Abstract

The article describes the results of various pesticides using and pre-sowing application of nitrogen fertilizers for the planned yield for the zoned variety of soft spring wheat «Novosibirskaya 31» in the forest-steppe of the Krasnoyarsk territory. It was found that the number of plants surviving for harvesting and productive tillering had the best reaction to the using of fertilizers and pesticides from the elements of the crop structure in spring wheat. The maximum average yield increase was observed when wheat was sown on the fertilized background using a full range of pesticides, the minimum – on the fallow.
