The aim of the present study is to investigate the effects of biological soil improvers - liquid organic fertilizers obtained by different methods - through nanotechnology and through hydrolysis of plant meals - and to determine the optimal doses of these preparations for maximizing grain yields from new genotypes of common winter wheat (Triticum aestivum) developed by the method of combinatorial breeding. The experimental plot is established in the biological experimental field of the Institute of Plant Genetic Resources in Sadovo (Bulgaria), with three replications of seven fertilization
treatments, over two consecutive growing seasons: 2023/2024 and 2024/2025. In the older hybrid wheat selections, grain yields are more strongly influenced by the type and quantity of applied fertilizers, as well as by agrometeorological conditions. The highest and most stable yields are obtained from the newest breeding lines. The effect of the fertilizer containing phytohormones depends primarily on agrometeorological conditions; when sufficient moisture is available, the active ingredients of the fertilizer are effectively absorbed, and increasing the dose leads to higher grain production. The effect of the nanofertilizer liquid humus on yields is weaker, limited at a level of 1000 ml/da, and the results of its use depend on the sink capacity of the genotype.
