Svrha ovoga istraživanja jest usporedba količine ekstrahiranoga kalcija i magnezija otopinom amonijeva acetata (AA) i otopinom Mehlich 3 (Mehlich 3) iz tala\u0000istočne Hrvatske. Ukupno 200 uzoraka oraničnih horizonata (0 - 30 cm) najzastupljenijih tipova tala prikupljeni su u pet županija istočne Hrvatske 2012. godine. Nakon određivanja pH vrijednosti i sadržaja ukupnih karbonata u tlu grupirani su uzorci tla (uzorci s manje od 3,5 i\u0000više od 3,5% CaCO3). Utvrđeno je da metoda Mehlich 3 ekstrahira više kalcija i magnezija od metode AA, a razlike u količini ekstrahiranih kationa izraženije su kod karbonatnijih tala (>3,5% CaCO3), posebno za kalcij. U tlima s manjim sadržajem CaCO3 utvrđena je statistički vrlo\u0000značajna korelaciju (P≤0,01) između metoda AA i Mehlich 3 u količini ekstrahiranoga kalcija i magnezija. Statistički je vrlo značajna korelacija (P≤0,01) utvrđena i između količina Mg AA i Mg Mehlich 3 u tlima sa sadržajem CaCO3 većim od 3,5%, što obje metode čini pogodnima za određivanje magnezija neovisno o sadržaju CaCO3 u tlu.","PeriodicalId":44286,"journal":{"name":"Poljoprivreda","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2019-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.18047/POLJO.25.1.6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48505756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sensory evaluation applies principles of experimental design and statistical analysis to the use of human senses aiming to isolate the sensory properties of foods themselves and provide important and useful information to product developers, food scientists, and managers about the sensory characteristics of food products. To achieve the scientific control of the sensory evaluation test, good laboratory practice should be applied. It includes defining the test objective and test type, selection of right assessors, ensuring right test area, handling and preparing the sample in appropriate way, paying attention to test set-up and storing the test data safe in logical order. \u0000Regarding eggs, sensory characteristics are usually evaluated on eggs enriched with bioactive compounds. Sensory studies are often conducted either with trained (in accordance with international reference standards) or untrained panelists. Sensory evaluation of eggs after addition of different compounds is of great importance because sensory attributes such as aroma, flavor, aftertaste and overall acceptability of enriched eggs are very important to consumers.","PeriodicalId":44286,"journal":{"name":"Poljoprivreda","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2019-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.18047/POLJO.25.1.8","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47641842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this research was to determine the concentration of nutritive values of macroelements (N, P, and K) and microelements (Fe and Zn) in a mushroom substrate and in a champignon mushroom fruiting body. A trial was conducted in the mushroom production company Romanjek LLC in Slavonski Brod, Croatia. It was conducted in four vegetation cycles on two different substrates, the one originating from Eastern Europe and the other originating from Northern Europe. At the end of the trial, the basic chemical properties of substrates and mushrooms were recorded. A comparison of investigated substrate measurements demonstrates that the highest content of elements N, P, and K was determined in the substrate 2 originating from Northern Europe, while the concentration of microelements Fe and Zn was higher in substrate 1, originating, from Eastern Europe. There was a statistically significant difference in a macroelement content in the mushrooms grown on the substrates of different origin, as well as in the transfer of Zn and Fe from a substrate to mushrooms. There was a higher accumulation of the transferred Zn in comparison to Fe in the mushrooms regardless of the origin of the substrate.","PeriodicalId":44286,"journal":{"name":"Poljoprivreda","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.18047/POLJO.25.1.2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67586862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For commercial use, an efficient propagation protocol is required. The aims of this study were to establish an efficient protocol for micropropagation and rooting of M. croatica. A number of factors were tested including the influence of 6-benzylaminopurine (BAP) and 1-naphthaleneacetic acid (NAA) at different concentrations as well as the effect of explant orientation and topophysis on shoot proliferation. Rooting was investigated in agar-based medium supplemented with indole-3-butyric acid (IBA) or indole-3-acetic acid (IAA) at various concentrations. Media with 1 and 2 mg/L of BAP produced the highest number of shoots/explant. However, the lower concentration of BAP should be recommended due to longer shoots without any sign of hyperhydration. Explant orientation and node position showed equal capability for shoot proliferation. Importantly, 100% efficiency of rooting was achieved in an agar-based rooting medium. Acclimatisation exceeded 90%. Taken together, an efficient protocol for micropropagation and rooting of M. croatica has been established for future production.","PeriodicalId":44286,"journal":{"name":"Poljoprivreda","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2018-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.18047/poljo.24.2.4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47189150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
