in order to evaluate the yield and advantage of two- and three-species intercropping of sunflower with corn and soybean, an experiment was conducted at the research farm of faculty of agriculture of tabriz university in tabriz, iran 2011. the experiment was arranged based on randomized completely block design with 6 treatments and three replications. treatments were included the pure stand of s...

The relative suitability of potato and crops frequently grown in rotation with potato as hosts for Pratylenchus penetrans was evaluated. Suitability of rye, wheat, corn, oat, sorgho-sudangrass, and potato were compared in pot studies based on ratios of final population : initial population density and densities of nematodes in roots at harvest. Population densities increased more on potato, oat...

Growing interest in biofuel generation with cellulosic biomass from row crop residues necessitates research to investigate biomass and nutrient management systems impacts water quality. The objective of this research was to evaluate the impact of a range of cropping and corn biomass harvest systems on P loss with surface runoff as affected by N-P management based on inorganic fertilizers or liq...

weight resulted in a slight reduction in the true metabolizable energy content of corn.! Since corn's primary contribution to swine diets is energy, we generally think that low-test-weight corn is of lower feeding value than normal-test-weight corn. However, the 1992 corn crop did not exhibit nutrient content typical of lowtest-weight corn. Field observations failed to demonstrate a consistent ...

The present pot experiment was undertaken to investigate the phytoremediation potential of corn and oat in soil. Treatments consisted of four cadmium (Cd) levels (0, 5, 10 and 20 mg l 1) and three irrigation intervals (1, 3 and 7 days), arranged in the form of a complete randomized design with three replications. Corn and oat were harvested after 75 and 90 days, respectively. Transpiration rate...

The base temperature for germination of corn is approximately 10°C, which results in slow germination and emergence of corn crops sown into cool soils. The effects of plant-growth-promoting rhizobacteria (PGPR) and kinetin on grain and sweet corn emergence, plant growth and yield were studied under short season conditions in 1996 and 1997. Two PGPR strains (Serratia proteamaculans 1-102 and Ser...

Intercropping legume with cereal is an extensively applied planting pattern in crop cultivation. However, forage potential and the degradability of harvested mixtures from intercropping system remain unclear. To investigate the feasibility of applying an intercropping system as a forage supply source to ruminants, two consecutive experiments (experiments 1 and 2) involving a field cultivation t...

European corn borer, Ostrinia nubilalis (Hübner), is a major pest of processing snap bean because larvae are contaminants in pods. The incidence of O. nubilalis-contaminated beans has become uncommon in New York, possibly because widespread adoption of Bt field corn has suppressed populations. Snap bean fields located where Bt corn has been intensively grown in space and time may be at lower ri...

Corn starch showed higher fresh paste consistency than wheat starch, and, after aging 24 hr, its gels were more firm at 6% solids or less. Between 7 and 30% solids, gels of wheat starch were more firm than those of corn starch. The lipids in wheat and corn starches were reduced 88-97% by boiling three times in four parts of a 3:1 (v/v) mixture of ethanol/water. Iodine-binding capacity of corn a...

Alfalfa (Medicago sativa L.) and corn (Zea mays are common forage plants for feeding livestock, their effects on soil bacterial organisms have been extensively studied. However, there is little comprehensive research function in a long-term alfalfa monocropping system after insertion fertilization. The of alfalfa–corn rotation (AF: monocropping, RA: rotation) nitrogen fertilization (RA0 RA15) w...
