Use of nanofertilizers on fruit trees contributes effectively to improve the fruit quality and increasing the productivity of trees. It reduces environmental pollution by reducing the amount of fertilizers used, which is positively reflected in the increased economic return of the farmers. When nanofertilizers sprayed at very low concentration on fruit trees, these compounds have had a direct effect by increasing the growth, yield and quality of these fruit crops.
Indian agriculture feels the pain of fatigue of green revolution.
In the past 50 years, the fertilizer consumption exponentially increased from 0.5 (1960’s) to 24 million tonnes (2013) that commensurate with four-fold increase in food grain output (254 million tonnes) In order to achieve a target of 300 million tonnes of food grains and to feed the burgeoning population of 1.4 billion in 2025, the country will require 45 million tonnes of nutrients as against a current consumption level of 23 million tonnes. The sustainable agriculture and precision farming both are the urgent issues and hence the suitable agro-technological interventions are essential (e.g., nano and biotechnology) for ensuring the safety and sustainability of relevant production system.
Here, it is a brief presentation regarding nanofertilizer, in relation to its role in enhancing the use efficiency of concerned nutrient, along with some experimrntal findings. Thank you for ur kind consideration.
The nanotechnology aided applications have the potential to change agricultural production by allowing better management and conservation of inputs of plant and animal production. Several nanotechnology applications for agricultural production for developing countries within next 10 years has been predicted (Salamanca–Buentella et al., 2005).
Nanoparticles helps in Controlling the Plant Diseases, application of agricultural fertilizers, pesticides, antibiotics, and nutrients is typically by spray or drench application to soil or plants, or through feed or injection systems to animals. In this context, nanotechnologies offer a great opportunity to develop new products against pests (Caraglia et al., 2011). Nanoscale devices are envisioned that would have the capability to detect and treat an infection, nutrient deficiency, or other health problem, long before symptoms were evident at the macro-scale. The overall goal of this Nanoparticles is to reduce the number of unnecessary problems in agriculture (Thomas et al., 2011). In the management aspects, efforts are made to increase the efficiency of applied fertilizer with the help of nano clays and zeolites and restoration of soil fertility by releasing fixed nutrients (Dongling Qiao, et al., 2016). Nanoherbicides are being developed to address the problems in perennial weed management and exhausting weed seed bank. Bioanalytical Nanosensors are utilized to detect and quantify minute amounts of contaminants like viruses bacteria, toxins bio-hazardous substances etc. in agriculture and food systems (Tothill EI, 2011).
In this way, nanotechnology can be used as an innovative tool for delivering agrochemicals safely. More research should be done on the potential adverse effects of nanomaterials on human health, crops and the environmental safety. It is a challenge to Government and private sector as they have to ensure the acceptance of Nano foods. For it to flourish, continuous funding and understanding on the part of policy makers and science administrators, along with reasonable expectations, would be crucial for this promising field.

Nutrient use efficiency (NUE) is a critically important concept in the evaluation of crop production systems. Many agricultural soils of the world are deficient in one or more of the essential nutrients to support healthy and productive plant growth. Efficiency can be defined in many ways and easily increased food production could be achieved by expanding the land area under crops and by increasing yields per unit area through intensive farming. Environmental nutrient use efficiency can be quite different than agronomic or economic efficiency and maximizing efficiency may not always be effective. Worldwide, elemental deficiencies for essential macro and micro nutrients and toxicities by Al, Mn, Fe, S, B, Cu, Mo, Cr, Cl, Na, and Si have been reported.

Nanotechnology and its use in agriculture.pptxshivalika6
Agriculture is the backbone of most developing countries, with more than 60% of the population reliant on it for their livelihood. Agricultural scientists are facing a wide spectrum of challenges such as: stagnation in crop yields, low nutrient use efficiency, declining soil organic matter, multi-nutrient deficiencies, climate change, shrinking arable land and water availability, shortage of labour besides exodus of people from farming.
Traditional farming techniques have attained saturation and are neither able to increase productivity nor able to restore ecosystems damaged by existing technologies. The global requirement of food is increasing gradually.
In spite of immense constraints faced, we need to attain a sustainable growth in agriculture to meet the food security challenges. To address these problems, there is a need to explore one of the frontier technologies such as ‘Nanotechnology’ to precisely detect and deliver the correct quantity of nutrients and pesticides that promote productivity while ensuring environmental safety and higher use efficiency.
Nanotechnology is one of the most rapidly advancing sciences and possess potential to revolutionize many disciplines of science, technology, medicine and agriculture. Conversion of macromaterials in to nano size particles (1-100 nm) gives birth to new characteristics and the material behaves differently. Nanoparticles can be produced by different methods, chemical and biological, the former is commercially used. Nanomaterials can be potentially used in the crop protection, especially in the plant disease management. Nanoparticles may act upon pathogens in a way similar to chemical pesticides or the nanomaterials can be used as carrier of active ingredients of pesticides, host defence inducing chemicals, etc. to the target pathogens. Because of ultra-small size, nanoparticles may hit/target virus particles and may open a new field of virus control in plants.
This is a seminar paper about nano-fertilizer for agricultural application prepared by Md. Parvez Kabir, an MS Student under the department of Soil Science of Bangabandhu Sheikh Mujibur Rahman Agricultural University.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.

leaves.
• Higher transport and delivery of nutrients through
plasmodesmata which are nanosized (50–60 nm) channels
for transportation of ions between cells.
11
14. Methods of Application of
Nanofertilizers
• Nanofertilizers can be applied through various modes of
applications:
1) Soil application
2) Injection to the plant and
3) in vitro application
4) Foliar application
• The foliar application of nutrients has been proved as a
quick way to rectify nutrient deficiencies and ameliorate
crop productivity
12
15. Benefits of Nanofertilizers
• Efficiently regulate the delivery of nutrients to plants and
targeted sites, guaranteeing the minimal usage of
agrochemicals.
• Increase crop yield by increasing fertilizer nutrient
availability in soil and nutrient uptake by plants.
• Reduce the negative environmental impact of conventional
agricultural practices.
• Improve the leaf area, fruit size and yield.
• Improve the quality and shelf life of fruits.
• Improve the abiotic stress tolerance: salinity and drought.
• Efficient use of nutrients and water: less leaching loss.

18. WHY WE WANT TO USE NANO-FERTILIZERS ?
1) Three-times increase in Nutrient Use Efficiency (NUE)
2) 80-100 times less requirement to chemical fertilizers
3) 10 times more stress tolerant by the crop
4) 30% more nutrient mobilization by the plants
5) 17-54 % improvement in the crop yield.
6) Nano-fertilizers are more beneficial as compared to
chemical fertilizers
16
19. Regulation and Translocation of
Nanoparticles
• It varies from plant to plant, species to species, climatic
factors, age of plant species, biological activity of the plant
and the method of application of nanoparticles.
• The nanoparticles penetrate into the cell wall and cell
membrane of root epidermis accompanied by a complex
series of events to enter plant vascular bundle (xylem).
• Xylem serves as the key carrier in the regulation and
translocation of nanoparticles.
• After entry of nanoparticles into the cell, it can move via
apoplastic or symplastic pathways.
17
20. Limitations of Nanofertilizers
• Nanomaterial phytotoxicity is also an issue in this regard
since different plants respond differently to various
nanomaterials in a dose-dependent manner.
• Reactivity and variability of these materials are also a
concern. This raises safety concerns for farm workers who
may become exposed to xenobiotic during their application.
• Among the various issues, the most important might be the
accumulation of nanoparticles in plants and their food parts.

74. Conclusion
• From above discussion it is concluded that use of
nanofertilizers on fruit trees contributes effectively to
improve the fruit quality and increasing the productivity of
trees.
• It reduces environmental pollution by reducing the amount
of fertilizers used, which is positively reflected in the
increased economic return of the farmers.
• When nanofertilizers sprayed at very low concentration on
fruit trees, these compounds have had a direct effect by
increasing the growth, yield and quality of these fruit crops.
