THE EFFECTS OF DIFFERENT FOLIAR TREATMENTS ON THE SUNFLOWER CROP

Abstract

The use of foliar fertilizers and biostimulators can be an important tool for increasing the yielding capacity of the sunflower plants and their ability to support stress factors, especially in these times when climate change has become the biggest global challenge for agriculture and food production. Foliar fertilizers are very useful in meeting the plant's requirements for various macro and micronutrients, and foliar biostimulators are very useful in improving and stimulating plant life processes. Starting from this aspects, the purpose of this paper is to present the effect of different foliar treatments (foliar fertilizers and biostimulating products) on sunflower plants in the specific growing conditions of south-eastern Romania. In this sense, research was carried out in the specific growing conditions of the South-East of Romania in climatic conditions in the years 2022 and 2023. The experimental variants were represented by two foliar fertilizers (YaraVita Brassitrel Pro and Lebosol Nutrifos), and two biostimulating products (Seactiv Gold and Atonik). Seactiv Gold biostimulator stood out with the highest grain yield associated with the smallest plant height, but the highest number of leaves per plant.
