„Ertekin I. 2022. Influence of nitrogen dose and plant density on yield and quality properties of dual purpose barley grown under Mediterranean conditions. J. Elem., 27(1): . DOI: 10.5601/jelem.2022.27.1.2225”
In recent years, dual-purpose barley cultivation is a common activity, especially in regions with roughage restrictions. However, the appropriate nitrogen dose and plant density are not clear in this cultivation system. Therefore, this study was carried out to determine the effect of different nitrogen doses (0, 60, 120 and 180 kg ha-1) and plant densities (450, 550 and 650 plant m-2) on dual-purpose barley at the Hatay Mustafa Kemal University research field in 2019-2020 and 2020-2021 growing seasons. To evaluate the performance of dual-purpose barley under different nitrogen doses and plant densities, properties of forage yield, quality, nutritive value, grain yield, yield characteristics and grain quality were investigated. Nitrogen doses and plant densities were affected by some forage yield, quality and nutritive value and grain yield and yield parameters. A better forage yield was obtained from dual-purpose barley with nitrogen doses of 120 kg ha-1 and 180 kg ha-1 at 550 plant m-2 and 650 plant m-2 plant densities. Similarly, the same results were obtained in terms of forage quality and nutritive value of dual-purpose barley. In general, yield and yield characteristics of grain obtained from dual-purpose barley were not affected by nitrogen doses and plant densities. However, plant growing years affected some characteristics related to yield and this effect was explained by meteorological factors. As a result, the most appropriate nitrogen dose and plant density were determined as 120 kg ha-1 and 550 plant m-2 in dual purpose barley cultivation in Mediterranean climate regions, respectively.
