Abstract: The aim of the present study was to evaluate the response of different doses and sources of nitrogen (N) on agronomic characteristics in upland riceas well astheclimaticand environmentalinfluence on nitrogen fertilization results. Theexperiments were conducted in the University of Lavras, during 2015/2016 and 2016/2017 crop seasons, the plots consisted of 4 lines of 3 linear meters, with spacing among rows of 35 cm and a useful plot of 4.2 m2. The experimental design was a randomized complete block design with three replications in a 4x4x 2factorial design. The factor doseconsisted in 0, 50,100 e 200 kg ha-1N and the factor sourcesconsisted in ammonium nitrate, ammonium sulphate, urea and polycote, totaling 16 treatments. The characteristics evaluatedwere plant height, grain yield, grain chalkness, 1000 grainsweight andyield. It was concluded that the addiction of doses and Nsources didnot change the agronomic performanceof the upland rice crop. There is an influence of the environment on the responses of plants to nitrogen application, being observed different results in different cropseasons.
