Relative importance of biological nitrogen fixation and mineral uptake in high yielding soybean cultivars
(2017-09)
Backgrounds and aims: Soybean yield depends on total N uptake, N use efficiency, and harvest index. Nitrogen uptake relays on biological fixation (BNF) and soil absorption. Usually, BNF is considered a yield-related process. ...
Agronomic performance of maize (Zea mays l.) genotypes under azospirillum brasilense application and mineral fertilizationRendimiento agronómico de genotipos de maíz (Zea mays l.) bajo la aplicación de azospirillum brasilense y fertilización mineral
(2021-01-01)
Maize has a high nitrogen (N) demand; as a result, more sustainable alternatives are needed to reduce demand for mineral fertilizers. The hypothesis is that the agronomic performance of maize genotypes diverges in their ...
Nitrogen Mineralization and Sugarcane Growth in Soils Fertilized with Vinasse
(2020-01-01)
Ethanol production is responsible for the generation of significant amounts of vinasse, a liquid organic waste that contains high concentrations of nitrogen (N). Its direct application in the soil is widely performed in ...
Sustainable production of common beans: inoculation, co-inoculation and mineral fertilization in early-cycle cultivars
(2020-01-01)
Using sustainable management to maximize crop yield without increasing production costs is one of the great challenges of modern agriculture. This study aimed to evaluate the effect of nitrogen (N) supply management, ...
Contribution of nitrogen mineralization indices, labile organic matter and soil properties in predicting nitrogen mineralization
(Sociedad Chilena de la Ciencia del Suelo, 2018-03)
The objectives of this study were i) to measure the nitrogen (N) mineralization potential; ii) to evaluate N mineralization indices and labile soil organic matter (SOM) fractions, and iii) to analyze their interrelationship ...
Composted sewage sludge in replacement of mineral fertilization on wheat production and development
(2016-07-01)
Several research lines are required to ensure a proper disposal of sewage sludge in Brazil; among them, we may highlight agricultural use. In this sense, this study aimed at assessing the effect of exchanging nitrogen ...
Effect of conservation agriculture on soil organic carbon dynamics and mineral nitrogen under different fertilizer management practices in maize (Zea mays)-wheat (Triticum aestivum) cropping system

Orchid in vitro growth as affected by nitrogen levels in the culture medium
(Associação Brasileira de Horticultura, 2012-03-01)
O cultivo in vitro de plantas é o principal método de propagação das plantas da família Orchidaceae, sendo o nitrogênio o nutriente de maior importância dos meios de cultivo. O estudo teve como objetivo avaliar o efeito ...
Nitrogen fertilization of fall panicum cultivars (Panicum dichotomiflorum Michx.): biochemical and agronomical aspects
(Universidade de São Paulo (USP), Escola Superior de Agricultura Luiz de Queiroz (ESALQ), 2004-02-01)
São escassas as informações sobre cultivares melhoradas e técnicas culturais adequadas à cultura do painço. Este experimento objetivou avaliar o efeito da aplicação de níveis de nitrogênio (N) em cobertura no desenvolvimento ...
