MACHINE INNOVATION FOR INTER ROW COTTON CULTIVATION IN UZBEKISTAN

Uzbekistan is a leading country in cotton production and export. Inter-row cultivation is an important productionoperation that assists in soil loosening, weeding, fertilizing, and ridge forming between rows. However, the operation isproblematic because of risks of damaging the plants during critical growth phases. The article examines a new design forprecision cultivator guidance for inter-row tillage and presents the results of field trials of the new design. The proposedcultivator utilizes light torsion pivots with gauging beams and guiding slits to allow a reduction of the protected zonesurrounding the plant by 2 to 2.5 cm and improves the soil surface condition (soil crumbling ability). Herbicide use and handlabor can be significantly reduced, which should lead to an increase in profit. This cultivator also allowed for an increasein operating speed by 14%, which would increase the efficiency of the operation.
