A case study on the use of legume crop rotations in sugarcane Open
Growing legume fallow crops has proven to be an important factor in reducing the yield decline effect in sugarcane production. Legumes can also provide a direct economic benefit to sugarcane farmers by providing a source of nitrogen. Furth…
Geographic and Gender Differences in Semiochemicals in Emerging Adult Southern Pine Beetle (Coleoptera: Scolytidae) Open
Six semiochemicals, important in the communication system of southern pine beetle, Dendroctonus frontalis Zimmermann, were isolated from hindguts of individual beetles from Texas, South Carolina, and North Carolina. Females had more cis-ve…
Rotations of Soybean with Two Tropical Legumes for the Management of Nematode Problems Open
The effects of two tropical legumes, American jointvetch (Aeschynomene americana) and hairy indigo (Indigofera hirsuta), in rotations with soybean (Glycine max) on populations of root-knot (Meloidogyne arenaria) and cyst (Heterodera glycin…
Chitinous Materials from Blue Crab for Control of Root-Knot Nematode II. Effect of Soybean Meal Open
The efficacy of mixtures of soybean meal (SBM), urea and a chitinous material (Clandosan 601) derived from blue crab (Callinectes sapidus) wastes for control of Meloidogyne arenaria was studied under greenhouse conditions. Soil amendments …
Apple Thinning by Photosynthetic Inhibition Open
Shading (92%) of `Redchief Delicious' apple (Malus domestics Borkh.) trees for 10-day periods from 10 to 20, 15 to 25, 20 to 30, and 25 to 35 days after full bloom (DAFB) caused greater fruit abscission than shading from 5 to 15, 30 to 40,…
Chitinous Materials from Blue Crab for Control of Root-Knot Nematode. I. Effect of Urea and Enzymatic Studies Open
The efficacy of two chitinous materials (Clandosan(?) 601 and Clandosan(?) 719) derived from blue crab (Callinectes sapidus) wastes for control of Meloidogyne arenaria was studied in a greenhouse experiment. Both materials controlled the n…
Hairy indigo for the management of Meloidogyne arenaria in peanut. Open
Rotation of hairy indigo (Indigofera hirsuta) with 'Florunner' peanut (Arachis hypogaea) was evaluated for the management of Meloidogyne arenaria in a 2-yr (1986, 1987) field experiment at the Wiregrass Substation near Headland, Alabama. S…
Peach Fruit Abscission by Shading and Photosynthetic Inhibition Open
Shading of nectarine [ Prunus persica (L.) Batsch] scaffold limbs 45-58 days after full bloom caused seed discoloration and fruit abscission. Shading of peach [ Prunus persica (L.) Batsch] scaffold limbs from 31-41 days after full bloom ca…
Effect of End-Point Cooking Temperature upon Nutritive Value and Composition of Turkey Meat Open
Broad Breasted White turkeys (two 7.26 kg females per treatment) were roasted in an electric household oven preheated to 177 C (350 F) to end-point temperatures of 74 C (165 F), 79 C (175 F), 85 C (185 F), and 91 C (195 F). Breast and thig…
Amino Acid Content of Broiler, Quail and Duck Skins Open
Broiler, quail and duck skins were analyzed for moisture, fat, protein, and amino acids. Of the three kinds of skins, duck skins contained the lowest moisture (34.1%) and highest fat content (37.8%). Quail skins contained the highest moist…
A Residue and Stability Study of the Insecticide, Supracide, in the Laying Hen Open
ORGANOPHOSPHATES appear to be most promising in the search for effective insecticides that do not leave residues in eggs and tissues. Supracide, one of the newer compounds of this type, has been shown to possess insecticidal properties dif…
Persistence of Heptachlor in Egg Yolks Open
During the conduct of a more involved study on pesticide residues in poultry, the occasion was presented to observe the total depletion time of heptachlor in egg yolk from hens fed low levels of the pesticide in the feed. The results are s…
Heptachlor Persistence in the Alfalfa-Production Environment Open
A field study was conducted to determine the persistence of heptachlor in the environment for alfalfa production when this pesticide was used for control of the alfalfa weevil.The analysis of 1,563 samples of alfalfa hay harvested in the 1…
The amino acid composition of chinchilla fur in relation to the fur-chewing syndrome Open
Amino acids were determined in two types of chinchilla fur (chewed and normal), using three methods for analyses The methods included microbiological assays of Barton-Wright(5) and two column chromatography techniques of Moore and Stein (7…
