Nitrogen pools in tropical plantations of N2-fixing and non-N2-fixing legume trees under different tree stand densities. Author(s): BIGHI, K. N.; PAULA, R. R.; CALDEIRA, M. V. W.; BURAK, D. L.; MENDONÇA, E. de S.; SOUZA, P. H. de; DELARMELINA, W. M.; BALIEIRO, F. de C. We investigated the nitrogen pools in monocultures of legume species widely used in reforestation in Brazil that have contrasting growth and nitrogen acquisition strategies. The plantations were estab... ... Repository: BDPA Publication year: 2021
Nitrogen sufficiency index for estimating nitrogen fertilizer requirement of irrigated rice. Author(s): SANTOS, A. B. dos; SILVA, M. A. S. da; SILVEIRA, P. M. da; CARVALHO, G. D.; STONE, L. F. The proper nitrogen management is required to achieve high irrigated rice yield. This study aimed to determine the rice response to nitrogen topdressing doses and calibrate the chlorophyll meter readi... ... Repository: BDPA Publication year: 2019
Effects of glyphosate-resistant gene and herbicides on biological nitrogen fixation symbiotic efficiency and grain productivity of soybean in Brazil. Author(s): HUNGRIA, M.; MENDES, I. C.; NAKATAMI, A. S.; REIS-JUNIOR, F. B.; FERNANDES, M. F. We reported the effects of transgenic glyphosate resistant soybean cultivars (GRC), glyphosateand weed management strategies (glyphosate + GRC vs. conventional herbicides + non-GRC)on biological nitro... ...

Nitrogen-use efficiency of maize genotypes in contrasting environments. Author(s): MARTINS, A. O.; CAMPOSTRINI, E.; MAGALHAES, P. C.; GUIMARAES, L. J. M.; DURAES, F. O. M.; MARRIEL, I. E.; NETTO, A. T. The purpose ofthis study was to evaluate the nitrogen-use efficiency of 15 corn hybrids in different environments. The experiment was conducted at the research station Embrapa Milho e Sorgo, in enviro... ... Repository: BDPA Publication year: 2008
Influence of nitrogen and potassium fertilization on nutrient content of the guava 'Paluma' fruit. Author(s): AMORIM, D. A.; ROSANE, D. E.; SOUZA, H. A. de; MODESTO, V. C.; NATALE, W. Repository: BDPA Publication year: 2012
Cupriavidus necator isolates are able to fix nitrogen in symbiosis with different legume species. Author(s): SILVA, K. da; FLORENTINHO, L. A.; SILVA, K. B. da; BRANDT, E. de; VANDAMME, P.; MOREIRA, F. M. de S. Repository: BDPA Publication year: 2012
genotypes with contrasting biological nitrogen fixation efficiencies differentially modulate nitrogen metabolism, auxin signaling, and microorganism perception pathways. Author(s): CARVALHO, T. G.; ROSMAN, A. C.; GRAVITOL, C.; NOGUEIRA, E. de M.; BALDANI, J. I.; HEMERLY, A. S. Sugarcane is an economically important crop that is used for the production of fuel ethanol. Diazotrophic bacteria have been isolated from sugarcane tissues, without causing visible plant anatomical c... ... Repository: BDPA Publication year: 2022
Do cover crops compete with young grapevines for fertilizer nitrogen? Author(s): BRUNETTO, G.; CERETTA, C. A.; MELO, G. W. B. de; FELIPE, L.; PAULO, A. A. F.; COUTO, R. da R.; SILVA, L. O. S.; SOMAVILLA, L. M.; ADRIELE, T.; GARLET, L. P.; LESSANDRO, D. C.; COMIN, J. J.; LOVATO, P. E. Vineyard soils of the Campanha Gaúcha region of Rio Grande do Sul are sandy and have low to medium organic matter content, displaying low natural ability to supply nitrogen (N). Therefore, maintenance... ... Repository: BDPA Publication year: 2016
Nitrogen recovery efficiency for corn intercropped with palisade grass. Author(s): ALMEIDA, R. E. M. de; FAVARIN, J. L.; OTTO, R.; FRANCO, H.; REIS, A. F. B.; MOREIRA, L. A.; TRIVELIN, P. Intercropping corn and palisade grass is a technique to increase straw production, soil C contents, nutrient cycling and crop yield. However, concerns arise from nitrogen (N) uptake by the intercroppi... ... Repository: BDPA Publication year: 2018
Utilization of nitrogen (15N) from urea and green manures by rice as affected by nitrogen fertilizer rate. Author(s): CONTRERAS ESPINAL, F. S.; SILVA, E. C. da; MURAOKA, T.; FRANZINI, V. I.; TRIVELIN, P. C. O.; TEIXEIRA, M. B.; SAKADEVAN, K. The use of green manures (GMs) in combination with nitrogen (N) fertilizer application is a promising practice to improve N fertilizer management in agricultural production systems. The main objective... ... Repository: BDPA Publication year: 2016
