Economic assessment of application of mineral fertilizers and bacterial preparations under oil flax in the conditions Rostov region

The results of three-year researches on application of fertilizers and bacterial preparations for the yield and quality of oil flax in the conditions of southern black soil of Rostov region. A significant effect on the seed yield of flax was provided by the use of mineral fertilizers, the yield increase amounted to 0,38-0,39 t/he in NDS experience of 0.14 t/he. Application of bacterial preparations in pure form conceded on action on productivity of plants to mineral fertilizers. The maximum efficiency among the bacterial preparations showed Agrofuel, which will provide the increase of seed yield of 0.23 t/he. The use of mineral fertilizers had a significant impact on the quality of flax seeds – an increase in the oil content of flax seeds in an average of 3 years amounted to 1.7-2.3, and the collection of oil 191 kg/ha or 45.6%. The use of mineral fertilizers had a significant impact on the quality of flax seeds – an increase in the oil content of flax seeds in an average of 3 years amounted to 1.7-2.3, and the collection of oil 191 kg/he or 45.6%. High profitability and profitability ensured the use of mineral fertilizers at a dose of N30P30 for presowing cultivation. The maximum economic efficiency in the experiment showed bacterial preparation Agrofil.
