20.500.12556/DKUM-71820 Različni pristopi h gnojenju češenj z dušikom Different aproaches to nitrogen fertilisation of cherry trees V letu 2016 smo v sklopu projekta CRP 1409 – Tehnologije pridelave hrušk in češenj in v okviru diplomskega dela opravili poskus na šest let starem nasadu češenj (Prunus avium L.) sorte 'Summit', cepljenih na podlago Gisela 5. Izvedli smo poskus gnojenja češnjevih dreves z dušikovim gnojilom KAN ter spremljali vpliv časa in odmerka na rast in rodnost dreves ter na kakovost pridelka. Poskus je zajemal dva faktorja, in sicer je prvi faktor predstavljal odmerek dušika (80 oziroma 120 kg N/ha), drugi faktor pa je predstavljal čas aplikacije gnojila (spomladi, jeseni). Za izvedbo poskusa smo zajeli 4 obravnavanja; 1. obravnavanje, kjer smo skupno dodali 120 kg N/ha (prvič spomladi, neposredno po cvetenju, drugič in tretjič pa z enomesečnim zamikom), 2. obravnavanje, kjer smo prav tako skupno dodali 120 kg N/ha (prvič jeseni, drugič spomladi neposredno po cvetenju in tretjič en mesec po cvetenju), 3. obravnavanje, kjer smo skupno dodali 80 kg N/ha (prvič neposredno po cvetenju in drugič z enomesečnim zamikom) ter 4. obravnavanje, kjer smo skupno prav tako dodali 80 kg N/ha (prvič jeseni, drugič pa spomladi, neposredno po cvetenju). Različni odmerki dušika in čas aplikacije gnojila so statistično značilno vplivali na vsebnost suhe snovi v plodovih; manjši odmerek (80 kg N/ha) in čas aplikacije gnojila v jeseni sta povečala vsebnost suhe snovi v plodovih v primerjavi z večjimi odmerki in z aplikacijo gnojila le v spomladanskem času. Statistično značilne razlike so bile tudi pri merjenju priraščanja debel, in sicer so najbolj priraščala drevesa, kjer smo večji odmerek dušika (120 kg N/ha) dodali v jeseni in spomladi. Odmerek dušika in čas aplikacije nista vplivala na količino pridelka in poprečno maso plodov. In 2016 we carried out an experiment, within the scope of project CRP 1409 – Pear and cherry tree production technology and in the framework of the thesis, on a six year old cherry plantation (Prunus avium L.) of the 'Summit' variety, grafted on the basis of Gisela 5. We conducted an experiment by fertilizing cherry trees with nitrogen fertilizer KAN and monitoring the influence of time and dose on the growth and fertility of trees and on the quality of the crop. The experiment covered two factors: the first factor was the nitrogen dose (80 and 120 kg N/ha), while the second factor was the time of application of the fertilizer (spring, autumn). The experiment was carried out in four treatments; 1. treatment where 120 kg N/ha was added in total (first in the spring, immediately after flowering, second and third time with a one-month delay), 2. treatment, where we also added 120 kg N/ha in total (first in the autumn, second time in the spring immediately after flowering and third time a month after flowering), 3. treatment, where we added 80 kg N/ha in total (first directly after flowering and secondly with a one-month delay), and 4. treatment, where we also added 80 kg N/ha (first in the autumn and the second time in spring, immediately after flowering). Statistically different doses of nitrogen and the time of application of fertilizers significantly influenced the content of the dry matter in the fruits; A smaller dose (80 kg N / ha) and the application time of the fertilizer in the autumn increased the dry matter content in the fruits compared to larger doses and the application of fertilizer only in the spring. Statistically significant differences were also observed in the measurement of tree trunk growth, out of which the trees that had the bigger dose of nitrogen (120kg N/ha) added in the autumn and in the spring had the largest growth. The nitrogen dosage and the time of application did not affect the amount of yield and average fruit mass. češnja gnojenje dušik pridelek cherry fertilization nitrogen yield true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2018-08-30 23:11:32 2018-09-10 13:16:04 2022-08-01 21:29:15 2019-07-11 18:55:42 2018 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:0NLIGCN2 UN_Planinc_Nina_2018.pdf UN_Planinc_Nina_2018.pdf 1 FE8C62F95C0FA0C82336B01D7424382B 7995f7c89f9f31103b048fadc0ceaeb7b04ebd22979f182424c066ec1bc29550 3f259846-7c10-11eb-bb7a-00155d0001ca 20.500.12556/dkum/571c82a6-deb4-4d6a-a3f0-3ff417f64c63 https://dk.um.si/Dokument.php?lang=slv&id=128547 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
