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 ...
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 ...
