wheat yield, an experiment was conducted in 2014 as split plots in a randomized complete blocks design with three replications in the land cultivation plant of Haft Tape sugar cane (Shush) was implemented. Sugar cane filter fertilizer was used in four levels (without filter cake (T1), 20 t / ha (T2), 40 t / ha (T3) and 60 t / ha (T4) as the main factor and Fertilizer urea was considered as a sub factor in there levels of fertilizer: No-fertilizer (N1), 100 kg/ha (N2) and 200 kg / ha (N3). The results of analysis of variance of treatments showed that the effect of sugar cane filter at 5% probability level and fertilizer urea at 1% probability level was significant for all studied traits except for 1000 seed weight. Also, interaction of treatments on yield and yield components of wheat was not significant. The results of the comparison of the mean of the data showed that the increase of sugar cane filter as a organic matter to soil, plant height, spike length, spikelet number per spike, number of seeds per spike, number of spikes per square meter, 1000 grain weight, grain yield per square meter and harvest index significantly increased. The treatment of 60 tons of filter cake per hectare increased seed yield by about 137. 6 gr/m2 (from 648.4 to 510.5 gr/m2), equivalent to 21.2% of the control (without filter cake). Using Urea fertilizer, the measured traits significantly increased compared to the control. The application of urea fertilizer at 200 and 100 kg/ha increased grain yields of 228.5 and 201.3 gr/m², equaling 33.6% and 32.6%, respectively. In general, the results showed that increasing the use of urea and organic fertilizers has led to a significant increase in growth and functional attributes, and the best treatment for chemical fertilizers and organic fertilizers is 200 kg/ha and 60 T/ha of filter cake, respectively.
