The Effect of Slow-Release Nitrogen Fertilizer Applied At Different Doses and Different Periods on Yield and Yield Components of Dent Corn (Zea mays L. var. indentata)
Journal Title: MAS Journal of Applied Sciences - Year 2023, Vol 8, Issue 3
Abstract
In this study, nitrogen fertilizer was the effect of slow-release nitrogen fertilizer applied at different doses and in different periods on yield and yield components of dent corn was investigated. The experiment was set up in a split plot design with 3 replications in the 2021 growing season in Şanlıurfa second crop conditions. Nitrogen doses were the main plots of the experiment and application times were the sub-plots. Dekalb DKC 6092 dent corn variety was used in the study, as 15 kg/da, 20 kg/da, 25 kg/da and 30 kg/da nitrogen dose and application time at four different rates; Nitrogen dose application times, which consisted of three different periods, were tried when all the plants were 40-45 cm and the other half when the plants were 40-45 cm. Phosphorus was given at 8 kg/da with sowing. As a result of the research; The values obtained from plant stem diameter, ear diameter, number of grains per cob, kernel weight per ear, ear length, hectoliter weight and kernel yield were found to be statistically significant. The highest value in grain yield was obtained as 1270.66 kg/da from a total of 25 kg/da N application, half of which was seeding and half of which was top. As a result of the data obtained, it was determined that the highest grain yield was obtained from 25 kg/da nitrogen application.
