Due to this, when feeding tomatoes with an infusion of onion peel, the growth rate of seedlings increases, their root system becomes stronger, and the stage of fruiting begins more quickly.
Nicotinic acid contained in onions and its surface scales promotes the development of the root system of tomatoes, even on unfavorable clay soils.
