In this study, the effects of sodium selenite and sodium selenate applications on laying, plant appearance, number of worm cobs, random number of plants, plant height, cob/plant ratio, leaf/stem ratio of silage maize plant were investigated. Selenium was applied at eight different levels (0-5-10-15-25- 50-75-100 g Se ha-1). Selenite was applied to the soil in liquid form before planting seeds, and selenate was applied to the leaf when the corn plant was 50-70 cm tall. Selenium applications did not statistically affect lying, plant appearance, worm cob number, randomized plant number and plant height values. Selenite applications affected the cob/plant ratio and leaf/stem ratio values statistically, the interaction of the year X subject was significant. In 2013, there was a statistical difference between the subjects, the highest values were obtained with 52% from 5 g Se ha-1 application, with 45% and 47% from 10 g Se ha-1 and 25 g Se ha-1 applications, respectively. Selenate applications did not affect the cob/plant ratio values statistically, but the leaf/stem ratios were affected, the highest values were obtained with 43% from 100 g Se ha-1 applications. It is known that selenium applications do not affect the yield and other plant properties in plants, but increase the selenium concentration of the grain or plant. However, some studies show that selenium application affects positively the plant as our study. It is thought that the effect of selenium in plant development may vary depending on the type and variety of the plant, many factors increase the selenium activity, especially outside the soil and climatic conditions, the application time, rate and method, the form of selenium and the plant species are effective.
