Since the nineties of the last century, ecological products have become increasingly important in the market, and given that scientists have pro and contra arguments of ecological breeding, the main ...purpose of this paper was to determine the consumer's preferences towards ecological food; the importance of certain characteristics and deterrents on the purchase of organic food; in the market of Split. For this survey we randomly recruited 113 participants in Split, Croatia. Surveyed consumers when purchasing organic food of the greatest importance consider protection of the environment, and at the least important they retain the taste. The most significant constraint on purchasing organic food of surveyed consumers is the high cost of the product, and the least important is the lack of marketing. Given the size of the sample, surveyed consumers are a typical target group of consumers of organic food.
Traditionally grown domesticated apple varieties are known for their adaptability to different climates and a wide range of soil types, and some for resistance to the main diseases. Their evaluation ...and preservation are very important, not only for restoration of traditional orchards, but also as a source of genetic material for breeding new varieties. Micropropagation of the most valuable varieties could be a way to propagate plants for restoration of traditional orchards, or as a prerequisite for ex situ long-term conservation through cryopreservation. Fruit samples were taken from trees 50 or more years old, of 13 traditionally grown domesticated apple varieties in Bjelovar Bilogora County in Croatia. Morphological traits of the fruits were evaluated during 3 years, and chemical characteristics (soluble solids, reducing sugars, acids and total phenol content) were evaluated during one vegetation year. Tissue culture was established from shoot apices approximately 1 mm in size isolated from buds of 1-year-old scion woods. Axillary branching was induced from two types of explants on MS medium with the addition of 2% glucose, 1% sucrose, 0.1 g L−1 myo-inositol, 0.8% agar, 0.2 mg L−1 gibberelic acid (GA3), 0.1 mg L−1 indole-3-butyric acid (IBA) and 1.5 mg L−1 6-benzylaminopurine (BAP) in proliferation medium 1 (PM1) or 2 mg L−1 zeatin (ZEA) in proliferation medium 2 (PM2). The morphological characteristics of the traditionally grown domesticated apple varieties mentioned were not different from their standard values. Average fruit weight (AFW), average fruit height (AFH) and average fruit diameter (AFD) were less than standard values, which can be explained by the age of the fruit trees. Principal component analysis of these traditionally grown domesticated apple varieties showed that fruit traits very important in today’s breeding for new cultivars, like fruit weight, shape, skin color and flesh taste, stand out in explaining the variability. Despite the age of the fruit trees, the fruits still have surprisingly positive chemical characteristics, especially Canadian Reinette for which the highest concentration of total phenols was found. Of the five traditionally grown domesticated apple varieties used, tissue culture was successfully established for Jonathan and Canadian Reinette varieties. Higher multiplication efficiency was obtained for the Jonathan variety. Medium supplemented with 1.5 mg L−1 BAP produced a significantly higher number of shoots/explant in comparison with those supplemented with ZEA. Morphological features of shoots produced on medium supplemented with ZEA, however, were better. Both explant types, shoots placed in the medium vertically or two-nodal stem segments placed in the medium horizontally, gave similar results for axillary branching.

The aim of the research was to learn from a survey about the production and economic characteristics of sheep production as well as economic position and developmental orientation of sheep breeders ...on the island of Pag. Data on production and economic characteristics of sheep production on the island of Pag were collected from a survey and processed through relevant descriptive statistics methods. The respondents have on average 47 breeding sheep, 2 rams and 9 sheep intended for flock renewal rate (not older than one year); which means an average flock has 58 sheep. The average total income from sheep production in 2009 was 72,460.10 HRK. The average total production costs in 2009 were 13,260.10 HRK, including the costs of fodder and veterinary services. All farms achieved positive financial results of 59,199.90 HRK in average. As many as three quarters of respondents indicated profitability of sheep production as the main motivation to engage in sheep production; very few indicated that heritage and inability to do other jobs were the main motivation. Important limiting factors for future development of sheep breeding on the island of Pag in most farms are lack of potential heirs and high average age of farm holders. Regarding the effects of joining the European Union, half the breeders intend to improve their production and harmonise it with the EU requirements and standards; one quarter of them intend to keep the existing production capacity; and another quarter intend to quit with production.
Permakultura je svjesno oblikovanje i održavanje poljoprivredno produktivnih ekosustava te zauzima svoje mjesto i značajna je u suvremenoj poljoprivredi i tranziciji prema samoodrživosti. Obzirom na ...poljoprivrednu proizvodnju, permakultura se trudi dati praktična rješenja u proizvodnji hrane koja su vezana uz ekološku održivost promjenom socijalno - ekonomske slike svijeta uz promjenu kulture, pristupa tehnologiji i promjenu ekonomije. Kroz načela permakulture dolazi do integracije ljudi i krajolika, koji na održivi način osiguravaju hranu, energiju, sklonište i ostale materijalne i nematerijalne potrebe. Posao voćara se uvelike mijenja ako preuzme permakulturni svjetonazor od načina tehnologije uzgoja do plasmana proizvoda na tržište gdje se pored voća plasiraju i različiti drugi proizvodi. Koristi ostvarene ovakvim sustavima gospodarenja ne mogu se mjeriti s onima ostvarenima intenzivnim načinom uzgoja.
Permaculture is the conscious design and maintenance of agriculturally productive ecosystems. It takes its place and is significant in modern agriculture and in the transition to self-sustainability. With regards to agricultural production, permaculture strives to provide practical solutions in food production that are related to environmental sustainability by changing the socio - economic picture of the world. It
acts by changes in culture, access to technologies and changes in the economy. Through the principles of permaculture, there is an integration
of people and landscapes, which is a sustainable way that provides food, energy, shelter, and other tangible and intangible needs. The job of a fruit grower changes greatly if he takes a permaculture worldview from the mode of cultivation technology to the arrival of the product on
the market where in addition to fruit it comes with different products.
The benefits achieved by such systems cannot be measured with those achieved by intensive modern orchards.
Žižula (Ziziphus jujuba Mill.) je voćna vrsta porijeklom iz Kine gdje se uzgaja gotovo 4000 godina. Po broju stabala najbrojnija je voćna vrsta u Kini. Plod je koštunica koji može biti oblog ili ...izduženog oblika, od veličine višnje pa do veličine šljive i karakterističnog je slatko-kiselog okusa. Žižula je izuzetno specifična zbog svoje neobične strukture izbojaka te kasnijeg kretanja i ranijeg završetka vegetacije u odnosu na ostale voćne vrste. Plodovi su izuzetno bogati vitaminom C. Neizostavan je dio prehrane u Kini te ima veliku važnost u tradicionalnoj medicini za liječenje mnogobrojnih bolesti. U Hrvatskoj se žižula može pronaći u Istri i Dalmaciji gdje se najčešće koristi kao samostalno stablo u dekorativne svrhe. Najpovoljnije vrijeme sadnje za žižulu je u proljeće u vrijeme bubrenja pupova. Berba žižule počinje od kraja kolovoza i traje do studenoga ovisno o sorti. Plodonošenje počinje u drugoj godini nakon sadnje, a punu rodnost nakon 4 do 5 godina. U voćnjacima se prirodi kreću od 18 do 50 kg po stablu. Zbog svoje izuzetne otpornosti na sušu te prilagođenosti mediteranskoj klimi, žižula je izuzetno zanimljiva voćna vrsta za uzgoj.
Chinese jujube (Ziziphus jujuba Mill.) is a fruit tree that originates from China. It is cultivated for more than 4000 years. Fruit is a drupe which varies in shape (from round to elongated) and size (from cherry like to plum like). Chinese jujube tree is very specific because of its shoot structure and late start of growth and early leaf fall compared to
other fruit trees. Fruit is rich in vitamin C and it is essential part of diet in China as well as big part of traditional medicine for treating many illnesses. Chinese jujube can be found in parts of Croatia
like Istria and Dalmatia where it is used as a solitary ornamental tree. The best time to plant jujube is in the spring during bud swelling. Jujube harvest begins in late August and lasts until November depending on the variety. Fruiting begins in the second year after planting and gains full yield after 4 to 5 years. In orchards yields ranging from 18 to 50 kg per tree. Chinese jujube is very interesting fruit for cultivation because of its drought resistance, small demands on soil type and quality and adaptation in Mediterranean climate.
Alepski bor (Pinus halepensis Mill.) se koristio u pošumljavanju krša šibenske regije od sredine 19. stoljeća, te se zbog toga ova vrsta često javlja u ranije zasnovanim parkovima. Upravo zbog ...poznatih dekorativnih karakteristika, te kulturološke vrijednosti, cilj rada je izvršiti inventarizaciju i predočiti estetsku ocjenu zelenih površina s alepskim borom. U tu svrhu provedena je taksonomska analiza vrsta na zelenim površinama s alepskim borom. Florističko i anketno istraživanje je provedeno tijekom 2013. godine na području grada Šibenika. S obzirom na tip habitusa po Erhardtu i sur., 2002. dominiraju grmolike forme i alohtone dendrološke svojte. Temeljem rezultata istraživanja vizualnog dojma „geštalta”, putem anketnog ispitivanja, zaključak je da ispitanici ugodno doživljavaju parkovne prostore s alepskim borom.

Klimatske promjene stavljaju na kušnju maslinare 21. stoljeća te ih prisiljavaju na adekvatnu i provjerenu tehnologiju uzgoja u cilju zaštite od potencijalnih prijetnji. Zemlje mediteranskog bazena ...suočavaju se s velikim promjenama i izazovima koje uzrokuju posljedice globalnog zatopljenja kao što su temperaturni ekstremi i nepovoljan raspored oborina. Mnoge regije postaju nepogodne za uzgoj maslina, dok se u drugima počinju stvarati idealni uvjeti za maslinarstvo i poljoprivrednu proizvodnju općenito. Grčka i Italija su pretrpjele ogromne gubitke uslijed klimatskih promjena, stoga nam njihovi primjeri služe kao okosnica u kreiranju razvojnih strategija za maslinarstvo.
Climate change will challenge 21st century olive growers and force them to practice adequate and proven cultivation technologies to protect themselves against potential threats. The Mediterranean basin countries are facing major changes and challenges caused by the effects of global warming such as temperature extremes and unfavorable distribution of precipitation. Many regions are becoming inadequate for olive cultivation, while others are beginning to create ideal conditions for olive growing and agricultural production in general. Spain, Greece, and Italy have suffered enormous losses due to uncontrolled climate changes, so their examples might serve as a backbone in the development of olive growing development strategies.
Upotreba sobnog bilja potječe još iz davne povijesti čovječanstva. Većina sobnog bilja koja se koristi u ukrašavanju interijera dolazi iz tropskih i suptropskih područja, dok ih manji broj dolazi iz ...umjerene klime. Prilikom odabira biljke za ukrašavanje interijera, važno je imati na umu da neke biljke nisu uvijek „moderne“ te također da ljudi imaju različita mišljenja vezano uz takav odabir. Cilj ovog rada je odrediti odgovarajuće sobno bilje za interijer jedne institucije visokog obrazovanja te utvrditi cjelokupni vizualni dojam (vizualni „geštalt“) putem ankete vezane uz određene odabrane lončanice u interijeru prostorija Veleučilišta „Marko Marulić“ u Kninu. Istraživanje je provedeno putem ankete tijekom studenog i prosinca 2014. godine na uzorku od 43 ispitanika (studenata i zaposlenika). Ustanovljeno je da su različite palme i lončanice dobile najbolje ocjene i najbolje su prihvaćene za upotrebu u interijeru Veleučilišta.
U Hrvatskoj se posljednjih godina povećala ukupna površina pod ekološkom poljoprivredom kao i površine pod ekološkim voćnjacima. Analizom ponude na izravnim i neizravnim prodajnim kanalima u Gradu ...Zagrebu tijekom 2017. godine utvrđeno je da je domaće ekološko voće prvenstveno zastupljeno u izravnim kanalima (tržnice). U neizravnim kanalima (hipermarketi i specijalizirane prodavaonice) ponuda voća je veća, no ono je prvenstveno iz zemalja EU. Ponuda domaće proizvedenog ekološkog voća na području Grada Zagreba nije zadovoljavajuća, ali budući da se radi o višegodišnjim kulturama, možemo očekivati povećanje ponude, homogeniju kvalitetu i dostatne količine te prisutnost i na drugim prodajnim kanalima.
