Study of the effect developed chisel plow on some energy requirements and some soil properties in a clayey mixture soil

Abstract

The experiment was conducted at the fields of the College of Agriculture - University of Basra to study the effect height of sweeps shank equipped with the developed chisel plow (10 and 20 cm), with three depths (15, 25 and 35 cm) and three lateral distance (20, 25 and 30 m), on the field performance indicators of the draft force and the area of loosened soil. In a mixed alluvial soil with a density of (1.25) g-cm3 and a moisture content of (15.17) %, the experiment was designed according to the randomized complete block design (RCBD).
 The drafting force increased when the lateral distance and plowing depths increased, while it decreased when the arms of the sweeps shank increased by 20 cm. The loosened area increased when the plowing depths and the lateral distance increased when the arms of the duck hind legs were 10 cm high. The highest drafting force recorded at the height of the arms of the sweeps shank20 cm, the distance between them 30 cm, and the plowing depth 35 cm. The highest loosened area recorded at the height of the arms of the sweeps shank10 cm and the depth of plowing 35 cm.
