Performance Evaluation of Self-Propelled Rice Transplanter for Impact Study on Rice Cultivation

Description

Rice stands as the cornerstone of global food security, feeding more than half of the world’s population. Traditionally, rice cultivation has relied on two primary methods: direct seeding and manual transplanting. While direct seeding is less labor-intensive, manual transplanting—though yielding better crop stands—is physically exhausting and increasingly unsustainable due to rising labor costs and a dwindling rural workforce.

The transition toward mechanical transplanting represents a significant technological leap. This study, conducted at the Yamagata University Faculty of Agriculture, Takasaka Farm, provides a rigorous technical evaluation of the Kubota NSU-87, an eight-row self-propelled paddy transplanter. Using the ‘Heanuki’ rice variety, the investigation analyzed mechanical efficiency, fieldwork accuracy, and ultimate agronomic yield to determine the viability of this technology for modern intensive farming.

The primary metric for evaluating any agricultural machine is its efficiency in the field. This is determined by the relationship between Theoretical Field Capacity (TFC) and Effective Field Capacity (EFC).
