An increase in the reliance on biomass energy production results in an increased ash production, as a residue subsequent to the biomass combustion. As an alternative to the disposal of ash in landfills, the use of ash in agriculture is becoming increasingly important. The value of ash as a calcifying material, fertilizer, or soil improvement material, as well as a possibility of application and the amount of ash applied in forage production on an arable land or grassland, depend on the content of macro- and micronutrients, the potential neutralization value, and on the content of heavy metals and other potential pollutants. Biomass ash, which contains the significant amounts of nutrients (Ca, K, Mg, P, Fe), can be applied as a calcifying material affecting the soil’s physical and chemical properties, soil microbiological activity, and soil decomposition and ultimately increases crop productivity. The application of ash on grasslands and in the forage production in the amount 6-22 t ha-1 results in an increased productivity of forage species, the proportion of legumes in the sward, and the nutritional value of forage.
对生物质能源生产的依赖增加导致灰烬生产增加,灰烬是生物质燃烧后的残留物。作为垃圾填埋场处理灰烬的替代方案,灰烬在农业中的使用变得越来越重要。灰作为钙化材料、肥料或土壤改良材料的价值,以及在耕地或草地上的饲料生产中应用的可能性和应用的灰量,取决于宏观和微量营养素的含量、潜在的中和值以及重金属和其他潜在污染物的含量。生物质灰含有大量营养物质(Ca、K、Mg、P、Fe),可作为钙化材料使用,影响土壤的物理和化学性质、土壤微生物活性和土壤分解,并最终提高作物生产力。在草地上和饲料生产中施用6-22 t ha-1的灰分,可提高饲料物种的生产力、牧草中豆类的比例和饲料的营养价值。

Intercropping arable crops between tree rows has proven to be a great alternative to conventional agriculture in terms of food production sustainability and climate change adaptation. However, close interactions between species in these systems sometimes yield adverse allelopathic effects. In this study, the possibility of intercropping barley and maize in the walnut orchard was investigated in terms of walnut leaf litter toxicity. Leaves from 15 and 30 years old walnut trees were used to prepare water extracts out of freshly fallen leaves and soil with leaves decomposed within. Barley and maize seeds were germinated in these extracts using between paper towels method. Fresh leaf litter extracts slightly reduced barley germination but significantly inhibited both barley and maize seedlings’ growth. The extract from older walnut tree leaves had the most severe toxic effect, and seedlings shoot was more sensitive than root for both species. A significant correlation was observed between extracts pH and seedlings lengths, suggesting the hydrogen-induced injury to the root, which consequently influenced growth. Decomposed leaf litter extract had a promotional effect on barley and maize germination and growth, which shows that appropriate walnut litter management could improve the performance of intercropped walnut systems.

Designed-enriched products have been recently one of the most interesting areas of research and innovation in the animal production and food industry. These products are considered functional foods and contain ingredients that have beneficial physiological effects on human health. Designed or enriched eggs are an important type of functional food in poultry production. Demand for functional foods in the market has been increasing in recent years. Due to the increased interest of people in buying designed products, there is a production adjustment in the poultry industry. Composition change of laying hens feed affects nutritional composition change of eggs as well as their quality preservation. This process can an effect of the change in the concentration of cholesterol and its fractions, fatty acids, and pigments in eggs. It is evident from the relevant scientific literature that designer eggs consumption can have a positive effect on human health. Therefore, the aim of this paper is to describe different concepts of designer eggs production and emphasize the health benefits of their consumption in humans.

The paper presents the results of a triennial study of the sowing system influence on the yied, grain weight per head, plant set per ha and of the grain moisture of a medium-early sunflower hybrid . Standard sowing was performed with the PSK OLT sowing machine at a row spacing amounting to 70 cm, while a twin row sowing was performed with the MaterMacc Twin Row-2 sowing machine at a row spacing of 22*48 cm. Both sowing machines were adjusted according to the ISO standard 7256/1 and 7256/2, with a high QFI index (PSK OLT: 96.32 %; MaterMacc Twin Row-2: 93.93 %). The research was conducted at the Gorjani Experimental Field on psudogley bearing the textured markings of a silty loam, with a weak acid reaction and a small amount of humus. An analysis of variance determined a statistical significance of the sowing system on the grain yield and the grain mass per sunflower head. Sowing in twin rows achieved the higher yields for all three research years : 19.59% in 2017, 19.11% in 2018, and 18.45% in 2019. Plant density was not statistically significantly affected by the sowing systems and vegetation year, but the grain moisture was statistically significantly different between the analyzed research years .

The stored-product insects are one of the major causes of losses in the stored cereals. Most of control measures still rely on a synthetic pesticide usage, but due to its negative side effects on the goods, human health, and the environment, there is an urgent need for an alternative control. A natural formulation based on the diatomaceous earth (DE) SilicoSec®, enhanced with the botanicals (essential oil lavender, corn oil, and bay leaves dust) and the silica gel was developed. The aim of the study was to test the activity of the developed formulation as a postharvest protectant of seed wheat and barley in the suppression Sitophilus oryzae (L.), Rhyzopertha dominica (F.) and Tribolium castaneum (Herbst). As a reference comparative value, the DE SilicoSec® was applied. Subsequent to the six months of storage under the simulated warehouse conditions, the formulation has completely suppressed the initial population development of all three tested insect species, both in wheat and barley. In wheat, a complete suppression was detected at the dose of 500 ppm against T. castaneum and 600 ppm against both R. dominica and S. oryzae. In barley, a complete suppression was detected at the doses of 500 ppm, 400 ppm, and 600 ppm against R. dominica, T. castaneum and S. oryzae, respectively. Conclusively, the results of this study indicate that the developed natural formulation based on the DE, botanicals, and silica gel was highly effective against the three major stored‐product insect species, providing a long-term safe storage of wheat and barley seeds.

The field trials were carried out in the Bitola and Titov Veles regions during two sunflower growing seasons (2018 and 2019) to estimate a weed control in sunflower with the soil‒applied herbicides, influenced by a prolonged and limited rainfall. Polygonum aviculare L., Solanum nigrum L., Chenopodium album L., Amaranthus retroflexus L., Portulaca oleracea L., and Echinochloa crus-galli (L.) P. Beauv. were the most dominant weeds in both regions. The efficacy of PRE-em herbicides varied among the weed species, treatments, periods of efficacy estimation, regions, and years. The overall performances of the PRE-em herbicides were correlated with weather and soil conditions. The inconsistent weather patterns between the two years of the study likely influenced the weed control. All weeds in 2018 in the Bitola region were poorly controlled (<77% and <62%, 28 and 56 days after application, respectively) due to a higher amount of rainfall (57 mm) during the 10 days of the 1st decade after herbicide application. The herbicide efficacy has only produced a marginal control of weeds in 2019 in the Titov Veles region as well (<68% and <59%, 28 and 56 days after application, respectively), due to the drought conditions observed in this region in early spring and in mid-spring. A PREem application followed by a heavy rainfall resulted in a sunflower injury in the Bitola region in 2018, ranging from 9 to 28% across the PRE-em treatments seven days after emergence. The injuries by oxyfluorfen and dimethenamid-P were more serious (24 and 28%, respectively). The sunflower achene yields for each treatment in both regions generally reflected an overall weed control and crop injury.

During cultivation, wheat is exposed to several abiotic and/or biotic stress conditions that may adversely impact the wheat yield and quality. The impact of abiotic stress caused by nitrogen deficiency and biotic stress caused by phytopathogenic fungus Fusarium culmorum on biomarkers of oxidative stress in the flag leaf of nine winter wheat varieties (Ficko, U-1, Galloper, BC Mandica, BC Opsesija, Ingenio, Isengrain, Felix, and Bezostaya-1) was analyzed in this study. Hydrogen peroxide concentration and lipid peroxidation level were measured as indicators of oxidative stress, while the antioxidant response was determined by measuring the concentration of phenolic compounds and activities of antioxidant enzymes. Wheat variety and nitrogen treatment had a significant effect on all examined biomarkers of oxidative stress in the flag leaf, while the impact of Fusarium treatment was less pronounced. The most significant impact on the measured stress biomarkers had a low nitrogen level, which mainly increased hydrogen peroxide concentration and lipid peroxidation level and decreased activities of antioxidant enzymes in most varieties. The obtained results were discussed and compared with the previous study in which biochemical analyzes were performed on the wheat spike. There was no significant strong correlation between flag leaf and spike response in the measured parameters, which, in addition to the variety-specific response, also indicates a tissue-specific antioxidant response.

Thousand kernel weight (TKW) is an important yield component trait affected by the environmental conditions. This study’s objectives were to determine an environmental variability for the TKW in 32 maize hybrids, sorted in four FAO maturity groups (FAO300, 400, 500 and 600), and to compare 12 environments in Croatia (six locations in two years) according to the joint linear regression and stability analyses across the maturity groups. In general, the effects of the environment, genotype, and their interaction (GEI) were significant. A three-factor ANOVA revealed the greatest and highly significant year effect, while the location effect was non-significant across all four FAO groups. A stability analysis did not detect any preferences with regard to the locations and trends across the FAO groups. It indicates that all locations in the Pannonian region included in this study were suitable for an evaluation of the TKW in maize genotypes belonging to all maturity groups. The TKW seems to be an appropriate yield-component trait for maize breeding due to a high heritability and linear GEI nature.

The aim of the present research was to determine the hematological and biochemical parameters of the Travnik pramenka ewes during lactation. Thirty‐six ewes in average age of 3-5 years were included in the research. They were monitored in three stages of lactation: early, medium, and late stage. The WBC and RBC, HGB concentration, HCT and MCH values increased significantly as lactation progressed, while significant decrease of MCV and MCHC was determined in blood. HCT was slightly higher in the early compared to late stage, and the MCH in the medium compared to the late stage of lactation. A significant increase in the concentrations of Ca, P, Mg, Na and Cl, as well as a decrease of the Fe concentration was determined. As lactation progressed, the concentrations of urea, total proteins, albumin, globulin and BHB increased, as well as ALT activity. Contrary, concentrations of glucose and NEFA decreased, as well as GGT activity. Obtained results may help in monitoring the health and nutritional status of Travnik ewes. The effect of lactation stage needs to be included in the model when preparing the reference values for the blood parameters of Travnik pramenka ewes, particularly for RBC profiles, energy, and protein metabolites as well as liver enzymes.

The effect of lactation stage needs to be included in the model when preparing the reference values for the blood parameters of Travnik pramenka ewes, particularly for RBC profiles, energy, and protein metabolites as well as liver enzymes.","PeriodicalId":44286,"journal":{"name":"Poljoprivreda","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46276531","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}
Croatia is the newest member of the EU Farm Accountancy Data Network (FADN). So far, no comprehensive evaluation of the national FADN system has been conducted, and this study based on a survey of staff involved and a desktop analysis was conducted to fill this gap. The three main elements of the Croatian FADN system are the National FADN Committee, the Ministry of Agriculture as Liaison Agency (LA) and the Croatian Bureau for statistics. All FADN survey activities are carried out by LA and the main burden of data collection lies with the data collectors and the farms. The system operates in accordance with relevant EU legislation and currently its main objective appears to be the fulfilment of its obligations to the FADN network. Other benefits like analysis of CAP measures etc. are not yet exploited. The main challenges are further development of quality assurance systems, the motivation of staff and farms to participate, the increased use of FADN data, and the expected changes in transformation of the FADN into the sustainability data network (FSDN). Croatia will successfully meet these challenges if it strengthens its capacity for FADN research and data analysis and establishes an effective quality assurance system.
