In a course of the research there was studied the opportunities of use of near infrared spectroscopy at studying of dynamics of nitrogen content changing in green mass of cereals. The researches were realized in the conditions of the Republic of Belarus in 2013-2014. As a material for researchthere was use the samples of winter and spring barley (Hordeum vulgare), triticale and wheat (Triticum) varieties, which were grown in field conditions of the Scientific and Practical Center of the National Academy of Sciences of Belarus for Arable Farming, Zhodino (Belarus). Predictive models of nitrogen content in plants of cereal crops were designed by near infrared spectra using the modified partial least square and artificial neural networks methods. On the basis of calibration characteristics and the results of their testing, the following conclusion was made: the near infrared spectroscopy could be used for the determination of nitrogen content in plants of cereal crops.
