Development of Flaxseed Submitted to Nitrogen Doses 1

[...]the objective was to find the appropriate dose of nitrogen for the development of the variables: technical length, yield length, main stem diameter, number of grains per pod. plant grain yield, and plant dry mass of two flaxseed varieties, brown and golden, in places with subtropical and tropical climate in Brazil. The plant dry mass increased linearly and proportionally to the increase in nitrogen doses in Santa Maria and Frederico Westphalen enviromnents. [...]flaxseed responds differently to nitrogen supplementation according to the cultivation enviromnent. showing wide variability. In Brazil, the average grain yield is around 1,000 kg ha1 (IBGE, 2016), while countries such as Sweden, France. and Canada showed averages of 3,918, 1,931, and 1,543 kg ha1 respectively, evidencing the yield potential of the crop (Popovic, 2016). [...]as in other crops, the flaxseed tends to vary its yield and its phenotypic expression according to the environment in which it is positioned and according to the availability of nutrients in the system, among these nutrients, nitrogen. [...]the objective was to estimate the appropriate nitrogen dose for the development of the variables technical length, yield length, main stem diameter, number of grains per pod, plant grain yield, and plant dry mass of two flax varieties, brown and golden, in places with subtropical and tropical climate in Brazil.
