RESUMO:

The objective of this work was to evaluate the effects of a growth biostimulant on the productivity, nutritional value and morphogenesis of Brachiaria urochloa cv. Marandu, evaluated under two levels of nitrogen fertilization. The experiment was conducted at the Federal Rural University of Amazonia, Campus Parauapebas, which has a characteristic dry period (May to October) and a very sharp humid period with torrential rain from November to April. It was designed in a 2x4 factorial scheme, with two doses of nitrogen fertilization (50 and 150 kg N / ha) and four doses of 4 doses of growth biostimulant + leaf fertilizer (0,1,2,3 L / ha). Data were subjected to analysis of variance by the SAS MIXED procedure, using 5% as the critical level of significance, in which the effects of triple interaction and double interactions. No triple interaction (BC + FF x Fertilization x Period; p> 0.05) was observed in any of the production and morphological characteristics of Brachiaria urochloa cv. Marandu There was an increase in DM production per ha / day for fertilization with 50 kg N / ha and possibly an increase in root development due to the presence of auxin. It can be concluded that at low dosages of growth biostimulant there is an increase of DM / ha / day production..
