In modern agriculture, on large-scale farms using monoculture, reduced tillage and intense chemical protection, the phenomenon of herbicide resistance in weeds is the cause of ecological and economic losses. More and more attempts are made to answer the question about the profitability of reducing agrotechnical treatments and intensifying chemical methods of weed control with a simultaneous intensification of the problem of herbicide resistance in weeds occurring in winter wheat crops, which dominates the structure of cereal sowing in Poland. The main objective of the study was to evaluate the costs of weed control for winter wheat cultivation on large-scale farms where there was no problem of weed resistance and on farms where resistant biotypes were identified. The research was based on a survey conducted among owners of farms cultivating winter wheat in 2019. The collected data were elaborated using basic methods of descriptive statistics and economic analysis. Based on the research results, it was found that with an increase in the area of farms, reduced tillage and monoculture are used more frequently than conventional tillage and crop rotation. At the same time, the commonly used chemical weed control methods are more frequently applied than mechanical ones. Economic efficiency indicators for winter wheat protection against weeds indicate a decrease in this efficiency with an increase in farm size. This is because the larger the farms, the more frequently the occurrence of resistant weed biotypes, which was confirmed by laboratory tests, and farmers more often assumed that such a problem occurred on their farms

Seed treatments help reduce the pathogen load and thus improve the condition of plants from their earliest developmental stages, but they can have impacts beyond their basic fungicide protection role. In this study, we investigated how seven spring barley seed treatments affected the plants’ physiological state. The tested seed treatments differed significantly in their impacts on the vigor parameters of barley seeds and on the physiological state of seedlings under drought stress and after regeneration. Seed treatments based on substances from the succinate-dehydrogenase-inhibitors (SDHI) group did not cause inhibition of seedling growth and also display by the highest vigor index values. Using the analysis of photosynthesis-related parameters, we showed that seed treatments from the SDHI group provided a superior tolerance of the imposed drought in spring barley than other treatments. In addition to protection against abiotic stress, SDHI treatments also rendered a higher efficiency of photochemical reactions in the treated plants.

The aim of this study was to characterize extracts from the leaves of Ginkgo biloba L. from selected Slovakian localities in terms of the content of bioactive constituents, antioxidants and their antimicrobial properties. The results indicated that the content of antioxidants was sample-specific, and this specificity was statistically significant. Ginkgo biloba L. from the locality of Košice had the best activity determined by the free radical scavenging activity (DPPH) (1.545 mg Trolox equivalent antioxidant capacity (TEAC)/g fresh matter (FM)) as well as the molybdenum-reducing antioxidant power (35.485 mg TEAC/g FM) methods. The highest content of total polyphenols (2.803 mg gallic acid equivalent (GAE)/g FM) and flavonoids (4.649 μg quercetin equivalent (QE)/g FM) was also detected in this sample. All samples of G. biloba leaf extracts showed significant antimicrobial activity against one or more of the examined bacterial species, and Staphylococcus aureus subsp. aureus CCM 2461 was found to be the most susceptible (minimal inhibition concentration MIC50 and MIC90 values of 64.2 and 72.2 µg/mL, respectively). Based on the results it was concluded that Ginkgo biloba L. extracts can be used as antimicrobial and antioxidant additives. Selected miRNA-based molecular markers were used to examine the environmental adaptability of Ginkgo biloba L. An almost-complete genotype clustering pattern based on locality was determined in the analysis that involved a species-specific gb-miR5261 marker. Morphologically specific exemplar, cv. Ohatsuki, was excluded.

Integrated pest management (IPM), a worldwide agricultural strategy, contains methods to control or manage agricultural pests and diseases in a more efficient way, and consequently, to obtain better quality raw materials for food production. The engagement and practice of farmers play a key role in the success of this strategy. Since January 1, 2014, Poland and other European Union countries have been obligated to apply the principles of IPM. This paper shows the results of surveys conducted in 280 randomly selected farms the year before and the year following mandatory IPM implementation. The aim of this study was to gather information about farmers’ knowledge of IPM and the most commonly used plant protection methods. Our results show that law regulations do not significantly change agricultural practice. Among the non-chemical methods farmers most often comply with are: implementing the agrochemical calendar, sowing healthy material, destroying volunteer plants, rotating crop, applying balanced fertilizer, plowing stubble and preventing excess nitrogen. Integrated plant protection is not possible without proper knowledge of diseases. This factor needs improvement in Poland. The average Polish farmer lacks the knowledge about basic cereal diseases such as powdery mildew or brown rust, though larger farm operators tend to be more knowledgeable. The results of this survey demonstrate the necessity to provide informative farmer training campaigns to promote on-farm application of IPM and to improve the knowledge of disease issues.

The influence of stress factors on the plant can, on the one hand, lead to worse functioning of the plant and loss of its crop, but on the other, it can have a positive effect on the metabolism of compounds with documented biological activity. In this study, the effect of light and drought intensity on photosynthetic activity and physiological status of two barley varieties, as well as the antimicrobial, antioxidant properties and profile of polyphenolic compounds of green barley were analysed. It was shown that under the conditions of water shortage, the KWS Olof variety showed a smaller decrease in CO2 assimilation and transpiration and higher values of these parameters at both light intensities. Only in the KWS Olof variety increased stress as a result of increased light intensity. It has also been shown that both the intensity of radiation and drought-related stress have a significant impact on the profile of polyphenolic compounds from green barley, without a simple relationship between the impact of stress factors on the content of polyphenols. Changes in the profile of polyphenolic compounds augmented the antioxidant and antimicrobial activity of the material. This, in turn, proposes the possibility of reducing the applied doses of herbal material thanks to a greater content of active substances in extracts obtained from the plants used to produce medicinal preparations.

A reduction in biodiversity due to farming operations has been broadly reported. As a solution, policy makers in the European Union have introduced several programs in recent years to enhance biodiversity on farms but these have met with only limited success. One of the main reasons for this lack of success is that the experience, knowledge and attitudes of farmers are not taken into account when biodiversity conservation programs are formulated. Farmers’ opinions must be taken into consideration in the creation of future programs, which should also include an assessment by the farmers of the value of the nature of their farms. In this study, farmers were asked to express their opinion on the attractiveness of their farm in relation to pollinators, game, birds, amphibians, reptiles, rodents and non-crop (wild) plants. Data were then analysed using a novel method in which each farm was assigned to one of four categories. High nature-value farms contained more natural features in the landscape, such as individual trees or ponds. Socio-economic factors, such as gender, also influenced the farm assessments; female farmers were more critical compared to their male counterparts. The establishment of field margins or watercourse by the farmers significantly increased the possibility that the farm would be classified as attractive.

Pollinators provide vital ecosystem services across croplands, yet simultaneously they are influenced by agricultural practices. Nevertheless, only a few studies have explored the potential interactions between soil fertilisers and pollinators. The aim of the current study, which was carried out in Poland in 2015, was to investigate the effect of different fertiliser regimes on bumblebee flower visitation rate and seed yield in crops of the field bean (Vicia faba L.). Our results show that the number of bumblebee visits may be affected by the choice of crop fertiliser. We detected differences in bumblebee number between fertiliser treatments. The organic fertiliser (manure) treatment resulted in the highest bumblebee visitation, although this did not differ significantly from NP, no fertiliser and NK treatments. On the other hand, we observed lower numbers of bumblebees on field bean plots treated with N, NPK, and PK inorganic fertilisers. Manure application also boosted plant height and resulted in a high yield similar to other balanced fertilisers (NPK and PK). Therefore, manure was the only fertiliser that resulted in a high field bean yield and at the same time attracted the main pollinators of the crop. Thus, we suggest that appropriate management practices influence both plant growth and also pollination services and we show that modern agriculture can make compromise between effectiveness and nature conservation.

The negative impact on the environment caused by intensive agriculture has been extensively discussed for years. In particular, excessive nitrogen application has been associated with biodiversity loss. Many studies have shown the potential to reduce the use of nitrogen without any impact on crop yield. Maintaining crop yield has been the goal, whereas crop quality has not been considered. In this paper, we investigate the effect of the level of soil organic carbon (SOC) and nitrogen fertiliser application on winter wheat (Triticum aestivum) yield and its quality. We show that the absence of nitrogen fertiliser decreased both yield and quality parameters of cereal grain. Quality parameters, such as protein and gluten contents, zeleny value, falling number and hardness were strongly positively influenced by nitrogen fertiliser application. The SOC level had no significant effect on these grain quality parameters. As a result, in the absence of nitrogen fertiliser, grain was not suitable for baking bread. We recommend that in the debate on the potential to limit the use of nitrogen in agricultural production, its impact on grain quality should be taken into consideration, especially at low levels of SOC.

Potato Solanum tuberosum is one of the world’s four most important crops. Its cultivation is steadily increasing in response to the need to feed a growing world population. The yield of potato is influenced inter alia by both climate and pests. The main defoliator pest of potato is Colorado potato beetle Leptinotarsa decemlineata. Using data from a long-term experiment (1958–2013) in western Poland, we show that increasing temperature has affected the trophic relationship between potato and Colorado potato beetle. The planting, leafing, flowering and harvest dates for potato were advanced, after controlling for different cultivars, by 2.00 days, 3.04 days, 3.80 days and 3.42 days respectively for every 1 °C increase in temperature. In contrast, first treatment against Colorado potato beetle advanced by 4.66 days for every 1 °C increase in temperature, and, furthermore, the number of treatments against the beetle increased by 0.204 per 1 °C increase in temperature. This suggests that the beetle responds faster to increasing temperature than the plant does, but both parts of the system are probably greatly modified by farming practices. La papa, Solanum tuberosum, es uno de los cuatro cultivos más importantes del mundo. Su cultivo está aumentando de manera estable en respuesta a la necesidad de alimentación a una población mundial en crecimiento. El rendimiento de la papa es influenciado, inter alia, por ambos, clima y plagas. La principal plaga defoliadora de la papa es el escarabajo de Colorado Leptinotarsa decemlineata. Utilizando datos de un experimento a largo plazo (1958–2013) en el oeste de Polonia, mostramos que el aumento de temperatura ha afectado la relación trófica entre la papa y el escarabajo de Colorado. Se adelantaron las fechas de siembra, fase vegetativa, la floración y cosecha de la papa, después del control para diferentes variedades, por 2.00, 3.04, 3.80, y 3.42 días, respectivamente, por cada incremento de 1 °C de temperatura. En contraste, el primer tratamiento contra el escarabajo de Colorado adelantó 4.66 días por cada 1 °C de aumento en la temperatura, y aún más, el número de tratamientos contra el escarabajo aumentó 0.204 por 1 °C de aumento en la temperatura. Esto sugiere que el escarabajo responde más rápido al aumento de temperatura que la planta, pero ambas partes del sistema son probablemente mayormente modificadas por las prácticas culturales.

Common Agricultural Policy (CAP) reform in the European Union introduced a new element: greening. The aim of greening is to support the environment and create non-productive value in agriculture. The main element of greening is the Ecological Focus Area (EFA) meaning that a portion of farmland area has to be designed for environmental purposes. This article consists of an evaluatation of greening and its elements in the first year CAP reform has come into force. Surveys were used as a tool to gather information about farm characteristics, ways to meet greening requirements as well as the opinions of farmers as to changes in direct subsidies and greening obligations. The research was conducted in 2015 directly interviewing 290 farmers from the whole of Poland. The farmers interviewed lived in different parts of the country and had different size farms. Data was prepared with the use of spreadsheets and were analysed using the R statistical program and the “gmodel” and “vcd” statistical packages were used during the calculations. Polish farmers are against greening. Greening does not significantly change the way farmers run their farms. They choose the cheapest options of EFA which are usually not the best for the environment. Furthermore, farmers have to bear the cost of introducing the new elements themselves. Despite a high number of environmental and agricultural advantages offered by new farming methods, crop rotation and after-crop sowing duty, CAP reform is assessed in a negative light. As a result of negative opinions held by farmers due to the lack of subsidies, farmers may not continue greening practices in the future.

The study of the phenology of crops, although quite popular, has limitations, mainly because of frequent changes to crop varieties and management practices. Here, we present data on the phenology and yield of winter rye in western Poland collected between 1957 and 2012 from a long-term field experiment. Data were examined for trends through time and compared to climatological factors using regression analysis. Both annual air temperature and precipitation increased during the study period, equivalent to 2 °C and 186 mm, respectively, over the 52-year period for which met data were available. We detected significant delays in sowing date and recently in emergence, but significant advances were apparent in full flowering date equivalent to 4 days/decade. Yield and plant density experienced a step like change in 1986; yield increasing by ca. 70 % and plant density increasing by ca. 50 %, almost coinciding with a similar change in annual mean temperature, but most likely caused by a changed seed rate and use of herbicides. Future climate change is expected to have a greater impact on this crop, but farmers may be able to adapt to these changes by modifying water regimes, using new machinery and sowing new rye varieties.

The field experiment was carried out in 2010–2012 at the Dłoń Agricultural Research Station, the Poznań University of Life Sciences, Poland. The study was designed to evaluate the degree of infection by powdery mildew, brown rust, and septoria leaf blotch in 61 spring wheat genotypes differing in their resistance to Fusarium ssp.The vast majority of spring wheat genotypes in the collection of gene resources in the USA defined as resistant to Fusarium ssp. confirmed their resistance under Polish climatic conditions. The B .graminis infection rate of genotypes that are considered to be resistant to Fusarium head blight was high. The resistance ranged from 7 for Sumai 3 (PL2) up to 8.8 for Ning 8331 (in a 9-point scale). Most of the genotypes (56.5%) were infected by Puccinia recondita at a level of 1–3 (in a 9-point scale). The genotypes of Sumai 3 exhibited high resistance to septoria leaf blotch, amounting to 1–2 in a 9-point scale; the resistance of Frontana ranged from 1 to 3.5, while the genotypes of Ning were infected by Mycosphaerella graminicola at 5–6.

The experiments were conducted in 2001−2003 at the Experimental Station in Zlotniki of the Agricultural University of Poznan (Poland). The impact of different fungicidal protection programs on occurrence and incidence of fungal diseases on leaf and ear as well as of diseases on stem base and roots of winter wheat was determined. Infections on stem base and roots were mostly caused by Fusarium spp. and Gaeumannomyces graminis. Seed treatment with Latitude 125 FS reduced significantly take-all of winter wheat in comparison with the standard treatment (Raxil 060 FS). However, the seed treatments lowered only slightly the incidence of brown foot rot. The applied complex chemical protection program of winter wheat reduced successfully the infection of leaves and ears by fungal diseases.
