Maize (corn) is one of the most widely grown cereal crops globally. Fungal diseases of maize cause significant economic damage by reducing maize yields and by increasing input costs for disease management. The most sustainable control of maize diseases is through the release and planting of maize cultivars with durable disease resistance. The wheat gene Lr34 provides durable and partial field r...

Three experiments were conducted to study the property of xylanase and the effects of xylanase in wheat-based diets on growth performance of broilers, respectively. Experiment 1 was performed in vitro to evaluate the effect of different pH and temperature on xylanase activity, and to evaluate the enzymic stability under different conditions. The results indicated that the optimum temperature an...

Two experiments were conducted with beef steers (Exp. 1, average BW of 580 kg; Exp. 2, average BW of 247 kg) to evaluate the use of no supplements (CON) or daily supplementation with (OM basis) .34% of BW of cracked corn (CORN), .34% of BW of wheat bran (WBBW), or .48% of BW of wheat bran (WBISO; calculated to be isocaloric to CORN) on digestive responses (Exp. 1) and live weight gain (Exp. 2)....

Zinc (Zn) nutrition is of key relevance in India, as a large fraction of the population suffers from Zn malnutrition and many soils contain little plant available Zn. In this study we compared organic and conventional wheat cropping systems with respect to DTPA (diethylene triamine pentaacetic acid)-extractable Zn as a proxy for plant available Zn, yield, and grain Zn concentration. We analyzed...

24 A study was conducted with Senegalese sole (Solea senegalensis) to determine the 25 apparent digestibility coefficients (ADCs) of protein, phosphorus and energy in 26 practical feed ingredients. The digestible energy (DE) content was also evaluated. 27 Test ingredients were anchovy fishmeal, solvent-extracted soybean meal, corn 28 gluten and wheat meal. Due to their low cohesion, sole faeces...

OBJECTIVE This experiment was to evaluate the effect of different inclusion levels and adaptation periods on digestible energy (DE) and the apparent total tract digestibility (ATTD) of chemical constituents in diets supplemented with wheat bran. METHODS Thirty-six crossbred barrows with an initial body weight of 85.0±2.1 kg were allotted to 6 diets in a completely randomized block design with...

in this research, the effect of crops such as corn, wheat, sugar beet and clover as previous crop on incidence of leaf and crown wart disease of sugar beet was studied. in the first year, corn, wheat, clover and sugar beet were planted as previous crop in a randomized complete block design with four replications. the amounts of turnover of nitrogen to the soil due to crop residue and their effe...

The relation between corn yield and the number of acres in corn on Iowa farms isa matter of considerable interest. If technical and economic conditions were uniform, the presumption wouldbe that corn acreage wouldvary with the productive capacity of the soil. The very existence of different type-of-farming areas in the state, however, indicates non-uniform conditions. The questions arise as to ...

in recent years, rye caused heavy damages in wheat farms in iran. in order to evaluate wheat competitiveness ability against rye, an experiment was conducted in replacement series design. field experiment was carried out at the agricultural and natural resources research station in miandoab during 2009-2010 (for 2 years). the experimental design was a randomized complete block design with 3 rep...

An accurate and management sensitive simulation model for tile-drained Midwestern soils is needed to optimize the use of agricultural management practices (e.g., winter cover crops) to reduce nitrate leaching without adversely affecting corn yield. Our objectives were to enhance the Agricultural Production Systems Simulator (APSIM) for tile drainage, test the modified model for several manageme...
