“…Other researchers showed that in the same cultivar and at the same location, year had significant effects on the total isoflavones concentration, and depending on the year, the range of isoflavone concentrations ranged from 1176 to 3309 μg·g −1 [5], and from 1176 to 1749 μg·g −1 among locations within the same year in the same cultivar [5]. It was also found that seeds exposed to high temperature during seed-fill had lower concentrations of isoflavones compared with those developed in lower temperatures [30,31]. Potassium is a major nutrient for crop growth, development, yield, and quality.…”

“…It was also reported that location had a significant effects on isoflavones, and isoflavone concentration varied from 1176 to 1749 μg·g −1 among locations within the same year in the same cultivar [5]. It was found that seed developed at high temperature during seed-fill had lower concentration of isoflavones compared with seed developed at lower temperatures [30,31]. The increase of individual and total isoflavone concentrations in 2008, 2009, and 2010 in Jackson, and in 2008 and 2009 in Milan with the increase of K fertilizer rates indicated that K can alter isoflavones concentrations.…”

“…For example, it was reported that [26] seed composition varied in the same cultivar grown in different years or under different environments in the same year, and seed protein concentration increased as planting was delayed. Significant ef-fects of genetics and environment on isoflavones [4,5,19,20,[30][31][32] and on sugars [3,19,20] were observed. Isoflavone concentrations were found to vary from 1161 to 2743 μg·g −1 in 210 soybean cultivars [4].…”

Previous research has shown that the effect of potassium fertilizer on soybean ([Glycine max (L.) Merr.] seed composition (protein, oil, fatty acids, and isoflavones) is still largely unknown. Therefore, the objective of this research was to investigate the effects of potassium application on seed protein, oil, fatty acids, and isoflavones under Midsouth environmental conditions. A three-year experiment was conducted in two locations (Milan, TN and Jackson, TN). Potassium (K) rates were applied in the form of K 2 O at a rate of 0 (Control, C), 45 (T1), 90 (T2), 134 (T3), and 179 (T4) kg·ha −1 in a randomized complete block design. The results showed that increasing the K application rate did not result in consistent effects on yield. However, increasing K application rate did increase protein, oleic acid, and individual and total isoflavone concentrations at both locations in 2008 and 2009. In Jackson in 2010, the increase of K rate did not change oleic acid, but resulted in an increase in glycitein and genistein isoflavone concentrations. In 2010, increasing K application rate increased protein concentrations, decreased individual and total isoflavones, and did not change oleic acid concentration at Milan. At the highest rate of K, 179 kg·ha −1 , yield and some seed composition constituents were negatively impacted. Generally, K concentration in leaves at V5, R1, R3, and seed at harvest maturity stage (R8) increased with the increase of K rate applications. The research demonstrated that K application can alter seed composition, but this alteration depended on location, environmental stress factors, mainly heat and drought, K level in soil, and K application rate. Higher rates of K application may negatively impact seed composition constituents.

This study was performed to determine the relative quality of mungbeans harvested in bulk after applying a labor-saving cultivation (LSC) method, compared to mungbeans harvested three different times under the conventional cultivation condition. There was no significant difference in starch, crude protein, and vitexin or isovitexin content of seed according to the cropping system or harvest time. The mungbeans grown under the LSC method had the highest crude fat content, followed by mungbeans from the third-, the second-and the first-harvest mungbeans under the conventional cultivation. No significant difference was found in the composite ratio of saturated fatty acids to unsaturated fatty acids according to cropping system or harvest time. The second-harvest mungbeans grown under the conventional cultivation condition had 17 different types of fatty acids, while the third-harvest mungbeans grown under the conventional cultivation and those grown under the LSC condition had the fewest types of fatty acids with 12. Of the major saturated fatty acids, palmitic acid and arachidonic acid had the highest composite ratio in the first conventional cultivation followed by the second, the third and the LSC. However, stearic acid showed the opposite tendency. Of the major unsaturated fatty acids, linoleic acid had the highest composite ratio in the first conventional cultivation, followed by the second and third conventional cultivation and the LSC. Amylogram characteristics of the mungbeans were significantly different according to cropping system and harvest times. The mungbeans harvested after the first conventional cultivation had significantly higher pasting temperature, peak viscosity, holding strength viscosity, final viscosity and breakdown, while mungbeans harvested after the third conventional cultivation had significantly higher setback viscosity. In contrast, the mungbeans harvested under the LSC methods had a significantly lower amylogram value. When harvest rate, color values and amino acid content of sprout were measured, mungbeans grown under the LSC conditions had a low harvest rate of sprout, but had Hunter's color values and amino acid content of sprout similar to those of mungbeans grown under the conventional cultivation condition.

This experiment was conducted to investigate the variation of anthocyanin, and isoflavone contents in five cultivars and two lines of Korean domestic black soybeans grown at different latitudinal locations, a high latitude, Suwon (37°16'N) and a low latitude, Milyang (35°30'N). Delphinidin-3-glucoside (D3G) contents of anthocyanin in Geomjeongkong # 3 and Ilpumgeomjeongkong, cyanidin-3-glucoside (C3G) content in Milyang # 113, petunidin-3-glucoside (Pt3G) contents in Milyang # 113, and Ilpumgeomjeongkong, and total anthocyanins in Milyang # 113 were highest among the seven black soybean cultivars and lines. D3G, C3G, and total anthocyanins in Geomjeongkong # 3, C3G, and total anthocyanins in Ilpumgeomjeongkong grown at high latitude were higher compared to low latitude. Daidzein, glycitein, genistein, and total isoflavone contents in Geomjeongkong # 4 were highest among the seven cultivars and lines. Daidzein contents of isoflavone in Geomjeongkong # 3, Milyang # 112, and Milyang # 113 grown at high latitude were higher compared to low latitude. Glycitein contents in Geomjeongkong # 3, and # 4 grown at high latitude were higher compared to low latitude, while it in Milyang # 113 grown at low latitude was higher compared to high latitude. Genistein contents in most black soybeans except Milyang # 113, and total isoflavone contents in Geomjeongkong # 4 and Cheongjakong grown at low latitude were higher compared to high latitude. The variations of anthocyanin except Pt3G and isoflavone contents seemed to be affected by environmental conditions like different latitude than the genotype because they showed the significant interaction between cultivars and locations.
