In the present invention, support bodies constituting a crop support are formed to be easily assembled and disassembled, so that the length of the support can be flexibly adjusted according to the length of a crop. Accordingly, the length of the support is fixated and thus, a conventional problem in which an immediate response to the length of a crop is difficult can be solved. A front end body can be assembled and dissembled, so that an end portion of the front end body hit by a hammer is formed at a low position and therefore can be installed by one worker to thereby improve work efficiency significantly. Furthermore, the front end portion of the front end body has the shape of a sharp spear and is easily inserted into the ground, so that installation can be more easily performed. The worker can easily install a plurality of crop supports in a desired form (vertical, inclination of 45 degrees, square tunnel, round tunnel, etc.) by using a connection body having the inverted &primeV&prime or &primeU&prime shape. Moreover, since connection grooves are formed on an outer circumferential surface of the support body at certain intervals in a lengthwise direction, and thus a string tied between the adjacent crop supports is prevent from being slid down, thereby improving cultivation efficiency. The crop support of the present invention comprises: a front end body having a front end inserted in the ground, a first coupling unit, a front end body main body equipped with a pin insertion groove, and a front end having a shaft-shaped pin coupling unit formed therein to be coupled with the pin insertion groove of the front end body main body and a support body having a second coupling unit formed in the front end thereof to be coupled with the first coupling unit of the front end body and having a third coupling unit formed in the rear end thereof.COPYRIGHT KIPO 2015본 발명은 지지대를 형성하는 지지몸체들의 조립 및 분해가 용이하게 이루어짐으로써 작물의 길이에 대응하여 지지대의 길이를 유동적으로 조절할 수 있고, 이에 따라 길이가 고정되어 작물의 길이에 즉각적으로
