Abstract

The purpose of the study was to identify forage plants and specialized entomophages of wheat thrips in agrocenoses of winter and spring grain crops cultivated in the Samara region. The highest number of adult pests was noted in winter wheat crops (2365.0 ind./100 strokes), the lowest in winter barley crops (565.0 ind./100 strokes). Egg laying by wheat thrip females occurred on all grain crops. Larvae of wheat thrips were noted in the ears of winter and spring wheat, triticale, and winter barley, with the exception of spring barley. During the research, two specialized entomophages were identified: striped thrips and predatory thrips. During the research years, the largest numbers of predatory thrips were noted in winter wheat crops in the earing phase (90 ind./100 strokes) and in spring wheat and spring barley crops in the booting phase—75 ind./100 strokes and 40 ind./100 strokes, respectively. The damage to winter wheat grain by wheat thrips varied from 55.3% to 69.2% and was higher than the damage to spring wheat grain (38.5–64%). With a certain ratio of specialized entomophages and wheat thrips, it is possible to refuse the use of insecticides in the cultivation of grain crops. [ABSTRACT FROM AUTHOR]

3. The Efficiency of Potassium Fertilizer Use in Western Siberia.

Abstract

A brief review shows that application of K fertilizer to cereal crops grown on soils of Western Siberia can contribute to 20 to 30% yield increases. Field experiments conducted in 'cereals-fodder crop' systems suggest a trend towards higher yields due to K application in both first spring wheat or spring barley crops. A significant yield response to K was obtained for second spring wheat and forage crops of maize or oat-pea mixes. Significant increases in carrot and potato yields were observed within the 'vegetable-potato' cropping system even at the lowest K rates. [ABSTRACT FROM AUTHOR]

4. Progress in Wheat, Sunflower, and Sugar Beet Cultivation in Russia.

Author

Nosov, Vladimir and Ivanova, Svetlana

Subjects
AGRICULTURAL productivity, SUGAR beets, WHEAT, PLANT reproduction, SUNFLOWERS
Abstract

The article examines the progress of agricultural products in Russia. It states that the improvement of agricultural products in the country such as wheat, sunflower, and sugar beet, has been observed since 1990s, whereby. Sugar beet has benefited the most because of the widespread adoption of modern product technologies. It also mentions moderate yield improvement in wheat while the sunflower crop management is trailing and needs improvement.
