It is known that the application of organic substances has effects to stimulate the development of plants. The paper presents the effect of two plant biostimulants (FERT - H and FERT - A) with organic matter of vegetable origin (protein hydrolyzate, respectively seaweed extract) on quality and production indicators for wheat, sunflower and soybean crops. The plant biostimulants were tested for three years by foliar application both in the experimental field in a wide range of crops, obtaining statistically significant and very significant yields compared to the unfertilized control. The obtained yields ranged between 50-60% for wheat, 8-9% for sunflower and 24-38% for soybean. Although there were differences in production between the two biostimulators, these were not significant. The plant biostimulants with natural organic matter (algae and soy hydrolysate) that were used can influence crop nutrition leading to increased product quality.
