The greatest economic value from a corn (Zea mays L.) crop is obtained when it can be used as silage rather than for grain only. The objectives were to study tropical corn silage yield and quality in relation to starter fertilizer, planting date, corn hybrid, and fall armyworm stress. This study was conducted in the field a t Quincy and Jay, Florida during 1991 and 1992. Results have shown the ...

137 Biochar (BC) was evaluated for nitrogen (N) and phosphorus (P) removal from aqueous solution to quantify its nutrient pollution mitigation potential in agroecosystems. Sorption isotherms were prepared for solutions of ammonium (NH4 +), nitrate (NO3 -), and phosphate (PO4–P) using BC of corn (Zea mays L.) and oak (Quercus spp.) feedstock, each pyrolyzed at 350 and 550°C highest treatment tem...

The objective of this study was to evaluate the potential improving economic value integrated crop-livestock systems (ICLS) compared conventional specialized in monoculture. experimental area 16.02 ha, divided into 18 paddocks 0.89 ha each, organized a randomized block design, with three replicates and six models production systems: crop system [corn ( Zea mays ) grain production], livestock (b...

Wisconsin dairy farmers produce more corn (Zea mays L.) silage than any other state in the U.S. A University of Wisconsin corn silage research consortium evaluated corn hybrids and found that the range for NDF and digestibility among commercial hybrids is narrow, but more importantly, yield and quality differences among corn hybrids were repeatable (Coors, 1996). In 1995, an extension program w...

Pairs of Helicoverpa zea (Boddie) larvae reared on diet-incorporated MON810 transgenic leaf tissue of field corn (Zea mays L.) were observed in the laboratory to characterize effects of sublethal levels of Bacillus thuringiensis variety kurstaki (Bt) Cry1Ab endotoxins on cannibalistic behavior and mortality. Feeding on sublethal levels of Bt corn reduced the frequency of cannibalistic behaviors...

In the present study, the aphrodisiac properties of the purple corn ( Zea mays) in male rats were analyzed. The aqueous crude extract of purple corn (at 25, 50, and 75 mg/kg) was administered to ( a) copulating male rats and ( b) anesthetized and spinal cord transected male rats. Behavioral parameters of copulatory behavior and parameters of the genital motor pattern of ejaculation previous to ...

Fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is a major pest of corn, Zea mays L., and a significant, but more sporadic, pest of cotton, Gossypium hirsutum L., in the Western Hemisphere. Previous studies showed that the cotton infestations primarily involve a fall armyworm subpopulation known as the "corn-strain" for which corn is the preferred host plant. It was ...

In the present study, bioaccumulation of REEs in Zea mays L. (corn plant) has been analyzed. The role of Rare Earth Element (REEs) in physiology and biochemistry of corn plant have been studied. Physiological characters like peroxidase (POD) and superoxide dismutase (SOD) activities, biochemical analysis of chlorophyll, carotenoids and phenol contents have also been carried out. The plant growt...

Female white-tailed deer, Odocoileus virginianus (Zimmerman), were held in small pens and administered doramectin by free choice of doramectin-coated whole kernel corn, Zea mays L., fed ad libitum with 19% protein deer pellets also being fed ad libitum in a separate container. The mean concentration of doramectin in the serum during treatment was 72.8 ppb. The mean doramectin concentration in t...

Lectins extracted from corn (Zea mays L.) kernel with Tris-HCl buffer pH 7.5 were isolated from the crude extract by affinity chromatography on Sepharose 6B-N-acetyl-d-galactosamine and Sepharose 6B-methylalpha-d-mannoside, and also by lectin affinity chromatography using concanavalin A and Lens culinaris lectin as ligands. According to preferential monosaccharide specificity, salt-soluble lect...
