“…The year and replication (nested within the year) were considered random effects. This statistical model was similar to that used by Parvej et al (2015), in which the year and replication were considered random effects. When the F-test result of the ANoVA exceeded the .05 probability level, significance (p < .05) was explored by Fisher's protected least significant difference (LSD).…”

Early planting contributed to increased soybean yields in the U.S. Because a double-cropping system dominates in southwestern Japan, early planting is not performed; it is thus unclear how much the yield potential could be increased by early planting. To address this question, we planted seven U.S. and five Japanese cultivars on around 20 May (early planting), measured the agronomic traits, including yield, yield components, and oil and protein contents, and compared these traits with those of the same cultivars planted on around 20 July (normal planting). In the early planting, the yields of the U.S. cultivars were 322-453 g m −2, whereas the highest yield among the Japanese cultivars was only 315 g m , and oil contents, but negatively correlated with the sterile pod rate, 100 seed weight and protein content. In the early planting, the U.S. cultivars had greater pods m −2 , seeds pod −1 and oil content and less sterile pod rate, 100-seed weight, and protein content than the Japanese cultivars. These results suggest that early planting can increase the yield in southwestern Japan, if cultivars with agronomic traits observed in the U.S. cultivars of this study are grown.

“…The higher soybean seed yield and lower nutrient accumulation in the determinate growth cultivars may have resulted from lower biomass production, resulting in lower energy and nutrient expenditures by the plants and increased seed production (Fernandes & Souza, 2006). Soybean cultivars with indeterminate growth habits produce more nodes, fewer lateral branches, and fewer pods (Parvej, 2015;Parvez et al, 1989). Therefore, higher plant densities are needed to obtain satisfactory yields.…”

Sustainable agricultural systems are necessary to improve soybean [Glycine max (L.) Merr.] seed yield and to increase nutrient use efficiency. Intensification of agricultural systems is an important tool to increase farmers’ profitability in the Cerrado region (Brazil), where soybean is rotated with corn in the same growing season. However, this intensification requires soybean cultivar with short growing periods which is achieved by indeterminate soybean cultivars. There is a lack of information regarding the nutrient uptake by soybean cultivars under intensive agricultural systems in the Cerrado. We sought to investigate soybean biomass production and soybean seed yield of determinate and indeterminate soybean cultivars. We also aimed to quantify the amounts of nutrients taken up by soybean biomass and seeds. Field research was conducted to evaluate 17 soybean cultivars commonly grown by farmers, and we considered the determinate and indeterminate soybean growth habit. Nutrient uptake and aboveground soybean biomass were higher under shorter soybean growth and development cycles. Nitrogen, phosphorus and potassium extraction in modern cultivars was higher than in cultivars used in past decades. Nutrient use efficiency was higher in determinate soybean cultivars than in indeterminate soybean cultivars.

“…Neither of the abovementioned studies characterized historical trends of nutrient uptake nor nutrient stoichiometry. Furthermore, published studies on soybean plant nutrition have largely focused on individual nutrients, mostly on N (Fabre and Planchon, 2000;Salvagiotti et al, 2008Salvagiotti et al, , 2009Jin et al, 2011;Rotundo et al, 2014;Van Roekel and Purcell, 2014;Divito et al, 2016;Cafaro La Menza et al, 2017), less on P (Pan et al, 2008;Wang et al, 2009Wang et al, , 2010van de Wiel et al, 2016), and a few on K (Pettigrew, 2008;Parvej et al, 2015). Nutrient stoichiometry is useful to understand crop nutrient status, and nutrient ratios can be useful to comprehend nutrient supplies (Mo et al, 2015).…”

Shifts in Soybean Yield, Nutrient Uptake, and Nutrient Stoichiometry: A Historical Synthesis‐Analysis

Few studies have investigated changes over time in nutrient uptake and yield, in addition to the study of nutrient stoichiometry as a metric of nutrient limitations in soybean [Glycine max (L.) Merr.]. A comprehensive synthesis‐analysis was performed by compiling a global historical soybean database of yield, total biomass, and nutrient (N, P, and K) content and concentration in studies published from 1922 to 2015. This period was divided in three eras based on genetically modified soybean events: Era I (1922–1996), Era II (1997–2006), and Era III (2007–2015). The main findings of this review are: (i) seed yield improved from 1.3 Mg ha−1 in the 1930s to 3.2 Mg ha−1 in the 2010s; (ii) yield increase was primarily driven by increase in biomass rather than harvest index (HI); (iii) both N and P HIs increased over time; (iv) seed nutrient concentration remained stable for N and declined for both P (18%) and K (13%); (v) stover nutrient concentration remained stable for N, diminished for P, and increased for K; (vi) nutrient ratios portray different trends for N/P (Era I and III > II), N/K (Era I > II and III), and K/P (Era II and III > I); (vii) yield per unit of nutrient uptake (internal efficiency) increased for N (33%) and P (44%) and decreased for K (11%); and (viii) variations in nutrient internal efficiency were primarily explained by increase in nutrient HI for N and K, but equally explained by both HI for P and seed P concentration. These findings have implications for soybean production and integrated nutrient management to improve yield, nutrient use efficiency, and seed nutrient composition.
