Design and parametric optimization of a deep-loosening culti vator working body for cotton inter-row tillage

Efficient soil tillage is essential for sustainable cotton production and resource-saving agriculture. Conventional inter-row cultivation requires multiple passes, leading to increased fuel consumption, soil compaction, and operational costs. This study presents the design, analytical modeling, and experimental optimization of a deep-loosening working body integrated into an inter-row cultivator for cotton cultivation. The proposed tool improves soil aeration, water infiltration, and root development while reducing energy consumption. Mathematical models were developed to determine optimal tool geometry considering soil mechanical properties, plant root protection zones, and operational parameters. Experimental investigations evaluated the effects of working width, penetration angle, and tool length on soil fragmentation, loosened layer width, and draft resistance. Regression models were established to determine optimal parameter combinations ensuring maximum agro-technical performance with minimal energy consumption. Field tests confirmed reliable operation and compliance with agronomic requirements. The developed cultivator reduced labor costs by ۵۱% and operational expenses by ۳۲%, while improving soil structure and moisture retention. The proposed design contributes to sustainable and energy-efficient cotton production systems.
