ANALYSIS OF PRODUCTIVITY OF SPRING WHEAT VARIETIES IN PRODUCTION SOWING OF THE "NORTH-KAZAKHSTAN AGRICULTURAL EXPERIMENTAL STATION" LLP

Abstract

In the structure of sown areas of "North-Kazakhstan Agricultural Experimental Station" LLP in separate fields for the same predecessor in spring wheat varieties, the gap between the record and minimum yield can reach very significant sizes. In the spring soft wheat variety Omskaya 35, the gap between the maximum yield and the minimum reached 15.4 kg/ha, which is 60% of the total
record crop. In the Damsinka Amber durum wheat variety, this indicator was at the level of 19.4 c / ha, which is 65% of the record crop. High yield variability in the structure of sown areas creates unfavorable conditions for obtaining additional grain harvests in the production sowings of "North-Kazakhstan Agricultural Experimental Station" LLP. For example, in 2016, the Omskaya 35 spring soft
wheat variety on the sown area of 890 hectares could, in addition to the total gross grain harvest, produce another 81.9 tons. In the climatic conditions of 2017, the
additional gross grain harvest of this variety on an area of 330 hectares could be 13.9 tons. In 2016, the gross grain yield of the spring durum wheat variety Damsinskaya Amber could have amounted to 198.0 tons of grain in addition to the total harvest of 483 ha. In 2018, this indicator on the total sown area of 234 hectares could amount to 35.3 tons of grain. In this regard, the approximation in the production crops of "North Kazakhstan Agricultural Experimental Station"
LLP of the level of the minimum yield of honeycomb spring wheat to the maximum would significantly increase grain harvests.
