Abstract

The effect of preparations containing silicon: seliplant nanosilicon, Bona Forte biostimulator and sodium silicate on growth, development and yield was studied on hybrids of cucumber Pierre F1 and tomato Merlis F1. Studies have shown that when tomatoes are fed under the root, the product matures early and yields increase by 6.5-8.0 kg/ m², and this indicator is due to an increase in the number of fruits (by 10-12%), and the average fruit weight increased by 18-23%. As a result of the use of silicon-containing fertilizers in the cultivation of cucumbers, an increase in the area of assimilation, an increase in the number and weight of the formed fruits was observed. Productivity and product quality increase, as well as the amount of dry substance increases and the amount of nitrates in products decreases, that is, it decreases from 382 mg/kg to 181-230 mg/kg. The reason for the maximum increase in cucumber yield by 5.3-6.5 kg/m² was observed as a result of the use of bio stimulants containing seliplant and silicon.
