The results show that precise vineyard management practices, based on a deep understanding of grape biology and environmental conditions, can achieve high yields. This study provides insights into the balance between yield and grape quality, emphasizing the combination of scientific theory with targeted agronomic practices in order to achieve sustainable grape yield. Keywords Grapevine yield; Agronomic practices; Vineyard management; Grape physiology; High productivity 1 Introduction Grapevine (Vitis vinifera) is one of the most economically significant fruit crops globally, cultivated for various purposes including wine production, table grapes, raisins, and grape juice (Zhang et al., 2021; Bharati et al., 2023). Achieving high yield in grapevines is crucial for the profitability and sustainability of viticulture. Yield not only affects the economic returns for grape growers but also influences the quality and quantity of the final products (Zinelabidine et al., 2021; Leão and Oliveira, 2023). Understanding the factors that contribute to grape yield is essential for optimizing production and meeting market demands. Achieving high yield in grapevines is fraught with challenges, including environmental stresses, climate change, and the prevalence of pests and diseases (Keller, 2010; Bharati et al., 2023). Environmental factors such as water availability, temperature, and light conditions play a significant role in yield formation and fruit quality (Kuhn et al., 2013; Guilpart et al., 2014; Zhu et al., 2020). Additionally, the genetic makeup of grapevine cultivars and their interaction with rootstocks can significantly influence yield outcomes (Leão and Oliveira, 2023). However, these challenges also present opportunities for innovation and improvement. Advances in agronomic practices, such as the adaptation of regional agronomic diagnosis and the use of mechanized methods like dry-on-vine (DOV) for raisin production, have shown promise in managing yield variability and enhancing productivity (Fidelibus, 2021; Merot et al., 2022). Furthermore, integrating genomic selection with polyploidization techniques offers potential for developing superior grapevine genotypes with enhanced yield and stress resistance (Bharati et al., 2023). This study examines the factors influencing grape yield, including environmental conditions, genetic factors, and agronomic practices. It identifies the critical periods and conditions that affect grape yield formation and fruit quality, and evaluates the effectiveness of various agronomic interventions and technological advancements in optimizing grape yield. The findings aim to provide a reference for grape growers to achieve sustainable high-yield grape production under evolving environmental conditions and market demands.
