Research on the Chlorophyll Content of Vicia faba L. Leaves in Different Farming Conditions

Taking Vicia faba L. as researching materials, the Chlorophyll Content of Vicia faba L. Leaves was investigated under the two different farming conditions of tillage and non-tillage. The results showed that the chlorophyll content under tillage farming was higher than under non-tillage farming. During the flowering, the early and middle fruiting period, the changing curves of the leaf chlorophyll content all take the shape of the double peak regardless of what farming mehtods is actually applied, yet the peak value appears at quite different times.
