BOOK OF PROCEEDINGS eng Use of controlled-release mineral fertilizer in production of pot grown Levisticum officinale L. application/pdf 1139294 bytes 2022 Controlled-release mineral fertilizers (CRMF) have been developed and designed in order to improve the efficiency of fertilizers. Better efficiency in use of CRMF compared to conventional mineral fertilizers is mostly reflected in: decrease of chemical immobilization in soils which blocks uptake of nutrients by plants; lowering a fertilizer application frequency and rinsing out of nutrients in soil which consequently reduces a damaging effect on the environment. The aim of this study was to test if an application of CRMF will result in the improvement in development of aboveground biomass of pot grown lovage. The seedlings of lovage were produced in laboratory conditions, in containers placed inside a polyethylene tent (Grow Box), under the artificial lighting. With the development of the first true leaves, seedlings were transplanted into pots and submitted to treatments: CRMF- Osmocot Exact in formulation (NPK 15:9:12 +2MgO+TE), in which is gave 0,45 g N, 0,27 g P2O5 and 0,36 g K2O per L of substrate (pot) and without adding fertilizer (control). After 60 days of growth in the non-heated greenhouse, for 30 plants of each treatment, the absolute dry mass of aboveground biomass (g/plant), number of branches and plant height (cm), were recorded. The highest yield of the aboveground biomass and the highest number of branches were obtained in CRMF (5.17± 0.72g and 6 to 13 branches/plant) compared to control (1.93±0.29g and 5 to 9 branches/plant), respectively. Regarding the plant height, better effect was achieved by CRMF (41.31± 3.43 cm) compared to control (29.37± 2.40 cm). Obtained results have shown positive effects of CRMF on development of aboveground biomass of pot grown lovage. https://unilib.phaidrabg.rs/o:3204 info:eu-repo/semantics/conferenceProceedings Mrđan, Snežana Radanović, Dragoja Filipović, Vladimir Gordanić, Stefan Prijić, Željana Batinić, Petar Dragumilo, Ana Marković, Tatjana lovage, medicinal plant, controlled-release fertilizer All rights reserved
