The effect of fertilization on the yield components of winter wheat

We investigated the effect of fertilization on the yield components of winter wheat in the crop-year 2016/2017. The experiment was set up in three replications on the area of the SZTE Tangazdaság Ltd. in Hódmezővásárhely. The soil was meadow soil. The forecrop was sunflower. Six fertilizer treatments were used besides the control: N80PK30, N100PK30, N130PK30, N150PK30, N170PK0 and N170PK50 kg/ha active ingredients. Experimental results were processed using single factor ANOVA. The number of spikes/m2 was 564.67 in the control treatment. In the N100PK30 and N130PK30 treatments we measured significantly higher values of 567.67 and 677.33 spikes/m2. The number of kernels per spike was 36.5 in the non-fertilized parcels. We reached the highest value of 43.77 kernels in the N130PK30 treatment. The difference was not significant. The thousand kernel weight changed slightly due to the fertilization. We measured 31.08 g in the control treatment. We got the maximum value of 32.71 g in the N130PK30 treatment. The difference was not statistically justified. Our scientific results showed, that the N130PK30 kg/ha fertilizer level was the optimum for the winter wheat in 2016/2017.
