TECHNOLOGY OF POTATO WEED MANAGEMENT UNDER CONDITIONS OF LOW INPUT
Original language description
Between years 2011 and 2013 field trials were established with potatoes involving various variants of herbicide applications using recommended rates and 50 % reduced rates. The research was done in 3 replications using de-stoning technology and the early ware potato variety Dali was involved. The aim was to determine, whether low input system could be applied in de-stoning technology for potato growing and whether recommended rate of herbicide could be 50 % reduced while maintaining required level of weed control effect and the same yielding level.. The trials show that 50 % reduction of herbicide rate did not have an effect on potato yield. Weed control efficiency, measured toward the end of vegetation, was not reduced in the first trial year due to variants with reduced herbicide rate; in following two trial years the efficiency was 8-12 % reduced. However, this reduction was not expressed in potato yields. The reason is that efficiency reduction did not reach threshold of harmfulness of weed species. Significant differences in potato yields were not found between variants, except for the variant without treatment. From research standpoint reduced herbicide application could be recommended.
