Abstract:
Cabbage is one of the most important vegetable crops in the world for its resilience. Cabbage crops require soils with a pH between 6 and 7.5. If necessary, amendments are used to correct soil acidity. Organic and inorganic fertilizers provide nutrients available to cabbage plants for proper vegetative growth. It has been found that nitrates accumulate predominantly in the outer leaves rather than in the head. The method of obtaining the biostimulant has different effects on nitrate content. Thus, in most cases, biostimulants obtained through mechanical homogenization decreased the nitrate content in the leaves but increased the nitrate content in the head; biostimulants obtained using ultrasound had the opposite effect, namely increasing nitrate content in the leaves but decreasing it in the head. The results obtained regarding the influence of herbal biostimulants on the content of microelements and macroelements will be presented.
