The objective of this study was to evaluate the initial growth in seedling rice in relation of the seed treatment with nutrients applied before planting. The experiment was conducted at the Federal University of Tocantins - Campus Gurupi in a randomized block design with three replications, evaluating the Metica variety rice with three seed treatments in six harvest times. The treatments were: 1 - control without application of mineral elements; 2 - application of zinc, boron, molybdenum and sulfur (concentration of 182.4, 7.6, 45.6 and 83.6 g/l, respectably); 3 - application of zinc and boron concentration of 350 and 20 g/kg, respectably). The evaluations were at 6, 10, 14, 18, 22 and 27days after emergence. Seed treatment with nutrients increased growth and vigor of rice in the initial phase of the cycle. The rate of increase of rice plants were influenced by seed treatment, where the combination of Zn+B+S+Mb showed the best results, favoring the growth, mainly, of the root system of plants.
