Kiwifruit, a globally important crop, presents a unique opportunity to evaluate the impact of organic fertilization on both productivity and quality. This study examines various organic fertilizers used in kiwifruit cultivation, their application methods, and the influence on soil health and nutrient composition. Our analysis focuses on yield performance under organic fertilization, long-term effects on soil fertility, and a comparison with conventional practices. Additionally, the study explores how organic fertilization affects kiwifruit quality, including fruit size, nutritional content, taste, and post-harvest shelf life. Environmental benefits, such as reduced chemical inputs and enhanced sustainability, are highlighted alongside the economic advantages of organic kiwifruit in the market. Challenges, such as lower initial yields and regulatory issues, are discussed, with a case study demonstrating real-world applications. The study concludes by identifying research gaps and emphasizing the need for long-term studies and innovations in organic fertilizer development. Future directions focus on integrating organic practices with precision agriculture for improved productivity and sustainability. Keywords Organic fertilization; Kiwifruit productivity; Soil fertility; Sustainable agriculture; Organic fruit quality 1 Introduction Organic fertilization has gained significant attention in horticulture due to its potential to enhance soil health, improve crop yields, and reduce environmental impacts compared to conventional chemical fertilizers (Fan et al., 2023). Organic fertilizers, derived from plant and animal residues, contribute to the sustainability of agricultural systems by improving soil structure, increasing microbial activity, and enhancing nutrient availability (Liu et al., 2020). The application of organic manures, such as dairy manure, vermicompost, and chicken manure, has been shown to positively affect plant growth, nutrient uptake, and soil properties, making it a viable alternative to chemical fertilizers (Lago et al., 2019; Ma et al., 2021). Kiwifruit (Actinidia spp.) is a valuable horticultural crop known for its high nutritional value, including vitamins, minerals, and antioxidants (Sanz et al., 2020). It is widely cultivated in various regions, including China, Italy, New Zealand, and Chile, contributing significantly to the global fruit market. The demand for high-quality kiwifruit has driven research into optimizing cultivation practices to enhance fruit yield and quality. Organic fertilization has emerged as a promising approach to meet these goals while maintaining environmental sustainability (Zhao et al., 2017; Lu et al., 2018). This study aims to evaluate the impact of organic fertilization on kiwifruit productivity and quality. The study will explore various organic fertilization regimes, including the use of different organic manures and their combinations, and their effects on soil properties, microbial diversity, plant growth, and fruit quality. By synthesizing findings from multiple research studies, this study seeks to provide insights into the benefits and challenges of organic fertilization in kiwifruit cultivation, offering recommendations for best practices to enhance sustainable kiwifruit production.
