Leaf Area Index Simulation In Soybean Grown Under Near-Optimal Conditions, T. D. Setiyono, Albert Weiss, James E. Specht, Kenneth G. Cassman, A. Dobermann
Leaf Area Index Simulation In Soybean Grown Under Near-Optimal Conditions, T. D. Setiyono, Albert Weiss, James E. Specht, Kenneth G. Cassman, A. Dobermann
Department of Agronomy and Horticulture: Faculty Publications
Different approaches have been used to simulate leaf area index (LAI) in soybean (Glycine max L. Merr). Many of these approaches require genotype-specific calibration procedures. Studies modeling LAI dynamics under optimal growth conditions with yields close to the yield potential of soybean have remained scarce. A sink-driven approach was developed and evaluated for LAI simulation in soybean under near-optimal environments. The rate of change in expanding leaf area was simulated using the first derivative of a logistic function accounting for plant population density, air temperature, and water deficit. The rate of change in senescing leaf area was also simulated …

Although relationships among soybean (Glycine max [L.] Merr) seed yield, nitrogen (N) uptake, biological N2 fixation (BNF), and response to N fertilization have received considerable coverage in the scientific literature, a comprehensive summary and interpretation of these interactions with specific emphasis on high yield environments is lacking. Six hundred and thirty-seven data sets (site–year–treatment combinations) were analyzed from field studies that had examined these variables and had been published in refereed journals from 1966 to 2006. A mean linear increase of 0.013 Mg soybean seed yield per kg increase in N accumulation in above-ground biomass was evident in …
Effects Of Atmospheric Co2 Enrichment On Crop Nutrient Dynamics Under No-Till Conditions, Stephen A. Prior, G. Brett Runion, Hugo H. Rogers, H. Allen Torbert
Effects Of Atmospheric Co2 Enrichment On Crop Nutrient Dynamics Under No-Till Conditions, Stephen A. Prior, G. Brett Runion, Hugo H. Rogers, H. Allen Torbert

Increasing atmospheric CO2 concentration could increase crop productivity and alter crop nutrient dynamics. This study was conducted (3 yrs) with two crops ([Glycine max (L.) Merr.] and grain sorghum [Sorghum bicolor (L.) Moench.]) grown under two CO2 levels (ambient and twice ambient) using open top field chambers on a Blanton loamy sand under no-tillage. Macronutrient and micronutrient concentrations and contents were determined for grain, stover, and roots. Although elevated CO2 tended to reduce nutrient concentrations, high CO2 consistently increased nutrient content especially in grain tissue; this response pattern was more notable with macronutrients. The …
Improvement Of The Nutritional Value Of Soybean [Glycine Max (L) Merr.] Seed With Alteration In Protein Subunits Of Glycinin (11s Globulin) And \Beta-Conglycinin (7s Globulin), Behzad Kaviani, Ardashir Kharabian
Improvement Of The Nutritional Value Of Soybean [Glycine Max (L) Merr.] Seed With Alteration In Protein Subunits Of Glycinin (11s Globulin) And \Beta-Conglycinin (7s Globulin), Behzad Kaviani, Ardashir Kharabian

Protein quality in soybean seeds is strongly influenced by nutritional conditions. Glycinin (11S globulin) and \beta-conglycinin (7S globulin) are the 2 main proteins in soybean seeds. Protein quality of glycinin (11S) is higher than that of \beta-conglycinin (7S), due to the presence of higher amounts of s-containing amino acids (methionine and cysteine) in glycinin than \beta-conglycinin. Of the amino acids in glycinin, 3%-4.5% are methionine and cysteine but these important amino acids are not found in \beta-conglycinin (especially \beta-subunit). Pot studies were conducted with soybean [Glycine max (L) Merr.] grown under various levels of KCl and CaHPO4 and the effects …
