Effect of Biostimulants on Wheat yield and Grain Quality

Wheat (Triticum aestivum L.) is one of the most important agricultural crops worldwide, serving as both a staple food and a primary source of income for millions. Its grain quality is influenced by genetic, environmental, and management related factors, with test weight (hectoliter weight) being a key parameter for commercial classification. This study aimed to evaluate the effect of the biostimulant Penergetic, applied in different forms and dosages, on wheat yield and grain quality. The field experiment was conducted in Santa Maria, Rio Grande do Sul, Brazil, using the ORS Soberano cultivar in a randomized block design with six treatments and eight replications. Treatments involving the combined application of the biostimulant in both liquid and solid formulations resulted in improved foliar health, indicating reduced biotic stress and enhanced biological balance in the soil. Consequently, significant increases in both grain yield and quality were observed, particularly in the treatment with the highest dosage, which achieved a test weight exceeding 80 kg.hL⁻¹. The biostimulant effect of the commercial Penergetic product contributed to enhanced enzyme activity in the soil, improved plant nutrient uptake, better foliar health, and overall vegetative development. The findings indicate that biostimulants based on Penergetic Technology significantly increase wheat yield and grain quality, with the most pronounced benefits observed under the combined application of both liquid and solid formulations at the highest tested dosage. These results emphasise the essential role of soil biological fertility in determining wheat crop performance.
