The effect of different liquid fertilizers on yield and quality in bread wheat

This research was carried out in Tekirdağ Namık Kemal University, Agricultural Faculty, Field Crops Department, Application and Experiment Fields in a randomized splitplot design with 3 replicates during the 2017-2018 wheat growing season. The aim of the study was to determine the effects of five different liquid fertilizers (Megafol, Sinergon 2000, Isabion, Amino 16 and KNO3) applied in two times as tillering (Zadoks 22. stage) and stem elongation (Zadoks 32. stage) on grain yield, yield components and grain quality of five bread wheat cultivars (NKU Lider, NKU Ergene, Nota, Rumeli, Aslı). As a result of the study, although there is no statistically significant difference between the liquid fertilizers, it was noticed that the liquid fertilizer applications generally significantly increased the grain yield, thousand grain weight and test weight compared to the control. In the experiment, the highest grain yield was obtained from KNO3 applied plots with 647,8 kg/da. The liquid fertilizer applied plots had 71,3-54,2 kg/da more grain yield compared with the control. In the experiment, the highest thousand weights were obtained from Sinergon, Amino 16 and KNO3 liquid fertilizers with 37,1 g and the highest test weight was obtained from Megafol and Amino 16 liquid fertilizers with 76,7 kg. The effect of liquid fertilizer applications on yield components such as plant height, spike length, number of grain per spike, and grain quality traits such as gluten index, sedimentation value and protein ratio were not statistically significant.
