The effect of different doses of different biostimulants on the yield of oily sunflower

Abstract

Biologically active substances (BASs), including plant phytohormones-regulators of plant growth and development, are becoming increasingly important in agriculture activities. Their use allows to better realize the genetic potential of crops, increase the resistance of plants to stress factors of biotic and abiotic nature, and as a result increase yields and improve quality. In this research, it was aimed at researching effect of different doses of different biostimulants on the yield of oily sunflower. In the research experiment, “Methods of field experiments” developed by B. Dospekhov was used. According to the results, it was found that microbio-fertilizers, biostimulants, immunostimulants had positive effect on the growth, development and seed formation of the local Dilbar variety of sunflower, the weight and yield of 1000 seeds. When biodux biostimulator was applied to the 1.0 ml/t seed variant, the height of sunflower stem was 28.5 cm higher than the control and 7.1 cm higher than the “UzGUMI” standard. Furthermore, when the MERS microbiota fertilizer was used in the 2.0 ml/ton variant, the stem height was 25.5 cm higher, and it was 4.1 cm higher than the UzGUMI standard. The 1000 seed weight was found to be heavier than the other biostimulants used in the experiment, especially in the variant using MERS microbiota.

Influencia de bioestimulantes y aguas contaminadas en la morfología del girasol ornamental Helianthus annuus L.

“…Además, el agua de canal mostró un efecto negativo en el crecimiento de las plantas, ya que presentó la media más baja. Estos hallazgos resaltan la importancia de seleccionar adecuadamente los bioestimulantes y el tipo de agua utilizados en la producción de girasoles ornamentales, ya que pueden tener un impacto significativo en su morfología y crecimiento (Yuldasheva & Karabayeva, 2023). Los resultados revelan que hubo diferencias significativas en el número de hojas entre los diferentes tratamientos evaluados (Figura 3).…”
