Effect of Integrated Nutrient Management with OUAT Consortia on Nutrient Uptake of Kewda in North Eastern Ghat Zone of Odisha, India | Chapter 3 | Agricultural Sciences: Techniques and Innovations Vol. 5

 

Kewda (Pandanus odoratissimus) is one of the most remunerative crops of Ganjam district of Odisha, as 95% of kewra flowers exported from India are collected from areas surrounding Berhampur city in the district. One on-farm experiment was conducted in Ganjam district to evaluate the effect of integrated nutrient management on Kewda yield and growth. Three treatments were taken, i.e., T1-STBF (soil test based fertiliser)+ FYM @15kg/pit thrice, T2-STBF+FYM @15kg/pit thrice +Inoculation of OUAT (Odisha University of Agriculture & Technology) Cosortia bio-fertiliser to the rhizosphere on the date of planting, T3- Fym 20kg/pit/year (control). Results revealed that T2 significantly enhanced flower yield, producing 44 flowers per plant with a fresh weight of 21 kg/100 flowers, which was 53% higher compared to the control. Plant girth (18.4 cm) and number of leaves (10.0) were also higher under T2 than in the control (16.4 cm girth and 5.2 leaves). The findings indicate that integrated application of STBF, FYM, and OUAT consortia biofertilizers can substantially improve kewda productivity and growth under farmer field conditions in Ganjam district.

Plant Rhizodeposition and Role in Sustainable Agriculture | Chapter 11 | Research Advances and Challenges in Agricultural Sciences Vol. 4

Plants exude a large proportion of their photosynthetically assimilated carbon from their roots to soil. These root-released organic carbon compounds can significantly influence the chemical, physical and biological processes in the rhizosphere. Rhizodeposition is defined as all material lost from plant roots, including water-soluble exudates, secretions of insoluble materials, lysates, dead fine roots, and gases, such as CO2 and ethylene. The high molecular weight rhizodeposits (e.g. mucilage, cellulose) which are not easily used by microorganisms make up the majority of carbon released from the root. However, the low molecular compounds (e.g. root exudates) are more diverse and have lot of potential functions. Root exudate compounds can be categorized into organic acids, amino acids, proteins, sugar, phenolics and other secondary metabolites which are more easily used by microorganisms. Root secretes mucilage, a viscous insoluble polysaccharide-rich substance, which aids in lubricating and protecting the root. Root volatile organic carbons have role in below ground plant interactions. The border cells released from root cap act as root extracellular traps for root pathogens. Plants have passive and active transports mechanisms to secrete these rhizodeposits into the rhizosphere. Root exudation pattern can be affected quantitatively and qualitatively by different physical, chemical, and biological factors. The amount of root exudates varies with plant species, the cultivar, and age of plants, soil properties, and stress factors. Rhizodeposits play an important role in soil and plant health by triggering various rhizosphere processes like nutrient solubilization, signaling for symbionts and pathogens, metal detoxification, promotion of soil aggregation, building of microbial communities and soil organic matter turn over etc., Hence, next-generation field management requires the promotion of microbial biomass formation through plant rhizodeposition to maintain healthy soils, ecosystem and climate.

Characteristics of Rhizosphere Bacteria of Sugarcane (Saccharum spp.) Grown on Acrisol and Ferrasol Soils of Dong Nai Province, the Southeast of Vietnam | Chapter 8 | Emerging Issues in Agricultural Sciences Vol. 7

 The study proposed to investigate variety, population dynamics of nitrogen obsession and phosphate solubilization bacteria in rhizosphere of sugarcane refined in acrisol and ferrasol soils of Dong Nai province, the Southeast of Vietnam. Nitrogen total, dissolved phosphorus and basic carbon of the soil were determined by utilizing colorimetric method and design described by Walkley-Black. Nitrogen obsession and phosphate solubilization bacteria were isolated on Burk's nitrogen free and NBRIP publishing. Identification, SNPs and nucleotide diversity of picked bacterial strains were based on 16S rDNA sequences accompanying primers 27F and 1492R, SeqScape@Software and Theta (θ) described by Halushka et al.. Validation of nitrogen obsession of strains was carried out by hide presence of nifH accompanying Pol primers. The research found that rhizosphere of sugarcane refined in Dong Nai province were slightly sour, poorly nutrient and had different plant growth advancing bacteria. pH, nitrogen total and organic matter component of the soils were three essential determinants influencing two together populations of nitrogen obsession and phosphate solubilization bacteria in the soils while available planet seen at dawn in the soils was closely accompanying with nitrogen obsession bacteria society rather than phosphate solubilization bacteria populace in the soils. Thirty-one strains unique expressed volume of fixing nitrogen, solubilizing phosphate and biosynthesizing IAA. Fourteen of thirty-one strains were deepened nifH. Twelve of thirty-one strains accompanying high ability of plant growth publicity were identified as species of Bacilli, Acidobacteria, Bacteroides and Betaproteobacteria place Bacilli had the highest Pis and thetas. Bacillus megaterium B6 unique from ferrasols and Sphingomonas sp. P14 isolated from acrisols displayed as potential candidates and were proposed expected tested their skill to promote plant tumor of sugarcane grown in acrisol and ferrasol soils of Dong Nai province.

Commercial Production and Use of Carbon Nanotubes-added Biofertilizer | Chapter 11 | Research Developments in Science and Technology Vol. 9

Carbon nanotubes (CNTs) are a significant class of nanomaterials with special properties that have a wide range of uses in industries like electronics, material science, and medicine. However, the insolubility of CNTs in aqueous conditions and safety worries prevent their usage in agriculture.

Their agricultural utility may be increased by the capacity to separate and dissolve isolated CNTs. Crop yields in dry environments can be increased by using commercially available water soluble CNTs-added biofertilizer. It includes nanoparticles with distinctive physicochemical characteristics, including large surface areas, high reactivity, suitable pore sizes, and particle morphologies, which can assist in supplying nutrients to plants to enhance growth and yields. The commercial production and applications of biofertilizer with carbon nanotubes are highlighted in this chapter.
