148 CROP ROTATIONS 



5. Good Local Rotations. Outline one-year rotations, two-year rota- 

 tions, three-year rotations and four-year rotations. Use crops producing 

 yields suited to the market conditions of the region. This exercise should 

 give systems different from those suggested in this chapter. 



6. Succession Cropping. Find examples of succession cropping among 

 gardeners nearby. Give a description of the time of planting and other points 

 of management for each of the crops in succession. 



7. Companion Cropping can easily be found among commercial gardeners 

 and in home gardens. Each example should be described in detail.
