354 CHAPTER XXI 



11. Drilling should be practised instead of broadcasting. 



12. In parts having a summer rainfall, grow sorghums, 

 millets, flint maize for ensilage, potatoes, cotton, covvpeas, 

 soy beans and tepary beans. 



13. In parts having a winter rainfall, grow wheat, emmer, 

 field peas and vetches. 



14. Where the above cannot be grown, grow the fodder 

 trees and shrubs previously mentioned. 



15. Cultivation of the soil increases fertility and thus 

 lessons the transpiration ratio. 



16. It cannot be over-emphasised that in parts of limited 

 and erratic rainfall, farming must be considered from the view- 

 point of the livestock farmer. The returns from animal hus- 

 bandry are not only more certain, but are more profitable than 

 those from field husbandry. The rearing of livestock is of 

 major importance, and cropping must be undertaken to supple- 

 ment the requirements for foodstuffs. Hence a policy should 

 be pursued which aims at the production of forage, fodder and 

 silage, rather than one where grain production is looked upon 

 as the main source of revenue. The crops cultivated should be 

 grown with a view to supplementing the natural pasturage, and 

 by storage provision should be made for drought.
