A Study of The Work of The Flap Plow in Silty Loam Soil (Mould Board Plow)

This study was carried out in one of the agricultural fields affiliated to the University of Basra in the year 2022, where the study included the use of the tractor type (Massey Ferguson MF 375) with the rotary cultivator at different speeds, as well as the use of different depths to study the effect of this on silty clay soils. In this experiment, the effect of two factors was studied. They are the plowing depths (0.13, 0.185, 0.235 m) and the plowing speed of the tractor with the tipper plow, which ranged from (0.977, 1.347, 1.805 m/sec) in the studied technical indicators, which included practical productivity, the real efficiency of the symptoms, soil resistance to penetration, and the percentage of slip. The research was carried out according to the randomized complete block design and with four replications using the practical experiment method, where the statistical results and differences tests were analyzed in a manner with the least significant difference at the level of (0.05). To the decrease in the practical productivity and field efficiency of the plows with an increase in soil resistance to penetration and the percentage of slippage, and the plowing depth exceeded 0.15 meters over the plowing depths (0.235, 0.185) meters in achieving the highest rate of practical productivity with the highest field efficiency of the plow, as well as achieving the lowest soil resistance rate For penetration with the lowest anti-overturning ratio, while increasing the practical speed of the plow from 0.997 to 1.347 m/sec and then to 1.805 m/ sec led to an increase in practical productivity with a decrease in the field efficiency of the plow as well as an increase in soil resistance to penetration with an increase in the slip percentage.
