"The purpose of this study was to improve conventional agricultural technologies in soybean crop to ensure a higher yield and reduced environmental impact under climate conditions specific for the Transylvanian Plain. For the experimental design a three-factorial experiment was set up (tillage x fertilization x plant protection products). Factor interaction was evaluated using formula AxBxC-R:4x4x4-3 to highlight the benefits of the practices. This study examined yield crops and size of the soybean plants in an effort to identify best practices. Yield was highly increased in conventional soil tillage system (3420 kg/ha), whereas for the minimum soil tillage system and for direct sowing there were no significant difference 2755-2995 kg/ha and 2605 kg/ha, respectively. Crop performance in terms of yield was highly influenced by the soil tillage system (57.5%), followed by plant protection treatments (22.9%) and fertilization (11.8%). Fertilization with N40P40 + gulle + green fertilizer ensured the highest soybean production (3132 kg/ha). Plant protection treatments during vegetation determined significant yield increases, with high influence of insecticides and a cummulative effect when both fungicides and insecticides were used (3193 kg/ha). Highest size of plants was registered in conventional soil tillage system. Overall crop protection treatments during vegetation (insecticide + fungicide) triggered not significant increases in plant size, except Teo TD soybean cultivar."

The regional agroecological conditions, specific to the Transylvanian Plain, are favorable to soybean crops, but microclimate changes related to global warming have imposed the need for agrotechnical adaptive measures in order to maintain the level of soybean yield. In this study, we consider the effect of two soil tillage systems, the seeding rate, as well as the fertilizer dosage and time of application on the yield and quality of soybean crops. A multifactorial experiment was carried out through the A × B × C × D − R: 3 × 2 × 3 × 3 − 2 formula, where A represents the year (a1, 2017; a2, 2018; and a3, 2019); B represents the soil tillage system (b1, conventional tillage with mouldboard plough; b2, reduced tillage with chisel cultivator); C represents the fertilizer variants (c1, unfertilized; c2, one single rate of fertilization: 40 kg ha−1 of nitrogen + 40 kg ha−1 of phosphorus; and c3, two rates of fertilization: 40 kg ha−1 of nitrogen + 40 kg ha−1 of phosphorus (at sowing) + 46 kg ha−1 of nitrogen at V3 stage); D represents the seeding rate (1 = 45 germinating grains (gg) m−2; d2 = 55 gg m−2; and d3 = 65 gg m−2); and R represents the replicates (r1 = the first and r2 = the second). Tillage had no effect, the climate specific of the years and fertilization affected the yield and the quality parameters. Regarding the soybean yield, it reacted favorably to a higher seeding rate (55–65 gg m−2) and two rates of fertilization. The qualitative characteristics of soybeans are affected by the fertilization rates applied to the crop, which influence the protein and fiber content in the soybean grains. Higher values of protein content were recorded with a reduced tillage system, i.e., 38.90 g kg−1 DM in the variant with one single rate of fertilization at a seeding rate of 45 gg per m−2 and 38.72 g kg−1 DM in the variant with two fertilizations at a seeding rate of 65 gg m−2.

Abstract. With the implementation of integrated pest management in the European Union, growers are obliged to manage pests in a manner that minimizes health and environmental risks due to the use of plant protection products. Among other approaches, this goal can be achieved by optimizing spray application techniques. As an alternative to the predominantly used handheld equipment, such as spray guns, spray boom systems might substantially improve spray application, and thus crop protection management, in greenhouses. The aim of this proof-of-concept study was to compare different spray configurations in a spray cabin designed to spray ornamental potted plants that are moving on a conveyor belt. Seven different spray configurations were examined for optimal spray deposition in two crops (azalea and ivy) using mineral chelate tracers. The deposition tests showed that the presented prototype can satisfactorily spray potted plants up to a height of 25 cm including the pot height. The best spray deposition was found with two flat-fan nozzles oriented 35° upward, spraying at 1.0 bar and an application rate of 1047 L ha-1. This configuration increased deposition on the underside of the leaves and at the middle foliage layer compared to the other configurations that were evaluated. The spray cabin with a band spray setting has potential to mitigate the use of plant protection products and achieve a more efficient spray application compared to traditional handheld techniques and broadcast spray boom techniques. Keywords: Crop protection, Integrated pest management, Nozzle type, Spray deposition.

In Italy, wine production is considered a sector of excellence, where the wines’ appreciable sensory features are favored by environmental factors, including weather and climate conditions, which benefit territories with a specific vocation. The whole chain involves many economic and agri-food sector operators, and requires an in-depth assessment of specific risks for identifying critical points, keeping the entire production process under control, and ensuring product traceability. This article describes the results of a pilot study conducted in the Prosecco DOCG (Designations of Controlled and Guaranteed Origin) area, concerning the detection of residues of plant protection products in fifty wine bottles. Although considerably below the maximum residue levels, all the samples tested were positive, ranging from two to five active substances detected in each sample. In addition to the provisions of the European Community legislation, this paper critically evaluates some best practices models that are already used by the Wine Federations of Italy, with the aim of identifying advantages of and areas for improvement in production methods, applicable to raw materials reception, rasping, storage, and bottling phases, in order to guarantee product safety and quality.

The field experiments with barley of multiserial Vakula variety were conducted on gray forest soil of Kama region of theRepublic of Tatarstan. This experiment was carried out to identify the responsiveness of barley for fertilizers, methods of the basic soil cultivation and plant protection products. On average over three years of our research, the highest yield of barley (3.95 tons per hectare) was obtained in the flattered soil tillage and carrying out the calculated fertilizernorm in the way, when we used the seed protectant Stinger for pre- treatment of the soil. The yield was a little lower (3.88 tons per hectare), when we used Binoram for pre-sowing seed treatment, Albit was in the third place (3.80 tons per hectare), the fourth - Rizoagrin (3.65 tons per hectare), and the fifth - control (3.42 tons per hectare). The lowest barley yield (2.46 tons per hectare) were obtained on the background when not fertilized subsoiling tillage without the use of plant protection products. The use of seeds for incrustation, treated by Stinger chemical fungicide, increased the yield to 4.0 centner per hectare, compared with the control. When we used moldboard plowing, the yield declined in control to 4.7 centner per hectare and at fertilizered background to 4.9 centner per hectare, and at KSN soil treatment to3-5.3 centner per hectare. In arid 2010 the highest barley harvest was obtained at KSN-3 soil treating, on the second place is subsurface treatment and the third is plowing. Modern energy-saving methods of the basic soil cultivation, treating the calculated norms of fertilizers and use of plant protection products contribute to the production of planned productivity, saving fuel and lubricants, but they are unable to maintain phytosanitary conditions in barley fields within economic threshold. Taking inro account above-mentioned and the current state of agriculture in the steppe of the Volga region, it is necessary to alternate basic soil treatment methods, application of calculated norms of fertilizers and use protectants and biofungicides for pre-sowing treatment, considering fitoekzamination of seeds.

SUMMARYField experiments were conducted between 2009 and 2011 in Ireland to compare the effects of soil tillage systems on the grain yield, nitrogen use efficiency (NUE) and nitrogen (N) uptake patterns of spring barley (Hordeum vulgare) in a cool Atlantic climate. The four tillage treatments comprised conventional tillage in spring (CT), reduced tillage in autumn (RT A), reduced tillage in spring (RT S) and reduced tillage in autumn and spring (RT A+S). Each tillage system was evaluated with five levels of fertilizer N (0, 75, 105, 135 and 165 kg N/ha). Grain yield varied between years but CT had a significantly higher mean yield over the three years than the RT systems. There was no significant difference between the three RT systems. Tillage system had no significant effect on the grain yield response to fertilizer N. As a result of the higher yields achieved, the CT system had a higher NUE than the RT systems at all N rates. There was no significant difference in NUE between the three RT systems. Conventional tillage had significantly higher nitrogen uptake efficiency (NUpE) than RT A and a significantly higher nitrogen utilization efficiency (NUtE) than all three RT systems. Crop N uptake followed a similar pattern each year. Large amounts of N were accumulated during the vegetative growth stages while N was lost after anthesis. Increased N rates had a positive effect on N uptake in the early growth stages but tended to promote N loss later in the season. The CT system had the highest N uptake in the initial growth stages but its rate of uptake diminished at a faster rate than the RT systems as the season progressed. Tillage system had an inconsistent effect on crop N content during the later growth stages. On the basis of these results it is concluded that the use of non-inversion tillage systems for spring barley establishment in a cool oceanic climate remains challenging and in certain conditions may result in a reduction in NUE and lower and more variable grain yields than conventional plough-based systems.

<p>Based on a 3-year field experiment conducted on medium heavy mixed rendzina soil, the present study evaluated the effect of chemical plant protection on the species composition, number and air-dry weight of weeds infesting crops of winter spelt wheat cultivars (‘Frankenkorn’, ‘Badengold’, ‘Schwaben- speltz’, and ‘Oberkulmer Rotkorn’) sown under ploughing and ploughless tillage systems. Ploughing tillage involved skim- ming done after harvest of the previous crop and pre-sowing ploughing, while in the ploughless tillage system ploughing was replaced with cultivating. Chemical weed control included the application of the herbicides Mustang 306 SE and Attribut 70 WG. Plots where the herbicides were not used were the control treatment. On average, from 21 to 30 weed species colonised the winter spelt wheat crops compared. <em>Galium aparine </em>and <em>Apera spica-venti </em>occurred in greatest numbers and their percentage in the total number of weeds was estimated at 26–35% and 17–25%, respectively. The cultivar ‘Frankenkorn’ was the least weed-infested. Both the number of weeds in the crop of this cultivar and their above-ground dry weight were lower compared to the other cultivars. The use of reduced tillage significantly increased the air-dry weight of weeds compared to ploughing tillage. Nevertheless, it should be indicated under ploughless tillage conditions the application of chemical crop protection reduced weed biomass by 59% compared to the control treatments without crop protection.</p>

In the past decades, the scientific quality of biomedical studies has been hierarchically depicted in the well-known pyramid of evidence-based medicine (EBM), with higher and higher levels of evidence moving from the base to the top. Such an approach is missing in the modern crop protection and, therefore, we introduce, for the first time, this novel concept of evidence-based phytoiatry in this field. This editorial is not a guideline on plant protection products (PPP) registration, but rather a scientific and technical support for researchers involved in the general area of plant pathology, providing them with evidence-based information useful to design critically new studies.

Abstract Reduction of copper-based fungicides with the final aim of phasing out has a high priority in European policy as well as in organic agriculture. Our survey aims at providing an overview of the current use of copper-based plant protection products in European organic agriculture and the need for alternatives to allow policy makers to develop strategies for a complete phasing out. Due to a lack of centralized databases on pesticide use, our survey combines expert knowledge on permitted and real copper use per crop and country with statistics on organic area. In the 12 surveyed countries, covering together 83% of the European organically managed horticultural area, we calculated approximately 3258 t copper metal per year are consumed by organic agriculture, equalling to 53% of the permitted annual dosage. This amount is split between olives (1263 t y-1, 39%), grapevine (990t y-1, 30%), and almonds (317 t y-1, 10%), followed by other crops with much smaller annual uses (<80 t y-1). Potato, usually considered a highly demanding plant for copper inputs, only uses 39 t y-1 of copper per year. In 56% of the allowed cases (countries × crops), farmers use less than half of the allowed amount, and in 27% less than a quarter, with some variability between countries. Considering the large volumes of copper used annually, replacement of copper seems only feasible if all preventive strategies from the crop protection pyramid are fully implemented and several affordable alternative plant protection products are successfully brought to the market.

Abstract The paper presents the yield results obtained in 2017 for the corn crop grown in the soil and climate conditions of Southern Romania (Calarasi county). The purpose of the research was to analyze the behavior and yield of a range of corn hybrids from different FAO groups: DKC 4590 (FAO 350), PP9911 (FAO 410) and Olt (FAO 430) under different soil tillage systems. The conventional tillage system applied was plowing at 20 and 30 cm, while scarifying at 30 and 40 cm and Tiger 3 MT at 20 and 30 cm were used for the minimum tillage system. The average yield of the three hybrids analyzed was 8,130.3 kg/ha in the conventional tillage system (plowing at 20 and 30 cm) with mechanical weeding, while for the conventional tillage system without mechanical weeding the yield was 7,682.2 kg/ha. The minimum tillage variants (scarifying and Tiger 3 MT) recorded an average yield of 6,746.4 kg/ha when mechanical weeding was applied and 6,474.9 kg/ha for the variants without mechanical weeding. Regarding the degree of weeding by tillage system, in the conventional tillage system (plowing at 20 and 30 cm) with mechanical weeding the number of weeds was 4.2 plants/m2 and 9.3 plants/m2 for the variants without mechanical weeding. The minimum tillage variants (scarifying and Tiger 3 MT) recorded 12.8 weeds/m2 when mechanical weeding was applied and 16.2 weeds/m2 for the variants without mechanical weeding.

To increase the export of grain fat-and-oil products is required the improvement financing scientific research mechanism, since the effectiveness of all links in the value chain depends on the effectiveness of the selection. The mechanisms of value extraction in the implementation of breeding achievements include the use of hybrids, a combination of unique genotypes and production systems. The first component reduces the seeds portion of household use, excluding the royalty collection. From 57% to 79% of listed rapeseed entries in National Registers of nine countries are hybrids. The combination of unique traits in one genotype proved to be effective in the genetically modified (GM) crops, e.a. in "stacks" genotypes with two genes from alien species. The production system means technology with herbicide and seeds package offer. Based on genetic engineering, glufosinate ammonium, glyphosate and bromoxynil resistant seeds are bred and commercialized worldwide; 24% of rapeseed acreage out of the 39 million hectares are GM. Triazine, imidazolinone and sulfonylureas resistance is developed by classical breeding methods. There are three global leaders nowadays: Bayer CS, acquired Monsanto, with total seed sales $ 10.6 billion, Corteva Agriscience (agricultural Department of DowDuPont) ($ 7.3 billion) and Syngenta (acquired by ChemChina) ($ 2.3 billion). Mergers and acquisitions of global players in the pesticide and seed markets reshape the market of agricultural technologies as a set of innovative methods, databases and knowledge for the portfolio development with a package offer of plant protection products, seeds and digital solutions.
