Razvoj ekološkog maslinarstva direktno je povezan sa razvojem ekološke poljoprivrede. Prve zabilježene podatke u EUROSTAT-u o količinama ekološki proizvedenih maslina imamo već 2002. godine za Italiju, da bi se od 2009. godine pratila i Hrvatska. Najveći dio ekološke proizvodnje maslina koncentriran je u Španjolskoj, Italiji i Grčkoj. Zakonodavstvo Europske unije (EU) konstantno se zalaže za stimulaciju i rast proizvodnje ekološke hrane i ekološkog načina proizvodnje. U Hrvatskoj, iako proizvodnja ekoloških maslina ima zabilježen značajan porast prinosa kao i uzgojnih površina, nailazimo na nerazumijevanje i nepoznavanje principa ekološke proizvodnje, neučinkovitu zakonsku regulativu, nepostojanje ekoloških rasadnika kao i vrlo mali broj uljara za preradu ekološki proizvedenih maslina.

The different sectors of the livestock industry play an important role in meeting the increasing demand for animal products in both Hungary and Croatia. The general objective of this study was to investigate and compare the efficiency of the livestock sectors in Croatia and Hungary using the Data Envelopment Analysis method. In this paper, the technical efficiency of the dairy, beef, broiler, sheep and goat, and pig sectors from 2014 to 2017 is investigated based on the Farm Accountancy Data Network database. This paper compared farms of different size classes based on the Standard Production Value for more detailed insights. Among the five main livestock sectors, Hungary performs better in terms of farm technical efficiency in the dairy and beef sectors, while Croatia has higher efficiency scores in the sheep sector. The performances in the pig and broiler sectors are almost the same in both countries. Moreover, in the Hungarian poultry, pig, sheep and goat sectors and the Croatian dairy, beef and pig sectors, the technical efficiency of small-sized farms is better than that of medium-sized farms.

Pregledni znanstveni članak Scientific review SAŽETAK Uspostava FADN sustava u Hrvatskoj omogućila je procjenu važnosti potpora za prihod poljoprivrednih proizvođača. Niski i nestabilni dohoci poljoprivrednih gospodarstava bili su glavni razlog za veliku državnu intervenciju na poljoprivrednome tržištu i transfere dohotka poljoprivrednicima. Prema analiziranim podacima, potpore imaju najveću važnost za tipove: govedarstvo, ovčarstvo i kozarstvo i mliječno govedarstvo, dok su o potporama najmanje ovisna povrćarsko-cvjećarska gospodarstva. Najmanji udio potpora u bruto prihodu imaju najveća gospodarstva (>500.000 EUR-a) i najmanja gospodarstva (4.000-8.000 EUR-a), a najveći ona ekonomske veličine 50.000-500.000 EUR-a. Udio potpora u ukupnome prihodu gospodarstva jednak je u Jadranskoj i Kontinentalnoj Regiji te ne ovisi o dobi nositelja gospodarstva. Budući da su hrvatska poljoprivredna gospodarstva dosta ovisna o potporama, a u svjetlu najavljenih promjena u novome programskome razdoblju Zajedničke poljoprivredne politike (2021.-2027.), moguće je očekivati smanjenje prihoda poljoprivrednih gospodarstava, na što je najosjetljiviji tip govedarstvo, ovčarstvo i kozarstvo.

This paper presents results of field measurements of working performance and fuel consumption evaluation in various operating conditions. Three versions of carrot extraction machines (Dewulf, Europa 2000 and Asa lift) at three locations and two varieties of carrots (Maestro F1 and Mello Yello F1) was. In optimum soil conditions, fuel consumption ranged from 8.4 to 12.5 L/ha, while in heavy operation conditions for extraction machines fuel consumption increased significantly for 65%. The performance of carrot extraction in optimal soil conditions was on average between 3-4 t/ha. In unfavorable soil conditions (soil sodden, mud or too dry soil) working effects up to 70% and this has direct negative consequences on the overall carrots production costs.

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 Original scientific paper
