Variable rate application of potassium fertilizer for soybean crop growth in a no-till system. Author(s): BERNARDI, A. C. C.; GIMENEZ, L. M.; SILVA, C. A.; MACHADO, P. L. O. A. Variable rate application of fertilizer has the potential to improve nutrient use efficiency, improve economic returns, and reduce negative environmental impacts. The objective of this study was to ev... ... Repository: BDPA Publication year: 2010
Broadcast fertilizer rate impacts common bean grain yield in a no-tillage system. Author(s): LACERDA, M. C.; NASCENTE, A. S.; CARVALHO, M. da C. S.; MONDO, V. H. V. Increasing fertilizer rates at sowing can provide significant increases in grain yield in vegetable crops. However, very high rates can impair root development because of increased soil salinization i... ... Repository: BDPA Publication year: 2015
Soil carbon fractions in response to mineral and organic fertilizer types and rates. Author(s): OLIVEIRA, G. F. de; MAFRA, A. L.; CORREA, J. C.; HENTZ, P.; CECHETTO, M.; ROTERS, D. F.; PRAZERES, M. S.; ANDOGNINI, J. Abstract: The use of organic fertilizers from pig slurry and poultry litter can increase soil organic carbon and crop productivity. This study aimed to evaluate soil organic carbon fractions and corn... ... Repository: BDPA Publication year: 2023
Rhizobacterium Serratia sp. and phosphorus fertilization rates affect aerobic rice development. Author(s): NASCENTE, A. S.; FILIPPI, M. C. C. de; SOUSA, T. P. de; CHAIBUB, A. A.; SOUZA, A. C. A. de; LANNA, A. C. Beneficial microorganisms participate in different processes that affect transformation of soil nutrients, including phosphorus (P), making them available for plants. However, there are few studies ab... ... Repository: BDPA Publication year: 2020
Application of lime, phosphogypsum and fertilization rates affect soil fertility and common bean development in no-tillage system in a Cerrado Oxisol. Author(s): CARVALHO, M. da C. S.; NASCENTE, A. S. There is a lack of information about the effects of interactions among lime, phosphogypsum (PG) and fertilization on soil fertility and their effects on common bean yields in the tropics. This study a... ... Repository: BDPA Publication year: 2018
Morphogenetic and structural traits of Ipyporã grass subjected to nitrogen fertilization rates under intermittent grazing. Author(s): CAMARGO, F. C.; DIFANTE, G. dos S.; MONTAGNER, D. B.; EUCLIDES, V. P. B.; TAIRA, C. de A. Q.; GURGEL, A. L. C.; SOUZA, D. L. de ABSTRACT- This study examined the effects of annual nitrogen (N) rates of 100 and 200 kg ha-¹ on the morphogenetic and structural traits of Ipyporã grass (Brachiaria brizantha × Brachiaria ruziziensis... ...

Morphogenesis, biomass and nutritive value of Panicum maximum under different shade levels and fertilizer nitrogen rates. Author(s): PACIULLO, D. S. C.; GOMIDE, C. A. de M.; CASTRO, C. R. T. de; MAURÍCIO, R. M.; FERNANDES, P. B.; MORENZ, M. J. F. Panicum maximum is important for cattle production in tropical regions, and it responds well to nitrogen (N) fertilization. Many cultivars have exhibited potential for use in silvopastoral systems, al... ... Repository: BDPA Publication year: 2016
Nitrous oxide (N2O) emissions from soil cultivated with grass Marandu and subjected to rates and sources of N fertilizers in Amazon of Mato Grosso. Author(s): OLIVEIRA, M. O.; NASCIMENTO, A. F. do; PEDREIRA, B. C. e; PEREIRA, D. H.; RODRIGUES, R. de A. R. Nitrogen is the nutrient required for the fodder production, and main sources are urea and ammonium sulfate, with 45% and 24% of N, respectively. The application of nitrogen may greatly increase the p... ... Repository: BDPA Publication year: 2016
Does nitrogen fertilizer application rate to corn affect yield of subsequent soybean? Author(s): CARVALHO, M. da C. S.; HOROWITZ, N.; NASCENTE, A. S.; TEIXEIRA, P. C.
