Abstract

The article presents the results of studies on the influence of biological regulators of growth and sowing time on leaf area formation, photosynthetic potential, and the net productivity of photosynthesis of winter barley plants, which will increase the variety productivity of the crop and reduce the anthropogenic load on the soil and plant.

Research was conducted in the conditions of irrigation with a typically winter variety Akademichnyi and two-handed the Dev’iatyi val at sowing 1 and on October, 20 and treatment of seed and plants by the regulators of growth of Humifild Forte brics, MIR and PROLIS. "Methods of the field and laboratory researches on the irrigated earths" of Institute for Irrigated Agriculture (IIA) of NAAS 2014 to the year. Soil of the experimental field is a durk-chestnut, heavily loamy, salt-marsh with content of humus – 2,3%, by a closeness – 1,37 g/cm², by fading humidity – 9,1%, by the least moisture-capacity – 20,3%. Before sowing there was 15,1–24,2 mg in the arable layer of NO3, Р2О5 – 53,8–83,9, К2О – 245–281 mg on 1 kg of soil.

The use of growth regulators contributed to a growth of 7.6-25.3% of the area of the leaf surface, with variety the Dev’iatyi val on the average created it by 2,3-3,7 ths. m2/ha more than variety  Akademichnyi, which is due to the biological properties of the two-handed. The maximum area of the leaf surface is 68,9 ths. m2/ha Dev’iatyi val was formed during the processing of seeds with the MIR preparation, and a variety is Akademichnyi 65,8 ths. m2/ha - in the treatment of plants with the drug Humifild.

Use of regulators of growth on seed and plants at sowing 1 and on October, 20 increased the photosynthetic of variety  Akademichnyi accordingly on 0,22-0,30 and 0,15-0,25 million m2/days/ha, and variety the Dev’iatyi val - on 0,26-0,30 and 0,13-0,2 million m2/days/ha. The growth of pure productivity of photosynthesis on a variety is Akademichnyi  at sowing on October 1 and is with growth regulators was 0,4-5,2 g/m2 per day, when sown on October 20 - at 1,7-3,4 g/m2 per day, and on the variety of the Dev’iatyi val - by 1,0-2,5 and 0,7-1,7 g/m2 per day, respectively.

Maximal productivity of 7,19 t/ha a variety of the Dev’iatyi val was provided at seeding on October 1 and seed treatment with MIR, and the variety Akademichnyi 7,05 t/ha - the same term of sowing and treatment of seed of Humifild Forte brics.

Researches testify to positive influence of regulators of height the MIR and Humifild Forte brics on photosynthetic activity of plants and productivity of winter barley, therefore their application will be effective in technology of growing of culture in the conditions of irrigation.
