Plant phosphorus use efficiency in acid tropical soil. Author(s): VASCONCELOS, M. J. V. de; FIGUEIREDO, J. E. F.; OLIVEIRA, M. F. de; SCHAFFERT, R. E.; RAGHOTHAMA, K. G. ABSTRACT - Phosphorus is an essential macronutrient for plant growth and development. However, phosphorus availability is low in many soils, and the plant?s ability to acquire phosphorus from the rhiz... ... Repository: BDPA Publication year: 2022
Genetic control of grain yield and nitrogen use efficiency in tropical maize. Author(s): SOUZA, L. V. de; MIRANDA, G. V.; GALVÃO, J. C. C.; ECKERT, F. R.; MANTOVANI, E. E.; LIMA, R. O.; GUIMARAES, L. J. M. ABSTRACT: The objectives of this work were to study the genetic control of grain yield (GY) and nitrogen (N) use efficiency (NUE, grain yield/N applied) and its primary components, N uptake efficiency... ...

Nutrient use efficiency in agricultural systems: a brazilian perspective. Author(s): BERNARDI, A. C. de C. Most Brazilian soils are deep, highly weathered, acidic, and of low natural fertility. Many strategies have been developed for building soil fertility using lime and mineral fertilizers, particularly... ... Repository: BDPA Publication year: 2024
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
Water use efficiency and supply in agricultural production. Author(s): SIMOES, W. L.; BRITO, L. T. de L.; SILVA, M. S. L. da; MATTHIENSEN, A.; COELHO, E. F.; BARBOSA, R. S.; ARAUJO, G. G. L. de; CAMPECHE, D. F. B.; SANTOS, R. D. dos; MELO, R. F. de This chapter discusses aspects related to the water-use efficiency in irrigated agriculture and animal production, as well as possibilities to use rainwater as a way to reduce the effects of regional... ...

Screening upland rice genotypes for manganese-use efficiency. Author(s): FAGERIA, N. K.; BARBOSA FILHO, M. P.; MOREIRA, A. Manganese (MIi) deficiency in upland rice grown after common bean or soybean, which received adequate rate of liming on highly weathered Oxisols, is observed. A greenhouse experiment was conducted to... ... Repository: BDPA Publication year: 2008
Response of common bean progenies for water use efficiency. Author(s): LIMA, D. C.; ABREU, A. de F. B.; RAMALHO, M. A. P. Our aim in this study was to evaluate common bean progenies for water use efficiency (WUE) and verify if selection carried out under conditions without water limitation reflects the selection carried... ...
