Description
Summary:Biological activity and organic matter content of soil can be improved by the application of organic fertilizers. As the EU legislation restricts the time and doses of N added with stable manure, the need and possibility have arisen to apply industrially processed organic fertilizers. For this reason, investigations were carried out at the trial field in Zagreb with the aim to determine the effects of applying pelleted organic-biological fertilizer “Bio Univerzal” upon broccoli and lettuce yield components. In the spring-summer period, all broccoli cultivars grown on plots on which organic fertilizer was applied produced higher mass and yield of marketable top inflorescences compared to plots fertilized with mineral fertilizer only. Depending on the broccoli cultivar, organic fertilizer application led to increase of marketable top inflorescence mass by 3 to 12%, resulting in marketable yield increase from 3 to 22%. Organic fertilizer application in the summer-autumn lettuce growing period resulted in a 7 to 12% increase of marketable rosette mass and yield of all four cultivars studied.
