lo CROP PRODUCTION 



Give good tillage and care. Thin the seedlings to two 

 inches apart. 



See that the seedlings develop roots by autumn and 

 that the roots from last year's growth develop flowers 

 and seeds. 



This sort of a plant is called a biennial, because it 

 takes two years to produce seed. 



Beets and Mangels 

 Seed Structure 



Twenty beet seeds for each pupil. 



Place in germinating box or plate. When germina- 

 tion begins examine the seed under a hand lens. Find 

 the exact number of plants starting from one seed. 



Examine many seeds to see if they are really seeds or 

 a sort of seed-pod, each holding two or more seeds. 



Growing in the Garden 



Sow seeds and plant beet roots as directed above for 

 the carrot, to show that the beet also is a biennial. 



The Parsnip 

 Germination Test 



Twenty parsnip seeds for each pupil. 



Place in germinating box or plate with carrot seeds. 

 Examine daily. Record germination and compute 

 percentage. 



Compare time of germination .of parsnip seeds with 

 the time of germination for carrot seeds.
