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). ... -
Nutritional and environmental effects on biological nitrogen fixation in soybean: a meta-analysis
Santachiara, Gabriel; Salvagiotti, Fernando; Rotundo, José Luis (Elsevier, 2019-07)Biological N2 fixation (BNF) and mineral soil absorption are complementary N sources for soybean growth. BNF is sensitive to nutrient and environmental conditions, though a comprehensive synthesis of the studies underlying ... -
Relative importance of biological nitrogen fixation and mineral uptake in high yielding soybean cultivars
Santachiara, Gabriel; Borrás, Lucas; Salvagiotti, Fernando; Gerde, José Arnaldo; Rotundo, José Luis (2017-09)Backgrounds and aims: Soybean yield depends on total N uptake, N use efficiency, and harvest index. Nitrogen uptake relays on biological fixation (BNF) and soil absorption. Usually, BNF is considered a yield-related process. ... -
Spatial and temporal plant-to-plant variability effects on soybean yield
Masino, Alejandra; Rugeroni, Pablo; Borrás, Lucas; Rotundo, José Luis (2018-08)Plant density and row spacing are management practices that farmers use to maximize soybean (Glycine max (L.) Merr.) yield. Other canopy aspects related to seedling establishment like spatial (spacing among plants) and ...
