Performance Mechanized Set Tractor-Planter of Sugarcane Planting in Two Operation Shifts

Abstract

The studies on the operational performance of sugarcane machinery, in particular the mechanized planting system, are still incipient in Brazil, requiring greater efforts to increase the quality of agricultural operation. In this context, this study aimed to evaluate the operational performance of sugarcane mechanized planting in two operation shifts. The mechanized planting was conducted in the municipality area of Monte Alto -São Paulo (SP), Brazil. The statistical design was completely randomized, totaling 80 sampling points, from which 40 points for daytime operation and 40 points for nighttime operation. The variables evaluated were: displacement speed, engine rpm, engine oil pressure, engine water temperature, effective field capacity, and hourly and effective fuel consumption. The coefficient of variation is greater for the alignment of the tractor at night shift, while the coefficients of skewness and kurtosis are higher during day shift. Displacement speed, engine rpm, engine oil pressure, hourly and effective fuel consumption, and effective field capacity showed no influence over the shift operation.

Application of Statistical Process Control in Mechanized Corn Seeding

“…The use of process quality control instruments is necessary to ensure the correct functioning of the process based on critical factors and, specifically in agriculture, aims to identify factors related to the efficiency and effectiveness of agricultural operations (MELO et al, 2013). Therefore, with the application of this instrument, it is possible to verify the stability of agricultural operations, indicating whether the instability or variability of the agricultural process is generated by random causes (intrinsic) or by special causes (extrinsic), which helps in decision-making (VOLTARELLI et al, 2015).…”
