Influence of Complex Microfertilizer "Phytohumate" on the Yield and Quality of Lobg-stalked Flox
The use of huminous fertilizers is an effective method for stimulating the growth and development of plants, providing the resistance to diseases and unfavourable climatic factors. Here are the results of the research on studying the affect of the water-soluable fertilizer «Phytohumate» on the yield of flax straw, seeds and the quality of fibre of the long-stalked flax of the sort Pamyat Krepkova in Kostroma region. The soil of the experimental plot was dern-podzolic, average clay loam with the content of humus 1,83% pH - 6,0, P<sub>2</sub>O<sub>5</sub> - 120 mg/kg of the soil, K<sub>2</sub>O - 39 mg/kg of the soil. Sowing during the year of research was done on May 19. The area of the experiment was 180 m<sup>2</sup>, it was repeated 3 times, the location of plots was systematic, the square of the plot under analysis was 20m<sup>2</sup>. The experiments were carried out on the phone - application of complex mineral fertilizer in the doze N<sub>26</sub>P<sub>38</sub>K<sub>38</sub> kg/ha before sowing. The rate of sowing was 20 mln of germinating seeds per 1 ha, the weight norm of sowing was 100 kg/ha. The evaluation of the quality of the retted straw of the long-stalked flax was done according to GOST P 53143-2008 «Flax retted straw», GOST 24383-89 «Flax retted straw». Requirements for procurement (08.06.2007) the definition of the numbers of the swingled flax was done according to GOST 10330-76 «Swingled Flax». Technical conditions (according to change № 4). Statistical working out of the yield data was done by the method of disperse analysis and by using the computer program AGROS-2.02. The positive affect of «Phytohumate» of the level of biological yield of flax straw and seeds (up to 5,63 and 1,0 t/ha), on the yield of fibre and its quality is marked. On the base of the given research the perceptiveness of the use of the mircrofertilizer «Phytohumate» on the long-stalked flax can be noted. Water-spraying at the period of the «Yelochka» phase increases the efficiency of this method.
