The present invention relates to an agricultural water pipe branch part which is installed in a main water pipe to connect the main water pipe and a branching pipe and a branch hose to allow a water current to separately branch in various directions where a crop is located from the main water pipe installed in a crop field (a greenhouse or a field) and, more specifically, to a agricultural water pipe branch part which improves a structure of a saddle for agricultural water pipe branching to conveniently assemble the saddle and tightly attach the saddle to the ground during installation to provide excellent watertightness and improve a work environment. More specifically, a branch body having a branch part and a support part are divided to couple lower portions by a hinge to allow the branch part body and the support part to be folded. Halved screws of a halved shape are formed on upper portions of the branch part body and the support part in a tapered shape. When the halved screws of the branch part body and the support part face each other and are tightly attached to each other, a tapered screw of a cylindrical shape is formed. A tightening part having a taper arm screw is screwed and coupled to an inner side of the tapered screw to allow inner surfaces of the branch part body and the support part to have a pipe shape to form a water pipe fixing unit to loosen a tightening unit and unfold a folding unit to insert the main water pipe and lock the tightening unit to couple the main water pipe. Therefore, installation work is simple and the branch part body and the support part are integrated and assembled by a hinge to eliminate a risk of loss during installation work. Specifically, a lower surface of the saddle installed in the main water pipe does not protrude to prevent birdcaging of the pipe where the main water pipe with the saddle assembled thereon rises from the ground to provide an excellent work environment.COPYRIGHT KIPO 2017본 발명은 농작물의 재배지(하우스나 밭 등)에 설치되는 메
