Abstract : Systems for the industrial cultivation of wheat are being developed for and introduced in various regions of the country. Some 41 million hectares of land were used in the USSR in 1987 for the industrial cultivation of wheat. Such intensive cultivation involves a series of agricultural techniques that produce large, stable harvests. Although the GSSR is not known as a wheat growing region, some 180,000 hectares of wheat are grown here, consisting primarily of three varieties: Kavkaz, Bezostaya 1, and Deda, whose harvests reach 20-25 cwt/ha. The researchers here sought to study the effect of modern agricultural techniques on the development of a complex of winter wheat diseases in order to determine the feasibility of growing certain foreign varieties of wheat (Caribo, Fidel, Skaut, Armada, Avalon, and Mironovskaya 808) in the GSSR. Their studies, performed in Borzhomskiy Rayon, involved various aspects of intensive farming (tilling, fertilizer applica tion, top dressing, etc.) and included spraying the plants with preparations such as Bayloton and tilt. Artificial infection with fungal diseases was used to test the plants and the effectiveness of fungicides. The use of fungicides on the various varieties increased wheat production by an average of 20 cwt/ha. References 7: 2 Russian, 5 Western.
