Synopsis. — Phiiitiiiii' May 1.', cultiv.iliiiL!; twice in a. season, listing acMonipiinied with 

 <leep fulture, subsoiling (5 months or longer heloie ])lantiug, and planting late 

 varieties gave best I'esnlts. 



Of 7 plautiugs oil tweiitietliacre plats at intervals of 1 week from 

 April 18 to May oO, tlie best total yield was given l)y the ])laiiting of 

 May 2. On 30 plats the cultivation varied from as often as 3 times a 

 week to as seldom as once in 4 weeks. The results were contradictory, 

 the averages for 3 years giving the best yields on plats cultivated once 

 a week and once in 3 weeks. Two cultivations in a season gave better 

 returns than 4 or (I. On the average for 3 years listed corn given deep 

 culture gave best returns, followed by surface ])lanted with deep culture. 



Three eightli-acre plats were subsoiled, one in the spring and one in 

 the fall of 1894, and one in the spring of 1895. The returns from the 

 first two were greater and from the last one less than the yield of the 

 check plats. 



In a trial of butt, middle, and tij) kernels for seed the results were 

 contradictory, 



A list is given of 28 varieties tested. In a comparison of red Kafir 

 corn with Indian corn (3 plats were used, 2 for each variety. The red 

 Kafir corn yielded nearly twice as much gram as the most prolific 

 Indian corn. 



In a comparison of early, medium, and late varieties, the late variety 

 gave the best yield and the early one the i^ourest. 



Field experiments with corn, H. J. Waters and 0. M. Conner 

 {Missouri Sta. Bid. S.^\ pp. o:J). — This is acontinuntion of Avork reported 

 in BuUetin 14 of the station (K. S. K., 3, p. 27), 



Varietii test (pp. 7-12). — In 1895 5G varieties were grown and the 

 yields are tabulated. Of the dent varieties the highest average yield 

 for 3 years was produced by Golden J>eauty, 57,4 bu. i)er acre, followed 

 by Leaming, Piasa King, Saint Charles White, and Chester County 

 Mammoth. 



Fertilizer test (pp. 13-17). — In 1891, as in 3 889, applications were 

 made at a uniform rate of 10 tons of barnyard manure per acre, fer- 

 mented and unfermented, solid horse and cattle manure alone, and 

 solid and liquid manure combined. These were applied both on the 

 surface and idowed under. The tabulated data cover 3 years. The 

 authors state that from the land where fresh barnyard manure was 

 applied twice in .') years an average increase in yield was obtained of 

 30,0 per cent. From the combined solid and licpiid manures larger 

 yields were obtained than from solid manure alone. Horse manure 

 produced larger yields than cattle manure. Plowing manure under 

 was better than applying it on the surface.
