“…Most studies do not report a soybean yield response to Mn applications when the Mn concentration in leaf tissue is greater than 20 to 25 mg kg −1 , with some studies reporting critical values slightly less than that (Alley et al, 1978; Brown et al, 1997; Gettier et al, 1984; Mascagni and Cox, 1985b; Ohki, 1976). Manganese concentrations of 25 mg kg −1 in soybean seed typically indicate adequate Mn as well (Gettier et al, 1984; Mascagni and Cox, 1985b). This would suggest that the Mn concentrations in soybean leaf tissue and seed of this study are adequate and yield responses would not be expected.…”

“…Manganese is essential to ureide degradation and increases in Mn supply have been shown to both reduce ureide accumulation in leaves and increase N fixation in nodules (Purcell et al, 2000). Manganese applications have increased soybean yield by more than 2000 kg ha −1 (Gettier et al, 1985; Mascagni and Cox, 1985a), however, many studies report yield increases between 300 and 1000 kg ha −1 (Heckman et al, 1999; Gettier et al, 1984; Mascagni and Cox, 1985a, Randall et al, 1975; Robertson et al, 1973). Because of the prevalence of GR soybean in the United States and other countries, the possibility of increased yields from GR‐related Mn response could substantially impact production.…”

Manganese Response in Conventional and Glyphosate Resistant Soybean

Fertilizer Management 606A gronomy J our n al • Volu me 102 , I s sue 2 • 2 010 ABSTRACT Glyphosate-resistant (GR) soybean [Glycine max (L.) Merr.] is widely produced and provides many benefi ts to production agriculture, however, recent reports suggest that GR soybean genetics may result in reduced Mn uptake and increased response to Mn fertilization. Th e objective of this research was to determine response of GR and conventional (CV) soybean near-isolines to Mn fertilization. Th e soybean near-isoline pair KS4202 and K4202RR was planted at three locations and near-isoline pair KS4602N and KS4602NRR was planted at two locations in a split-block fi eld study. Manganese treatments consisted of soil-applied MnSO 4 at 0, 2.8, 5.6, and 8.4 kg Mn ha -1 and foliar applied Mn-glucoheptonate at 0.22 and 0.45 kg Mn ha -1 . Leaf tissue was analyzed for Mn at R1, R3, and R6 growth stages and seed was analyzed for Mn at harvest. Manganese concentrations in leaf tissue were above the critical value and were not aff ected by GR genetics at any location or growth stage. However, there were yield responses to Mn applications at three of the fi ve locations. KS4202RR soybean yield increased by 800 and 275 kg ha -1 with increasing Mn application rate at two locations when the near-isoline KS4202 yield did not increase. In contrast, at the third responsive location KS4602NRR did not respond to Mn application when the near-isoline KS4602N yield increased by 450 kg ha -1 . Th ese results indicate that although soybean response to Mn is infl uenced by genetics, neither the Mn uptake nor the Mn responsiveness were conclusively aff ected by glyphosate-resistance in soybean.

“…However, soil applied Mn has a low residual value (Murphy and Walsh, 1973). Gettier et al (1984) reported that on a sandy loam soil 56 kg Mn/ha did not fully alleviate Mn deficiency from one growing season to the next Another problem associated with soil application is the need to accurately locate problem areas prior to planting.…”

“…Foliar application of MnSO4 or Mn EDDHA is most frequently used to control Mn deficiency (Randall et al, 1975;Ohki et al, 1987). Despite the effectiveness of this treatment, multiple applications are generally required to fully alleviate Mn deficiency (Mascagni and Cox, 1985;Ohki et al, 1987;Gettier et al, 1984). …”

Manganese (Mn) deficiency is a problem in soybeans grown on high pH soils, which to date can only be controlled by chemical fertilizers. In view of the success of genetic resistance in reducing yield losses associated with iron (Fe) deficiency chlorosis, a one year study was initiated to determine whether genetic resistance could be used to control Mn deficiency related yield losses. For this study, twenty soybean genotypes ranging from Group I maturity to Group III maturity were planted at five locations which had previously exhibited symptoms of Mn deficiency. Individual plots were rated for Mn-deficiency symptoms on a 1-5 scale (1 = no yellowing to 5 = severe yellowing with some necrosis) at the Rl growth stage and plants in the center rows were harvested for yield. The mean Mn-deficiency rating was 2.8 with a range from 1.8 for NKS 23-03 and P9181 to a 3.9 for A3205. The mean yield was 3059.3 kg/ha with a range from 3670.6 for A3205 to 2567.5 kg/ha for Chapman. The correlation between Mn-deficiency rating and yield was not significant presumably due to the high yields of some of the later maturing cultivars.
