Diet and diabetes
1985
Bierman, E.L.
Nutritional recommendations and diets for diabetic management are reviewed and discussed. The beneficial effects of dietary carbohydrates on glucose tolerance and insulin sensitivity have been demonstrated, and higher carbohydrate, lower fat and cholesterol diets appear to reduce atherosclerosis risk in diabetics over the long term. Such high carbohydrate diets can improve a variety of metabolic abnormalities associated with the diabetic state. These diets are gradually being accepted by physicians, dietitians, diabetes educators, and diabetics. Data to support this change are presented. Current nutritional recommendations for both insulin-dependent and non-insulin dependent diabetes are discussed. While these diets urge the replacement of fat calories with carbohydrate calories, the recommendations call for no increase in total calories consumed. Since wheat products contain both starches and plant fiber, their inclusion in diabetic diets may be beneficial.(wz)

1985
Undersander, D. J. | Reiger, Cecil
Where furrow irrigation is practiced, the residue from the previous crop must be removed from the soil surface to prevent furrow blockage, resulting in disuniform irrigation. High energy and labor costs have caused some producers to consider burning the residue rather than incorporating it. Thus, a 14-year study was conducted on a clay loam soil (fine, mixed, mesic Torrertic Paleustall) in north Texas to test the long-term effects of straw management on land cropped continuously to irrigated winter wheat (Triticum aestivum L). The study included three management treatments: i) residue incorporated into the soil, ii) residue mechanically removed, and iii) residue burned. All other management practices were identical. All treatments caused the soil organic matter in the top IS cm to increase from 1.29 2 years after being broken from native sod to 2.11% during the study. Incorporation of wheat residue did not increase soil organic matter to a greater extent than burning or removing wheat residue. Soil water infiltration was not affected by burning. While grain yield showed considerable variation among years, there were no differences in yield attributable to burning or incorporation of wheat residue.

Reflections on foot rots of wheat in warmer, nontraditional wheat-growing climates
1985
Dubin, H.J. (CIMMYT, Quito (Ecuador). Wheat Program)
Information is presented on Sclerotium rolfsii, Rhizoctonia solani, and Helminthosporium sativum foot rots in warmer areas. It is noted that the facultative nature of most foot rot pathogens may facilitate their moving from rotation crops to wheat in tropical areas. Effective control may require the integration of breeding for resistance or tolerance, appropriate agronomic practices, and chemical or biological control

1985
Wicker F.R.
DEUTSCH: Kurzer Einblick in die Entwicklung der landwirtschaftlichen Forschung bzw. Weizenzuechtung in Mexiko. Mexiko nimmt eine fuehrende Stellung auf diesem Gebiet ein. Es wird geschaetzt, dass heute 35 Mio ha des Weltweizenanbaus mit Sorten vorgenommen wird, die direkten mexikanischen Ursprungs sind. Die gezielte landwirtschaftliche Forschung in Mexiko geht auf das Jahr 1906 zurueck. In den Forschungsinstituten arbeiten heute Wissenschaftler von internationalem Rang aus vielen Laendern. Von Mexiko aus traten die kurzstrohigen Zwergweizen ihren Siegeszug in alle Welt an. Im Jahre 1984 war Mexiko Selbstversorger bei Weizen. Bei der Einlagerung wird der Weizen in fuenf Gruppen eingeteilt: Gruppe 1 (Fuertes) = Weizen mit starkem, elastischen Kleber, Gruppe 2 (Medio) = Weizen mit mittelstarkem Kleber, Gruppe 3 (Suaves) = Weizen mit schwachem Kleber, Gruppe 4 (Tenaces) = Weizen mit kurzem, zaehen Kleber, Gruppe 5 (Cristalino) = Hartweizen (Durum).
