“…Similarly, in another report, Oosterhuis et al (2014) revealed that synthesis and accumulation of carbohydrates in shoots increased biological processes like root development, photosynthesis, and energy transfer reactions due to the application of potassium. The positive yield response to NPK application was also reported in potatoes by Gondwe et al (2020). The inoculation of biofertilizers such as Azotobacter and Azospirillum with neem cake along with different levels of nitrogen fertilizer significantly boosts the NPK content in plants as compared to uninoculated control and other treatments (Gao et al, 2020;Cassan et al, 2020).…”

Root-knot nematodes are believed to be amongst the biological constraints causing severe damage and a great reduction in the productivity of okra. The purpose of this study was to apply organic matter and non-symbiotic nitrogen-fixing bacteria to minimize the addition of chemical fertilizers that constantly pollute the environment. Experimental studies were conducted in the field for two summers to determine the effect of inoculations of non-symbiotic nitrogen-fixing bacteria, such as Azotobacter chroococcum and Azospirillum brasilense singly and in combinations, with different recommended doses of inorganic nitrogen as well as organic matter such as neem seed cake on the growth, yield, and organic parameters of the okra crop towards the management of plant-parasitic nematodes. The results show a significant reduction in nematode multiplication through soil application of nitrogen-fixing bacteria and neem seed cake along with different recommended doses of nitrogen inoculated plants. Azotobacter was found to be less effective than Azospirillum in agronomic parameters and nematode control. The most pronounced increases were observed in the yield and growth parameters such as plant height, fresh as well as dry weights, fruit weights/plant, number of total fruits/plant and primary branches, chlorophyll content, and ascorbic acid content when A. chroococcum and A. brasilense were added concomitantly in various combinations. Agronomic parameters such as NPK content in the plant as well as in residual soil increased considerably in almost all the combinations irrespective of these biofertilizers and neem seed cake. In conclusion, the combined application of a 100% recommended dose of nitrogen fertilizer along with Azospirillum and neem seed cake is recommended for better growth and yield of okra with better control of nematodal population.

“…This correlation is dependent on anion concentration and nearly independent of the tested cation (mono, bi, or trivalent metal cation), although the redox ferrous cation did not overlay fully with the other cations and the weakly ionic acetate anion showed a reduced range. While this detection window lies below typical concentrations of ions in biological fluids, it matches that of trace metal contaminants in drinking water and the presence of soil nutrients such as phosphate, nitrate, phosphate and potassium [25,26]. The work demonstrated that the measurement does not require direct contact between the sample and the electrodes for conductivity measurements.…”

“…Generally, the increased nutrient level in soils has been linked with improved plant performance. High amounts of available nitrogen, phosphorus and potassium in soil improve crop quality and yield [34]. It has been previously observed that the amount of organic matter in soil is directly proportional to the yield production [35].…”

Application of Bioorganic Fertilizer on Panax notoginseng Improves Plant Growth by Altering the Rhizosphere Microbiome Structure and Metabolism

Bioorganic fertilizers can alleviate (a) biotic stresses and sustainably increase crop yields. The effect of bioorganic fertilizers on the rhizosphere bacterial community of Panax notoginseng and soil metabolism remains unknown. Here, we tracked the changes in the soil physicochemical properties, bacterial microbiota responses, and soil metabolic functions after the addition of a bioorganic fertilizer in a P. notoginseng field. The application of a bioorganic fertilizer reduced the soil acidification, improved the organic matter, and increased the contents of the total/available soil nutrients. Soil amendment with a bioorganic fertilizer significantly affected the structure of the rhizosphere bacterial community, leading to the enrichment of specific bacterial consortia such as Rhodanobacter, Arthrobacter, Sphingomonas, Devosia, Pseudolabrys, Luteimonas, Lysobacter, Nitrosospira, and Nakamurella. Previously, many of these genera have been associated with nutrient cycling, plant productivity, and disease suppression. Metabolome analysis further highlighted that the bioorganic fertilizer treatment significantly reduced phenolic acids and flavonoids and enhanced organic acids, saccharides and alcohols, and amino acids. This result indicates a high survival of bacterial microbiota in the rhizosphere and an availability of nutrients for P. notoginseng growth. This work showed that the application of bioorganic fertilizers significantly improves soil health status, alters soil metabolic functions, and stimulates a specific subset of rhizosphere microbiota for nutrient cycling and disease protection in P. notoginseng.
