Does the Soil Tillage Affect the Quality of the Peanut Picker?

Machine harvesting is an essential step of crop production, considering a dynamic operation, and subject to losses due several factors that affect its quality. The objective this study was evaluate the quality mechanized peanut pickers in three soil tillage operations using Statistical Quality Control (SQC) tools. We conducted experiments field located at 21°20′23″ S 47°54′06″ W Brazilian farmers. used Statistic experimental design monitor during machine harvesting. treatments evaluated were operations: conventional (CT), rotary tillers (RT), hoe (RH). indicators collected inside picker’s bulk tank. analyses descriptive statistics SQC tools (run charts, control Ishikawa diagram). process considered stable for indicators: whole pods (CT, RT, RH), broken hatched while other showed points out control. With application tools, it possible identify caused increase variability harvesting, listing be improved support decision-making, always aiming operation’s
