20.500.12556/DKUM-63687 Vpliv apnenca iz morskih alg na parametre kakovosti pri sorti jablane 'Pinova' (Malus domestica B.) Influence of limestone extracted from seaweed on quality parameters by apple variety Pinova Leta 2010 smo na posestvu Fakultete za kmetijstvo in biosistemske vede izvedli poskus s kalcijevim gnojilom LITHO KR+. Poskus je bil izveden v nasadu jablan sorte 'Pinova' na parceli Vrecl. V poskus smo vključili 42 dreves. Obravnavanje so predstavljala kontrola (brez dodatnega gnojenja) in gnojenje z LITHO KR+ v tla. Poleg spremljanja bujnosti rasti smo ob obiranju plodove stehtali in razvrstili v kakovostne razrede glede na premer plodov in obarvanost. Nato smo plodove testirali na trdoto mesa plodov, vsebnost suhe snovi, škrobni indeks in vsebnost kislin. Ugotovili smo, da uporaba kalcijevega gnojila LITHO KR+ nima vpliva na vegetativno rast jablan sorte 'Pinova', prav tako nima statistično značilnega vpliva na količino pridelka. Ima pa vpliv na izboljšanje trdote plodov in višjo vrednost Streifovega indeksa zrelosti. Analiza podatkov je namreč pokazala, da je trdota mesa plodov po uporabi omenjenega gnojila višja. Prav tako kalcijevo gnojilo LITHO KR+ vpliva na boljšo obarvanost plodov. Analiza nam je potrdila, da gre za statistično značilne vplive gnojila LITHO KR+ na večji delež primerno obarvanih plodov, kar definira tržno vrednost jabolk. In 2010, we carried out an experiment on estate of the Faculty of Agriculture and Life Sciences using LITHO KR+ calcium fertiliser. The experiment was carried out on apple trees of the ‘Pinova’ variety growing on the Vrecl plantation. The experiment included 42 trees. The experiment included a control group (without additional fertilising) and a group in which the LITHO KR+ fertiliser was added to the soil. After harvest, we weighed the apples and divided them into quality grades according to the diameter and colouring of the fruit. Then tests were carried out for hardness of the fruit flesh, dry matter content, starch index and acidity content. We came to the conclusion that the use of the LITHO KR+ calcium fertiliser does not have an influence on the vegetative growth of the apple trees of the ‘Pinova’ variety, nor does it have a statistically significant influence on the yield. However, it does improve fruit hardness and results in higher values on the Streif index. Data analysis has shown that the level of hardness is better and higher after the use of mentioned fertilizer. Additionally, LITHO KR+ calcium fertiliser has a favourable influence on the colouring of the fruit. The analysis has confirmed that LITHO KR+ fertiliser has a statistically significant influence on a higher share of better coloured apples (over 50 % of red colour), that defines the market value of apples. sadjarstvo / kalcij / aktivator tal / kakovost / obarvanost / 'Pinova' fruit-growing / calcium / soil activator / calcium / quality / colouring / ‘Pinova’ true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2016-09-14 19:07:20 2016-10-11 07:15:15 2022-07-03 03:06:26 2019-07-11 13:36:04 2016 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:BTCKR1M0 UN_Protner_Denis_2016.pdf UN_Protner_Denis_2016.pdf 1 C651C08E85D799A18E4ADD733F68D787 5a89fa73c9f80c050877a5220d2660b855151bd619f91ee8369f9208f2b0acbc 81782a5e-7c0d-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=104875 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
