Scientific Advances in Tomato (Solanum lycopersicum L.) Cultivation, Agronomic Innovation and Genetic Improvement: A Comprehensive Review

Tomato (Solanum lycopersicum L.) is one of the world's most significant vegetable crops, appreciated for its high nutritional content, economic relevance and wide range of industrial applications. It is high in vitamins, minerals, lycopene and antioxidants, all of which help to improve human health and diet security. Tomatoes are the world's largest crop in terms of area and production, with India among the main producers. Climate change, soil degradation, soil types, pests, illnesses, physiological abnormalities and post-harvest losses all have an impact on productivity. Recent developments in scientific farming procedures have shown amazing potential for increasing output, quality and sustainability. Tomato production is being transformed by improved varieties and hybrids that are resistant to major biotic and abiotic challenges, precision farming techniques, drip irrigation and fertigation, integrated nutrition management and protected culture systems including polyhouses and greenhouses. Plant growth regulators, grafting, and mulching all help to promote fruit set and quality. Integrated pest and disease management systems, together with biocontrol agents and resistant varieties, are critical for decreasing pesticide use and guaranteeing environmental safety. Post-harvest technologies such as better harvesting, grading, packaging, cold storage, and processing provide value to the supply chain while reducing waste. Furthermore, molecular breeding, marker-assisted selection and CRISPR-based gene editing are emerging as significant genetic improvement technologies in tomato, with the potential to generate climate-resilient, nutrient-rich cultivars. It also emphasizes sustainable ways and future opportunities to increase production and profitability, assuring tomatoes' continued role as a major crop in global horticulture and nutrition security.
