USE OF PEATY ELIXIR ON SPRING RAPE AND POTATO SOWINGS FOR IMPROVEMENT OF PRODUCTION FERTILITY AND QUALITY

Abstract

Our research target was to investigate how the Latvian-made humin substance for harvest and production quality can influence the seed-tuber pre-sowing treatment and the sprinkle of vegetative plants of spring rape and potatoes. Using the Peaty elixir under conditions of biologic farming f o r the pre-sowing treatment of spring rapeseeds provided a remarkable increase in the seed yield 0,19-0,31 t ha ‘. The crude intent within the seeds increased, on average, to 1,01-2,26%, and crude f a t to 1,57-1,88%. Treatment of the spring rape vegetative plants resulted the increase in the seed yield to 0,37 t ha ‘, increasing the crude fat content in the seeds to 1,45%>. The treatment of seed-tubers and vegetative potato plants provided a remarkable yield increase, and increased the starch content, decreasing nitrates in the production. Most effective the Peaty elixir, however, is when used together with mineral fertilizers.
