“…The experimental results revealed that application of organic fertilizer (vermicompost) improves seed germination rate and enhanced growth of tested plants. These may be due to that vermicompost provides mineral nutrients in available forms to plants (Grantina-Ievina et al, 2015). These plant growth-promoting activity of vermicomposts usually for the high content of humic compounds (Muscolo et al, 1999).…”

Growth attributes of Vigna mungo and Vigna radiata crop influenced by level and type of fertilizers. The present study was carried out to evaluate and compare the effects of organic (vermicompost) and inorganic (urea) fertilizers on the germination percentage and seedling growth of V. radiata (Green gram) and V. mungo (Black gram). Fresh weight and dry weight of tested plant samples at 10th days of growth stage were also determined. Vermicompost was used as organic fertilizer and urea as inorganic fertilizer. Experimental results showed that vermicompost and urea both has positive effect on seedling growth parameters of V. mungo and V. radiata [average root length (6.1cm and 6.7cm)] , shoot length (6.5cm and 8.3cm), leaf area (312.2 sq.cm and 334.1 sq.cm] as compared to control set [average root length (4.4cm and 4.3cm)] , shoot length (6cm and 5.9cm), leaf area (282.7 sq.cm and 305.5 sq.cm). But urea exerts negative effect on seed germination percentage in V. mungo and V. radiata (58% and 50%) as compared to control (77%). Vermicompost exhibited better result in above parameters in comparison to urea. V. mungo showed increased value in comparison considering V. radiata in case of organic, inorganic fertilizer treated as well as control sets. As composition of locally available fertilizers is unknown, the application of these fertilizers for improving germination percentage and growth parameters of tested crop need to be evaluated. Present work may provide the suggestive approach for usage of these tested fertilizers in field level trial.

“…Mineral nutrients in plant-available forms are one of the beneficial characteristics of vermicompost (Grantina-Ievina et al, 2015). The actual concentrations of various inorganic nutrients in particular vermicompost preparations depend on the initial mineral composition of the feedstock used as well as on intensity of mineralisation activity of respective microorganisms during precomposting and vermicomposting stages (Domínguez, 2004;Pattnaik and Reddy, 2010).…”

“…Recent studies have shown that soil microbial communities differ considerably with respect to cultivated plants, soil parameters and treatments [6,7,8,9]. Soil amendments like green manure, dung and chitin affect soil microbiome compositions and soil suppressiveness [10,11,12,13]. It has been hypothesized that disease suppressiveness is mediated by microbial consortia composed of multiple species rather than single microorganisms [14].…”

To follow the hypothesis that agricultural management practices affect structure and function of the soil microbiome regarding soil health and plant-beneficial traits, high-throughput (HT) metagenome analyses were performed on Chernozem soil samples from a long-term field experiment designated LTE-1 carried out at Bernburg-Strenzfeld (Saxony-Anhalt, Germany). Metagenomic DNA was extracted from soil samples representing the following treatments: (i) plough tillage with standard nitrogen fertilization and use of fungicides and growth regulators, (ii) plough tillage with reduced nitrogen fertilization (50%), (iii) cultivator tillage with standard nitrogen fertilization and use of fungicides and growth regulators, and (iv) cultivator tillage with reduced nitrogen fertilization (50%). Bulk soil (BS), as well as root-affected soil (RS), were considered for all treatments in replicates. HT-sequencing of metagenomic DNA yielded approx. 100 Giga bases (Gb) of sequence information. Taxonomic profiling of soil communities revealed the presence of 70 phyla, whereby Proteobacteria, Actinobacteria, Bacteroidetes, Planctomycetes, Acidobacteria, Thaumarchaeota, Firmicutes, Verrucomicrobia and Chloroflexi feature abundances of more than 1%. Functional microbiome profiling uncovered, i.a., numerous potential plant-beneficial, plant-growth-promoting and biocontrol traits predicted to be involved in nutrient provision, phytohormone synthesis, antagonism against pathogens and signal molecule synthesis relevant in microbe–plant interaction. Neither taxonomic nor functional microbiome profiling based on single-read analyses revealed pronounced differences regarding the farming practices applied. Soil metagenome sequences were assembled and taxonomically binned. The ten most reliable and abundant Metagenomically Assembled Genomes (MAGs) were taxonomically classified and metabolically reconstructed. Importance of the phylum Thaumarchaeota for the analyzed microbiome is corroborated by the fact that the four corresponding MAGs were predicted to oxidize ammonia (nitrification), thus contributing to the cycling of nitrogen, and in addition are most probably able to fix carbon dioxide. Moreover, Thaumarchaeota and several bacterial MAGs also possess genes with predicted functions in plant–growth–promotion. Abundances of certain MAGs (species resolution level) responded to the tillage practice, whereas the factors compartment (BS vs. RS) and nitrogen fertilization only marginally shaped MAG abundance profiles. Hence, soil management regimes promoting plant-beneficial microbiome members are very likely advantageous for the respective agrosystem, its health and carbon sequestration and accordingly may enhance plant productivity. Since Chernozem soils are highly fertile, corresponding microbiome data represent a valuable reference resource for agronomy in general.
