Abstract
This experiment was conducted in an agricultural field in Hindiah district in the Secret province of Karbala, in a silt loam soil during the year 2019, to study the effect of tow types of plows the sweep and chisel plow (factor1) and tow types of pulverization equipment Rotavator and spring pulverization (factor1) on Beans growth and some technical indicators for machinery unit. The effect of these tow factors and the interactions between them on Slippage percentage, practical productivity, Fuel consumption, power requirement, percentage of knot and plant production were studied. Massy Fergusson tractor of (MF650) was adopted in the experiment, and Two parameters were used, the first one is: adopting two type of plows (the sweep and chisel plow) which represented the main plots (the Rotavator and spring pulverization), which represented the secondary plots. the experiment was conducted by the split plots according to the Complete Randomized Block Design, in three replicates. The results showed (according to the experiment conditions): that the sweep plow had have the advantage in recording the least percentage of slippage of (11.64%), least fuel consumption of (13.44%), the highest average of power requirements per area unit of (kwat. hr.h−1), highest percentage of knots ratio of (13.44%) and the highest plant production of (6054kg.hr−1). whereas the Chisel plow have had the advantage in recording the highest practical productivity of (1.29 hr.h−1). the rotavater have had the advantage in recording the highest practical productivity of (1.35 hr.h−1), highest knot ratio of (13.41%) and the highest plant production of (5932.5 kg.hr−1).whereas the spring harrow recorded the least slippage percentage of (9.94%), least fuel consumption of ( 17.13 Li.hr−1) and the least requirements of power ratio per area unit of ( 66.57 kwat.h.hr−1). as for the dual interactions, it did impacted significantly in all the studied traits.
