Study of the effectiveness of combined electrophysical influence on tomato seeds

Abstract

The paper presents the results of experimental studies on the combined pre-sowing treatment of the tomato seed material of a tomato variety “Malva”, which consisted of exposure to visible radiation in the range from 460 to 625 nm and an alternating magnetic field with induction from 6.5 to 65 mTl. Experimental studies were conducted at all stages of plant development: from pre-sowing seed treatment to the final products (tomatoes). As a result of the experimental studies, we revealed that the best results obtained about the dry matter content in tomato seedlings and about the yield on the root of the final products (tomatoes) are achieved at presowing seed treatment with two influencing factors. The first is optical radiation with a wavelength of 460 nm and treatment time of 60 s. The second is magnetic field with an induction of 39 mTl and treatment time of 30 s. After such combined treatment, the seeds were cured for 120 hours before sowing. As a result, we experimentally recorded that the dry matter content in tomato seedlings increased by 25.41%, and the tomato yield increased by 38.00%, compared to the control variant. This allows us to speak about such seed treatment before sowing as an effective agro-technological method, which can be recommended for use in vegetable growing.
