Optimization of operational parameters for pneumatic planting of cotton seeds using a standard metering plate.

ABSTRACT: Cotton, an economically significant crop, incurs high input costs for Bt cotton seeds. Commonly used varieties like RCH 2, Ajeet 155, Ankur 3028, and Suraj exhibit variations in seed size and mass, influencing the design of seed metering plates in pneumatic planters. Typically, each variety requires a specific metering plate optimized for orifice size, vacuum pressure, and operation speed, increasing costs, time loss, and labor dependency. This study aims to design a single seed metering plate accommodating all varieties, optimizing easily adjustable parameters such as vacuum pressure and operational speed. Employing a central composite rotatable design (CCRD), experiments varied orifice diameter (2.5-3.5 mm), vacuum pressure (2.5-5.5 kPa), and speed (2.5-5.5 km/h). Variety-specific optima
