International Journal of Horticulture, 2025, Vol.15, No.3, 113-122 http://hortherbpublisher.com/index.php/ijh 120 environments, such as the eastern sub-Himalayan plains, has shown that cultivars like Kufri Arun and Kufri Pukhraj can achieve high yields and economic returns, making them suitable for specific regions. The quality of seed tubers also plays a pivotal role in achieving high yields, as demonstrated by the differential growth responses of local cultivars. The integration of optimal irrigation and fertilization practices can further enhance yield and quality, as seen in studies conducted in Serbia. 8.2 Practical significance and application prospects of research findings The findings from these studies have significant practical implications for potato cultivation. The identification of high-yielding and stable cultivars provides farmers with reliable options to maximize their production and profitability. For instance, the cultivar Kufri Arun has shown the highest net return and benefit-cost ratio, making it a highly recommended choice for farmers in the eastern sub-Himalayan plains. The research also highlights the importance of tailored cultivation techniques, such as the optimal sowing time, fertilization formula, and pest control measures, which can significantly improve both yield and quality. The adoption of advanced irrigation methods and appropriate fertilization strategies can enhance tuber quality, which is essential for processing industries. These insights can guide agricultural practices and policies to support sustainable potato production. 8.3 Expectations for the future development of the potato industry Looking ahead, the potato industry is poised for significant advancements driven by ongoing research and innovation. The development of drought-tolerant cultivars is particularly crucial in the face of climate change, as it can mitigate yield losses and ensure stable production. The exploration of new cultivation techniques, such as ridge cultivation and optimal plant densities, can further enhance yield and nutritional quality, as demonstrated in studies on sweet potatoes. The potential for yield improvements remains substantial, with actual yields still falling short of the theoretical potential in many regions. By bridging this yield gap through improved agronomic practices and cultivar selection, the potato industry can achieve higher productivity and resilience. The continued focus on breeding high-yielding, climate-resilient cultivars and refining cultivation techniques will be essential for meeting the growing global demand for potatoes and ensuring food security.
