Adubação nitrogenada à taxa variada com o N-Sensor nas culturas do milho e trigo
(Universidade Federal de Santa Maria, 2010-03-03)
Most tropical and subtropical soils present insufficient availability of nitrogen (N) to meet the demand of maize and wheat in order to obtain high yields. The N in plants can be evaluated through the use of sensors of ...
Fertilização nitrogenada à dose variada na cultura do milho
(Universidade Federal de Santa Maria, 2014-02-25)
Maize is the main cereal produced in Brazil, being highly responsive to nitrogen fertilization, since the tropical and subtropical soils presents insufficient availability of nitrogen (N) to attend the culture demand in ...
Distribuição espacial de plantas na fileira e sua relação com a produtividade da cultura do milho
(Universidade Federal de Santa Maria, 2015-01-12)
Decreased variability in the distribution of plants on line and increased nitrogen fertilization efficiency are important order management for high yields in corn. The objective of this study was to evaluate the quality ...

(Universidade Federal de Santa Maria, 2015-07-17)
New technologies are intended to assist the farmer in the inoculation process, as is the case of antecipated inoculation (pre-inoculation) provided by using osmoprotectors. In search of higher yields, the kind of inoculation ...
Adubação orgânica em condições de irrigação suplementar e seu efeito na produtividade da quinua (Chenopodium quinoa Willd) no planalto da Bolívia
(Universidade Federal de Santa Maria, 2012-08-24)
Quinua (Chenopodium quinoa Willd.) is an Andean grain with high protein content (14%), and it is one of the main crops that generate incomes for Bolivian plateau farmers. The quinua crop grows in conditions of low temperature, ...
Produção de biomassa, composição química e decomposição de resíduos culturais da parte aérea e raízes no solo
(Universidade Federal de Santa Maria, 2014-02-27)
Crop residues (CR) from shoots (S) and roots (R) of plants are the main source of
carbon C (C) and nitrogen (N) for the agricultural soils. Compared to the S of plants there are
