Influence of fertilizers on productivity of oil flax varieties Istok

To use the full potential of the new variety, taking into account its productivity and adaptability to the climatic conditions of the region, it is necessary to study the complex of agricultural techniques, primarily doses of mineral fertilizers. The results of the influence of fertilizers (1 - Control (without fertilizers), 2 - N15 P15 K15, 3 - N30 P30 K30, 4 - N60 P60 K60) on the productivity of oilseed flax were analyzed in Penza research Institute for the period 2015-2017. It is established that the variety is the Source with the introduction of nitrogen-phosphorus-potassium fertilizers in the dose of 60 kg D. V. the maximum seed productivity per hectare was 1.82 tons per hectare and the collection of oil and crude protein amounted to 709.7 and 436.7 kg/ha.The change in doses of mineral fertilizers did not have a significant impact on the oil and protein content in flax seeds and amounted to 43.47 - 43.89% and 24.27 - 30, 0%, respectively. The weight of 1000 seeds was in the range of 5.41-5.52 g. Application of nitrogen-phosphorus-potassium fertilizers norm 60 kg / ha provided an increase in the yield of flax straw by 26.7 % compared to the control.
