SEEDS— WEEDS. 



Test of beet seed, B. Walker {South Carolina Sta. Bui. 34, pp. 

 7-9). — A report is given of investigations made to test the relative 

 value of large and small beet seed. Of the various lots of seed as pur- 

 chased about 40 per cent were large and plump, while CO per cent were 

 small, poorly developed, and more or less imperfect. The seed which 

 were grown in shallow boxes were pressed uniformly into the soil and 

 then covered with fine sand. One lot of the seeds was soaked for 5 hours 

 in warm water, while the other was planted dry. The germination of 

 the different lots of large and small beet seed is shown in the following 



table : 



Germination of large and small beet seed. 



In conclusion the author states that large seed is to be much preferred, 

 since it gives a larger percentage of germination as well as stronger
