Growing corns and beans

For school general funding, we, the teachers and students, here grow corn and bean every year. Before growing corn, we have to clean the bushes. It takes about 4 months from the time we start growing corn until we can harvest them. To grow corn, we have to rent the land from a Thai boss every year. With farm produces, we can cover some of school basic needs. About 2 or three weeks before we can harvest corn, we start growing bean by spreading bean seeds between the corn plants. It takes about 3 about as well for the bean to be able to harvest it. By doing agriculture, our students can learn not only in-school education but also get knowledge and experience on agriculture. At their age, we do believe that they can learn different fields at the same period of time.
