Biostimulants and soil conditioners provide improved soil conditions for growth and development of plants and also play a significant role in modern vegetables production. Plants treated with biostimulants achieve higher resistance to unfavourable abiotic and biotic stresses. Soil conditioners are substances with main purpose of improving the chemical, physical and biological characteristics of the soil. Due to the increasing availability of biostimulants and soil conditioners in the market, it is necessary to research their influence on morphological traits, yield and nutritional value of different vegetable species. Therefore, during the spring-summer growing period of 2016 research was conducted on a family farm in Zagreb (Žitnjak). The aim of the research was to determine the effect of biostimulant 'Bio- algeen S92', soil conditioner 'Azomite' and their combinations on the mineral content and yield of rocket (Eruca sativa Mill.) compared to the control. Rocket was grown from seedlings on polyethylene mulch in an unheated greenhouse. The morphological properties (mass, height, number of leaves), leaf mass per planting place and yield were determined. Mineral content of rocket was analysed after first harvest (40 days after planting). The highest yield in the first and second harvest, as well as the total yield of the rocket (3.96 kg m-2), was determined in rocket treated with the combination of 'Azomite' and 'Bio-algeen S92'. Among the tested treatments, statistically justified differences in the amount of all minerals except for phosphorus were determined. The highest amount of iron, zinc, and manganese was recorded by the application of 'Azomite' + 'Bio-algeen S92'. On the basis of the obtained results, the combination of 'Azomite' and 'Bio-algeen S92' can be recommended for growing rocket due to a positive influence on morphological properties and mineral content of leaves.
