Sunn pests, which can cause significant yield losses on wheat and barley, are one of the pests whose population levels should be followed. Overwintering areas, which have an important place in the biology of the insect, provide an advantage in the development of biological or integrated control with entomopathogenic fungi. Entomopathogenic fungi are one of the most important control agents in reducing the population in overwintering areas. In this study, one Lecanicillium psalliotae (KK8) isolate and one Akanthomyces muscarium (DIKA11/1) isolate were identified according to morphologic and molecular data. Pathogenicity test was carried out with DIKA11/1 A. muscarium isolate. Adult insects were inoculated with a 1×10 7 conidia/ml suspension. With this current study, A. muscarium was reported for the first time on sunn pests with 87.7% mortality rate. The L. psalliotae species, which is a pathogen on other insects and sunn pests, was isolated from the sunn pests and identified from Turkey. It is thought that DIKA11/1 A. muscarium isolate can be used in the biological control of this insect and commercial formulation development studies.

This study aimed to identify the small flies which occurred in disturbingly high numbers covering the upper floors' windows of the Georgikon Campus of the Hungarian University of Agriculture and Life Sciences in the early fall of 2021. During the on-site visit, numerous specimens were collected for later identification. As a result of the species determinations, Thaumatomyia notata (Meigen, 1830) was identified. According to the employees, the mass autumn appearance of flies in that high building has been repeatedly seen over the past decades. Thaumatomyia notata is, in fact, a valuable species, of which larvae are primarily found in the soil as a predator of Pemphigus spp. root aphids

The aim of this study was to determine effect of diet-based seasonal changes on fatty acid composition of Jersey milk in mountain region of Croatia. Bulk milk samples (200 mL) were collected during total-mixed ratio (TMR)-based, intermediate and pasture-based diet. Fatty acid composition of milk was determined by gas-chromatography. We found that pasture-based diet has positive effect on fatty acid composition of Jersey milk considering human nutrition. During pasture-based diet, Jersey cows produced milk with lower ( P <0.05) saturated fatty acid and higher ( P <0.05) polyunsaturated fatty acid content. Namely, regarding individual fatty acids, milk produced during pasture-based diet had lower ( P <0.05) C16:0 and higher ( P <0.05) C18:2n-6, C18:3n-6 and conjugated linoleic acid (CLA) content than milk produced during TMR and intermediate diet. Milk produced during pasture-based diet can be valuable source of health-beneficial PUFA in diet.

The research of sanitary status and virus presence was conducted on three native Croatian grapevine varieties (Kujudžuša bijela, Zlatarica vrgorska and Trnjak crni) that are grown in Dalmatia region. The investigation was done on 492 vines from 31 vineyards. Vines were tested by ELISA (Enzyme-Linked Immunosorbent Assay) on four main economic viruses: arabis mosaic virus (ArMV), grapevine fanleaf virus (GFLV), grapevine leafroll-associated virus 1 and 3 (GLRaV–1, GLRaV-3) as a first step in clonal selection of these rare native grapevine varieties. Altogether, 40 vines were free of all tested viruses. The research confirms high rate of virus infection and eroded sanitary status of all investigated varieties. The above indicates necessity of implementation clonal and sanitary selection programme.

Due to the lack of reliable longitudinal data, farm income and income trends haven’t been much analysed in Croatia, specifically among horticultural producers. Based on Croatian Farm Accountancy Data Network (FADN), the goal of this paper is to research the income of all farms in comparison to horticultural farms. In addition, paper tests farm’s eligibility for Income Stabilization Tool (IST) compensation. Objectives of the paper are: (1) analysis of farm income in the period 2014-2017 for all farms and specifically for horticultural farms, and (2) analyse how many horticultural farms have potential for IST compensation. For the second objective, we prepared scenarios of annual income drop of 10%, 20%, and 30% of the three-year average income. Scenarios are shown for groups wine, orchard, and olive farms (calculated group index) and for individual farms (calculated farm index). Results show that horticultural farms’ income is on the similar level to the data for all the farms in FADN. The group index calculation compared to farm index income calculation shows a higher number of farms eligible for IST. The paper might serve as a basis for the introduction of IST in Croatian agriculture.

The amount of biomass produced by various native species of genus Lupinus (L.) growing in Mexico ranges from 2.9-8.2 Mg/ha of dry matter, which can add up to 200 kg/ha of N to soil as green manure. However, information is scarce on the decomposition and mineralisation this biomass in the soil. The above-ground decomposition and N mineralisation of Lupinus mexicanus Cerv. ex Lag. and Lupinus rotundiflorus M.E. Jones species from Mexico using fine-mesh litter bags was evaluated. Litter bags containing 5 g of above-ground air-dried biomass at the vegetative and flowering stages were buried at a depth of 20 cm. Were dug up every 3 weeks over the course of 4 months, dried and re-weighed to determine the lost mass and total N by the Kjeldahl method. The largest decrease in residue mass occurred during the first 3 weeks of incubation. However, the lost mass was higher in younger green manure (75 days old) than in older plants (85 days old) after 18 weeks of exposure in the field. It was found that 60-75% of the total N in the plant material was released in the first 6 weeks. In L. rotundiflorus green manure, it was found that 79.14% of the initial N in the vegetative stage and 77.6% of N in the flowering stage was released 18 weeks after litter bag installation, whereas L. mexicanus were 74.6% and 74.7%, respectively. It was found that both decomposition and N mineralisation occurred quickly in the green

The usage of plant growth-promoting bacteria (PGPB) in mitigation of harmful effects of lead (Pb) toxicity in plants and bioremediation of it from soils is a sustainable, effective and low-cost strategy. The experiment was laid out to investigate the role of PGPB on morphological and physiological growth, root system architecture and nodulation of lentil under Pb stress. The experiment was conducted according to completely randomized factorial design with four replications at the laboratory of the Field Crops Department, Siirt University, Siirt in 2022. The four Pb levels and three bacterial inoculations were used in the experiment. Plant height, seedling fresh weight, root fresh weight, seedling dry weight, root dry weight, total chlorophyll content, taproot length, number of lateral roots, total root length and number of nodule varied between 15.7-25.9 cm, 0.123-0.235 g, 0.019-0.092 g, 0.0104-0.0326 g, 0.0076-0.0146 g, 27.9-47.2%, 8.9-19.2 cm, 4.00-14.67, 17.6-44.8 cm and 1.37-10.63, respectively. Bio-priming with PGPB containing 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase activity increased dry matter accumulation up to 56.1% and 22.9% in shoots and roots, respectively. Chlorophyll content enhanced up to 17.9% compared with control application. Besides, root system architecture and nodule formation were improved by bio-priming both under stress and non-stress conditions. Bio-priming with PGPB may be a sustainable solution to mitigate

The aim of the experiment was to assess the content of N-corrected apparent metabolisable energy (AMEn) in dried Sea buckthorn berries (SB) when fed to Ross 308 broiler chickens. Two experimental diets (basal and basal + 12 g/kg dried and milled SB berries) were fed to an equal number of replicated pens (n=8; two birds in each) from 7 to 21d age, following randomisation. The basal diet was formulated to meet breeder’s recommendations. The inclusion of dried SB berries at 12 g/kg diet, did not significantly ( P >0.05) affect broiler chicken growth performance, dietary nutrient availability or AMEn. Using the substitution method, it was found that the AMEn of the dried SB berries was 14.29 MJ/ kg DM. Although relatively high in AMEn, the absence of starch in SB berries, suggests SB berries are not a suitable substitute for cereals in poultry diets, but further research on their health benefits as a minor supplement for poultry diets is warranted.
本试验旨在评价罗斯308肉鸡饲喂沙棘干莓(SB)时氮校正表观代谢能(AMEn)的含量。饲喂2种试验饲粮，分别为基础饲粮和基础饲粮+ 12 g/kg干枸杞和磨粉枸杞，饲喂相同数量的重复栏(n=8;每组2只，年龄从7岁到21岁。基础日粮的配制符合育种者的建议。12 g/kg饲粮中添加干SB浆果对肉鸡生长性能、饲粮营养物质利用率和AMEn均无显著影响(P < 0.05)。采用替代法，发现干枸杞的AMEn为14.29 MJ/ kg DM，虽然AMEn相对较高，但由于枸杞中淀粉含量的缺失，表明枸杞不适合作为家禽日粮中谷物的替代品，但其作为家禽日粮中少量补充物的健康益处有待进一步研究。
