20.500.12556/DKUM-70607 Pridelek in kakovost dveh sort solate v odvisnosti od pridelovalnega sistema Yield and quality of two lettuce varieties in different production systems Vedno več potrošnikov dandanes zanima kakovost zelenjave in njena povezava s tehniko pridelave. Na osnovi različnih pridelovalnih sistemov naj bi imela prednost zelenjava, pridelana na ekološki (EKO) ali biodinamični (BD) način, pred zelenjavo, ki je pridelana na integrirani (IP) ali konvencionalni (KONV) način. Poljski poskus je bil izveden v letu 2016 na trajnostnem poskusnem polju Univerzitetnega kmetijskega centra Pohorski dvor, kjer smo preučevali pridelek in kakovost (vsebnost nitratov, C-vitamina in sladkorjev) dveh sort solate ('Comice' in Leda') v različnih pridelovalnih sistemih (ekološki, biodinamični, konvencionalni, integrirani) ter v kontrolnem obravnavanju (K). Sorta 'Comice' ima statistično značilno višji skupni (57 t/ha) in tržni pridelek (45 t/ha) v primerjavi s sorto 'Leda' (41 t/ha, 33 t/ha). Sorta 'Comice' je statistično značilno boljša v vseh preučevanih morfoloških parametrih. Pridelovalni sistem ima statistično značilen vpliv na obseg, tržno in skupno maso rozet. Največji obseg ima solata v BD (58,8 cm), najmanjši pa v EKO (52,4 cm). Pri tržni in skupni masi je največjo maso dosegla solata v BD (390 g, 524 g), najmanjšo pa v EKO (300 g, 358 g). Pridelovalni sistem vpliva na vsebnost nitratov, askorbinske kisline ter na sladkorje z izjemo saharoze. Največ nitratov ima IP (295 mg/kg), najmanj pa K (130 mg/kg). Višje vrednosti vsebnosti askorbinske kisline in sladkorjev imata IP in KONV obravnavanje, nižje pa BD in EKO. Na osnovi rezultatov sklepamo, da lahko v EKO in BD pridelavi dosežemo skoraj primerljive rezultate kot pri KONV in IP. Sorta 'Comice' je boljša v primerjavi s sorto 'Leda' v večini preučevanih parametrov. Vzorci iz EKO in BD pridelovalnega sistema vsebujejo nižjo vsebnost nitratov, medtem ko za ostale notranje parametre prednosti teh dveh pridelovalnih sistemov ne moremo popolnoma potrditi. More and more consumers nowadays are interested in the quality of vegetables and their connection to the production technique. Based on the different production systems, vegetable grown on organic (ECO) or a biodynamic (BD) method should be given priority to vegetables grown on an integrated (IP) or conventional (CONV) mode. The field trial was carried in 2016 on a sustainable experimental field of the University Agriclulture center Pohorski dvor, where we studied the yield and quality (nitrate, C-vitamin and sugars content) of two varieties of lettuce ('Comice' and 'Leda') in various production systems (organic, biodynamic, conventional, integrated) and in control treatment (C). The 'Comice' variety statistically significant affects the higher total (57 t/ha) and market yield (45 t/ha) compared to the 'Leda' variety (41 t/ha, 33 t/ha). The 'Comice' variety is statistically significantly better in all studied morphological parameters. The production system has a statistically significant impact on the volume, marketable and total mass of the rosette. The largest volume has a salad in BD (58.8 cm) and the lowest in ECO (52.4 cm). The largest marketable and total mass was reached by salad in BD (390 g, 524 g), the lowest in ECO (300 g, 358 g). The production system affects the content of nitrates, ascorbic acid and sugars, with the exception of sucrose. Most nitrates have IP (295 mg/kg), the least C (130 mg/kg). Higher values of ascorbic acid and sugars content have IP and CONV treatment and lower BD and ECO. Based on the results, we can conclude that in ECO and BD production we achieve almost comparable results than in CONV and IP. In most od the studied parameters the 'Comice' variety is better compared to the variety 'Leda'. Samples from the ECO and BD production systems contain lower nitrate content, while for the other internal parameters the advantages of two production systems cannot be fully confirmed. solata pridelovalni sistem pridelek morfološke lastnosti kakovost lettuce production systems yield morphological properties quality true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2018-05-30 11:56:16 2018-06-11 14:49:45 2022-08-01 19:33:51 2019-07-11 18:13:17 2018 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:OWTGE1CH VS_Novak_Barbara_2018.pdf VS_Novak_Barbara_2018.pdf 1 AD5A8D39D9637A37E14A2A245ED2AE77 fd9ea114b9f80c683d3c148b24c9cdce7f872b5a9c54dc9b7be3e25c1396e24d fcecde7b-7c0f-11eb-bb7a-00155d0001ca 20.500.12556/dkum/09e64d0a-c342-4c9e-86a6-f9158830d07e https://dk.um.si/Dokument.php?lang=slv&id=125151 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
