V raziskavi smo proučevali vpliv sistema pridelave na kakovost pridelka rastlin rukvice in mizune. Zanimalo nas je ali pride do razlik v vsebnosti nitrata, vitamina C in glukozinolatov v pridelku rukvice in mizune, glede na sistem pridelave. Poskus je potekal v letu 2021, v rastlinjaku na laboratorijskem polju BF UL, kot dvofaktorski poskus, v split-plot zasnovi, s 4 ponovitvami. Glavno parcelo je predstavljal sistem pridelave (gola tla, folija in bazen), na podparcelah sta bili rukvica in mizuna. Pred rezjo smo izmerili višino rastlin in porezane rastline stehtali. V laboratoriju smo po vsakem pobiranju pripravili vzorce za kemične analize. Ob rezi smo jemali tudi talne vzorce za spremljanje dinamike vsebnosti nitrata v tleh. Redno smo merili tudi osnovne parametre v hranilni raztopini. Največji pridelek rukvice je bil na foliji (2456,7 g/m2), sledi pridelek na golih tleh (966,7 g/m2) in najmanjši na bazenu (414,4 g/m2). Največji pridelek mizune (9076,4 g/m2) je bil na bazenu, sledi pridelek na foliji (6862,5 g/m2), najmanjši pa na golih tleh (4744,2 g/m2). Pri rukvici je delež suhe snovi večji pri pridelavi na bazenu (8,4 %) glede na pridelavo v tleh (7,1 %). Nasprotno smo ugotovili za mizuno. Vsebnost nitrata je večja v pridelku rukvice (864,7 mg/kg sveže mase) in mizune (1603,4 mg/kg sveže mase) z bazena glede na talno pridelavo. Vsebnost glukozinolatov pri rukvici je bila največja na golih tleh (0,5 mg/g suhe mase) in najmanjša na zastrtih tleh (0,3 mg/g suhe mase). Pri mizuni je bila vsebnost glukozinolatov večja pri talni pridelavi (4,7 mg/g suhe mase) glede na bazenu (3,7 mg/g suhe mase). Vsebnost vitamina C je bila večja v rastlinah rukvice pridelane na zastrtih tleh (597 mg/kg sveže mase), najmanjša pa na golih tleh (259 mg/kg sveže mase ). Pri mizuni, je bila povprečna vsebnost vitamina C največja v vzorcih z bazena (1208 mg/kg sveže mase), najmanjša pa na golih tleh (651 mg/kg sveže mase).

• Title: The yield quality of rocket (Eruca sativa Mill.) and Brassica rapa Group Mizuna grown in hydroponics and in soil

Abstract

In this study, the influence of the cultivation system on the yield quality of rocket and mizuna was evaluated. We were interested if there are differences in the content of nitrate, vitamin C and glucosinolates in the yield of rocket and mizuna, depending on the cultivation system. We set up the experiment in 2021, in a greenhouse on the BF UL laboratory field. We designed a two-factor experiment in a split-plot design, with 4 replications. The main plot was represented by the cultivation system (bare soil, foil and pool), rocket and mizuna were randomly distributed on the subplots. Before cutting we measured the height of the plants and weighed. In the laboratory samples were prepared for chemical analysis after each collection. We also took soil samples to monitor the dynamics of the nitrate content in the soil. We regularly measured the basic parameters in the nutrient solution. The highest yield of rocket was on foil (2456,7 g/m2), followed by the yield on bare soil (966,7 g/m2) and the smallest on the pool (414,4 g/m2). The highest yield of 9076,4 g/m2 of mizuna was on the pool, followed by the yield on foil (6862,5 g/m2) and the lowest was the yield on bare soil (4744,2 g/m2). The content of dry matter in rocket was higher in pool cultivation (8.4 %) than in soil cultivation (7.1 %). We found the opposite for mizuna. Nitrate content was higher in the hydroponically grown rocket (864.7 mg/kg FW) and mizuna (1603.4 mg/kg FW) compared to soil cultivation. The content of glucosinolates in rocket was the highest on bare soil (0.5 mg/g DW) and the lowest on covered soil (0.3 mg/g DW). In mizuna the content of glucosinolates was higher in soil (4.7 mg/g DW) compared to hydroponic cultivation (3.7 mg/g DW). The content of vitamin C was higher in rocket plants grown on covered soil (597 mg/kg FW) and the lowest on bare soil (259 mg/kg FW). In mizuna, the average vitamin C content was the highest in the pool samples (1208 mg/kg FW) and the lowest on the bare ground (651 mg/kg FW).
