Selenium effect on wheat grain yield and quality applied in different growth stages

Small field plot experiments were carried out at the testing station of Central Control and Testing Institute in Agriculture VeÄžkĂ˝ Meder (Slovakia) experimental years 2014/2015, 2015/2016 2016/2017. Selenium salts form sodium selenite selenate applied growth phases: end tillering (BBCH 29) flag leaf ligule collar visible 39). The effect 2016/2017 on yield wheat grain was not statistically significant within observed variants. achieved mean yields range from 10.06 ± 0.81 to 11.07 0.29 t/ha 9.82 0.54 10.32 0.10 t/hain 11.23 0.76 11.64 0.51 Selenate comparison with influenced selenium accumulation grains more positively. However, a difference recorded variants application phase phase. influence content macroelements P, K, Ca microelements Cu Fe only; its decreased element control variant. Statistically significantly higher values fiber fat after stage tillering.
