Cropping sequences integrating perennial forages and annual crops can generate multidimensional agroeconomic environmental benefits. A 4-yr cropping sequence study was conducted from 2013 to 2016 evaluate the relative merits of various sequences. Three forage seed (creeping red fescue [Festuca rubra L.], alsike clover [Trifolium hybridum pratense L.]) four food (wheat [Triticum aestivum canola ...

The toric residue is a map depending on n + 1 divisors on a complete toric variety of dimension n . It appears in a variety of contexts such as sparse polynomial systems, mirror symmetry, and GKZ hypergeometric functions. In this paper we investigate the problem of finding an explicit element whose toric residue is equal to one. Such an element is shown to exist if and only if the associated po...

These experiments were conducted to determine metabolizable energy and amino acid digestibilities of soybean meal, sunflower meal and canola meal in broiler chickens by using titanium oxide as indigestible marker in intact or caecectomized cockerels. Ileal and total tract digestibility of amino acids were measured using broiler chickens, moreover, digestibility were also determined in the intac...

The effects of microwave-assisted alkali pre-treatment on pellets' characteristics and enzymatic saccharification for bioethanol production using lignocellulosic biomass of canola straw and oat hull were investigated. The ground canola straw and oat hull were immersed in distilled water, sodium hydroxide and potassium hydroxide solutions at two concentrations (0.75% and 1.5% w/v) and exposed to...

iv ACKNOWLEDGMENTS I would like to thank my advisor Dr. Lili He for her full support and encouragement throughout my research. The experience I gained and opportunities I had in this lab greatly exceeded my expectations, for which I am grateful. I would also like to thank Dr. Decker and Dr. Zhang for being members on my committee and for their input on my thesis. I would finally like to thank D...

Fifty-four Holstein bulls were blocked by initial BW (301 +/- 7.4 kg) and randomly assigned to 6 treatments following a 3 x 2 factorial arrangement, with 3 concentrate lipid levels (5, 8, and 11% of DM) and 2 lipid sources (whole canola seed and whole linseed), with the objective of evaluating the possibility of increasing the content of n-3 fatty acids in meat. Concentrates (mostly corn meal) ...

Adequate nutrition is essential for crop growth, production, and profit potential farmers, but chemical fertilizer costs alone can constitute a greater portion of the total variable wheat canola. The present study evaluated seven cropping treatments (CT) in 3-year rotation under two different soil types. Five CTs consisted one-time application (year 1) beef cattle manure, growing cover cocktail...

Salinity is a major environmental factor that influences rapeseed production in arid and semi-arid regions of central and southern Iran. In this study, effect of applied NaCl on shoot and root growth and distribution and accumulation of Na, Cl, K, Ca and Mg in the canola plant (Brassica napus L. cv: Hayola 308 and cv: PP 401) was investigated. The experiment was arranged in a completely randomi...
