Resumo: O nitrogênio é um nutriente limitante ao crescimento de varias culturas, entre elas a linhaça. Este trabalho teve como objetivo, verificar as respostas fenotípicas, quando submetida a diferentes doses de fertilizante nitrogenado na forma de uréia, no crescimento da cultura de linhaça. O experimento foi conduzido no município de Cascavel no estado do Paraná, Brasil. Os tratamentos considerados foram os seguintes: T1: testemunha; T2: 25; T3: 50 e T4: 75 kg ha-1 N na forma de uréia. A semeadura foi realizada em uma área de 2,56 m2. Após 120 dias de cultivo foram realizadas as análises das seguintes variáveis altura de planta, número de cápsula, massa fresca e massa seca da parte aérea.

Palavras-chave: Linum usitatissimum, macronutriente, uréia

 

Abstract: Nitrogen is a limiting factor to the growth of several crops, including linseed. This study aimed to verify the phenotypic responses when subjected to different doses of nitrogen fertilizer, under urea form, in the culture growth of linseed. The experiment was conducted in Cascavel in the state of Paraná, Brazil. The treatments were: T1: control, T2: 25, T3: 50 and T4: 75 kg ha-1 N under urea form. It was used an area of 2.56 m2. After 120 days of cultivation were analyzed the variables: plant height, number of capsules, and fresh and dry weight of shoots.

Key words: Linum usitatissimum, macronutrient, urea
