Fecundity is a crucial parameter in fisheries, serving as an indicator of the reproductive potential of fish populations. Understanding the fecundity of Schizopyge niger is vital for estimating the number of offspring produced during the spawning season, a key factor in the stock assessment of species. Evaluating fecundity also plays a significant role in determining the commercial viability of the stock, understanding its life history, supporting aquaculture practices, and ensuring effective fishery management. 30 samples were collected once every month from September, 2022 to August, 2023 and yielded a total of 217 females and 143 males. A total of 20 gravid females were collected during the spawning season (February-March) from Dal lake, Kashmir and fecundity was estimated using gravimetric and actual counting methods. The absolute fecundity ranged from 6,318 to 19,375 eggs, while the relative fecundity ranged from 26.74 to 60.34 eggs per gram of body weight, with a mean of 46.96 eggs/g. A strong positive correlation was observed between fecundity and body size parameters, particularly ovary weight (R²= 0.6601). The ova diameter during entire study period ranged from 0.21 mm to 2.66 mm, showing a unimodal distribution, which suggests that S. niger is an annual spawner with a single spawning event each year. These findings serve as a baseline for the conservation and broodstock management of S. niger in the Dal Lake, Kashmir.","PeriodicalId":15023,"journal":{"name":"Journal of Advances in Biology & Biotechnology","volume":"28 1","pages":"527-535"},"PeriodicalIF":0.0,"publicationDate":"2025-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147920105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optimizing nitrogen application is instrumental in determining the environmental sustainability and economic feasibility of a farming system, making its management a top priority. In addition, the weed problems in dry direct-seeded rice account for the yield reduction and diminish the market value by reducing the product quality and raising the postharvest cost. Considering this, the present investigation was accomplished at MRCFC, SKUAST-K, Khudwani during Kharif 2022 and 2023. The experiment encircled the employment of four nitrogen levels: 0 kg N ha-1(N0), 60 kg N ha-1 (N1), 120 kg N ha-1 (N2), and 150 kg N ha-1 (N3). Additionally, seven weed management practices were employed encircling Pendimethalin at 1 kg ha-1 (3-4 DAS) + 2,4-D at 0.75 kg ha-1 (20 DAS), penoxsulam at 22.5 g ha-1 (12-15 DAS), Pyrazosulfuron combined with Pretilachlor at 30 g + 0.75 g ha-1 (3-4 DAS), Bensulfuron Methyl combined with Pretilachlor at 30 g + 0.75 g ha-1 (3-4 DAS), and Triafamone combined with Ethoxysulfuron at 40 g + 20 g ha-1 (12-15 DAS). The treatments also included a weedy check and a weed-free control. The experiment was designed in line with the factorial randomized complete block design (RCBD) possessing three replications. The acquired results elucidated a considerable increase in growth attributes such as leaf area index in response to various nitrogen levels as well as weed management approaches. Employment of nitrogen @ 150 kg ha-1 and Triafamone + Ethoxysulfuron (40+20 g ha-1) application, in addition to weed-free treatment, recorded the highest values for Leaf area index during 2022 and 2023.","PeriodicalId":15023,"journal":{"name":"Journal of Advances in Biology & Biotechnology","volume":"28 1","pages":"408-417"},"PeriodicalIF":0.0,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147904837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The chemicals tested, were Naphthalene Acetic Acid (NAA), Urea, and Ethephon and were applied after petal fall. The findings revealed that NAA (30 ppm) significantly enhanced vegetative parameters such as plant height, shoot elongation, and leaf area. Both NAA and ethephon effectively reduced fruit set and overall yield while improving fruit quality traits, including fruit size, weight, and coloration. Additionally, ethephon (150 ppm) accelerated fruit maturation by 7–8 days.

This review examines various seed priming methods, including hydropriming, osmotic priming, halo-priming, and nanopriming, and their application across diverse crops. These techniques enable seeds to withstand abiotic stresses such as drought, salinity, and heat, which are increasingly critical due to climate change and resource limitations. Research highlights the effectiveness of hydropriming in wheat, where soaking seeds in water enhances germination rates and uniformity, particularly under saline conditions. Similarly, halopriming with potassium nitrate (KNO₃) or sodium chloride (NaCl) solutions improves salt stress resilience in tomato plants, increasing root length and seedling vigor. These findings illustrate the ability of seed priming to support crop establishment in challenging environments, including arid and semi-arid regions. Seed priming also offers broader agricultural and environmental benefits. Techniques like on-farm priming are cost-effective, eco-friendly, and accessible to farmers with limited resources, making advanced practices more widely adoptable. By reducing reliance on chemical inputs and enhancing resistance to soil-borne diseases, seed priming promotes sustainable farming practices. Moreover, advanced methods such as nanopriming provide precise delivery of nutrients and growth agents, opening avenues for more efficient agriculture. Future research should focus on optimizing priming protocols for specific crops and environments, assessing long-term impacts on yield, soil health, and crop quality, and developing solutions tailored to climate extremes and marginal lands. Additionally, exploring biopriming with beneficial microorganisms could further enhance plant health and resilience. Seed priming is a transformative agricultural tool with the potential to boost productivity, mitigate the impacts of climate change, and ensure food security. Expanding its adoption through strategic research, supportive policies, and farmer education will be critical to maximizing its global impact.

The mean concentration of Zinc (Zn) in AMAC were 0.88 ± 0.35mg/kg and 2.04 ± 0.57mg/kg in Kuje Area Council respectively. Results showed that the concentration of Zinc (Zn) in cow hide (Ponmo) from AMAC was two times as high as cow hide (Ponmo) from Kuje Area Council. The mean concentration of Zinc (Zn) in cow hide in both Area Councils were two times as high as the Food and Agricultural Organization Standard unit for Zinc(Zn), which is 0.03mg/kg -1.0mg/kg. However, potential accumulation may depend on the frequency of consumption or exposure. In contrast to many studies the samples had alot of nutritional value. Proximate analysis showed that the ponmo samples for Kuje had 54% proteinand 34.68% carbohydrate, moisture 5.3%, crude lipid 2.3%, ash 2.7%, fibre 0.82% while ponmo samples for AMAC had 51.4% protein, 36% carbohydrate, 5% moisture, crude lipid 4.3%, ash 2.1% and fibre 1.1% which suggests that Ponmo has some level of nutrient especially rich in protein and carbohydrate and low in fibre content. Cowhides from AMAC and Kuje Area Councils contain significant amount of zinc, which exceeded the standard limit and could pose a potential health risk to consumers depending on the frequency of consumption. Hence the need for monitoring of this metal concentration to avoid excessive bioaccumulation that could be harmful to health. This study also showed that cowhides is rich in some nutrients especially protein and carbohydrates and can be a substitute for meat protein.","PeriodicalId":15023,"journal":{"name":"Journal of Advances in Biology & Biotechnology","volume":"96 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135218509","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}

This is to assess the potential impact of climate change on wheat production under different irrigation treatments using the DSSAT-CERES wheat simulation model and climate change scenarios; to determine the best sowing date to be used as an adaptation strategy under climate change scenarios. The model effectively simulates wheat yield, with a high goodness of fit and d-Stat value, and low root mean square per observation, resulting in an overall goodness of fit of average 13.8 kg/fed. The model's performance was satisfactory, with high R2 and d-Stat values and low RMSE/obs, with overall values of 0.830, 0.951, and 2.3 mm, respectively for water consumption. The CERES-Wheat model accurately simulates wheat yield and water consumption, allowing us to assess climate change's impact on wheat yield in 2030 and 2040. The study shows a decrease in solar radiation (SR) by 1.9 and 2.1 MJ/m2/day in 2030 and 2040, while maximum temperature increases by 1.5 and 1.9°C due to climate change, and minimum temperature decreases by 1.8 and 2.3°C in 2030 and 2040. This results in an increase in potential evapotranspiration (PET) by 0.2 and 0.3 mm. The study predicts that season length will shorten in 2030 and 2040 due to temperature increases. In 2030, it will be reduced by 2, 4, and 4 days under different treatments. In 2040, it will be lower, with reductions of 3, 5, and 5 days. The study found that wheat yield losses would be lowest under the first sowing date and irrigation treatment, while the highest reductions were found under the third treatment. Climate change will reduce wheat water consumption due to shorter growing seasons and heat stress, with the lowest reductions occurring in 2030 and 2040 at 8 and 18%, respectively. The highest reductions in wheat yield were observed under the third sowing date and irrigation treatment. We suggest planting wheat in November, using full irrigation to prevent high-yield losses, and implementing adaptation strategies to reduce wheat plant vulnerability to climate change risks.","PeriodicalId":15023,"journal":{"name":"Journal of Advances in Biology & Biotechnology","volume":"505 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135617666","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 attiéké enriched with legume flours was prepared in different proportions of 10%, 15% and 20%. The samples were produced by incorporating the flour of the three legumes into the cassava paste in a single step (fermentation). The ferment content and fermentation time were 12% and 24 hours respectively. The chemical and sensory characteristics of the cowpea, voandzou and common bean enriched attiéké formulations were determined using standard methods. The results showed that the protein (1.13-9.93%), fat (0.06-2.06%), ash (0.1-1.13%), fibre (2-6.33%) and energy (353.747-372.06 Kcal/100 g) contents of the legume-enriched attiéké increased significantly with the cowpea, voandzou and common bean content. In addition, the addition of legume meal induced a significant increase in pH from 4.6 to 4.9. The incorporation of 10, 15 and 20% legume flours changed the appearance, aroma, taste, colour, and overall acceptability of the enriched attiéké compared to the control attiéké which were less appreciated by consumers. Flours with 10% legumes added to the cassava paste before the fermentation process yielded the most acceptable food compared to flours with 15 and 20% legumes added.

 Place and Duration of Study: Nana, Petit Bouaké, Subiakro and Zatta rice-growing lowlands in the Yamoussoukro district (Central Côte d’Ivoire) from May 2021 to April 2022.
 Methodology: Seed-eating birds were surveyed using the line transect method between 6.30 am and 6.30 pm. At each site, four surveys were carried out per month.
 Results: In total, 22 species of seed-eating birds belonging to six families and three orders were inventoried in the rice-growing lowlands of the Yamoussoukro district. Among them, Village weaver Ploceus cucullatus, Red-headed Quelea Quelea erythrops and Bronze Mannikin Spermestes cucullata were the predominant species. Five other species, Red-eyed Dove Streptopelia semitorquata, Magpie Mannikin Spermestes fringilloides, Northern Grey-headed Sparrow Passer griseus, Yellow-mantled Widowbird Euplectes macroura and Black-winged Bishop Euplectes hordeaceus were regular in these lowland rice fields. Numbers of these seed-eating birds were highest at the Subiakro site and at the spike development and maturation of the rice. In addition, their numbers were highest between March and October and lowest between November and February.
 Conclusion: This study indicates that eight seed-eating birds are likely to cause significant damage to rice crops, but their pressure could be reduced by planning harvests between November and February.","PeriodicalId":15023,"journal":{"name":"Journal of Advances in Biology & Biotechnology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135830227","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}
