The study focused on yield, water utilization, nutrient reaction and the amount of yield per kg fertilizer of corn hybrid NX 47279 in 2011 and 2012. Based on the yield results it can be concluded that the largest yield in 2011 was 15 963 kg ha-1 at level N120+PK, while in 2012, the maximum yield amounted to 14 972 kg ha-1 at level N90+PK. Surplus yield per kg fertilizer proved that in 2011 level N30+PK resulted in the highest surplus yield (42.3 kg kg-1) compared to the control treatment. In 2012, yield growth was 18.0 kg kg-1 compared to the control treatment. We measured at level N60+PK 17,5 kg kg-1 compared to at level N30+PK, at the N90+PK 17,7 kg kg-1 compared to at level N60+PK. level N30+PK kg kg-1, 17.5 kg kg-1 at level N60+PK and 17.7 kg kg-1 at level N90+PK compared to the control treatment.
In our study the nutrition reaction of four varieties of winter wheat (KG Bendegúz, KG Kunhalom, KG Kunkapitány, KG Széphalom) has been investigated. In the experiment the effect of twenty different nutrition doses on the yield and thousand kernel weight of the wheat varieties has been studied. Significant difference could be figured out amo...ng the yield and thousand kernel weight of the wheat varieties, so the choice of the proper variety determines the quantity of yield. KG Kunkapitány had the highest yield, while KG Széphalom had the highest thousand kernel weight in the experiments.
Investigating the effect of the nutrients on the yield the conclusion was that all nitrogen doses had significant yield increasing effect compared to the untreated plots, but among the 40, 80 and 120 kg ha-1 doses there was no statistical difference. In the case of phosphorus the 40 kg ha-1 dose showed statistically verifiable increase of the yield, while potassium doses have no influence on the yields. The thousand kernel weights reached the maximum values where the highest nutrient doses were applied.
