The Effect Of The Penetration Angle Of Two Types Of Shanks And Shares Subsoiler Plow On Some Field Performance Indicators

Abstract

This study was conducted with the aim of evaluating the field performance of the locally manufactured shank and share Subsoiler plow and comparing them with the conventional shank and share through a field experiment in which the following factors depended: the type of shank by two levels (the conventional shank , the locally manufactured shank ) and the share type by two levels (the traditional share , the locally manufactured share) and with two angle penetration (40º, 50º) and the effect of this on (Drawbar Power, fuel consumption, Slippage percentage, Distribution Area), Where the experiment was conducted in the autumn agricultural season (2020) in an agricultural field located in the Abbasiya area in Nineveh province. The field was divided according to the randomized complete block design (RCBD) for a factorial experiment with three replicates. Duncan's multiple range test was used to compare the averages. The following are the most important findings studying, , the locally manufactured shank achieved the highest significant value for the distribution area, while the conventional shank achieved the lowest significant value for fuel consumption .While the locally manufactured share achieved the highest significant value for the distribution area, the angle penetration 40º achieved the lowest significant value for fuel consumption, Slippage percentage, and the highest significant value for the distribution area. The interaction between the conventional shank with the traditional share and the angle penetration 40º achieved the lowest significant value for fuel consumption, while the locally manufactured shank and share with the penetration angle 40º achieved the highest significant value for the distribution area.
