EXPERIMENT STATION RECORD. 



grown the previous year were disseminated among rice growers and pure strains 

 of stock seed of Nos. 19, 39, Go, 68, 153, and 154a are reported as available for 

 distribution. Of those already distributed No. 19 is the most noteworthy but 

 is suitable for fall culture only. No. 153, a strain of .Tai)an rice, yields as 

 heavily in 110 days as the more slowing maturing Hawaiian type of Gold Seed. 

 No. 65 yields well but is slow in maturing and lacks the flavor desired by 

 Japanese consumers. No. 152 failed to set seeds after the first year, during 

 which it had promised well. No. 73, anotlier Philippine rice, yielded well. 

 Seven Japanese varieties, 5 new and 2 previously tested, all promised well. 

 In a milling test of 4 varieties, Nos. 65 and 73 showed the best results, each 

 with 67 per cent of prime rice and 1 per cent of broken rice. 



With refei'ence to the Japanese claim that Hawaiian-grown rice is lacking in 

 strength, richness, and fattiness as well as in flavor, analyses made l)y tlie 

 Bureau of Chemistry of this Department are reported as follows: 



Compara'tive composition of imported and Haipaiian-groivn Jajxtn rices. 



Fertilizer experiment 1 of 1908 was a continuation of experiment 3 of 1907. 

 Its object was the determination of the residual value to the spring crop of 

 Japan and Gold Seed rice, of fertilizers ai)plied to the previous fall crop. The 

 data secured are summarized in the following table : 



Relative residual value of the various commercial forms of fertilizers on rice: 

 Paddy produced by 100 clumps of rice. 



" Plats 1 and 2 each received 40 lbs. of nitrogen ; plat .3, 45 lbs. of KoQ ; plat 4, 45 lbs. 

 of K2O and 61 lbs. of MgSOi ; plats 5 and 6, 25 lbs. of I'.Os each ; plat 7. 25 lbs. of PnOs and 

 62 lbs. CaO ; plat 8 received 28 lbs. of nitrogen, 17.5 lbs. of P2O5 and 31.5 lbs. of K2O from 

 a mixture of nitrate of soda, acid phosphate, and sulphate of potash ; plat 9 received 28 lbs. 

 of nitrogen, 17.5 lbs. of I'oOs and 31.5 lbs. of K^O from a mixture of sulphate of ammonia, 

 fish guano, reverted phosphate, and sulphate of potash ; and plat 10 received 28 lbs. of 

 nitrogen, 17.5 lbs. of P0O5 and 31.5 lbs. of K2O from a mixture of nitrate of soda, Thomas
