LEGUMINOUS CROPS 



Besides for eating out of hand, the peanuts are used for a num- 

 ber of purposes. They are ground and made into peanut butter 

 by the addition of peanut oil or other vegetable oils. In some 

 cases the oil is extracted and is used for a number of purposes. 

 The by-product from the manufacture of oil is ground into pea- 

 nut-oil-meal and is used for feed for stock. 



Other less important leguminous crops grown in limited areas 

 are: Lupines, Florida beggar-weed, serrodella, sainfoin, bird's- 

 foot trefoil, Egyptian clover, horse bean, lotus and kidney vetch.

FIELD AND LABORATORY EXERCISES 



1. Clover Roots. Dig samples of growing clover plants, getting as much 

 of the root system in each case as possible. Compare the root systems of the 

 different kinds of clover. Also compare the differences in the tap-rooted clovers 

 as they appear in different types of soil. Does a hard subsoil make the roots 

 branch more?
