 10:30-10:45     Abdullah Jaradat (USDA-ARS Morris, MN) - Macro- and micro-nutrient dynamics in response to abiotic stress.

Macro- and Micro-nutrient Dynamics in Response to Abiotic Stress.  Eleven genotypes of Zea mays ( two hybrids and an open-pollinated landrace), Cicer arietinum (Kabuli and Desi types), Carthamus tinctorius (two high Omega-3 hybrids), Triticum spp. (aestivum and durum), and Glucine max (conventional and organic genotypes), respectively producing carbohydrates (CHO), proteins (PRT), lipids (OIL), CHO-PRT, or OIL-PRT as the main biochemical seed components (Product) were subjected to four combinations of abiotic stresses imposed by planting dates (normal and 25% less growing degree days than normal) and population density (normal seeding rate and 25% above normal) (Management). The same genotype was planted on the same land area for three consecutive years as an additional abiotic (edaphic) stress (Phase I), then for three more years in a crop rotation (Phase II) to alleviate the previous edaphic stress. Each crop was managed according to its agronomic requirements in the upper Midwest.  At full maturity, and for the purpose of this part of the study, seed samples were assayed for macro- and micro-nutrients (Carbon, C; Calcium, Ca; Copper, Cu; Iron, Fe; Magnesium, Mg; Manganese, Mn; Nitrogen, N; Phosphorus, P; Potassium, K; Sulfur, S; and Zinc, Zn) using LECO analyzer for C and N, and ICP instrument for the remaining nutrients.  A nutrient quality index (QI) was calculated for each Product on the basis of seed chemical composition and was subjected, along with macro- and micro-nutrients, to (1) Principal Components Analyses (PCA) to differentiate between Products; (2) variance components analysis (VarCopm) using Phase, Product, Management and their interactions as fixed factors; Year x Product (Phase), and Year x Product x Management (Phase) as random factors; and C:N ratio as a covariate; (3) Discriminant analysis (Discrim) to identify nutrients significantly contributing to maximum discrimination between Products; and (4) Partial Least Squares (PLS) regression to estimate each nutrient as a function of all other variables and factors in the study. A multivariate map was developed using results of these analyses procedures to illustrate the dynamics of macro- and micro-nutrients in response to multiple abiotic stresses.

The awards were $200 for first, $100 for second and $50 for third. Congratulations to all the students who participated in the competition and special thanks to the judges.

Faculty, please forward this email to your students as I may not have all of their email addresses.

Jeff Vetsch,
Sensor based nutrient management chair,

Graduate students are encouraged to bring research posters for display (4’ × 4’) and there will be a poster competition with prizes.

As in past years there is NO REGISTRATION FEE for this workshop. Early registration for the workshop is encouraged.

To register for the conference send an email to Jeff Vetsch (jvetsch@umn.edu).

If you would like to give a presentation at the workshop (poster or oral) please send me (Jeff Vetsch) your title and authors.
