Application of ˈRhyzo BZˈ fertilizer microparticles during pepper cultivation in urban gardens

Food production is of symbolic and practical importance in sustainable cities. Vegetable gardening in public spaces and community gardens is one of the most important topics to investigate as a possibility of food production in modern cities. The aim of this research is to explore how the application of ˈRhyzo BZˈ fertilizer microparticles could increase the stability and viability of biological and chemical agents for a longer time period with the time-release mechanism during pepper (Capsicum annuum var. macrocarpum L.) cultivation in urban gardens. The cultivation environment was monitored by an agrometeorological station continuously logging the following parameters: air temperature, humidity and pressure, soil temperature and humidity, precipitation, wind speed and direction, and leaf wetness. The optimization process of ˈRhyzo BZˈ fertilizer encapsulation in the biopolymers microcapsules was performed under optimal conditions of concentrations of sodium alginate (2 %) and calcium nitrate(1.5%), for optimal microcapsules enriched production. The experimental urban garden was set up in Zagreb (Faculty of Electrical Engineering and Computing). Planting of pepper seedlings (cultivar ˈSlonovo uhoˈ) was done on May 26, 2021. Harvest of pepper fruits lasted from July 13 to October 12, 2021. After harvest, in samples of pepper fruits some chemical properties were determined (polyphenols and carotenoids. The obtained results showed that the application of ˈRhyzo BZˈ fertilizer microparticles increased the morphological and chemical properties of the fruits cultivated in urban gardens.
