Application of plant growth regulators for vegetables: cucumber, tomatoes, cabbage, bell pepper, carrot, onion, eggplants, potato
Application of plant growth regulators for cucumber. 
Presowing cucumber seed soaking or incrustation with Ivin, Emistim C or Biolan promotes increase of germination energy of seeds by 5-9%. Growth and development of plants in an initial stage is accelerated: growth of germinative root and side shoots strengthens, leaf surface, chlorophyll content in leaves increase, physiological processes are stimulated, the quantity of female flowers and buttons increases. Fruit ripening is accelerated by 2-5 days.
Application of plant growth regulators for tomatoes. 
Seed treatment of tomatoes with growth regulators Ivin, Biolan or Emistim C promotes increase of seed germination energy by 5-8 %, accelerates seedling emergence and formation of the developed root system. Transplant seedlings of tomatoes have brighter green colouring of leaves at the expense of activation of chlorophyll synthesi and better take roots.
Application of plant growth regulators for cabbage.
Presowing cabbage seed soaking in solution of Ivin, Biolan or Emistim C, seed incrustation with regulator jointly with protectants promotes increase of germination by 5-7 %, stimulates growth of sprouts, enhances plant resistance to diseases, improves fruit quality: content of sugar and vitamin C increases, yield is enhanced by 15-30 % (3.0-5.0 t/ha).
Application of plant growth regulators for bell pepper.
Presowing seed treatment and spraying of crops with plant growth regulators promotes increase of field germination by 10-25 %, the best survival ability of plants, reduction of diseases. Sprout quality improves: it has more developed root system and more intensive colouring of leaves.
Application of plant growth regulators for carrot.
Presowing seed treatment with plant growth regulators enhances field germination by 10-13 %, accelerates seedling emergence, stimulates plant growth and development, increases leaf surface that promotes formation of bigger root crops. Growth regulators accelerate ripening, increase standard root crops yield, enhance yield by 3.5-5.0 t/ha (19-27 %).
Application of plant growth regulators for onion.
Seed soaking and spraying of onion crops with plant growth regulators enhances field germination, promotes seedling emergence, enhances planting onion yield by 25-49 %, bulb onion - by 30-40 %, high-quality seeds yield - by 25-30 %.
Application of Emistim C or Biolan for seed soaking of cultivars "Skvyrska", "Strygunovska", "Nosovska" in farms of the Kyiv region promotes extra yield by 5.0-6.0 t/ha (25-30 %). In the case of second plant spraying in the stage of 3-5 leaves the increase of planting onion yield is 6.3-7.3 t/ha (30-35 %). After spraying of bulb crops in the stage of 3-5 leaves the extra yield is 5.9-7.8 t/ha (30-40 %). Spraying od seed crops in the scape forming stage enhances seed yield by 240-300 kg/ha (40-45 %)
Application of plant growth regulators for eggplant.
Presowing seed soaking in solution of Ivin promotes increase of seed germination, best development of plants. Biostimulant use allows to cultivate high-quality transplant seedlings that better take roots. Flowering and fruit ripening is accelerated by 2-5 days, their vendibility improves, the content of dry substances increases.
Application of plant growth regulators for potato.
The research has shown that along with conventional agronomic practice in the intensive technologies of potato cultivation, one of powerful reserves of yield increase is application of plant growth regulators. The technology consists of both pre-planting tuber processing, and spraying of plants.
Areas of Application

Leave them out for longer periods of time until the night-time temperatures are above
50 degrees. However, it is difficult for people to perceive that there is a need for these tents.
I hope to provide something back and help others like you helped me.
I'm trying to get my blog to rank for some targeted keywords but I'm not
seeing very good success. If you know of any please share.
Kudos!
