Abstract: This study examined the relationship between perceived COVID-19 susceptibility, health risk perception, risk avoidance, and travel intentions, and explored the moderating role of government trust. The study data were collected through both Tencent Questionnaire (113) and field research (507) methods. The results showed that perceived susceptibility significantly influenced health risk perception and risk avoidance, which in turn significantly influenced travel intentions. Health risk perception and risk aversion partially mediated the effect of perceived susceptibility on travel intentions, respectively, and the chain mediation relationship between them was supported. Government trust had a significant moderating effect between perceived susceptibility affecting health risk perception, and health risk perception and travel intentions. This study provides new insights into the factors influencing tourists' travel intentions in a global public health context and contributes to the recovery of the tourism economy and the development of marketing strategies for destinations in the post-pandemic era.

Abstract: Metropolitan areas are an inevitable outcome of urbanization development. The countryside is the key problem restricting the quality of urbanization development in such areas. Rural tourism-driven revitalization is of considerable importance for the integrated development of urban and rural areas in metropolitan areas. Based on comprehensive development level and coupling coordination degree models, we used the fuzzy comprehensive evaluation method to calculate the coupling and coordinated development level of rural tourism and revitalization in the metropolitan area of Xi'an in 2021. Furthermore, we explored the dynamic mechanism of coordinated development in combination with typical cases. The results indicate the following: (1) In 2021, the overall level of rural tourism development was good, and the spatial difference exhibited a decreasing phenomenon from the core circle to the outer circle. (2) The coupling and coordination degree of rural tourism and revitalization is generally in a balanced state, which indicates that the core circle is superior to the peripheral circle in space. (3) The combined effect of “supply-demand-guarantee” is an important driving mechanism for the coordinated development of rural tourism and revitalization in the metropolitan area, in which “supply” is the basic factor for the coordinated development, “demand” is the core factor for the improvement of its coupling coordination level, and “guarantee” is the supporting factor for its sustainable development. This study enriches the theory of rural revitalization in metropolitan areas to a certain extent and provides new insights for improving the quality of urban and rural integrated development in metropolitan areas.

An investigation on the effect of different levels of nitrogen in combination with nano urea on growth, yield and quality of crossandra (Crossandra infundibuliformis L.) cv. Lakshmi was carried out in the Floriculture unit, Department of Horticulture, Faculty of Agriculture, Annamalai University, Chidambaram during the year 2022-2024. The experiment was laid out in Randomized Block Design with 14 treatments and 3 replications. Among the different treatments, the treatment T5 (100% PK + 75% N through urea + 0.4% Nano urea (3 sprays)) resulted in increased growth attributes such as plant height (85.21 cm), stem girth (7.95 cm), number of branches/plant (24.51), number of leaves/plant (99.29), leaf area (95.41 cm2) and chlorophyll content (0.840 mg/g). With regards to yield attributes, the treatment T8 (100% PK + 50% N through urea + 0.4% Nano urea (3 sprays)) showed early spike emergence (37.54 days), time taken for 1st flowering (44.83 days) with an increase in number of spikes/plant (36.27), spike length (14.21 cm) and number of flowers/spike (39.21). 100 flower weight (8.62 g), flower yield/plant (51.03 g), flower yield/plot (974.76 g/plot), estimated flower yield/ hectare (32.49 q/ha) and quality attributes like xanthophyll content (69.42 mg/g), carotenoid content (57.76 mg/g), shelf life of flowers (74.88 hours), longevity of flower in the plant (95.52 hours) and flowers with an excellent quality of visual scoring (9.16) were also observed the maximum in the treatment T8. The treatment control (T1) had the lowest value for all the growth, yield and quality attributes. Hence, it is concluded that the treatment T8 (100% PK + 50% N through urea + 0.4% Nano urea (3 sprays)) was found to be the best combination for improving the growth, yield and quality of crossandra cv. Lakshmi.

Rice cultivation faces challenges such as declining soil health, nutrient depletion, and environmental pollution caused by industrial waste. The integration of bio-digested bone sludge compost industrial waste with other organic and inorganic fertilizers needs to be studied for achieving long-term sustainability of agricultural systems. Therefore, a field experiment took place during the 2022 at the Annamalai University, Tamil Nadu, India with an aim to examine the impact of incorporating bone sludge, a by-product of the ossein industry, as a fertilizer in conjunction with various other organic fertilizers, including bone sludge compost, pressmud compost, poultry manure compost, goat manure compost, and farmyard manure, on the growth, yield, nutrient uptake and post-harvest soil status of rice. The experiment was laid out in a randomized block design with three replications. The experiment comprised eight treatments. The results of the experiment revealed that among the different treatments tested, application of bone sludge compost @ 5 t/ha + pressmud compost @ 5 t/ha along with balance N and K through fertilizers excelled all treatments and gave significantly higher nutrient uptake of 151.10, 63.51, 147.05 kg/ha of nitrogen, phosphorous, potassium respectively also recorded highest post-harvest soil available nutrient of 222.98, 110.23, 276.21 kg/ha of nitrogen, phosphorous, potassium when compared to other treatments. The results of this study underscore the efficacy of utilizing bone sludge compost and pressmud compost, coupled with meticulous fertilizer management, to augment nutrient assimilation in rice crops and bolster soil fertility post-harvest. These findings present compelling evidence for the adoption of sustainable agricultural strategies aimed at enhancing crop productivity while concurrently preserving soil health.

Horticultural plants such as the bitter gourd (Momordica charantia L., family Cucurbitaceae) have a special significance as a vegetable in the kitchen and offer health benefits. Bitter gourd is cultivated in several tropical regions of Asian countries and in parts of Africa, Central North America, South North Asia, Singapore, Japan, etc. The main objective of this study is to develop a modified and validated high performance method for the quantification of charantin. Bitter gourd is rich in various phytomolecules, including charantin as an antidiabetic agent. Charantin is one of these phytomolecules that acts as an antidiabetic agent in type 2 diabetics. Charantin has a high molecular weight so that it is easily digested when taken orally. A validated and modified high performance liquid chromatography method was used for the quantification of charantin in bitter gourd fruits. Bitter gourd plants transplanted in Kharif 2023 from Mandsaur University Nursery, Mandsaur Campus were used for modification of extraction parameters and for carrying out the validated protocol in Kharif 2023. The fruits were harvested 60-65 days after planting in June/July 2022. Charantin extraction was done using methanol in Soxhlet and analysis was done using modified high performance liquid chromatography for quantification. C18 columns as stationary phase and methanol:water (98:2) were used for separation and quantification of charantin. Validated method for the analysis and separation of charantin in dry powder of bitter gourd fruits. Analysis and quantification were performed using the methanolic extract and yielded a content of 200-600 ug/g dry fruit weight. The high charantin variety can be used for further breeding purposes or directly for product formulation and basic clinical trials if required.

Cochliobolus miyabeanus is an important plant pathogen which causes a very common and widespread brown spot disease in rice, that may result in a severe reduction in the crop yield. The current studies were carried out to search out the antifungal potential of the bacterial isolates from the rhizospheric region of Daucus carota against brown spot fungus, C. miyabeanus. Isolation of rhizospheric bacterial isolates was done from carrot grown field of district Jaunpur in month of January, 2023. Experiment work has been done in Department of Biotechnology, Veer Bahadur Singh Purvanchal University, Jaunpur in 2023 from the month January to November. All bacterial isolates were tested for antifungal activity against brown spot fungi. Isolates were screened for their antifungal activities against brown spot fungus for further studying plant growth promoting, biochemical and morphological attributes. Isolates, CVO-7 and NBRI-O-2 showed efficient antifungal activity against test organism and also showed some plant growth promoting attributes that can further reduce the virulence of C. miyabeanus by enhancing availability of essential and trace elements for the plant. Both the isolates were characterized at a molecular level by using 16S rRNA gene sequencing and sequences of 16S rDNA segment were submitted to the NCBI GenBank database with the accession numbers OR775577 (Bacillus subtilis ss5cvo7) and OR775572 (Bacillus proteolyticus ss2nbrio2).

The domestic demand for vegetable oils and fats has been rising rapidly, @ 6 per cent per annum, but our domestic output has been increasing at just about 2 per cent per annum. In India, the average yield of most oilseeds is extremely low as compared to other countries of the world. Therefore, field experiments were conducted at an experimental farm, Annamalai University during the Kharif season in 2022 and 2023 to study the effect of nitrogen and sulphur on the growth and yield of groundnut. The experiment consisted of sixteen treatments and was laid out in a factorial randomized block design with three replications. The treatment consisted of Factor A (nitrogen levels): 0, 17, 25, 34 Kg N/ha and Factor B (sulphur levels): 0, 20, 40, 60 Kg S/ha. Among the different nitrogen levels tried, application of 34 kg N/ha registered higher growth and yield attributes and yield of groundnut. Regarding sulphur levels, maximum growth, yield attributes and yield of groundnut were influenced by the application of sulphur @ 60 kg/ha (S4). With respect to various interaction effects, the application of 34 kg N/ha along with 60 kg S/ha has a significant effect on growth and yield attributes which ultimately results in the maximum yield of groundnut.

The treatment consisted of Factor A (nitrogen levels): 0, 17, 25, 34 Kg N/ha and Factor B (sulphur levels): 0, 20, 40, 60 Kg S/ha. Among the different nitrogen levels tried, application of 34 kg N/ha registered higher growth and yield attributes and yield of groundnut. Regarding sulphur levels, maximum growth, yield attributes and yield of groundnut were influenced by the application of sulphur @ 60 kg/ha (S4). With respect to various interaction effects, the application of 34 kg N/ha along with 60 kg S/ha has a significant effect on growth and yield attributes which ultimately results in the maximum yield of groundnut.\u0000","PeriodicalId":10786,"journal":{"name":"Crop research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141370167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The disposal of fly ash from coal-fired power stations poses significant environmental challenges, particularly near thermal power plants like the Kolaghat Thermal Power Station in West Bengal, India. Therefore, a study was conducted in 2022 – 2023 at the Department of Zoology, PanskuraBanamali College, West Bengal to study the impact of fly ash contamination on soil, water, and crops within a 5km radius of the plant. Heavy metals such as Cu, Fe, Pb, Zn, and Mn were analysedthrough AAS in soil, water, shoot, root, and rice endosperm.The bioabsorption coefficient, bioconcentration factor, and translocation factor for heavy metalbioaccumulation were examined. The impact of different concentrations of fly ash on crop yield was determined by measuring the mean shoot length, mean seed stalk length, mean number of seeds per stalk, and mean dry weight of endosperm per stalk.The study revealed the highest heavy metal concentrations in soil, with Fe, Mn, Cu, Zn, and Pb being the most abundant. Plants exhibited hyper-accumulation of Cu, Zn, and Mn, while Pb and Fe showed moderate translocation. Rice grown with fly ash showed optimal growth at 1% concentration, similar to 5%, but higher concentrations reduced yield. Future research should focus on plant metal absorption, phytoremediation, and bioremediation for effective mitigation of fly ash contamination, emphasizing thorough investigations.
