rectly from the field, and later as a cooked product. Among the 16 varieties 

 and strains judged, Morse Bunching, Imperator, Chantenay Long Type, and 

 Strong-topped Nantes were rated at the top. As a cooked product, Impera- 

 tor, Chantenay, Long-type, and Supreme Half-long rated best. Hutchinson, 

 while low in quality in both instances, produced large handsome roots which 

 made it a strong contender for marketability when quality was not con- 

 sidered a first requisite.

Cultural Practices 



The use of cleaning fluid for spraying carrots was found to be satisfac- 

 tory. Sprayed crops were raised without any cultivation. Among the vari- 

 ous weed sprays tested in asparagus, Sinox gave the most promising results. 



It has been found that in sunshine the temperature inside bean pods, 

 cucumbers and tomatoes may be as much as 20° F warmer than in the ad- 

 joining air. Lettuce tends to remain below air temperature. Artificial in- 

 frared light produces similar results.

STATE SERVICE 



Inspection of Fertilizers and Feeclingstuffs 

 And Soil Testing 



In accordance with the public statutes regulating the sale of commercial 

 fertilizers and of concentrated commercial feedingstuffs, 63 brands of fer- 

 tilizers and 591 brands of feedingstuffs were analyzed during the year 1946- 

 47. These analyses involved individual determinations totaling 436 and 3030 

 respectively. Co-operation in work on analytical methods with the Ameri- 

 can Association of Feed Control Officials and with the Smalley Foundation 

 has been continued. 



Over 1950 samples of soil have been tested for residents of the state. 

 Two soils were tested by growing plants in the greenhouse for supposed harm- 

 ful constituents. 



Miscellaneous Samples 



Samples of feeds, fertilizers, and other materials have been analyzed for 

 residents of the state. Seventeen samples have been examined, involving 48 

 determinations.

Seed Inspection 



The regular seed inspection work for the State Department of Agricul- 

 ture was conducted as usual. During the year 2,547 samples were handled 

 in the laboratory. Of this number 431 were collected by the State Inspec- 

 tors and will be reported in Bulletin 370. A total of 2,116 samples were sent 

 in by seed dealers in compliance with the clause in our seed law which re- 

 quires that all vegetable and agricultural seed must have been tested for ger-
