ENERGY-ECONOMIC EFFICIENCY OF APPLICATION OF STIMULATOR OF ALBIT GROWTH ON LINA-DELLOUNTS SOWINGS

On the basis of field studies and mathematical calculations, the positive effect of the growth promoter of the biological origin of albite on the energy-economic efficiency in the cultivation of flaxdolgunts has been established. Field studies to determine the effect of the albite growth stimulator on the productivity of flax and dolgunts were conducted in 2005-2007 in the experimental farm "Grozynskoe" of the Institute of Agricultural Policy of Polesie NAAN. The research was carried out on a Lyra leaf blade. Albit was used, as for pre-sowing treatment with norms of 50, 60, 70 ml/t seeds and in addition extra-root nutrition. In pure form and against the background of pesticides (Lionok, Panther, Fundazol). Spraying was carried out in the phase of "lightweight" with a norm of 40 ml/ha. The use of pre-sowing seed treatment with albumin preparation at a dose of 50-70 ml/ton and additional extra root nutrition in a dose of 40 ml/ha contributed to a straw yield of 0.61-0.98 t/ha compared to absolute control and a 0.52-0.89 t/ha relative to the variant N₃₀P₆₀K₉₀ (control) and 0.09-0.46 t/ha compared to the herbicide fungicidal background. In these cases, seed yield growth was 39-64% relative to absolute control and by 31-54% compared to the control variant (N₃₀P₆₀K₉₀) and 21-42% relative to the background. These methods of application of the preparation allow obtaining an additional increase in the yield of both straw and seeds and accumulated in it 27392-37896 MJ of energy, with a coefficient of energy efficiency in the range of 2.4-2.9. According to economic calculations, effective variants have been established: treatment of seeds with an albumin growth stimulator in doses of 60-70 ml/t seeds, followed by extracorporeal feeding in a dose of 40 ml/ha in a tank mixture with pesticides. The conditionally net profit in these variants was 1004.3-1124.7 UAH/ha, and the level of profitability was 190.1%-20.79%, respectively
