Contrasting effects of phosphorus and potassium deficiencies on leaf area development in maize
Arias Usandivaras, Luis María; Gutierrez Boem, Flavio Hernán; Salvagiotti, Fernando (Crop Science Society of America, 2018-10)Management of P and K in agricultural systems is similar, since both move mainly by diffusion in soil. In maize (Zea mays L.), radiation capture is a consequence primarily of leaf area formation and senescence, but little ... -

Contribution of different sources and origins of nitrogen in above- and below-ground structures to the partial nitrogen balance in soybean
Kehoe, Esteban; Rubio, Gerardo; Salvagiotti, Fernando (Springer, 2022-04)Aims: Most studies that quantified the biological N fixation (BNF) and partial N balances of soybean have ignored the belowground structures. Our objectives were to evaluate the contribution of belowground structures to ... -

Desarrollo de bases para el manejo nutricional del cultivo de la arveja (Pisum sativum, var sativum)
Prieto, Gabriel Maria (Facultad de Agronomía, Universidad de Buenos Aires, 2021)El cultivo de arveja en Argentina se concentra en el sudeste de Santa Fe y nordeste de Buenos Aires, cuya producción se destina principalmente a la exportación, y en menor medida al consumo interno como grano seco rehidratado ... -
Does biological nitrogen fixation modify soybean nitrogen dilution curves?
Santachiara, Gabriel; Salvagiotti, Fernando; Gerde, José Arnaldo; Rotundo, José Luis (2018)Biological nitrogen fixation (BNF) in soybean [Glycine max (L.) Merr.] represents, on average, 60% of total nitrogen (N) uptake. Nitrogen dilution curves link aboveground crop N concentration (%N) to biomass accumulation (W). ... -
