An analytical approach to quantum mechanical tunneling time in electronic devices
Starting from the analytical solution to the Time-Independent Schrodinger Equation, and exploiting the analogy between the transmission line equations and the time-independent Schrodinger wave equation, an analytical expression for the Average Particle Traversal (APT) time, {dollar}\tau\sb{\rm APT},{dollar} through a rectangular potential barrier region, under no bias, is derived, in terms of the barrier width, potential, and the incident energy of the electron. This approach is extended to derive an analytical expression for the APT time through a resonant tunneling structure, two symmetrical rectangular potential barriers sandwiching a potential well, under no bias. The results of the single potential barrier traversal time are compared with that of other approaches. The APT time is inversely proportional to the transmission coefficient, and satisfies physically intuitive energy limits. For the resonant tunneling structure, the APT time is minimum at resonant energies, and the {dollar}\tau\sb{\rm APT}{dollar} is inversely proportional to the transmission coefficient. The maximum frequency of oscillation is estimated and compared for some of the experimentally studied resonant tunneling structures based on the APT time. The agreement is excellent
Phytomicrobiome-Resilience to climate change
The abnormal change in weather has resulted in rise in global temperature and the frequency as well as intensity of abiotic factors like drought has a negative influence on agricultural production in many areas. These aspects are mainly related to nutrient acquisition and stress tolerance. Changing the phytomicrobiome or its interactions can improve both of these parameters. "Phytomicrobiome" refers to the microbes that are associated with plants, including bacteria, archaebacteria, fungi, and viruses. It is a community of microorganisms that establish essential ecological relationships with the host plant. This community has the potential to protect the plant against abiotic stresses such as drought, heat, and salinity by producing antioxidant enzymes, plant growth hormones, bioactive compounds, and by detoxifying harmful chemicals, Reactive Oxygen Species (ROS), and free radicals. The abiotic factors have significantly impacted the diversity of microbiome in rhizosphere, phyllosphere and endophytes. To cope with adverse condi- tions, phytomicrobiomes enables the plants to develop sophisticated mech- anisms to sense the stress signals to ensure optimal growth responses. The phytomicrobiome has played a crucial role in creating new bioinoculants, Plant Growth Promoting Rhizobacteria (PGPR) formulations, biofertilizers, biostimulants and biocontrol agents being effective alternatives to chemical fertilizers in future for specific crops, contributing to sustainable agricultural productivity for farmers and society. This article mainly emphasizes on the phytomicrobiome interactions for plant health and how environmentally friendly methods can be used to maximize the agricultural productivity as well as how the phytomicrobiome can be used to reduce the effect of drought stress on plants and boost crop productivity
Nutrient recycling through composting: Harnessing agricultural wastes for sustainable crop production
Composting repurposes agricultural waste into organic fertilizer, reducing dependence on chemical alternatives while enhancing soil health. Compost supports long-term fertility by improving the physical, biological, and chemical properties of the soil. Crop residues in fields contribute to humus formation and provide essential nutrients for future crops. Incorporating these residues into the soil stimulates microbial activity, which results in improved soil vitality. Research consistently demonstrates that recycling residues enhances the physical, chemical, and biological health of the soil. Managing crop residues offers sustainable and environmentally friendly solutions for meeting crop nutrient needs and improving yields. Microorganisms play a crucial role in breaking down agricultural waste, into compost that boosts soil fertility and health. This process leads to increased agricultural productivity. It is essential for farmers, particularly in developing countries, to understand the complexities and benefits of composting. The rising global population has intensified the demand for food, leading to increased agricultural production. However, this growth also generates large amounts of waste, posing environmental and health risks. Composting offers more than just a soil amendment; it represents a vital approach to sustainable farming practices. By converting agricultural residues into nutrient-rich compost, farmers can mitigate the environmental impact of waste while improving the health and productivity of their soil. It examines how composting agricultural waste into nutrient-rich organic fertilizer enhances soil health, reduces dependence on chemical inputs, and promotes sustainable farming. It also investigates the role of microorganisms in improving soil fertility and productivity while addressing the environmental impact of agricultural waste
Agrivoltaic farming: A sustainable approach for climate-smart agriculture
Food security in India is increasingly getting threatened by climate change and the growing population. India is working towards achieving net-zero emissions by 2050. Integrating photovoltaics (PV) with agriculture has emerged as a viable option and has given rise to agrivoltaics (AV) which can prove as an innovative solution addressing land competition. Agrivoltaics is a technique that combines solar energy with farming. It offers multiple benefits such as increased agricultural yields, water conservation and reduced greenhouse gas emissions. This paper explores agrivoltaics as a Climate-Smart Agriculture (CSA) approach for Indian farmers and establish a sustainable and reliable model for the future. Agrivoltaics enables dual land use optimizing both food and energy production while mitigating the adverse effects of climate change. It helps improve resource efficiency ensuring a more resilient agricultural system. The potential of agrivoltaics is assessed using Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis. This analysis provides information about its strengths such as land optimization and climate mitigation effects; weaknesses including high initial costs; opportunities, like policy support and technological advancements; and threats, such as land-use conflicts and limited awareness. Implementation of agrivoltaics in Indian agriculture can bring greater sustainability ensuring food security while contributing to clean energy goals. This review emphasizes use of agrivoltaics as a transformative solution for achieving climate resilience and sustainable development in India's agricultural sector

Eco-friendly approaches for controlling Echinochloa colona in rice ecosystems using natural herbicides
Echinochloa colona, a highly invasive weed, poses significant challenges to rice cultivation globally and is usually managed effectively through chemical herbicides. Conventional chemical herbicides have contributed to environmental degradation and increased herbicide resistance. This study explores the potential of natural herbicides derived from plant extracts as eco-friendly alternatives for sustainable weed management. Ten plant samples, including Calotropis gigantea, Ocimum tenuiflorum and Prosopis juliflora, were collected and their allelochemicals were extracted using Soxhlet extractor with methanol and hexane solvents. The efficacy of these extracts in inhibiting E. colona germination was tested through pot culture and laboratory assays. GC-MS analysis identified key allelochemicals responsible for the phytotoxic effects, leading to the formulation of natural herbicides in the form of Emulsifiable Concentrates (EC). Field experiments were conducted to assess the performance of these formulations in rice ecosystems. Results indicated that pre-emergence application of 50% EC formulation of 10% methanolic extract of Ocimum tenuiflorum + one hand weeding at 25 DAS showed significant reduction in weed density, dry weight, weed index and increase in weed control efficiency, crop yield and highest benefit cost ratio though further optimization is required to improve formulation stability. This study demonstrates the potential of natural herbicides as effective and sustainable tools for managing E. colona in rice fields, providing an alternative to synthetic chemicals. The findings underscore the need for continued research into the development of durable and efficient natural herbicide formulation
Diversidad microbiana y perfiles funcionales de tres biofertilizantes comerciales e impactos sobre comunidades bacterianas de la rizósfera del suelo en el aguacate
Chilean avocado (Persea americana Mill.) exports have accounted for 60 % of the total production and are recognized for their high quality worldwide. However, avocado production has significantly decreased in recent years, which is mainly attributed to abiotic and biotic factors, among which are high and low temperatures, intense and sudden rains, unavailability of water resources, and agricultural salinity. Secondary factors include pests and diseases. Applying plant growth promoting microorganisms (PGPM)-based commercial biofertilizers is a potential practice to increase avocado production and resistance to edaphoclimatic factors. In this study, to determine the functionality of microbial communities present in three commercial biofertilizers (Biofert A, Biofert B, and Biofert C) and thus offer a structure of associated microbial communities, the rhizospheric soil of avocado was analysed using the Biolog EcoPlate™ technique, providing information on the community level physiologic profiles (CLPP) and biodiversity indices by denaturing gradient gel electrophoresis (DGGE). The findings revealed that the microbial diversity in the three commercial biofertilizers is highly different, showing a SIMPER overall dissimilarity of 83.9 % in the catabolic capacity. Concerning the impact on avocados’ rhizosphere soil bacterial communities, the results demonstrated significant changes in their composition, particularly with Biofert A and C. In contrast, Biofert B did not show significant changes, especially on days 15 and 30. Long-term studies are recommended to develop sustainable agricultural practices for Chilean avocados.Las exportaciones de aguacate chileno (Persea americana Mill.) representan el 60 % de la producción total y son reconocidas por su alta calidad a nivel mundial.

Management of paddy soaking water: as a source for enriched compost making
The effluents discharged from rice mills do not contain toxic compounds, but continuous discharge in to soil or surrounding water bodies cause adverse environmental effects. Hence, the aim of the research was selected as management of paddy soaking water with its composition of nutrients as source for preparation of enriched compost and also is useful for the control of wastewater pollution and make safe the environment with effective usage. The characteristics of the effluent generated from cold soaking were acidic pH of 4.0 with concentration of nitrogen as 98 mg/l, phosphorous (91mg/l), potassium (98 mg/l), and reducing sugar (76 mg/l) and high concentration of COD (2760 mg/l), total dissolved solid (2800 mg/l) and electrical conductivity of 6mS/cm. Wastewater from the paddy soaking was then used as a potential source to an anaerobic composting. The digester with organic solid waste of 5 kg was mixed with 30 lit of rice mill effluent and other with 30 lit of water as control. The experiment was conducted in complete randomize design with three replicates. The use of rice mill wastewater significantly increased the available nitrogen, phosphorous and potassium after completion of 42nd days. Chemical analysis of digestate revealed that nutrition profile for anaerobic compost making of paddy soak water with waste was better than that of water. The C/N ratio decreases with days of composting but the reduction rate was high in paddy soak water than the water treated. Therefore, the rice mill wastewater is useful for compost making in anaerobic condition with the production of enriched compost
