The study investigated the effects of animal manures (cow manure, CoM; chicken droppings, CkD; and pig manure, PiM) applied at 15 t ha-1 equivalent rate on the soil and growth performance of okra grown in a degraded ultisol. The treatments (CoM; CoM; PiM and Control unamended) were laid out in a completely randomized design and replicated three times. Animal manure application had significant effects on soil properties. Soilorganic matter increased by over 9% in the amended treatment relative to the control treatment. Except for N, increases in P (circa 14-70%)and K (circa 15-46%) nutrients were higher for CkD treatment than in other  treatments. Generally, the amended treatments maintained a significantly higher (p ≤0.05) plant leave number, stem girth, plant height, okra pod length and yields when compared with the Control treatment. The results indicated that application of animal manure enhanced okra growth performance. The findings suggest that animal manure application can potentially increase okra yield when grown in a degraded soil. It is recommended that farmers use ample (15 t ha-1) ) quantity of animal manures to increase their crop yields, which invariably will enhance their income. Keywords: Soil fertility, organic fertilizers okra growth, okra yield response, farmers okra yeild.

Abstract Background: The prevalence of antibiotic resistance genes (ARGs) in animal manure poses a threat to environmental safety. Organic fertilizers fermented by livestock and poultry manure are directly applied to farmland and have the potential to cause outbreaks of bacterial resistance in agricultural environments. This study investigated the composition of ARGs in different animal manures and their derived organic fertilizers. Results: The results showed that the abundance of several ARGs, such as sul 2, Tet B-01, Tet G-01 and Tet M-01, in organic fertilizer samples was 12%~96% lower than that in animal manure. However, the abundance of Tet K and erm C was higher in animal manure than in organic fertilizers. No correlation between ARGs and environmental factors such as pH, TN, and antibiotics was observed by redundancy analysis (RDA). Procrustes analysis revealed a significant correlation between bacterial community structures and ARG abundance (r=0.799, p<0.01). Nonmetric multidimensional scaling (NMDS) analysis suggested that microorganisms in organic fertilizer may be derived from animal manure. Additionally, the abundance of pathogenic bacteria (especially Actinomadura ) would increase rather than decrease in manure compared to organic fertilizer. Conclusion: The diversity and abundance of most ARGs significantly decreased from animal manure to organic fertilizer. Microorganisms in the prepared organic fertilizer may mainly be inherited from the animal manure. The results also showed that the pathogens in the prepared organic fertilizer would significantly reduce, but would still cause partial pathogen proliferation.

The World

Barley (Hordeum vulgare L.) is one of the ancient cereal crops of agriculture in the world and one of the first domesticated cereals and fourth largest cereal crop next to maize, wheat and rice in the world. It contributes seven percent of the total cereal production. The production of barley in Ethiopia reduced by many factors from these biotic factors including rodents, pathogens, diseases, weed, pests, insects and abiotic stress like drought, flooding, temperature stress, salinity, poor management practice, frost, poor soil fertility, agronomic practice etc. among those the most important factors that reduce yield of barley in Ethiopia are the use of inappropriate organic fertilizers. Thus, the main objective of this paper is to review the influence of organic fertilizers on productivity of barely. The review was done by collecting the various published and unpublished materials relevant information from different literature sources like libraries, research report, journals, books and Internet center. As various scholars mentioned organic fertilizers affect the growth, development and yield of barley. The uses of farm yard manure, animal manure, poultry manure and vermi compost considerably improved yield and yield component of barley such as number of tillers per plant, spike length, straw, biomass, grain weight and grain yield. It concludes using organic fertilizer has crucial role for increasing barley production and productivity.

Energy Autonomy

Agriculture has been considered as one of the priority countries sectors in our research; the share of agriculture in the gross domestic product of the world leading countries was investigated. The theoretical and practical aspects of non-waste agricultural production development using animal waste and crop residues fermented in biogas plants are revealed. The authors substantiate the relevance and potential of the introduction of waste-free technology which has considerable advantages of energy autonomy both for the enterprise and the country. The state of humus content in soils of Ukraine is also considered. International experience has been evaluated, which consists in the ability of agricultural waste both to produce alternative sources of energy and to use the products of their processing as organic fertilizers that significantly increase crop yields. The first steps of the Ukrainian agricultural enterprises to introduction of non-waste production on the example of the company LLC Organic-D have been presented; it heats and electrifies the complex, dries crops, and also uses organic fertilizer (digestate) due to waste processing in the biogas station. As a result of the research, it was found that the application of organic fertilizer can have a positive effect on soil recovery, because the soil acidity has changed from a level of weak acid (5.4 pH) to a level close to neutral (6 pH) for one year of its application. To conclude, the obtained results prove the relevance of the research problem.

Study Results

Assessment for increasing productivity of suboptimal land with using three kinds of organic fertilizer and six rice varieties had been conducted in the Debowae village, Waeapo district, Buru regency at 2011.  Purpose of the assessment were to determine the effect of three types organic fertilizer and the use of six Inpara varieties to growth and productivity of rice in sub-optimal land. Study used a split plot design with three replications (farmers as replicates), where the main plot was three types of organic fertilizers (livestock manure, granular organic, and petroganic), while the subplot was 6 varieties Inpara (Inpara 1, Inpara 2, Inpara 3, Inpara 4, Inpara 5, and Indragiri). The soil types at the study site based on soil classification were Endoaquepts with soil fertility status was low. The study results  showed  that  the use of organic  manure combined with inorganic fertilizers,  both  from  livestock manure, while granular organic and petrogranic, gave an average crop growth and yield better than the results obtained by farmers outside of the study. Average petroganic fertilizer had a better growth and higher crop yields compared to other organic fertilizers. The six varieties of rice swamps that were examined (Inpara 1, Inpara 2, Inpara 3, Inpara 4, Inpara 5, and Indragiri) had the average growth and better yields than rice varieties used by farmers outside of the study (2.75 t ha-1). Varieties Inpara 4, Indragiri, Inpara 1 and  Inpara 2 had average yield above 7 t ha-1, while Inpara 3 and  Inpara 5 average above 4 t ha-1. Combination of granular organic fertilizer with Inpara 4 variety and petroganic with Indragiri variety had the best results (8.37 and 8.02 t ha-1), while the lowest yield (4.48 t ha-1) was reached at combination of  livestock manure with Inpara 5 variety.Keywords: adaptive varieties, land and plant management, organic fertilizers, suboptimal land [How to Cite: Marthen PS and MLJ Titahena. 2014.

No correlation between ARGs and environmental factors such as pH, TN, antibiotics was observed by Redundancy analysis (RDA). Procrustes analysis revealed the significant correlation between bacterial community structures and the ARGs abundance (r=0.799, p<0.01). Non-metric multidimensional scaling (NMDS) analysis suggested that microorganisms in organic fertilizer may be derived from animal manure. Additional, pathogenic bacteria (especially Actinomadura ) would proliferate rather than decrease from manure to organic fertilizer. Conclusion: Overall, this research suggests that the composting treatment of manure could effectively reduce these ARGs and pathogens,even cause partial ARGs and pathogens proliferation. It also shows that the microorganism might significantly influence ARGs profiles in composting.

A field experiment was carried out in the field of  College of Agriculture / University of Wasit, located on longitude 45o 50o33.5o East and latitude 32o 29o 49.8o  North, in the spring agricultural season 2019. The experiment was designed according to Randomized Complete Block Design (RCBD) with three replication and four treatments that include each of the SWRT treatment (use of plastic films under plant root area in an engineering style) treatment of vegetal fertilizer (using Petmos), organic fertilizer (sheep manure), and control treatment. The bulk density values of soil profile for the season increased compared to their values before planting. It is noticed that the values of bulk density of soil increased with depth, ranging between 1.22 - 1.27 Mg m-3 for SWRT treatment and between 1.28 - 1.31 Mg m-3 for plant fertilizer treatment and between 1.22 - 1.32 Mg m-3 for animal manure treatment and between 1.29-1.34 Mg m-3 for control treatment. The values of saturated hydraulic conductivity of soil decreased with depth after the end of the season ranged between 0.41-0.47 cm / hour for SWRT treatment and between 0.21 -0.24 cm / hour for petmos treatment and between 0.14-0.2 cm / hour for animal manure treatment and between 0.17-0.2 cm / hour for control treatment. The rate of infiltration rate and accumulative infiltration decreased for all treatments after the end of potato growth season compared to their value before planting, and the SWRT treatment gave the highest values compared to the rest treatments.

Abstract Background Bio-organic fertilizers has been shown to improve crop yields, partially because of the effects on the structure and function in resident soil microbiome. Purpose and methods Whereas, it is unknown if such improvements have been facilitated by the particular action of microbial inoculants, or the compost substrate. To understand the ecological mechanisms to increase crop productivity by bio-organic fertilizers, we conducted a pot experiment tracking soil physicochemical factors and extracellular enzyme activity over two growth stages and variations of soil microbial communities caused by fertilization practices as below: Bacillus subtilis CY1 inoculation, swine compost, and bio-organic fertilizer. Results Results showed that different fertilization measures, especially bio-organic fertilizers, increased soil nutrients, enzyme activity, and the diversity of microbial communities. For quantifying the “effect size” of microbiota manipulation, we discoverd that, respectively, 19.94% and 48.99% of variation in the bacterial and fungal communities could be interpreted using tested fertilization practices. Fertilization-sensitive microbes showed taxonomy diversity and gave responses as guilds of taxa to specific treatments. The microbes exhibited medium to high degree of co-occurrence in the network and could be recruited, directly or indirectly, by B. subtilis CY1, suggesting that bio-organic fertilizer may allow manipulation of influential community members.Conclusion Together we demonstrated that the increase in tomato productivity by bio-organic fertilizer was caused by the synergistic effect of organic fertilizer and beneficial microorganisms, thus providing novel insights into the soil microbiome manipulation strategies of biologically-enhanced organic fertilizers.
