Do nutrient uptakes and grain yields differ between spring barley varieties grown for organic farming as mono-crop and in mixture: Characteristics of spring barley varieties for organic farming

Manure application increased yield. Hence the study was conducted under the conditions of moderate nutrient stress and in all probability nitrogen stress. Under this condition nutrient uptakes, biomass production and grain yields did vary between Otira, Orthega, Landora, Brazil, Svani, NK96-300, Mixture 1 (Otira, Orthega, Landora) and Mixture 2 (Brazil, Svani and NK96-300). Interaction between variety and soil fertility treatments were also significant. These findings open new possibilities for selection or plant breeding for genotypes with improved capability of nutrient acquisition from soils at different soil fertility levels e.g. in organic farming. Cropping of barley varieties in mixtures seems to increase (stimulate) nutrient uptakes (N, P, S, K, Mg, Ca, Mn, Zn, Cu and Mo) and biomass production

Second Session: Gender and Religion

This panel includes topics exploring the relationship between gender and religion. Professor Marie Failinger will analyze the Free Exercise clause in the Constitution through the values found in feminist jurisprudence. Also, Professor Shawn M. Crincoli will contrast how different religious denominations view assigning and reassigning sex, including how sex assignment is viewed under the American legal system. Professor Timothy J. Tracey will explore whether stripping private schools of their tax exempt status is constitutionally permissible if they maintain an opposition to same-sex marriage
