how to draw a labelled diagram of mixed cropping of beans , corn and pumpkin

Mixed cropping is a technique in which two or more types of crops are allowed to grow on a same field at a same time. For example:- Sugarcane, Alfalfa and sudangrass are produced by this method.  This method is very helpful for the farmers as they get good yield and economy. This method also increase the fertility of the soil. In this type of method one crop can help other crop in its growth, like if a farmer is growing legumes with other crop together, the other crop will take nitrogen from the soil whereas legumes will fix the nitrogen again in the soil for further use.
