The Influence of Seasonal Cropping on The Growth Dynamics, Dry Matter Partitioning, and Yield of Potato Cultivars in The Tropical Regions of Iran

Objectives: The objective of the research is to investigate the effects of high temperatures on the physiological and biochemical characteristics of different potato cultivars (Solanum tuberosum) and to assess their performance in terms of yield parameters, particularly focusing on marketable tuber yield, dry matter accumulation, and tuber bulking rate under varying climatic conditions. The study aims to identify cultivar responses to high-temperature stress and evaluate crop management practices on potato growth and development.

Data description: The study examines the performance of various potato cultivars—Coronada, Colomba, Sylvana, Challenger, Atosa, Sante, Concordia, Ottawa, Georgina, and Ribera—across autumn and winter cropping seasons in the Jiroft region of southeastern Iran. Key yield parameters, including marketable tuber yield, dry matter accumulation, and tuber allocation, were measured post-harvest, while growth parameters such as tuber bulking rate, tuber growth rate, and crop growth rate were evaluated during the growing seasons. Utilizing a split-plot design with three replicates, the research involved 60 experimental plots. Data analysis was performed using ANOVA to determine the significance of main effects and interactions. Soil samples were analyzed for nutrient status and PH before planting
