Resumo: 	ABSTRACT The use of growth regulator in oats can reduce plant lodging with reflections in biomass and grain yield. The objective of the study was to determine the feasibility and efficiency of using Trinexapac-Ethyl regulator in the growth of white oat under different conditions of N-fertilizer and years favorable and unfavorable for cultivation. In this study, two experiments were conducted in the years 2011, 2012 and 2013, one for quantifying biomass production rate and the other for the determination of grain yield and lodging. The experimental design was randomized blocks with four replicates, in a 4 x 3 factorial scheme, for growth regulator doses (0, 200, 400 and 600 mL ha-1) and nitrogen doses (30, 90 and 150 kg ha-1), respectively. There is a linear reduction of biomass rate with the increase in the growth regulator dose in oat, regardless of the condition of year and use of N-fertilizer. The growth regulator dose of 495 mL ha-1 efficiently reduces lodging with reduced, high and very high use of N-fertilizer, without reducing the yield of oat grains, in favorable, intermediate or unfavorable year for cultivation.
