## Abstract

The development of innovative technologies aimed at increasing agricultural crop yields through the use of growth regulators that incorporate various biologically active chemical moieties is a key focus in modern global agroscience. In this context, novel water-soluble silicon-organic compounds derived from carbamate (I) and oxamate (II) have been synthesised by the introduction of an organo-silicone fragment into these biologically active molecules. The compounds are O-isopropyl-N-(2-trimethylsilyloxyethyl)carbamate (III) and O-isopropyl-N-(2-trimethylsilyloxyethyl)oxamate (IV). It has been found that the 1 × 10−5 M water solutions of the compounds I–IV exhibited growth-regulating activity on the seeds of spring common wheat (Triticum aestivum L.). Laboratory studies demonstrated that the new silicon-containing compounds III and IV had a positive influence on the following: the germination potential, the seed germination, the length of roots, and the growth and development of shoots. Field tests revealed that spring wheat treatment with the compounds III and IV yielded an augmentation in spike length, an elevated quantity of grains per spike, and a grain mass per spike in comparison to the control. The application of compounds I–IV resulted in a significant enhancement in spring wheat yield.
