These species are facing escalating threats, from direct harms such as overhunting to indirect pressures like habitat degradation and climate change. This systematic review explores the challenges confronting marine megafauna, examines current conservation strategies, and explores innovative future strategies. Current efforts, while beneficial, often fail to address socio-economic factors and cumulative threat impacts, and lack robust long-term outcome evaluations. Potential strategies, leveraging emerging technologies, climate-smart conservation, sustainable blue economies, and rights-based approaches, are discussed. Despite their potential, these strategies present challenges, necessitating further interdisciplinary, social, cumulative impact, and long-term monitoring research. Understanding and addressing these aspects is essential for the development of holis...

In recent years, nanotechnology has emerged as a pivotal tool, redefining traditional agricultural paradigms. This comprehensive review delves into the multifaceted implications and applications of nanotechnology within agriculture, providing a holistic view of its past, present, and future roles. Historically, nanotechnology's initial foray into agriculture sought to tackle prevalent challenges, from pest control to soil fertility. Despite some early obstacles, this merger has since showcased myriad successful applications, underscored by targeted and efficient solutions that significantly enhance crop yield and food quality. The present-day agricultural landscape is punctuated by nano-fertilizers ensuring optimal nutrient uptake, nanopesticides targeting pests with minimal off-target effects, nanosensors enabling precision agriculture, nano-based ...

This review examines the application and impacts of mulch installation techniques on Indian horticulture, with a focus on understanding different mulch types, traditional and modern techniques, advantages, potential impacts on crop growth and yield, and environmental implications. The introduction elucidates the definition and historical importance of mulching in horticulture and sets the objective of the review: to comprehensively assess various mulch installation techniques and their impacts on Indian agriculture. The subsequent sections delve into the different types of mulches used in Indian horticulture, categorizing them into organic, inorganic, and biodegradable materials. Each type is discussed in detail, including its benefits and concerns, providing a holistic understanding of the materials available to farmers. Traditional mulching techniques, su...

Micronutrient deficiencies, also known as "hidden hunger," continue to affect many people around the world, particularly in underdeveloped countries. This presentation emphasises the need of biofortification in solving this worldwide health issue. Biofortification tries to improve the level of important micronutrients such as iron, zinc, vitamin A, and iodine in edible plant portions by using traditional breeding techniques or current biotechnological procedures. Iron-fortified beans, zinc-enhanced rice, vitamin A-rich sweet potatoes, and iodine-enriched crops are all examples of successful biofortified crops. To maximise their impact, biofortification programmes must be integrated with nutrition education and agronomic practises, according to the abstract. Governments, research institutes, non-governmental organisations, and th...

Fractionation provides information about the chemistry of B and quantifies its bioavailability. Therefore, a pot experiment was performed during the 2019 pre-kharif season in acid soil to study soil B fractions and response of green gram (Vigna radiata L.) to B application. Lime is applied to such soils with the primary objective of increasing the productivity of crops by enhancing the availability of native and applied plant nutrients. On the contrary, availability of B in soil was increase due to liming. The treatments comprised of five levels of soil applied B (0, 0.5, 1.0, 1.5 and 2.0 mg B kgā1) and two levels of lime, lime and no lime was used. The experiment was laid out in factorial randomized block design (FRBD) with three replications. The soil and pant growth parameters were recorded at a regular interval of 15 days after sowing, and at harvest. All ...

DGGS-4). Study Design: This experiment was conducted through a completely randomized design with 10 treatments and 3 replications. Place and Duration of Study: The research was conducted at the Department of Soil Science and Agricultural Chemistry, Central Agricultural University, Imphal between February 2019- November 2019. Methodology: Available phosphorus content in soil was estimated spectrophotometrically by Bray and Kurtz No. 1 method, the Active Phosphorus was determined by the addition of Saloid-bound phosphate, Aluminum phosphate, iron phosphate, and calcium phosphate, and total Inorganic P is the summation of all the inorganic forms of P. Total Phosphorus (Total P) in Soil was estimated by using Murphy-Riley solution and 5M NaOH and the intensity of yellow color was read at 730 nm in a spectropho...

All the three cancers are amenable to prevention, early detection, and treatment through which the morbidity and mortality due to these cancers can be reduced. This pilot study was conducted to assess the operational feasibility of the national cancer screening guidelines. Method: This study was conducted in the Dibrugarh district of Assam in seven tea garden hospitals which serve as the primary health centers for the tea estate population in the Northeast region of India. The study intervention was a three-day training package designed to train primary care physicians in population-based screening for oral, breast, and cervical cancers. Knowledge evaluation and skill assessment were performed with a validated questionnaire and checklist, respectively. Results: Pre and posttraining knowledge assessment showed significant gain in the knowledge levels of the participants in all topics. The greatest knowledge increase was seen in breast cancer (96.3%), followed by cervical cancer (57.5%), oral cancer (35.5%) and general cancer-related information (16.7%). The skill assessment done for each participant individually at the end of the training indicated a need for retraining all participants in breast cancer screening. Conclusion: The learnings from this study will be of great help in scaling up the capacity building programme for cancer screening when the nation-wide population-based cancer screening programme will be rolled out in the country.
