Protected cultivation of horticultural crops has emerged as an essential component of modern agricultural systems, offering substantial advantages in terms of improved crop quality, enhanced productivity, efficient resource utilisation, and protection against pests, diseases, and unfavourable environmental conditions. In recent decades, the adoption of protected cultivation technologies has increased considerably owing to the growing demand for high-quality horticultural produce, coupled with the challenges posed by climate variability, diminishing arable land, and increasing population pressure. This comprehensive review seeks to examine the current status of protected cultivation practices in horticulture and to evaluate their future prospects within sustainable agricultural production systems. The review has been conducted using secondary data obtained from existing scholarly literature, including peer-reviewed journal articles, academic books, technical reports, and conference proceedings. Relevant literature was critically analysed to synthesise contemporary developments, technological advancements, and emerging trends associated with protected horticultural production systems. The discussion initially provides an overview of the principal types of protected cultivation structures, including greenhouses, shade houses, polyhouses, low tunnels, and high tunnels, together with their respective advantages, limitations, and suitability for different agro-climatic conditions. Particular emphasis is placed on the role of environmental modification in optimising plant growth and improving crop performance. In addition, the review examines the contribution of protected cultivation towards enhancing water-use efficiency, minimising production risks, and facilitating precision crop management practices. Furthermore, the study highlights the increasingly important role of protected cultivation in addressing global food security concerns through the promotion of year-round crop production, stabilisation of yield, and reduction in dependence on seasonal climatic variability. The integration of advanced technologies, such as automated climate control systems, fertigation, and precision monitoring tools, is also discussed as a promising avenue for improving the economic and environmental sustainability of protected horticulture. Collectively, these developments indicate that protected cultivation is likely to play a pivotal role in the future of high-value horticultural crop production and sustainable agricultural intensification. It also examines the impact of protected cultivation techniques on crop growth and development, particularly in terms of improved morphogenesis, efficient precipitation management, and optimisation of key environmental parameters such as temperature, humidity, and carbon dioxide levels. In addition, the review explores the integration of advanced technologies—such as hydroponics, aeroponics, and vertical farming—within protected cultivation systems, emphasising their potential to maximise productivity while minimising resource use. The challenges and constraints associated with the adoption of protected cultivation, including high initial investment, energy requirements, and dependence on external inputs, are also discussed. Moreover, the paper considers sustainable and eco-friendly strategies to mitigate these challenges, including the use of renewable energy sources and the adoption of organic farming practices to maintain ecological balance. Eventually, the review outlines emerging trends in protected cultivation, focusing on the operation of artificial intelligence, perfection husbandry, and smart husbandry technologies. These innovations are expected to further enhance resource efficiency, automation, and crop monitoring, ultimately leading to improved yield and quality in horticultural production.
