EXPEKI31E^'TS IN THE CULTURE OF OATS AND WHEAT, R. J. 



liEDDiNG (pp. 73-78).— Fertilizers on oats (pp. 7o-75).— An experiment 

 on 10 tenth-acre plats tft study the needs of the soil for growing oats. 

 The soil, a '-gray, gravelly soil, with hard red clay subsoil, made a fair 

 crop of oats in 18U0, followed immediately Ly peas, which Avere con- 

 verted into hay. * * * The unaided productiveness of the soil 

 increased from plat 1 throughout the series, plat 1 being of poorer 

 (iuality than any." Xine of the plats received all three of the essential 

 tV-rtilizing ingredients in varying amounts, supplied in the form of super- 

 phosphate, muriate of potash, and cotton-seed meal; one plat remained 

 unmanured. Three bushels of Appier oats per acre were sown on all 

 the plats. The results as tabulated "indicate very decidedly that 

 nitrogen is the most effective element as a fertilizer for oats on this 

 land. In this case the cotton-seed meal was the only element which 

 paid a good profit on cost, whether in single, double, or treble doses 

 (32, 04, and 90 pounds per plat). The experiment was not sufficiently 

 elaborate to indicate just what proportions of the different elements 

 would give best results."

Fertilizer test with bush beans (pp. 81, 82). — The land used for the trial 

 was a young pear orchard in which the trees were set the previous year. 

 The soil was a sandj^ clay underlaid by heavy clay subsoil. The 

 experiment included 24 rows each " an eighth of an acre long." On these 

 superphosphate 400 jjounds, muriate of potash 100 pounds, and cotton- 

 seed meal 400 pounds or nitrate of soda 200 jjounds per acre were used 

 singly, two by two, and all three together; all three together with 

 double the above amounts, applying the nitrogenous fertilizers either all 

 at once or in two separate portions ; and barnyard manure 15,000 pounds 

 used alone. Four plats remained unmanured. Early Valentine beans 

 were planted in hills a foot apart on all the plats. The yields of beans 

 at four separate pickings are given for each plat. According to these 

 tlie total yields of the four unfertilized plats ranged from 1.54 to 4.07 

 ])ounds per plat. The yields were larger when nitrogenous fertilizers 

 were used alone or combined than where muriate of potash and super- 

 jihosphate were used, eitlfer alone or combined, without nitrogen. Where 

 no nitrogen was used the yield was about the same as on the unferti- 

 lized plats. The largest yield (8.47 pounds per plat) occui'red where
