why does the crop productivity decrease when the same crop is planted continually?
Asked by | 29 Jul, 2010, 12:00: AM
answered-by-expert Expert Answer
Growing the same crop continuously in a field for many years would result in many problems such as deficiency of the same types of nutrients and build up of diseases and insect pests. This leads to decrease in crop productivity.
