The Effect of Container Size on Bush Bean Production for Urban Contain Gardens.

In the realm of urban agriculture and container gardens there is little literature discussing the yield potentials for various fruits and vegetables.  A pilot greenhouse study was set up to determine the effect of container size on the yield and growth of bush beans.    Beans were planted in either (n=24) a 4-inch standard greenhouse pot, 2-liter soda bottle, a 500ml water bottle, or a simulated garden with 8-inch soil depth as the control.    The containers were watered at ET=100% by weight and exposed to the same environmental parameters.    The study showed there was no significant effect on germination rates or flowering dates across all containers.   The control had significant differences in height and chlorophyll over the 500ml and 4-inch pot but not the 2 liter soda bottles.    This poster will show results of the pilot study and secondary studies. However, based on the results bush beans should not be used as a container crop in the urban setting.
