MORPHOGENESIS, STRUCTURAL CHARACTERISTICS AND FORAGE ACCUMULATION OF Megathyrsus maximus BRS ZURI SUBJECTED TO NITROGEN FERTILIZATION
(Inst Zootecnia, 2020-01-01)
Nitrogen fertilization permits to increase the carrying capacity of pastures; however, the use of high doses can have negative effects on the growth of forage grasses. Therefore, the aim of this study was to evaluate the ...
Nitrogen fertilisation efficiency and wheat grain yield affected by nitrogen doses and sources associated with Azospirillum brasilense
(2019-10-03)
The nitrogen fertilisation management should focus on increasing fertilisation efficiency in favour of a more sustainable and productive agriculture. Thus, this study aimed to evaluate the effect of inoculation with ...
Measurements and modeling of reactive nitrogen deposition in southeast Brazil
(2011)
Increased reactive nitrogen (Nr) deposition due to expansion of agro-industry was investigated considering emission sources, atmospheric transport and chemical reactions. Measurements of the main inorganic nitrogen species ...
WHEAT NITROGEN FERTILIZATION UNDER NO TILL ON THE LOW ALTITUDE BRAZILIAN CERRADO
(Taylor & Francis Inc, 2014-01-01)
This study evaluates the effects of different nitrogen (N) rates (0, 50, 100, 150, and 200 kg ha(-1)) and sources (ammonium sulfate, urea, and ammonium sulfonitrate with a nitrification inhibitor, Entec (R)) applied either ...
Nitrogen maintenance requirements and potential for nitrogen retention of pullets in growth phase
(Wiley-Blackwell, 2019-07-01)
Experiments were conducted to estimate daily N maintenance requirements (NMRs) and the genetic potential for daily N retention (NRmaxT) of pullets in growth phase. Three nitrogen balance trials were conducted, and a total ...
