Productivity of corn and beans as affected by season and source of nitrogen. Author(s): SILVEIRA, P. M. da; NASCENTE, A. S.; CARVALHO, M. da C. S. Enhanced-efficiency fertilizers, which provide a reduction in nitrogen (N) losses, can be a viable alternative for the anticipation of topdressing for the moment of sowing, besides reducing operations... ...

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
Preliminary evaluation of coffee crops under different doses of nitrogen with a spad meter and leaf nitrogen. Author(s): VILELA, V. A. A.; AMARO, A. R. F. V. B. de L.; MORASI, I. M.; MURRER, M. K.; ABREU, P. F. G.; MOLTOCARO, R. C. R.; MORICONI, W.; GONCALVES, J. R. P.; SILVA, L. C. F. da; PACKER, A. P. Abstract: The objective of this study was to establish correlations among the total N and the SPAD read- ings in Coffea arabica leaves. This study is part of a project that aims to evaluate the agrono... ... Repository: BDPA Publication year: 2014
Soybean carbon and nitrogen accumulation as affected by nitrogen supply. Author(s): SOUZA, H. A. de; INKLMAN, V.; SAZON, L. A.; CRISOSTOMO, S. D.; MENZA, N. C. La While carbon (C) markets are booming, there is scarce information about how much C is accumulated and returned to the soil in soybean crops. Soybean residue is also considered a valuable asset because... ... Repository: BDPA Publication year: 2024
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
Portable chlorophyll meter can estimate the nitrogen sufficiency index and levels of topdressing nitrogen in common bean. Author(s): SILVEIRA, P. M. da; GONZAGA, A. C. de O. The nitrogen sufficiency index (NSI) obtained by using a portable chlorophyll meter is a practical alternative to evaluate the N levels in plants. This study aimed at determining the appropriate NSI v... ... Repository: BDPA Publication year: 2017
Nitrogen sources on agronomic traits in carioca common bean lines developed under mineral nitrogen fertilization. Author(s): DIAS, P. A. S.; MELO, P. G. S.; FERREIRA, E. P. de B.; MELO, L. C.; SOUZA, T. L. P. O. de; FARIA, L. C. de; ALMEIDA, V. M. de; PEREIRA, H. S. Despite the importance of symbiotic nitrogen fixation (SNF) as a nitrogen source for leguminous plants, there are few reports of common bean breeding programs aiming at efficiency in SNF. This study a... ... Repository: BDPA Publication year: 2024
Phylogenetic analysis of nodulation and nitrogen fixation genes of a brazilian collection of Bradyrhizobium strains. Author(s): MENNA, P.; RIBEIRO, R. A.; HUNGRIA, M. The genus Bradyrhizobium encompasses a variety of bacteria that can live in symbiotic and endophytic associations with legumes and non-legumes, and are characterized by physiological and symbiotic ver... ...
