Abstract
Agriculture sector is facing a lot of constraints such as climate change, increasing population and the use of chemicals, and fertilizers which have significant influence on sustainability. The excessive usage of chemical fertilizers and pesticides has created a significant risk to humans, animals, plants, and the environment. To reduce the dependency on chemical fertilizers and pesticides a biological-based alternative is required. Seaweeds are essential marine resources that contain bioactive compounds and they have several uses in agriculture. The use of seaweed extracts in agriculture can mitigate stress, enhance nutrient efficiency, and boost plant growth. The use of seaweed extracts and their components activate several signaling pathways and defense-related genes/enzymes. In this review, an attempt has been made to explain how seaweed extracts and their bioactive components induce tolerance and promote growth under stress conditions.

AMF colonization affects allelopathic effects of Zea mays L. root exudates and community structure of rhizosphere bacteria. FRONTIERS IN PLANT SCIENCE 2022; 13:1050104. [PMID: 36507415 PMCID: PMC9731342 DOI: 10.3389/fpls.2022.1050104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Accepted: 11/03/2022] [Indexed: 06/17/2023]
Abstract
Arbuscular mycorrhizal fungi (AMF) widely exist in the soil ecosystem. It has been confirmed that AMF can affect the root exudates of the host, but the chain reaction effect of changes in the root exudates has not been reported much. The change of soil microorganisms and soil enzyme vigor is a direct response to the change in the soil environment. Root exudates are an important carbon source for soil microorganisms. AMF colonization affects root exudates, which is bound to have a certain impact on soil microorganisms. This manuscript measured and analyzed the changes in root exudates and allelopathic effects of root exudates of maize after AMF colonization, as well as the enzymatic vigor and bacterial diversity of maize rhizosphere soil. The results showed that after AMF colonization, the contents of 35 compounds in maize root exudates were significantly different. The root exudates of maize can inhibit the seed germination and seedling growth of recipient plants, and AMF colonization can alleviate this situation. After AMF colonization, the comprehensive allelopathy indexes of maize root exudates on the growth of radish, cucumber, lettuce, pepper, and ryegrass seedlings decreased by 60.99%, 70.19%, 80.83%, 36.26% and 57.15% respectively. The root exudates of maize inhibited the growth of the mycelia of the pathogens of soil-borne diseases, and AMF colonization can strengthen this situation. After AMF colonization, the activities of dehydrogenase, sucrase, cellulase, polyphenol oxidase and neutral protein in maize rhizosphere soil increased significantly, while the bacterial diversity decreased but the bacterial abundance increased. This research can provide a theoretical basis for AMF to improve the stubble of maize and the intercropping mode between maize and other plants, and can also provide a reference for AMF to prevent soil-borne diseases in maize.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 837:155593. [PMID: 35490802 DOI: 10.1016/j.scitotenv.2022.155593] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/26/2021] [Revised: 04/20/2022] [Accepted: 04/25/2022] [Indexed: 06/14/2023]
Abstract
Agronomical providence of nanoparticles in enhancing food productivity has brought new revolution in agricultural sector. However, the comprehensive ingenuity of their synergetic impact on environment and living flora and fauna is still poorly explored. The current study endeavours to tackle this apprehension by systematically exploring the agronomical paradigm of six different types of C-dots derived from natural biomass and plastic waste on the four different types of seeds viz. black chick peas (Cicer arietinum), barley (Hordeum vulgare), mung beans (Vigna radiata) and wheat (Triticum aestivum) at room temperature. C-dots have displayed a dose responsive effect (250 to 5000 mg/L) on the growth of chosen seeds, including the elongation of root length and coleoptile length. The development of seedlings under atmospheric conditions exhibited excellent physiological stability in presence of synthesized C-dots for all types of seeds with concentrations as high as 3000 mg/L for dry seed. The direct exposure of C-dots resulted in enhanced growth as compared to the water exposure and considered as the most important novel aspect of present work. The developed C-dots provide more nutrient content and easy penetration to the seeds due to their enhanced surface area and very small size. The germination and Vigor index have also been augmented in presence of C-dots after 7 days of exposure. C-dots have affected the chlorophyll content in mung beans as a function of time and concentration. The developed C-dots possess excellent biocompatible behaviour and help in the complete growth of the different types of seeds which suggest their enhanced utilization in the agronomical field. This is one of the detailed studies, which explore the impact of C-dots on widely used food crops with the non-toxic and biocompatible C-dots. The information achieved herein will allow the usage of C-dots as a capable nanopriming agent for the natural germination of seeds.

Abstract
In Istanbul, which is surrounded by the sea on 3 sides, thousands of tons of seaweed that have formed naturally every year are washed ashore. In this study, the usability of these seaweeds which are landfilling already in fertilizer production was discussed. Liquid fertilizer production was carried out using 3 different physical and 4 different biological methods, and the produced fertilizers were diluted in 5 different ratios (1%, 10%, 25%, 50%, and 100%) and applied to cress seed. The effect of each fertilizer and its concentration on seed germination, plant length, number of leaves, and soil moisture-holding capacity was studied. The data obtained were analyzed using Response Surface Methodology (RSM). The results showed that if seaweed was fermented with anaerobic seed sludge for 15 days and applied to the plant by diluting it to 15-25%, plant growth will be supported at an optimum level. It has also been shown that if the seaweed was fermented with yeast culture for 18 days and fed with a concentration of >90%, the moisture-holding capacity of the soil could be increased by up to 27%.
