This study evaluated the presence of bioactives in wild nettle leaves and stalks during phenological stage context natural habitat diversity. Thus, samples collected before flowering, flowering after from 14 habitats situated three different regions (continental, mountain seaside) were analyzed for low molecular weight polyphenols, carotenoids chlorophylls using UPLC-MS/MS HPLC analysis, while ORAC method was performed antioxidant capacity measurement. Statistical analysis showed that, when...
The present study highlights the possibility of using sewage sludge-derived compost (SSC) or biochar (SSB) as valuable organic amendments. Such utilization sludge fulfills principles a carbon farming and nature-based solution strategy (NBS). This focused on detailed analysis quantitative qualitative changes in soil C compounds (total carbon—TC, total carbon—TOC, humic substances—CHS, labile carbon—LC, water extractable carbon—WEOC), which resulted from application SSC SSB; an assessment...
In this study, we investigated the influence of pedological parameters and variation altitude on mineral nutrients, phenolic compounds, antioxidant activities olive leaves. Samples Chetoui cultivar were collected from eight geographical locations with different altitudes. Levels compounds varied according to altitude. Classification revealed that 1 (>500 m) was characterized by high levels secoiridoids simple phenols, while 2 (500-300 3 (<300 higher in flavonoids. Mn, Ca B leaves level Zn...
Agricultural waste, which is produced in large quantities annually, can be a threat to the environment. Biochar (BC) production represents potential solution for reducing amount of grapevine pruning residues and, accordingly, impact on environment and climate change. by process pyrolysis from was investigated characterized applied as an adsorbent polyphenolic compounds with aim using waste viticultural obtain quality product adsorption recovery potential. Standards caffeic acid (CA), gallic...
Organic amendments are often reported to improve soil properties, promote plant growth, and crop yield. This study aimed investigate the effects of biochar compost produced from sewage sludge olive pomace on hydraulic water flow, P transport (i.e., sorption) using numerical modeling (HYDRUS-1D) applied two types (Terra Rosa Rendzina). Evaporation leaching experiments cores repacked columns were performed determine retention, conductivity, potential, sorption capacity these mixtures. In...
In modern agriculture, besides providing high and stable yields, it is imperative to produce products with a nutritive quality. The goal of this study was determine the effect different fertilization regimes on macro- micronutrients in beetroot. A 3-year field trial set up according Latin square method four types (unfertilized control, 50 t manure ha−1, 500 1,000 kg NPK 5-20-30 ha−1). mineral content determined as follows (mg 100 g−1 fresh weight beetroot): 14–29 P, 189–354 K, 18–34 Ca,...
Plant-based fertilizers, such as liquid plant extracts, contribute to the cultivation of vegetables, particularly in organic production. The objective this study was determine if aqueous nettle extract could be successfully used a fertilizer, applied on soil and foliarly, green bean production under field conditions. hypothesis that it replace mineral fertilizers integrated into sustainable agriculture. experiment conducted at two climatically pedologically different locations (Zadar Poreč)...
The sensory properties of fruit and vegetables are a result taste aroma caused by many volatile nonvolatile compounds. sum organic acids (malic citric acids) soluble sugars (fructose glucose), as well their balanced combination interaction, contributes to the characterization tomato flavour. ratio is key sweetness sourness tomatoes. This study aimed determine sugar acid content, several physicochemical parameters, eight landraces from Croatia. All parameters investigated differed between...
Shallots are a perennial plant from the Alliaceae family, classified with common onion under name of Allium cepa Aggregatum group. The term shallot is also used for diploid and triploid viviparous onions, known as × proliferum (Moench) Schrad cornutum Clementi ex Vis., respectively. In this study, we compared dry matter, pyruvic acid content, sugar flavonoid antioxidant capacity mineral composition 34 accessions falling into three species (Allium cornutum, A. Aggregatum). Shallot belonging...
One of the limiting factors in organic farming is scarcity allowed fertilizers and chemicals for plant protection. Plant compost extracts are a promising solution fertilization because their positive effect on growth soil microbial activity. Nettle extract was already successfully applied to some vegetables. Not-aerated nettle extract, obtained from dry leaves, experiments with green beans quantity 1 L per pot at two-day intervals studied. A three-factorial experimental design two types...
Abstract BACKGROUND The present study aimed to examine the effect of foliar (Mn_fol) and soil Zeolite‐Mn (Mn_ZA) application on leaf mineral, total phenolic oleuropein content, mycorrhizae colonization self‐rooted cv. Leccino plantlets grown calcareous soil. RESULTS dissolution zeolite was 97% when citric acid applied at 0.05 mM dm −3 , suggesting that organic acids excreted by roots can dissolve modified (Mn_ZA), making Mn available for plant uptake. concentration highest Mn_fol treatment...
The Leccino olive cultivar was grown in pots contained calcareous rendzina soil amended with NPK fertilizer (control treatment) or further addition of Zeolite A (ZA) containing either zinc (Zn2+) manganese (Mn2+) (Zn-ZA and Mn-ZA). After one year, vegetative growth root morphological parameters were measured elemental analysis performed on the root, stem, leaves. Compared to other treatments, Zn-ZA enhanced Zn concentration total quantity leaves, as well diameter. volume greater using...
Manganese (Mn) is an essential element that intervenes in several plant metabolic processes. The olive tree, and its fruits leaves, are known as a source of nutraceuticals since they rich biophenols. However, there still serious lack data about biophenolic distribution stems roots under Mn fertilisation. In this context, our study aimed to examine the effects fertilisation on profile stems, ‘Istarska bjelica’ cultivar. experiment was set up greenhouse, during period five months, random block...
Onion peels (OP) are rich in bioactive compounds with a plethora of benefits for human health, but this valuable material is often wasted and underutilized due to its inedibility. Likewise, grapevine pruning residues commonly treated as agricultural waste, biochar (BC) obtained from has favorable characteristics an adsorbent. This study investigated the potential BC removal targeted polyphenolic OP extracts. The extracts were adhering green chemistry principles using deionized water...
Aroma profiles and phenolic components of white wines made from 'Pošip' 'Škrlet' (Vitis vinifera L.) both native Croatian, non-aromatic grape varieties enhances the knowledge about these varieties, prepared without maceration (control) subjected to pre-fermentative cold (CM). Individual compounds in were determined by high-performance liquid chromatography (HPLC) system, while total phenolics flavan-3-ols spectrophotometric methods. CM had significant impact on composition wine. The increase...
This study investigates the effect of combined sulfur (S) and nitrogen (N) foliar fertilization on leaf S N concentration, as well growth olive fruit quantity quality oil, obtained from two cultivars ‘Istarska bjelica’ ‘Leccino’ in consecutive years. are some most important nutrients, both play a crucial role plant oil production. The here-reported program significantly increased concentration leaves without affecting which led to an increase yield improvement all morphological parameters....
