20.500.12556/RUL-186654 Vpliv različnih režimov namakanja na količino in kakovost pridelka lubenice (Citrullus lanatus) Impact of different irrigation regimes on the yield and quality of watermelon (Citrullus lanatus) Optimalno količino in kakovost pridelka lubenice zagotavljamo z natančnim namakanjem. Kmetijstvo je eden največjih porabnikov vode na svetu, zato je natančna raba vode izjemno pomembna, saj nam pomaga zmanjšati okoljske pritiske na omejene vodne vire in krepiti podnebno odpornost. V okviru diplomskega dela je bil opravljen pregled literature in ugotovljeno je bilo, da je lubenica najbolj občutljiva na pomanjkanje vode v fazi pozne vegetativne rasti, cvetenja in predvsem v fazi oblikovanja plodov, pri čemer je zmeren vodni deficit povzročil največje zmanjšanje pridelka. Nasprotno je faza zorenja primerna za izvajanje deficitnega namakanja brez večjih izgub pridelka, hkrati pa izboljša nekatere parametre kakovosti plodov, kot so vsebnost topne suhe snovi, sladkorjev in vitamina C. Ugotovljeno je bilo tudi, da so pri zmernem vodnem deficitu izgube pridelka najmanjše glede na dosežene prihranke vode. Zaradi pomanjkanja sladke vode je bila proučevana možnost namakanja s slano vodo, vendar je bilo ugotovljeno, da povečana slanost negativno vpliva na rast in pridelek lubenice. Kapljično namakanje se je v smislu porabe vode izkazalo za učinkovitejše od namakanja z razpršilci. Cepljenje lubenic je pozitivno vplivalo na pridelek in velikost plodov, v primerjavi z necepljenimi lubenicami. Optimal watermelon yield and quality can be achieved through precise irrigation management. Agriculture is one of the largest consumers of water worldwide; therefore, efficient water use is extremely important, as it helps reduce environmental pressure on limited water resources and enhances climate resilience. Within the framework of this bachelor's thesis, a literature review was conducted, revealing that watermelon is most sensitive to water deficit during the late vegetative growth stage, flowering, and especially during fruit development, with moderate water deficit causing the greatest reduction in yield. In contrast, the ripening stage is suitable for the application of deficit irrigation without significant yield losses, while also improving certain fruit quality parameters, such as soluble solids content, sugar content, and vitamin C concentration. It was also found that under moderate water deficit, yield losses were minimal relative to the achieved water savings. Due to the scarcity of freshwater resources, the possibility of irrigating with saline water was examined; however, increased salinity was found to negatively affect watermelon growth and yield. Drip irrigation proved to be more water-efficient than sprinkler irrigation. Grafting watermelon plants had a positive effect on yield and fruit size compared with non-grafted watermelons. lubenica Citrullus lanatus namakanje vodni deficit pridelek kakovost watermelon Citrullus lanatus irrigation deficit irrigation yield fruit quality true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-04 07:15:52 2026-09-04 07:16:02 2026-09-07 09:10:45 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 286853 290149123 60585.pdf 60585.pdf 1 0BF777DE23734C605ECA66EA4AD66CF8 4c13e7631c8c46c89d1e88d60623878baf8f23887b0b3ee064fc00f1f24186f5 b8754b13-a81f-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=245971 Biotehniška fakulteta 0 0 0
