ABSTRACT
Strawberry cultivation represents a significant sector within the agriculture industry. The use of nitrogen (N), calcium (Ca), and nano fertilizers has emerged as an essential practice to improve both the yield and quality of strawberries. This comprehensive review aims to explore the multifaceted influence of these fertilizers on Fragaria × ananassa Duch, encompassing growth, quality, and environmental considerations. The study begins with an examination of historical perspectives and existing research, identifying gaps in the literature. The methodology includes a rigorous selection process for studies, with data extraction, quality assessment, and statistical analysis. The effects of N, Ca, and nano fertilizers on growth yield are thoroughly examined, considering their combined and individual contributions. The quality of strawberries is assessed based on physical appearance, nutritional content, and sensory characteristics, highlighting the role of these nutrients in color development, size, texture, vitamin content, sugar-acid balance, flavor, and aroma. The environmental impact is another critical aspect, exploring the effect on soil quality, including nutrient leaching, soil structure, microbial activity, and long-term health. The impact on surrounding ecosystems considers aquatic and terrestrial effects, biodiversity considerations, and the associated sustainability considerations. These encompass resource efficiency, environmental compliance, life cycle analysis, and integration with sustainable agricultural practices. Findings indicate that while N, Ca, and nano fertilizers significantly enhance growth and quality, careful management is essential to mitigate potential environmental concerns. The application of nano fertilizers presents promising opportunities for precise nutrient delivery, promoting efficiency, and sustainability. The review concludes by emphasizing the importance of continued research, innovation, and responsible management of these fertilizers in achieving a harmonious balance between productivity, quality, and environmental stewardship. The insights provided in this review contribute valuable knowledge to both scientific and agricultural communities, offering guidance for future research and best practices in strawberry cultivation.
ABSTRACT
Chemical fertilizer usage has been a long-drawn criticism because of its harmful effects on the environment and on the quality of agricultural produce. Researchers are continually looking for more productive, better solutions while retaining societal wellbeing. Effective use of nano fertilizers in place of chemical fertilizers is essential in reducing fertilizer overuse and also contribute in lowering the pollution and leaching which in turn increase the effectiveness of nutrient consumption and also increase the yield of the crop. An experiment was carried out in paddy to study the influence of Nano urea applications on growth and microbial populations in soil. The field trial used a Randomized Block Design (RBD) with eight treatment combinations and three replications. Results showed that application of STCR based N as Urea (50%) and Nano Urea (2 sprays) and Recommended dosage of N as Urea (50%) and Nano Urea (2 sprays) recorded higher plant height, Leaf Area Index (LAI), Dry matter accumulation in paddy. In addition, applications of Nano urea increased the microbial population including bacteria, fungi and actinomycetes. Combining recommended dosage of fertilisers with nano urea spray at critical stages of paddy crop increases the crop growth and microbial activity.
ABSTRACT
It aims to examine the impact of nano and non-nano fertilizers on rice quality and productivity. Rice is a staple food crop for a large portion of the global population, the use of fertilizers is essential for optimizing yields and maintaining food security. The emergence of nano-fertilizers presents new opportunities for enhancing nutrient use efficiency, plant growth, and rice quality. However, limitations in existing research, such as the lack of comparative studies and methodological inconsistencies, make it difficult to draw definitive conclusions about the relative merits of nano and non-nano fertilizers. The implementation of nano-fertilizers faces challenges related to cost, accessibility, regulatory frameworks, and public perception. Future research should focus on long-term field studies, investigating potential risks and benefits, and developing sustainable and cost-effective formulations. By addressing these challenges and knowledge gaps, this review seeks to provide a comprehensive understanding of the potential impacts of nano and non-nano fertilizers on rice cultivation and contribute to the development of sustainable agricultural practices.
ABSTRACT
The present investigation was carried out to study the effect of foliar application of nano-fertilizers N and P on yield, and the economics of wheat in Semi-arid and sub-tropical region of Central Plain Zone of Uttar Pradesh. The experiment was laid out in triplicate following a randomized block design with twelve treatments comprising foliar application semi-different doses of Nano N and P. Foliar application of 1st spray of Nano N and P at 30 days after sowing (DAS) + 2nd spray of Nano N and Zn at 45 DAS along with 75% recommended dose of fertilizers (RDF) significantly (P=0.05) increased yield and have better economics. Foliar application of nano-fertilizers leads to significant improvement of crop productivity of wheat in Semi- arid and sub-tropical region of Uttar Pradesh. Moreover, the foliar application of nano-fertilizers, i.e., Nano N has direct role in increasing yield as nutrient get easily available to plant in case of foliar spray.
ABSTRACT
While the world's population is growing exponentially, there is an alarming increase in the need for food, which might reach a record nine billion people by 2050. In order to address the issue of rising food demand, a number of initiatives are being put into place to boost crop output and safeguard them against agricultural pests. The growing population pressures agricultural civilization to develop fresh strategies for boosting crop output. For nations all across the world, the issue of poverty and malnutrition has grown to be of great concern. Progress in the agricultural sector, which provides the raw materials for the food and feed industries, is crucial for both economic development and population expansion. With economic development, the soil nutrient balances are differed. Soil fertility is important in developing countries for assisting the economy and agriculture. There is a high demand in the twenty-first century for efficient, reliable, and cost-effective systems for detecting, supplying, monitoring, and diagnosing biological host molecules and nutrients. Traditional farming methods are incapable of keeping up with the rate at which food needs are increasing, so we must rely on and incorporate nanotechnology in agriculture and related sectors. In modern agriculture, increasing agricultural productivity is impossible without the use of chemical fertilizers and pesticides; however, the majority of agrochemicals are not eco-friendly and are thus harmful to human health. Nanotechnology is a novel technique for improved and sustainable agricultural production and also harbours a good capacity to bring novel alterations in the agricultural systems. Nanotechnology introduces new technologies and materials for use in molecular biology for the identification of plant pathogenic microorganisms. By bringing novel methods for distributing nutrients through nano fertilizers, specialized pathogen-targeted treatment, and boosting plant pest-resistance, nanotechnology has the potential to change the agricultural industry. Moreover, it can increase plants' ability to absorb nutrients and to endure environmental stresses. The fertility of the soil is a key factor in helping the economy and agriculture in developing nations. The benefits of strategies using nanotechnology for sustainable agriculture are covered here.
