This article describes the impacts of the seeding rates of seeds and nitrogen fertilizers on the field germination as well as on preservation of plants and forming of the leaf area and dry mass of the rice of Guljakhon variety. With an increase in the seeding rate from 3 to 6 million pieces per hectare, the field germination rate has decreased by 17,9 %, and the survival rate of plants before harvest has improved by 2,4%. Increased levels of nitrogen fertilizers from N90 to N150 have improved the field germination by 1.9 %, and have dropped preservation of plants before harvest by 2,3%. It has been revealed that the plant height (r = 0,49) is positive, the leaf area (r = -0,67), and dry weight of plants (r = -0,73) negatively correlate with the seeding rate. The nitrogen nutrition dose has a positive relationship with the leaf area (r = 0,64), dry weight of plants (r = 0,55) and plant height (r = 0,88).
