About efficiency of short-cut period of preplant treatment of corn seed by growth regulator in field conditions

The authors studied an influence of the duration of treatment of the seeds of maize and wheat by solutions of kinetin and indolylacetic acid on their field germination, stem height, area of leaves surface, net productivity of photosynthesis and crop capacity and also they estimated economical and energy efficiency of short-cut periods of treatment by growth regulator. It was shown, that more favorable effect result in brief treatment (8-16 hours) of seed by growth regulator solutions. The prolonged treatment reduces the economical and energy efficiency of used substances.
