Agronomic performance of wheat genotypes and the use of nitrogen doses

This work aimed to evaluate the agronomic performance of wheat cultivars and use nitrogen doses. Two experiments took place at Centro de Pesquisas e Resultados Agronômicos das Missões (CEPRAM), in municipality Entre-Ijuís, Rio Grande do Sul, Brazil. Experiment I a randomized block experimental design, evaluating 22 genotypes four replications. II organized factorial arrangement 7 doses x 2 genotypes. The were 0, 25, 50, 75, 100, 125, 150 kg ha-1 two ORS Senna TBIO Audaz, with 4 In 10 plants, randomly collected, each unit evaluated morphological productive variables. Performing Analysis variance Tukey's mean comparison test both experiments. Applying principal component analysis genetic dissimilarity experiment I. cultivar Noble showed characteristics that maximize wheat. There is divergence between for traits. Cultivar enhanced ear length number tillers 44 N 48 ha-1, respectively.
