Impact of organic fertilizers on morphological characteristics of giloy (tinospora cordifolia) in Jharkhand

Tinospora cordifolia (Willd.) Hook. f. & Thoms., commonly known as Giloy, belonging to the family Menispermaceae and is an important medicinal plant. The plants of Tinospora cordifolia were planted in Randomized Block Design (RBD) with 12 treatments and 3 replications in a plot size of 2 m x 2 m at a spacing level of 100 cm x 100 cm. The experiment was conducted at the Botanical Garden, PG Department of Botany, Vinoba Bhave University, Hazaribag (Jharkhand). The plant is used in Ayurvedic “Rasayanas” to improve the immune system and the body’s resistance against infections. Four seedlings were transplanted into each plot for each treatment. The useful part of this plant is the stem and the effectiveness of its medicinal value depends upon its thickness. The objective of this research work to find out the impact of organic fertilizer on the morphological characteristics (including stem thickness) of the Giloy plant. Maximum stem diameter (20.67 mm) was recorded from the application of Farm Yard Manure (FYM) 10 t ha-1 . Hence, it can be concluded that Farm Yard Manure (FYM) was best for the commercial cultivation of the Giloy plant.

Body size: A hidden trait of the organisms that influences the distribution of antibiotic resistance genes in soil

Body size is a key life-history trait of organisms, which has important ecological functions. However, the relationship between soil antibiotic resistance gene (ARG) distribution and organisms' body size has not been systematically reported so far. Herein, the impact of organic fertilizer on the soil ARGs and organisms (bacteria, fungi, and nematode) at the aggregate level was analyzed. The results showed that the smaller the soil aggregate size, the greater the abundance of ARGs, and the larger the body size of bacteria and nematodes. Further analysis revealed significant positive correlations of ARG abundance with the body sizes of bacteria, fungi, and nematodes, respectively. Additionally, the structural equation model demonstrated that changes in soil fertility mainly regulate the ARG abundance by affecting bacterial body size. The random forest model revealed that total phosphorus was the primary soil fertility factor influencing the body size of organisms. Therefore, these findings proposed that excessive application of phosphate fertilizers could increase the risk of soil ARG transmission by increasing the body size of soil organisms. This study highlights the significance of organisms' body size in determining the distribution of soil ARGs and proposes a new disadvantage of excessive fertilization from the perspective of ARGs.

Impact of organic fertilization on establishing an agroforestry system in a semi-arid Brazilian region

Improving soil fertility with organic sources is crucial, particularly in degraded regions. Organic fertilizers, when integrated into systems, provide cost-effective solutions. This study aimed to assess the impact of various organic fertilizers on the establishment of an agroforestry system in Planosol in a semi-arid region of Ceará State, Brazil. We used a randomized block design arranged in split plots. Four organic fertilizer sources (sheep manure, cattle manure, carnauba palm straw, and control) were assigned to the main plots. Evaluation years for annual crops (2015, 2017, and 2019) and for trees (2015 through 2017, and 2019) were allocated to subplots, with three replicates. All organic fertilization sources received an annual rate of 10 t ha-1, broadcasted uniformly. Experimental plots, spanning 18 x 7 m, were intercropped with maize and cowpea between rows of trees (Mimosa caesalpiniifolia and Spondias mombin). We examined soil fertility, tree growth, and crop grain yield. Soil chemistry, notably P and K, showed marked improvement with sheep manure. Organic fertilization did not enhance tree growth in the newly established agroforestry system. However, organic fertilization elevated maize and cowpea grain yields by over 60% and 90%, respectively, compared to the control. In conclusion, the use of sheep manure, cattle manure, and carnauba palm straw can significantly boost maize and cowpea grain yields in an agroforestry system found in the semi-arid region of Ceará, Brazil.

The application of growth stimulators enhanced seedlings growth, where Taravert Evo gave the best results in the leaf content of N, P, and K. As for the interaction between the treatments, the M2S6 interaction treatment achieved a significant superiority in the leaf content of N, P, K, carbohydrates and C:N ratio.

Impact of organic fertilization by the digestate from by-product on growth, yield and fruit quality of tomato (Solanum lycopersicon) and soil properties under greenhouse and field conditions

BackgroundThe application of organic fertilizer is a sustainable approach to maintain soil fertility in agricultural crop production. In contrast to other organic fertilizers, the digestate from by-products of anaerobic digestion has not been well characterized in terms of its agronomic properties. In this study, different fertilization treatments were investigated to evaluate their impacts on growth, yield and fruit quality of tomatoes and on soil properties under greenhouse and field conditions. The experiments comprised a control (unfertilized) and three treatments with the same nitrogen dose: chemical fertilizer, digestate from by-product (organic fertilizer) and digestate combined with chemical fertilizer.ResultsThe results showed that the application of digestate significantly increased the growth and fruit quality of tomato including height, stem diameter, leaf chlorophyll content index, and photosynthetic rate of tomato plant and sugar–acid ratio, protein content, and ascorbic acid content of the fruit. The nitrate contents in tomato fruit were lower in the digestate treatment and digestate combined with chemical fertilizer treatment than in the chemical fertilizer. The digestate combined with chemical fertilization resulted in the greatest increase in tomato yield, up to 26.29% and 10.78% higher than that in the chemical fertilizer treatment under field and greenhouse conditions, respectively. Moreover, fertilization with digestate treatment and digestate combined with chemical fertilizer treatment increased soil fertility, including soil nitrogen and carbon contents, and enhanced soil enzyme activities under both field and greenhouse conditions. In addition, the growth, yield, and fruit quality of tomato were significantly correlated with soil chemical characteristics and soil enzyme activities.ConclusionsThe effects of digestate treatments to maintain a stable tomato yield and improve fruit quality may be due to the enhanced soil enzymatic activities and chemical properties. These results suggest that the use of digestate as a full or partial replacement for chemical fertilizer could improve the growth and fruit quality of tomato, maintain the yield, and reduce the use of inorganic fertilizers in tomato production.Graphical

BIOTECHNOLOGICAL PROCESSING OF ORGANIC POULTRY WASTE AND ITS USE IN AGRICULTURE

Up-to-date biotechnologies are involved in the biological transformation of organic poultry waste into an environmentally friendly fertilizer that can preserve soil fertility and significantly improve yields. Currently, no more than 35% of livestock manure is used as a fertilizer in Uzbekistan. The use of poultry manure at poultry farms in Uzbekistan has been poorly addressed today. Poultry manure is discarded outside the poultry farms, where it is either filled with pits not suitable for storage or unloaded in a specially designated area. Afterwards, it is not used and causes tremendous damage to the environment. At the same time, bird droppings contain high macro and microelements, which form the basis for their value as organic fertilizers. The article analyzes and summarizes the practical use of biotechnological processing of bird droppings into a fertilizer and its further application on strawberry seeds as one of the reasonable solutions to the economic and environmental safety of poultry production under industrial conditions. The relevance of the topic. The solution to the problem of manure recycling is to improve the environmental situation, soil fertility and crop yields. The research is aimed at processing organic poultry waste and the impact of organic fertilizer, which is based on chicken manure, on soil fertility and crop yields. The laboratory and field studies on poultry waste management have been carried out on the territory of OOO Silver Eagle Plus (LLC) poultry farm in Tashkent region using the method of anaerobic fermentation and assessment of organic fertilizer quality as the most rational one for agriculture. The studied objects have been organic waste from OOO Silver Eagle Plus (LLC) poultry farm in Tashkent region, meadow soil and Joydori strawberry seeds. The research results have shown that the method of methane digestion is effective against pathogens in organic poultry waste; the process increases the number of useful bacteria and the generation of metabolites such as organic acid. Biotechnological poultry waste disposal reduces the processing time of the source material by 1.5 times. The study has revealed that the application of organic fertilizer based on chicken droppings has had a positive impact on soil structure, which has enhanced its aeration and ensured proper vegetative root system development.

Long-term manure amendment reduces nitrous oxide emissions through decreasing the abundance ratio of amoA and nosZ genes in an Ultisol

Organic fertilizers are frequently applied to soils to improve soil multifunctionality and maintain crop productivity in agricultural practices. However, how organic fertilizations influence soil nitrous oxide (N2O) emissions remains ambiguous, especially considering their linkage with the abundance of nitrogen (N)-cycling microorganisms. Here, we conducted an incubation experiment to examine the effect of partial replacement of mineral fertilizers with organic fertilizers on the abundance of N-cycling functional genes and N2O emissions at 60 % and 100 % water-filled pore space (WFPS) in an acidic Ultisol. Soil samples were collected from 32-year fertilization trials, including four treatments of control (no fertilizer), mineral NPK fertilizer (NPK), NPK + Peanut Straw (NPKS), and NPK + Pig Manure (NPKM). The N2O emissions from soils incubated at 100 % WFPS were significantly higher than those at 60 % WFPS in all treatments. Compared with NPK, NPKS and NPKM reduced N2O emissions, with a more pronounced effect in NPKM. The N2O flux was positively associated with the abundance of AOA and AOB amoA genes, and the abundance ratio of amoA/nosZ (i.e., the ratio of AOA amoA plus AOB amoA and nosZ І plus nosZ ІІ) when the peak N2O flux appeared. Random forest analysis showed that the abundance ratio of amoA/nosZ was the best predictor for N2O emissions. Compared with NPK, NPKM increased soil pH but reduced the abundance ratio of amoA/nosZ, which might be the key factor in reducing N2O emissions. Together, our findings suggested that long-term manure application reduced N2O emissions by decreasing the abundance ratio of amoA/nosZ and provided novel insights into the impact of organic fertilizers on N2O emissions in acidic agricultural soils.

The Influence of Planting Density on Maize-Soybean Intercropping Inoculated with Organic Fertilizer

Mycorrhizae and organic fertilizers play a critical role in nutrient availability and absorption, soil texture development, and hormone production to promote plant growth. The aim of this research was to determine the influence of planting density on intercropping maize and mycorrhizal soybeans, and the impact of organic fertilizers on maize and soybean yields in dry lands in North Lombok. The experiment was conducted using a randomized block design with five intercropping treatments: P1 = 2 maize lines: 2 soybean lines, P2 = 3 maize lines: 2 soybean lines, P3 = 3 maize lines: 3 soybean lines, P4 = 4 maize lines: 2 soybean lines, and P5 = 4 maize lines: 3 soybean lines. The data were then analyzed using two-way ANOVA and Tukey’s significant difference test with a significance level of 5%. It was found that the P3 density showed the highest yield compared with the other intercropping treatments; the number of spores and mycorrhizal infection rate were also increased. The P3 treatment, with the addition of 15 tons of cow manure per hectare and inoculation with AMF, enhanced the yield and promoted the development of mycorrhiza.

The impact of organic fertilizers on the carbon source/sink balance of tobacco soil ecosystem remains controversial. A two-year field experiment was conducted to investigate the effects of different fertilization treatments(no fertilizer,chemical fertilizer, chemical fertilizer and organic fertilizer) on greenhouse gas (GHG) emissionsincludingsoil carbon dioxide (CO2), nitrous oxide (N2O), ammonia volatilization and comprehensive greenhouse effects. The results showed that tobacco soil ecosystem can be carbon source orsink, depending mainly on the carbon sequestration of the plant. Comparing with chemical fertilizer, the combined application of chemical fertilizer and organic fertilizer increased the CO2emission flux and C emission from soil, and significantly increased the carbon sequestration of tobacco plants. The carbon sequestration function of organic fertilizer was closely related to the carbon accumulation of tobacco plants. Comparedwith the chemical fertilizer, soil ammonia volatilization and N2O emission flux were increased by adding organic fertilizer. Both the soil N emission and the biological nitrogen fixation were increased by organic fertilizer. The greenhouse gas emission intensity(GHGI)of organic fertilizer treatment decreased by 14.60%, a remarkable emission reduction, whilethe tobacco yield of organic fertilizer treatment increased 19.12%. Therefore, increasing organic fertilizer in tobacco planting fields is an important way to promote tobacco yield, carbon sequestration and emission reduction.© 2021 Friends Science Publishers

Mycorrhizae are symbiotic associations between fungi and host plants, which confer several advantages, including good mineral nutrition. Arbuscular mycorrhizal fungi (AMF) then present an effective alternative in order to develop a sustainable agriculture that is less dependent on mineral fertilizers. The objective of this study was to assess the impact of organic fertilizers based on native arbuscular mycorrhizal fungi on increasing maize productivity and improving soil health in North Benin. For this study, three mycorrhizal fungi strains (Glomeraceae sp., Acaulosporaceae sp. and Diversisporaceae sp.) were used with or without mineral fertilizers. The corn variety 2000 SYN EE-W was used. The experimental design is a randomized complete block of nine treatments with three replicates. After 65 days, the endomycorrhizal infection was evaluated. The results showed that mycorhizal fungi had a positive impact on the different plant growth parameters (height, leaf area, and yield). At the height level, Acaulospora + ½ dose of N15P15K15 recommended + urea produced good results compared to the control, an increase of 24.9%. The same observations were made for leaf area and yield, an increase of 70.4 and 39.04%, respectively. However, the results show that the rate of endomycorrhizal infection is high with Diversisporaceae sp. + 50% of recommended N15P15K15 + urea followed by Glomeraceae sp. + 50% of recommended N15P15K15 + urea and Acaulosporeacea sp.+ 50% of recommended N15P15K15 + urea. In terms of spore number, the treatment Glomeraceae sp. gave the best result. Key words: Mycorrhizal fungi, organic fertilizer, corn, Benin.

The Structure of Bacterial and Fungal Communities in the Rhizosphere and Root-Free Loci of Gray Forest Soil

The taxonomic composition, abundance, and diversity of bacterial and fungal communities in the rhizosphere loci and bulk mass of the gray forest soil (Eutric Retisol (Loamic, Aric, Cutanic, Humic)) under potatoes, maize, and white mustard grown with the application of mineral and organic fertilizers were compared. Among bacteria, Bacillus megaterium and Paenibacillus polymyxa species predominated in all the experimental variants. The micromycete community was represented by 39 species belonging to 19 genera. Under the impact of organic fertilizers, the abundance of Trichoderma harzianum—an antagonist of many phytopathogens—increased. A decrease in the abundance of representatives of Fusarium genus was observed both in the rhizosphere and in the bulk soil. Fertilization was the most significant factor determining the structure and diversity of micromycete communities both in the soil and rhizosphere. The application of mineral fertilizers reduced the diversity of micromycetes in soil, whereas the use of organic fertilizers increased it. In general, organic fertilizers proved to be more favorable for the rhizosphere and bulk soil mycobiomes and for the total soil suppressiveness than the mineral fertilizers.
