Common bean yield as affected by in furrow filler liming and nitrogen topdressing. Author(s): SILVA, J. G. da; FERREIRA, E. P. de B.; NASCENTE, A. S. The use of filler liming in the sowing furrow can improve the chemical characteristics of the soil and, together with nitrogen fertilization, increase common bean yield. The objective of this study wa... ... Repository: BDPA Publication year: 2021
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
Application stages and nitrogen sources in topdressing of super-early bean crop irrigated. Author(s): SILVA JÚNIOR, J. L. da; BRAZ, A. J. B. P.; BOLDRIN, P. F.; FERREIRA, C. J. B.; SILVEIRA, P. M. da Producing food in a sustainable manner, exploiting the genetic potential of crops and optimizing cultivation time to ensure increased production are the biggest challenges for agriculture. The cultiva... ... Repository: BDPA Publication year: 2020
