The aim this review paper to present antioxidant properties selected plant raw materials extracts, which are useful diabetes. Antioxidants may influence radical processes individuals with Antioxidative diabetes: knowledge about antioxidants garlic, cinnamon, juniper fruits, rowan white mulberry herb, nettle rut sage dandelion,...

Human activity causes changes in habitat conditions. Where conditions have been significantly altered by human activities, novel ecosystems emerge. This paper aims to analyse ecosystem parameters, particularly relation biodiversity and restoration law. It presents the role of functioning their significance within urban-industrial landscapes. Based on extensive literature reviews, that these a subject scientific interest for many years. However, comprehensive knowledge still needs be...

Abstract Aim In the current Anthropocene, many ecosystems are being simultaneously invaded by multiple alien species. Some of these invasive species become more dominant and have greater environmental impacts than others. If two potentially invade same area, combined impact has been reported to be either (a) domination one species, that is, competitive dominance invader, or (b) invasion meltdown, where is much greater, a synergistic effect. We studied effects plant known strongly decrease...

The need for sustainable development in the context of pesticide use has been recognized by European Union. “Farm to Fork Strategy” indicates a goal 50% reduction 2030. To address this challenge, we used concept ionic liquids modify known resistance inducers, i.e., group substances whose action is indicated as an alternative fungicides. A new, patented substance developed us, which choline 3,5-dichlorosalicylate, tested its sugar beet cultivation with aim controlling Cercospora leaf spot...

Biostimulants are gaining more and attention in modern agriculture. As follows from the definition, their role is aimed at influencing plant’s metabolism, which results increasing quantitative qualitative parameters describing yield. Significant should be paid to biostimulants content of health-promoting substances contained plants. Treatments with properly incorporated into existing plant protection schemes, which, course, requires detailed research this area. However, reliable on active...

Abstract Efficient nutrient use is critical to ensure economical crop production while minimizing the impact of excessive applications on environment. Nitrogen (N) a key component agricultural production, both as an input support and waste product livestock production. Increasing concern for future sustainability preservation natural resource base has led development budgets indicators policy instruments management. Nutrient N have been developed by Organization Economic Co-operation...

A two-factor field experiment using sugar beet was conducted in 2016–2018 at Sokołowo Poland (ϕ 53°5′16.05″ N, λ 19°6′21.07″ E), a strip-plot arrangement with four replicates. Strip-till (ST) compared to conventional tillage (CT) commercial varieties (Alegra, Armesa, Contenta, Julius). In each study year, the established on lessivé soils developed from heavy loamy sand. The soil rich available macronutrients, while its reaction neutral. plant density, yield, roots quality, and technological...

This study was conducted in 2007-2010, on a farm near Œrem (south of Poznan, Poland). A field experiment set up randomized block design with four replications for each combination tested. The effects differentiated rates phosphorous and potassium applied together fixed level nitrogen magnesium fertilization were investigated. During the experiment, winter wheat grain yields high significantly different between both fertilizer treatments when compared control. Correlation analysis...

A strict field experiment with maize was carried out in the years 2009–2011 at Experimental Station of Poznań University Life Sciences. The impact mineral fertilization levels on nutritional status plants an early development stage 5–6 leaves (BBCH 15/16) assessed, as well possibility using biomass and current state nutrient supply to predict grain yield. adopted assumptions were verified basis experiments nine variants two varieties (EURALIS Semences, Lescar, France) (ES Palazzo ES Paroli...

The efficient use of phosphorus (P) is a main task in sustainable agriculture. In pot and field experiments, the effects green fertilization with catch crops P supply organic inorganic fertilizers on plant soil parameters were investigated P‐poor loamy sand. For experiment, sown September remained plots until next spring. As crops, oilseed rape (Brassica napus), spring barley (Hordeum vulgare), wheat (Triticum aestivum) cultivated. yield uptake determined. soil, matter content, pH, solution...

The objective of this research was to quantify the changes nitrogen (N) and phosphorus (P) balances in Poland Mississippi (MS), USA. Nutrient were calculated as difference between input output agricultural system according Organisation for Economic Cooperation Development (OECD) methodology. A positive nutrient balance means that a potential environmental problem may result from nutrient; negative there is yield loss. N P soil surface MS year 1998 through 2008. results showed both had...

The aim of this study was to evaluate the effects cover type (control, agro-textile or perforated plastic film) and harvest date (60 75 days after planting at full physiological maturity) on yield, quality cost-effectiveness early potato cultivation. conducted in years 2008–2011, Gorzyń Experimental-Education Laboratory for Soil Plant Cultivation, Branch, part University Natural Sciences Poznań. experiment set up a split-plot randomized block design with four replications. Covers increased...

Abstract Economic and political challenges impact agricultural practices, production efficiency, crop yields. We hypothesize that increased conversion efficiency of fertilizer to yield resulted from changes in management Central Eastern European countries. Efficient nutrient depends on applied, weather, which uptake, utilization yield. Trends consumption wheat yields 1986 2005 were studied for five There significant differences gap, defined as the difference between potential actual Partial...

Optimal nutrition of sugar beets at critical growth stages is one the crucial factors for achievement their highest yield potential. In present study, it was presumed that reduced systems beet cultivation had no effect on plants’ nutritional status stages, or technological quality. 2012-2013, two series one-factorial field experiments with different crop husbandry were carried out in order to verify this hypothesis. The crops differed postharvest technology, mulch types and seedbed tillage....
