The aim of the study was to determine the effect of nitrogen fertilizer application on fresh ear yield and quality properties in sweet maize in Isparta conditions during the years of 2012-2013. In this research, five different N doses (0, 50, 100, 150 and 200 kg ha(-1)) were applied on the variety of Merit sweet corn. The study was carried out at Agricultural Research and Applied Center of Suleyman Demirel University in Turkey. This research was conducted in randomized block design with three replication. Plant height, first ear height, ear length, ear diameter, single fresh ear weight, fresh ear yield and crude protein ratio were determined. According to results of two years, nitrogen applications increased plant height, ear length, ear diameter, single fresh ear weight, fresh ear yield and crude protein ratio while first ear height was not affected by nitrogen doses. According to results of this research, 150 kg ha(-1) nitrogen application is recommended for high fresh ear yield and quality in sweet maize in Isparta. |
