Agronomic characteristics of barley cultivars in response to nitrogen fertilization
The aim of this study was to assess the impact of nitrogen doses on the yield of two barley cultivars, namely BRS Brau and BRS Cauê, cultivated in various growing environments in Southern Brazil. The research was conducted during the 2017 harvest season in Alegrete and Pelotas, RS, Brazil. A randomized block design with a factorial scheme of 2 x 2 x 4 (growing environments x barley cultivars x nitrogen doses) was employed, with four replications. Various parameters were evaluated, including plant height, number of tillers per plant, number of ears per square meter, number of seeds per plant, thousand seeds weight (TSW), and yield. The results indicated that the two barley cultivars responded differently to the growing environments and nitrogen doses. In Pelotas, BRS Brau exhibited superior performance in terms of plant height and TSW, while BRS Cauê showed a higher number of seeds per plant and seed yield. Furthermore, the combination of the Pelotas growing environment and a nitrogen dose of 200 kg ha-1 resulted in optimized growth and yield of barley seeds.
