Flea beetles (Phyllotreta spp.), cabbage stink bugs (Eurydema ventrale) and onion thrips (Thrips tabaci) cause significant economic problems to cabbage growers in Slovenia. The aim of our study was ...to assess the potential effect of the epicuticular wax on leaves as defence mechanism against these three cabbage pests. The impact of epicuticular wax content in relation to damage levels of cabbage pests was studied under field conditions at the Experimental Field of the Biotechnical Faculty in Ljubljana on 12 cabbage cultivars (Brassica oleracea L. var. capitata). These insect pests showed weak preference on cabbage heads with high epicuticular wax. There was a strong negative relationship between epicuticular wax content and the level of plants infested (r2 = -0.8399 for flea beetles, r2 = -0.7413 for cabbage stink bugs and r2 = -0.7042 for onion thrips). The cv.‘Holandsko pozno rdeče’, showed itself to be the most resistant to the cabbage stink bugs and onion thrips, while cv. ‘Red Dinasty’ was the most resistant against flea beetles.
Kapusov bolhač (Phyllotreta spp.), pisana stenica (Eurydema ventrale) in tobakov resar (Thrips tabaci), povzročajo gospodarsko pomembne težave pridelovalcem zelja v Sloveniji. Cilj naše raziskave je bil oceniti potencialni učinek epikutikularnega voska na listih kot obrambnega mehanizma proti naštetim škodljivcem. Vpliv količine epikutikularnega voska na poškodbe, ki jih povzročajo škodljivci, smo proučevali na 12 kultivarjih zelja (Brassica oleracea L. var. capitata), vzgojenih na Laboratorijskem polju Biotehniške fakultete v Ljubljani. Škodljivci so pokazal majhno preferenco do zeljnih glav, ki imajo visoko vsebnost epikutikularnega voska. Med koncentracijo epikutikularnega voska in poškodovanimi listi je bila namreč ugotovljena močno značilna negativna povezava (r2 = -0.8399 za kapusovega bolhača, r2 = -0.7413 za pisano stenico in r2 = -0.7042 za tobakovega resarja). Cv.‘Holandsko pozno rdeče’, se je pokazal kot najbolj odporen kultivar ob napadu tobakovega resarja in pisane stenice, medtem, ko je bil cv. ‘Red Dinasty’ najmanj odporen proti napadu kapusovega bolhača.
The main agricultural importance of Trichoderma species was not so far away mainly suppression of plant diseases. Novel investigations emphasize their potential to stimulate plant growth ...independently of suppression of any plant disease. However, Trichoderma spp. and even biotypes of same species vary between each other in its effectiveness both in the control of plant pathogenic fungi and in the promotion of plant growth and increasing yield. The subject of this study was to evaluate growth promoting effect of two indigenous T. viride stains STP16 and STP8 on cabbage and red beet. Increment of fresh and dry weight accomplished by STP16 was statistically significant so, it could be concluded that growth enhancement of 27% at red beet and 29% at cabbage is significant.
The plant spacing of early cabbage (Brassica oleracea L. var. capitata) was studied at the Experimental Field of the Biotechnical Faculty in Ljubljana, during the 2001 and 2002 growing season. The ...cultivars, which included "Vestri", "Parel", "Delphi", "Destiny" and "Hermes", were each spaced at 20, 30 and 40 cm within rows and 30 cm between rows or populations equivalent to 166,000, 108,000 and 82,000 plants ha-1. The experimental variables measured were marketable yield (per head and per hectare), yield characteristics (head diameter and head volume), quality characteristics (core volume, head density, soluble solids and dry matter) and onion thrips damage ratings. There was no interaction effect of cultivar and planting spacing on the measured variables. Marketable yield per head, head diameter and volume, core volume and head density generally increased as the within-row plant spacing increased, whereas, dry matter was significantly decreased at lower plant spacing. Soluble solids were not affected by plant spacing. The yield potential of cabbage was higher at cv. "Vestri" than at the other cultivars. The onion thrips damage rating was severe at the lowest plant spacing and contributed to the reduced yield. A higher damage rating was established in the cv. "Parel" but this didn't have a statistically significant influence on the weight loss of yield.
The impact of water-soluble carbohydrate composition in relation to damage levels of onion thrips (Thrips tabaci Lindeman), were studied under field conditions at the Experimental Field of the ...Biotechnical Faculty in Ljubljana on 7 cabbage cultivar (Brassica oleracea L. var. capitata). Onion thrips showed weak preference on cabbage heads with high amount of total carbohydrate, fructose and glucose and higher preference on heads with high concentration of sucrose. While amount of total carbohydrate, fructose and glucose were negatively correlated with damage levels (r2 = -0.7667; r2 = -0.6947; r2 = -0.8263), sucrose amount was not. There was a strong positively relationship between sucrose amount and the level of plants infested (r2 = +0.7378). The cv."Hinova", which had the highest amount of total carbohydrate, showed itself to be the most resistant to the onion thrips.
Sorta Varaždinsko zelje jedna je od najtraženijih domaćih čuvanih sorti kupusa. Neovisno o vremenu sadnje Varaždinskog zelja postoji velik broj štetnih organizama koji ugrožavaju uspješnu proizvodnju ...u polju. U proteklih nekoliko godina neke biljne bolesti gotovo su potpuno uništile pojedina polja kupusa, a jedna od tih bolesti jest bakterijska tamna trulež žila (Xanthomonas campestris pv. campestris). Simptomi su najviše izraženi tijekom toplog i vrlo vlažnog razdoblja. Zaražene presadnice bitni su čimbenik u pojavi i širenju te bolesti. Pokus je proveden na biljkama u polju koje su uzgojene iz presadnica varaždinskog zelja, uz dva različita tretmana dezinfekcije sjemena: sjemena podvrgnuta termoterapiji te sjemena tretirana natrijevom lužinom. Tijekom vegetacije u pokusu je proveden program folijarne zaštite koji je obuhvaćao četiri roka aplikacije. Program folijarne zaštite proveden je u nasadu s presadnicama uzgojenim iz netretiranog sjemena te s presadnicama uzgojenim iz sjemena obrađenih termoterapijom. Pokus s folijarnom zaštitom sastojao se od šest različitih tretmana te jedne netretirane varijante (kontrole). Na pokusnim parcelama u dva roka provedena je vizualna procjena postotka zahvaćenosti površine lista simptomima. Nakon provedenih različitih folijarnih tretmana uočena je značajna razlika između biljaka uzgojenih iz netretiranog sjemena i biljaka dobivenih iz sjemena obrađenog termoterapijom. Manje simptoma bilo je na biljkama koje potječu od tretiranog sjemena. Također je iz provedenih pokusa bilo vidljivo da je folijarna zaštita umanjila pojavu simptoma.
Varaždinsko zelje (Brassica oleracea var. capitata f. alba) je povrtna kultura dobivena od izvorne sorte Varaždinski kupus, koji se na području Varaždinštine proizvodi za komercijalne svrhe. Pisani ...povijesni tragovi o uzgoju zelja datiraju od druge polovice 18. stoljeća, te se navode u brojnim časopisima i znanstvenim radovima. Specifične kvalitativne karakteristike varaždinskoga zelja uvjetovane svojstvima tla, reljefa, klimatskim uvjetima i utjecajem ljudskih čimbenika na proizvodnju, dobivene su dugogodišnjom prilagodbom metoda i primjenom stečenih znanja u proizvodnji. U cilju zaštite izvornosti, varaždinsko zelje proizvodi se na tradicionalan način, na ograničenom zemljopisnom području Varaždinske županije u sustavu kontrole izvornosti, podrijetla i kvalitete. Važnost zaštite izvornosti proizvoda bazira se na činjenici da varaždinsko zelje predstavlja izvorni hrvatski proizvod proizveden od izvorne hrvatske sorte te je ujedno simbol i doprinos održavanju vlastite agrobioraznolikosti.
Provider: - Institution: - Data provided by Europeana Collections- Začetek kamniške tovarne Eta sega v leto 1923. Prvi lastniki podjetja so bili Ljubljančan Franc Kham ter Kamničana Stanko, ki je ...podjetje poimenoval po svoji hčeri, in Ignac Žargi. Podjetje so ustanovili z lastnim kapitalom in ga postavili v gospodarskem poslopju Kmetijske nabavne in prodajne zadruge na naslovu Šutna 22. Danes tam stoji stanovanjsko poslopje s pritličnim delom, v katerem sta dolgo gostovali trgovina Metalka in med gimnazijci zelo priljubljena slaščičarna.Že na začetku so v malem družinskem obratu izdelovali vse legendarne izdelke, po katerih smo poznani še danes, predvsem gorčico. Navsezadnje so si najprej nadeli ime Eta – tovarna gorčice.Več o zgodovini kamniške Tovarne Eta.Prispeval: Medobčinski muzej Kamnik- All metadata published by Europeana are available free of restriction under the Creative Commons CC0 1.0 Universal Public Domain Dedication.

Pomanjkanje prave kulture skrbi za stavbe je v večini razvitih mest pripeljalo do resnih težav zaradi propadanja mestnih predelov, in to ogroža zdravje in varnost mestnih skupnosti. Sanacija je ...pristop, s katerim navadno ustavimo propadanje in obnovimo propadajoča območja. Pogosto pa ima tudi negativne posledice; zmoti lahko delovanje obstoječih socialnih mrež in pretirano poveča količino odpadkov, ki nastanejo pri gradnji in rušenju zgradb. Po drugi strani je obnova stavb socialno in okolju prijaznejša izbira v primerjavi s prenovo, vendar je njen uspeh kar najbolj odvisen od sodelovanja stanovalcev. Če želimo doseči trajnostno strategijo urbane prenove, moramo najti ravnotežje med interesi različnih déležnikov za enega od obeh glavnih pristopov k prenovi. Čeprav je pomembno, da pri sprejemanju odločitev upoštevamo ekonomska in fizična vprašanja, se v tej raziskavi s strukturirano anketo preučujejo želje in preference lokalnih prebivalcev glede teh dveh možnosti. Ugotovitve prispevajo k razvoju uravnotežene in socialno trajnostne strategije urbane prenove.
