Kozlyk T. Effect of the tillage methods and fertilization on the agrophisical soil properties, fibre flax yield and quality in the conditions of the Polissia

Subject of research - the transformation of agrophisical soil state indices at different tillage methods and fibre flax growth and development dynamics depending on the agrotechnical factors. The aim - the improvement of fibre flax growing technology components. The methods are field, analitical, computational and comparative, mathematical, statistical, economic- mathematical simulation. The autumn blade cultivation effeciency is established with the optimal fertilizer dose use in the agrophisical soil property improvement and fibre flax yield and quality increasing in the conditions of the Polissia, the pozitivity to use seeding machines with disk-shares for flax sowing is determined, the fibre flax growing technology is improved what secures the increase in qualitative fibre yield by 28-44%with cutting of productioncosts by 5.0-10.5%. Inculcation - the recommended growing technologies are introdused in the Novohrad-Volynsky district of Zhitomyr region during 2007-2008 over an area 315 ha. The branch of application is the agricultural production.
