Present invention provides specially device and methodology for the construction and working of Automatic Fertilizer Injector Machine for cotton plants. As the fertilization process in cotton plant is day long and time consuming process as it requires larger man power. The invention simplifies the whole process and saves time as well as labor cost. Invention completely works manually it do not requires fuel and external electric supply, it is eco-friendly. Invention requires only one operator for the process to be done. It takes the required power from the motion of the wheel of the machine. As the operator push the machine wheel rotates and axel on which wheel mounted also rotates and CAM arrangement on the shaft give the required motion to the mechanical hands which perform the operation. The idea is to devise Mechanical Hands which will injects the fertilizer around the roots of crops at pre matured stage .An injector mechanism is placed at each hand which will guide the injection of fertilizer in semicircular pattern around the crop. Following invention is described in detail with the help of Figure 1 of sheet 1 shows the model of a Fertilizer injector machine.
