Sericulture generates large volumes of valuable by-products, particularly silkworm pupae, litter, reeling effluents and plant waste, collectively termed seri-waste. These by-products possess immense nutritional, medicinal and industrial potential, making sericulture a sustainable, zero-waste enterprise. Silkworm pupae are rich in high-quality proteins, essential amino acids, vitamins, minerals and bioactive compounds with antioxidant, antimicrobial, anticancer and metabolic health benefits. Their oils contain beneficial unsaturated fatty acids, while larvae and excreta support biogas production, organic farming and compost enrichment. With the rising global demand for eco-friendly food and agricultural resources, the efficient utilisation of seri-waste offers a promising avenue for enhancing food security, environmental sustainability and rural livelihoods.

Chrysanthemum, a time-honoured flower, is admired not only for its vibrant beauty as an ornamental plant but also for its therapeutic, edible and industrial applications, particularly in East Asian traditional medicine. Its delicate blooms are rich in health-promoting compounds, extending its relevance from ancient remedies to modern wellness products. In Eastern cultures, the chrysanthemum is also a cherished symbol of wealth, good fortune, longevity, and happiness.

The integration of mechanical innovation and digital sensor systems has transformed agricultural productivity and operational efficiency. This review synthesizes contemporary research focusing on three major domains: performance optimization of agricultural machinery, development of digital tachometers for RPM measurement, and comparative evaluations of sensor technologies. Studies indicate significant improvements in fuel economy, reduced crop damage, and accurate, non-contact RPM detection through sensormicrocontroller integration. The review highlights future directions such as IoT-based sensor networks and enhanced digital monitoring for sustainable agricultural mechanization.

Amidst the rapid growth of technology, digital marketing has become a revolutionary tool for improving the marketing efficiency of India's agriculture sector. Traditional marketing which has limited reach and multiple intermediaries, restrict price realization and market access by farmers. The use of smartphones and increased internet access has sped up the adoption of digital platforms, allowing for more direct, transparent, and extensive market connections. By decreasing information asymmetry and increasing efficiency, government programs like e-NAM and Agmarknet, as well as commercial platforms like Marketmirchi and Ninjacart, are changing agricultural trading. Digital marketing has the ability to significantly improve agricultural value chains and empower farmers through improved price discovery, lower transaction costs, and increased market options, despite obstacles including poor digital literacy and inadequate infrastructure.

Agricultural stubble burning in rice-wheat growing regions generates 7,300 kg CO? emissions per hectare while severely degrading air quality and soil health. This article examines wheat and rice straw utilization for oyster mushroom (Pleurotus species) cultivation as a sustainable alternative. Evidence demonstrates biological efficiencies of 60-85% when substrates are supplemented with nitrogen-rich materials, generating gross revenues of 120,000-250,000 Indian Rupees per 100 m? annually for smallholder farmers. Spent mushroom substrate application enhances soil health through nutrient recycling and organic matter addition. This integrated approach simultaneously addresses environmental degradation, food security, farmer income, and climate change mitigation across major cereal-producing regions.
