Photosynthetic activity of plants and productivity of grain of winter barley (hordeum vulgare l.) in dependence on variety, terms of sowing and regulators of height
Journal Title: Біоресурси і природокористування [Biological Resources and Nature Management] - Year 2019, Vol 11, Issue 1
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. 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.
