Resumo: |
Rice cultivation upland stands out in the Cerrado region and on the climatic conditions of the region, management studies of nitrogen fertilization become essential for greater efficiency in the use of this nutrient. The aim of this study was to evaluate the response of cultivating upland rice BRS-Emerald to different nitrogen sources and doses in the Brazilian Cerrado. The experiments were conducted in Goiânia, GO in the agricultural years of 2013/2014 and 2014/15 in Oxisol. The experimental design was a randomized complete block in a factorial 3x4 + 1 (3 fonts, 4 doses and control without N) with four replications. The nitrogen sources used were conventional urea (Uconv); urea treated with NBPT® urease inhibitor (NBPT) and coated urea Kimcoat® polymers (N+) tested in doses 30, 60, 90 and 120 kg ha-1 of nitrogen in rice upland BRS Esmeralda spacing 0.5 m between rows. For the characteristics evaluated nitrogen source NBPT was superior to other sources in the development of rice cultivar BRS Esmeralda. For the characteristics evaluated the soil quality bioindicators little or nothing were influenced by nitrogen source, the biomarkers were more influenced by the planting period and doses of nitrogen applied. |
