Alterations in microbial communities can serve as an environmental indicator of possible soil contamination. We used two molecular fingerprinting methods (Automated Ribosomal Intergenic Spacer Analysis, ARISA and Terminal Restriction Fragment Length Polymorphism, T-RFLP) to study changes in the genetic diversity of bacterial communities in the rhizosphere of Arundo donax L. cultivated in the soil fertilised with additive based on sewage sludge from wastewater treatment plant and agricultural by-products represented by crushed corn hobs and wastes from grain mill industry. The metagenomic DNA extracted from rhizosphere samples were collected in August and November 2014. The amount of mgDNA was statistically higher in samples with additive than in control samples without it in both dates. The Venn diagrams showed that operational taxonomic units which were common to all samples were represented in 32.8% in ARISA and 43.4% in T-RFLP. However, based on Principal component analysis and subsequent PERMANOVA statistical tests did not confirm significant differences in the rhizosphere of control plants and plants grown in the soil supplemented with sewage sludge in dose 5 and 15 t/ha present in the additive.","PeriodicalId":7527,"journal":{"name":"Agriculture (Pol'nohospodárstvo)","volume":"65 1","pages":"37 - 41"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83402773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Treatments included: chicken manure, foliar application of ZnO + FeO (GNPs at a rate of 60 and 50 ppm, respectively), chicken manure plus ZnO + FeO (GNPs). This study revealed that growth and yield of radish plants significantly increased by ZnO + FeO nanoparticles application. The maximum vegetative growth, leaf pigments and root quality (diameter and weight) were recorded in plants treated with ZnO + FeO (GNPs) alone or in combination with chicken manure. Furthermore, the combined application of chicken manure with ZnO and FeO significantly improved the concentration of anthocyanins, phenols, tannins, flavonoids, crude protein and carbohydrates contents in radish root than single treatment. Similar trends were noted in photosynthesis rate, water use efficiency and values of Zn and Fe contents. In addition, health risk index for Zn and Fe were less than 1, which indicated to red radish plants supplied with ZnO and FeO GNPs were free of risks on human health. It was concluded that combination between chicken manure and ZnO + FeO GNPs can be considered as appropriate strategy for improving yield and nutritional status of red radish.","PeriodicalId":7527,"journal":{"name":"Agriculture (Pol'nohospodárstvo)","volume":"31 1","pages":"16 - 29"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85916832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 27 citrus cultivars belonged to Citrus sinensis, C. aurantifolia, C. aurantium, C. paradise, C. reticulata, C. limon, C. latifolia, C. maxima, C. limettoides, C. limetta, C. medica and C.

AFLP analysis using 4 primer pair combinations resolved 910 polymorphic alleles. All citrus cultivars and accessions had low genetic diversity (H = 0.0281 to 0.1300), with the percent polymorphic loci ranging from 8 to 35%. Populations of the six wild citrus accessions showed a very low level of genetic diversity (< 0.0700). Cluster analysis of the 33 cultivars and accessions showed that they share a high level of genetic similarity (81‒99%; mean = 92%). The six wild accessions clustered into two main clusters, with the analysis indicating that the six wild accessions may make up six distinct cultivars. The study provides information on the phylogeny of citrus cultivars and citrus diversity in Oman, a country through which citrus moved in the past from Asia to different African and European countries. In addition, it shows that some distinct citrus cultivars are present in this part of the world.","PeriodicalId":7527,"journal":{"name":"Agriculture (Pol'nohospodárstvo)","volume":"21 1","pages":"173 - 182"},"PeriodicalIF":0.0,"publicationDate":"2018-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83696534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The soil is Haplic Chernozem, loamy textured. Three variants were established: Variant 1 - control, no compost, Variant 2-30 t of compost per ha, Variant 3-60 t of compost per ha. The compost from pomace, poultry droppings, mown grass and straw was made in an EWA aerobic fermentor in an intensive and controlled process in an enclosed space and shallow ploughed (0-0.15 m) into the soil every year after harvest. The results of the experiment were statistically processed by multifactorial analysis of variance and then by Tukey’s test of simple contrasts. The highest values of structural coefficient and water stability of soil aggregate were found in the variant with the highest dosage of compost.

Heavy metals content was measured at three depths (0‒0.2 m, 0.2‒0.4 m and 0.4‒0.6 m). It was found that the average content of Pb was 1.4 times higher and content of Ni 2.3 times higher at experimental area than at reference area. The average content of Cd were on the same level (E - 0.040 mg/kg, R - 0.041 mg/kg). The variability of heavy metals content in the soil was significantly influenced by soil depth and sampling plot and concentrations significantly correlated with soil organic carbon content (r - in the range of 0.41 to 0.65, p < 0.05). Geo-accumulation index indicates that the soils in the all of studied plots were polluted with respect to Ni, while were unpolluted with respect to Cd and Pb. Cd and Pb occurrence in these soils may be associated to the geochemical weathering. The value of the ACR indicate that anthropogenic input of Ni was 1.331 times higher in flooded area than in reference no flooded area. Different soil types can be arranged in descending Igeo values for Ni as follows: Luvisols ˃ Regosols ˃ Gleysols ˃ Chernozems.

Therefore the BDW composting can decrease significantly the production of the landfill gas as well as the financial and space requirements for landfills. However, the composts production have to be solved comprehensively, including their rational usage. In Slovakia the use of composts is ineffective if the location of their production is farther than 50 km, because of the high tranportation costs. The objective of the experiments was to determine the ratio of vermicompost in the soil growing medium in order not to decrease the yield quantity and quality of radish - the most commonly grown vegetable in the gardens in Slovakia. Five shares of vermicompost were tested in the soil substrate (0%, 10%, 20%, 25% and 50%). The results show that 50% share of vermicompost in the soil substrate, i.e. the ratio of vermicompost to soil 1:1, was not the optimal solution of the vermicompost usage. However, even this quantity of vermicompost did not have a negative impact on the weight of the aboveground and underground phytomass in comparison with the treatment without vermicompost. 50% share of vermicompost in the growing medium had the negative impact on the qualitative parameters of radish. It decreased the content of vitamin C and increased the content of nitrates in radish roots and leaves. Along with the higher share of vermicompost in the growing medium, the content of vitamin C was decreased in radish roots and leaves, and the content of nitrates in radish roots was increased. The roots of the biggest diameter, and consequently the highest yield of radish roots and leaves was formed in the treatment where the soil substrate consisted of four portions of soil and one p ortion of vermicompost (20% proportion of vermicompost).","PeriodicalId":7527,"journal":{"name":"Agriculture (Pol'nohospodárstvo)","volume":"16 1","pages":"106 - 115"},"PeriodicalIF":0.0,"publicationDate":"2018-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80269825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
