“…Such nutrients from organic sources are more efficient in the different plant functions, such as protein and enzyme synthesis, than those from chemical sources [67,68] The observed increase in the growth and yield of maize in response to biogas slurry in the present study (Tables 3 and 4) might be due to its effect on cell development, enzyme regulation, and induction of the photosynthetic process. These results are consistent with the findings obtained by Lu et al [69] who demonstrated that the application of biogas slurry increased the rice yield by 24.0% and 4.9% as compared to no fertilization and conventional fertilization treatments, respectively. Moreover, the high P content of the slurry might also contribute to improving the biomass and yield of maize.…”

Expanding eco-friendly approaches to improve plant growth and crop productivity is of great important for sustainable agriculture. Therefore, a field experiment was carried out at the Faculty of Agriculture Farm, Mansoura University, Egypt during the 2018 and 2019 growing seasons to study the effects of different bio- and organic fertilizers and their combination on hybrid maize growth, yield, and grain quality. Seeds were treated with Azotobacter chrocoocum, arbuscular mycorrhizal fungi (AMF), Bacillus circulans, biogas slurry, humic acid (HA), and their combination aiming to increase the growth and yield of maize and to reduce the need for chemical fertilizers. The results showed that combined application of the biofertilizer mixture (Azotobacter chrocoocum, AMF, and Bacillus circulans) with organic fertilizers enhanced maize growth, yield, and nutrient uptake. Moreover, the bio-organic fertilization has improved the soluble sugars, starch, carbohydrates, protein, and amino acid contents in maize seeds. Additionally, the bio-organic fertilization caused an obvious increase in the microbial activity by enhancing acid phosphatase and dehydrogenase enzymes, bacterial count, and mycorrhizal colonization levels in maize rhizosphere as compared with the chemical fertilization. Additionally, the bio-organic fertilizers has improved α-amylase and gibberellins (GA) activities and their transcript levels, as well as decreased the abscisic acid (ABA) level in the seeds as compared to the chemical fertilizers. The obtained results of bio-organic fertilization on the growth parameters and yield of maize recommend their use as an alternative tool to reduce chemical fertilizers.

“…Thus, cow dung may not only act as a substitute for chemical fertilisers because it supplements organic matter, but also as a conditioner for soil (Garg and Kaushik 2005;Yadav et al 2013;Be´langer et al 2014). Slurry from biogas plant is also a nutrientrich source but it cannot be used at large scale because of its drawbacks such as eutrophication and leaching of the soil nutrients Wachendorf et al 2005;Islam et al 2010;Lu et al 2012;Guo et al 2014).…”

Cow dung, an excreta of bovine animal, is a cheap and easily available bioresource on our planet. Many traditional uses of cow dung such as burning as fuel, mosquito repellent and as cleansing agent are already known in India. Cow dung harbours a diverse group of microorganisms that may be beneficial to humans due to their ability to produce a range of metabolites. Along with the production of novel chemicals, many cow dung microorganisms have shown natural ability to increase soil fertility through phosphate solubilisation. Nowadays, there is an increasing research interest in developing the applications of cow dung microorganisms for biofuel production and management of environmental pollutants. This review focuses on recent findings being made on cow dung that could be harnessed for usage in different areas such as medicine, agriculture and industry.

“…As a liquid by-product in anaerobic digestion of organic waste, anaerobically digested slurry (ADS), is rich in N and offers a beneficial N source for crop cultivation (Arthurson, 2009). Field application of ADS may reduce greenhouse gas emissions (Amon et al, 2006;Meijide et al, 2007) and mitigate water pollution from direct discharge of ADS (Cho et al, 2000;Lu et al, 2012) to surface waters. In contrast to composting and direct burning, anaerobic digestion provides both fuel and fertilizer, rather than simply one or the other.…”

Field experiments were conducted during rainy seasons of 2017 and 2018 at National Wheat Research Program (NWRP), Bhairahawa to identify the suitable age and appropriate dose of digestate/biogas slurry regarding yield maximization of rice (cv. Ram dhan). The experiment compared the effect of different age [5 days (fresh), 90 days (3 months) and 180 days (6 months)] and dose (0, 5, 10 and 15 t ha-1) of digestate/biogas slurry on rice yield. The experiment was laid out in Randomized Complete Block design (RCBD) with three replications. Grain yield of rice was significantly higher (4.5 t ha-1) with the application of biogas slurry of 5 days than 90 days (4.3 t ha-1) age, in 2017 A. D. Similarly, yield was significantly higher (4.6 t ha-1) with the application of biogas slurry 5 days than of 90 days (4.5 t ha-1) age, in 2018. Yield due to the application of biogas slurry of 5 days was equal to the yield resulted from the use of biogas slurry of 180 days in 2017 and 2018. The pooled analysis showed that the yield with the application of biogas slurry of 5 days age was significantly higher (4.6 t ha-1) than the yield due to the application of biogas slurry of 90 (4. 4 t ha-1) and 180 days (4.5 t ha-1) age. The yield of rice has been found increasing significantly as the dose of biogas slurry was incremented from 0 t ha-1 to 15 t ha-1 in 2017, 2018 and in pooled analysis. The yield of rice was significantly higher (4.6 t ha-1) in 2018 than in 2017 (4.4 t ha-1), in pooled analysis. Thus, the use of biogas slurry of the age of 5 days with the dose of 15 t ha-1 produced the higher grain yield of rice.
