2	Variation in the sensitivity of nodulation and nitrogen fixation to nitrate in annual "Medicago" species / by Hossein Heidari Sharif Abad. Heidari Sharif Abad, Hossein January 1994 (has links) Bibliography: leaves 153-179. / xvi, 179 leaves : ill. (some col.) ; 30 cm. / Title page, contents and abstract only. The complete thesis in print form is available from the University Library. / Annual species of Medicago, or medics, are important pasture legumes in the neutral to alkaline soils of southern Australia but their nodulation and nitrogen fixation processes are retarded by soil nitrate. This study ascertains whether an observed tolerance to nitrate among medic species can be substantiated, and attempts to understand the underlying factors responsible. / Thesis (Ph.D.)--University of Adelaide, Dept. of Plant Science, (1995) Medicago.

5	The effects on the performance of broilers consuming calcium, potassium, and sodium nitrates and nitrites from the drinking water Reeder, Julie A. 10 May 1996 (has links) Four experiments were carried out with broiler chicks from day-old to three or four weeks of age to assess the effects of nitrates and nitrites from calcium, potassium, and sodium salts in the drinking water of broilers on growth, body weights, feed utilization, blood chemistries, liver tissues, and lipid oxidation of breast and thigh tissues. Body weights were lower (P<.05) among chicks consuming calcium nitrate than those of chicks consuming sodium nitrate or the control. Chicks consuming calcium nitrate (Ca(NO��)��) at 1000 ppm had lower (P<.05) body weights than those drinking Ca(NO��)�� at 0, 50, or 200 ppm. Broilers receiving 1000 ppm of calcium nitrite (Ca(NO��)��) had depressed body weights when compared to chicks consuming 0, 50, or 200 ppm of Ca(NO��)��. Consumption of sodium nitrate (NaNO��) at 2033 ppm reduced (P<.05) broiler weights in comparison to broilers ingesting 0, 111, or 427 ppm of NaNO��. Feed utilization was less efficient (P<.05) by chicks ingesting Ca(NO��)�� and calcium, potassium, or sodium salts of nitrite when compared with the control. / Graduation date: 1996 Broilers (Poultry) -- Nutrition Nitrates -- Physiological effect Nitrites -- Physiological effect
