20.500.12556/DKUM-63949 Vpliv načina pridelave na pridelek in kakovost paradižnika Impact of production systems on yield and quality of tomato Na pridelek in kakovost paradižnika, v svetovnem merilu najpomembnejše zelenjadnice, imajo lahko pridelovalni sistemi (PS) odločilen vpliv. Poljski poskus je bil izveden leta 2015 na trajnostnem poskusnem polju Fakultete za kmetijstvo in biosistemske vede v Pivoli, kjer je bil proučevan vpliv PS (ekološki, biodinamični, integrirani in konvencionalni) na pridelek in kakovost (vsebnost sladkorja, C-vitamina, nitratov in nitritov) dveh kultivarjev ('Jani' in 'Amaneta F1') paradižnika. Vsako obravnavanje je bilo oskrbovano skladno z zahtevami za določen PS in dobro kmetijsko prakso. Najvišja skupna masa pridelka je v konvencionalnem (56,71 t ha-1) in biodinamičnem (53,98 t ha-1) PS, v tržnem pridelku se pridelki med konvencionalnim (37,58 t ha-1), biodinamičnim (36,77 t ha-1), integriranim (31,43 t ha-1) in ekološkim (27,13 t ha-1) PS ne razlikujejo. Najvišja vsebnost sladkorja je v biodinamičnem (4,92 oBx) in ekološkem (4,88 oBx) PS. Najnižja vsebnost nitratov je v ekološkem (42,67 mg kg-1) ter v integriranem (44,33 mg kg-1) PS. Med kultivarjema je razlika v skupni in tržni masi pridelka, v vsebnosti sladkorja ter C-vitamina v prid kultivarja 'Amaneta F1', ki hkrati kopiči manj nitratov od kultivarja 'Jani'. Potrjeni vplivi PS na proučevane parametre so lahko dobra osnova za odločitev, kateri PS bo izbran za pridelavo paradižnika, pri čemer imajo glede kakovosti prednost manj intenzivni PS. The production systems (PS) can have a significant impact on the yield and quality of tomato, the world’s most important vegetable. In 2015, a field experiment was conducted on a sustainable experimental field, owned by the Faculty of Agriculture and Life Sciences in Pivola, which studied the impact of PS (organic, biodynamic, integrated and conventional) on the yield and quality (the contents of sugar, vitamin C, nitrates and nitrites) of two tomato cultivars ('Jani' and 'Amaneta F1'). Each treatment was provisioned in accordance with the requirements of a particular PS and good agricultural practice. In the conventional (56.71 t ha-1) and biodynamic (53.98 t ha-1) PS the total weight of the yield is the highest, while as far as the market yield is concerned, there are no differences between the conventional (37.58 t ha-1), biodynamic (36.77 t ha-1), integrated (31.43 t ha-1) and organic (27.13 t ha-1) PS. The highest sugar content is in the biodynamic (4.92 oBx) and organic (4.88 oBx) PS. The lowest nitrate content is in the organic (42.67 mg kg-1) and integrated (44.33 mg kg-1) PS. The two cultivars differ in the total and market weight of the yield, as well as in the contents of sugar and vitamin C, in favour of the cultivar 'Amaneta F1', which also accumulates less nitrates than the cultivar 'Jani'. The confirmed impacts of the production systems on the studied parameters can represent a solid basis for deciding which PS will be selected for the production of tomato. In terms of quality, the less intensive PS have a priority. paradižnik način pridelave pridelek kakovost tomato production system yield quality true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2016-09-19 19:57:56 2016-10-11 11:54:54 2022-07-04 03:06:03 2019-07-11 13:45:08 2016 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:19KVAYRS VS_Susek_Tine_2016.pdf VS_Susek_Tine_2016.pdf 1 D7B1E13AD209E0E267B91D14762ABEB4 6c1730dbc2302a4f5db3324edc433a675b0658fc70e262682c618aa106fc8654 921ef4d5-7c0d-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=105602 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
