Inoculation Timing Effect On Biological Nitrogen Fixation And Soybean Productivity, M. A. Secchi, A. R. Torres, L. H. Moro Rosso, I. A. Ciampitti
Kansas Agricultural Experiment Station Research Reports
Soybean [Glycine max(L.) Merr.], as other legume species, has the characteristic of fixing nitrogen (N) from the atmosphere via the biological N fixation (BNF) process. When a proper symbiosis relationship between soybeans and specific bacteria has been established, the plants can obtain up to 98% of the total N need. However, several factors can negatively affect BNF, impairing its contribution to nutrient demand and reducing crop productivity. In this scenario, additional inoculation could help the plant to overcome potential N gaps in BNF. Therefore, the goal of this project was to investigate if additional inoculation at different growth …

Nutritional Quality Of Soybean Seeds Relative To Canopy Portion, L. H. Moro Rosso, W. D. Carciochi, I. A. Ciampitti
Kansas Agricultural Experiment Station Research Reports
Soybean [Glycine max(L.) Merr.] seed quality (nutritional composition) is affected by genetic × environment × management (G × E × M) interactions. Even at the plant level, where differences might not be largely apparent, seed quality is known to change. This study aims to 1) compare seed yield and nutritional quality within the vertical profile of soybean plant canopy, and 2) explore potential interactions for different genotypes. A field experiment was conducted in Manhattan, KS, during the 2018 growing season. Treatments were composed by six genotypes and evaluated at four canopy portions: upper, middle, and lower sections of …
