Cancer is the second leading cause of death in the world. Chemotherapy and radiotherapy (RT) are the common cancer treatments. In addition to these limitations, the development of adverse effects from chemotherapy and RT reduces the quality of life for cancer patients. Cellular radiosensitivity, or the ability to resist and overcome cell damage caused by ionizing radiation (IR), is directly related to cancer cells’ response to RT. Therefore, radiobiological research is emphasizing chemical compounds ’radiosensitization of cancer cells so that they are more reactive in the IR spectrum. Recent years researchers have seen an increase in interest in natural products that have antitumor effects with minimal side effects. Natural products, on the other hand, are easy to recover and therefore less expensive. There have been several scientific studies done based on these compounds that have tested their ability in vitro and in vivo to induce tumor radiosensitization. The role of natural products in RT, as well as their usefulness and potential applications, is the goal of this current review.

Soil plays a key role in sustainable land management and food production. The objective of the field experiment was to evaluate the subsequent effect of 10-year winter wheat and sugar beet cultivation under conventional and organic systems on selected physicochemical and biochemical properties and enzymatic pH index of lessive soil developed from loess under climatic conditions of Southeastern Poland. The experiment was set up by using the split-plot design, with three replications, on plots of 30 m². In order to evaluate the soil value of sites cultivated in 2010–2019 in two systems—conventional agriculture and organic agriculture—spring wheat was sown as a test crop in 2020. Fertilization and pesticide applications (herbicides, fungicides and insecticides) were foregone in the cultivation of this crop due to the desire to capture the subsequent impact of 2010–2019. This resulted in soil properties shaped solely by the previous 10 years of cultivation. The obtained results indicate that the organic farming system contributed to the improvement of soil pH_KCl compared to the conventional system, with statistically significant differences recorded only for winter wheat cultivation. Compared to the conventional system, in the organic farming system, improvements were recorded in the chemical indicators of loess soil quality (TOC, TN and TOC/TN) and P content, as well as acid phosphatase and alkaline phosphatase activities. However, statistically significant differences were found only for winter wheat cultivation. Research on the impact of an organic system of growing different species in rotation should be continued, and the results should be implemented.

Agricultural research has traditionally focused on staple crops, while relatively little attention has been given to minor crops. Therefore, this study aimed to determine the nutrient contents and some anti-nutritional factors in the seeds of common vetch (Vicia sativa L.) and the variation of phenotypic and morphological traits in field studies of 44 European accessions, originating from Russia, Ukraine, Poland (east and east-central Europe), the Czech Republic, the Slovak Republic, Hungary (south-central Europe), and Germany (west-central Europe) and grown in the same soil-climate conditions. A three-year field study was conducted from 2010 to 2012. Accessions originating from west-central Europe flowered three days earlier than those from south-central Europe. They also had the lowest seed number per pod (5.9) but the highest thousand seed weight (58 g) (p < 0.05). Vetch lines coming from south-central Europe contained the highest level of crude protein in comparison with vetch seeds originating from west-central Europe (353 vs. 324 g kg⁻¹, respectively) (p < 0.05), but the latter had the highest essential amino acid index value (75 vs. 71 in west-central Europe and south-central Europe, respectively) (p < 0.05). The highest protein level was noted in the seeds of Slovak origin (average 358 g kg⁻¹), whereas the lowest protein level (324 g kg⁻¹) was determined in the Russian and German lines. Vetch grain fat was rich in linoleic (53%) and linolenic (14%) acids. The best n-6/n-3 fatty acid ratio (4) and the highest α-linolenic acid level were exhibited by the Slovak and Polish accessions (p < 0.05). The seeds of vetch accessions from east, east-central, and south-central Europe contained higher levels of (p < 0.05) iron than those originating from west-central Europe. The concentration of tannins, trypsin inhibitors, and hydrogen cyanide reached on average 8, 3, and 81 mg kg⁻¹, respectively. The highest hydrogen cyanide (HCN) levels was determined in the accessions of German and Russian origin (126 and 119 mg kg⁻¹, respectively), and the lowest values were noted in the Slovak and Polish lines (50 and 67 mg HCN kg⁻¹, respectively). Furthermore, the Polish accessions contained the lowest levels of tannins and trypsin inhibitors. Common vetch seeds may be valuable protein feed/food stuff, but their nutritional usefulness is limited by the presence of anti-nutritional factors, especially HCN, which is difficult to remove. Further selection in this direction may be postulated.

The aim of this three-year field experiment was to determine how simplified (reduced) pre-planting tillage and different weed control methods impact the yield and selected quality parameters of spelt grain (Triticum aestivum ssp. spelta L.). Conventional tillage and three variants of reduced tillage (RT) were tested. The second experimental variable (weed control) had three variants: mechanical weed control (M), combined mechanical + chemical treatment at full herbicide rate (MC 100%), and combined mechanical + chemical treatment at 25%-reduced herbicide rate (MC 75%). The mechanical method consisted of harrowing the wheat crop in the fall and spring. The results showed that the wheat yields obtained under reduced pre-planting tillage were comparable to those under conventional tillage. However, the grain quality parameters proved to be worse under the reduced tillage regimes. Herbicide applications, both at full and reduced rates, significantly improved grain quality parameters and yields compared with mechanical-only weed control. In particular, the herbicide-treated crops boasted higher values of thousand-kernel weight and grain weight per ear.

Organic farming is system with a growing interest worldwide. The objective of this paper was an assessment of the after-effects of perennial cultivation of spring barley, oats, and red clover in both conventional and organic systems on the chemical properties, enzymatic activity, and potential...
