The Effect of Chemical and Organomineral Fertilizer Treatments on the Yield and Some Yield Parameters of Wheat Plants

Abstract

For sustainable agriculture in harmony with the ecological balance, the use of organic matter and organomineral fertilizers (OMG) is required. In recent years, use of OMG has become widespread. In this study, the effects of OMG and chemical fertilizer use on yield and quality characteristics of wheat plant in 2018-2019 growing period were investigated. In the research, as chemical fertilizers 20-20-0+(25SO₃) and 15-15-15+(20SO₃) base fertilizers and as top fertilizer urea (46% N) were used. As OMG 16-15-0+(10SO₃)+15OM and 12-15-5+(10SO₃)+15OM base fertilizers and fertilizer with 26% N content [(urea + ammonium sulphate) + OM] as top fertilizer were used. Experiment were carried out according to the random blocks. According to the data obtained, when plant height, spike length, spike number in spike, grain number in spike, grain weight in spike, protein content in grain, there is no significant difference between them. But average highest values was found OMG [(16-15-0+(10SO₃)+15OM + (%26 N + OM)] application. The highest protein value in straw was obtained in OMG [12-15-5+(10SO₃)+15OM + (%26 N+OM)] application. In terms of thousand grain weight, the highest average value was obtained in chemical fertilizer 15-15-15+(20SO₃) + (%46 Urea)  application. The difference between grain yield (kg da^-1) and biomass yield (biomas) values obtained from chemical fertilizer applications with OMG is statistically significant, and the highest grain yield was obtained in the application of the [(16-15-0+(10SO₃)+15OM + (%26 N + OM)]. When the data are evaluated in general, it has been observed that organomineral fertilizer applications in wheat plants yield better results than chemical fertilizer applications.
