The results here presented show that the greatest average yield 

 of grain per acre was produced by the spring wheat and by the barley 

 from the first, and by the oats and the peas from the second date of 

 seeding. This also holds good in regard to the straw per acre, with 

 the single exception that in the case of peas the seed sown on the third 

 date produced a little higher yield than that sown on the second date. 

 In weight of grain per measured bushel, the first two dates of seeding 

 are decidedly the best with spring wheat, barley, and oats, but in che 

 case of peas the highest weights of grain per measured bushel were 

 obtained from the third and fourth seedings. It will be observed that 

 as the date of seeding was delayed the percentage of rust in the result- 

 ing crop was gradually increased, with only one slight exception. The 

 results indicate the importance of sowing spring wheat, barley, oats, 

 and peas in the order ^ere given, start'ng with the spring wheat and 

 finishing with the peas. 



An exceedingly important lesson may be learned from the results 

 of this experiment, which show that for every day's delay in the seeding 

 after the first week was passed in which the seeding took place, there 

 was an average decrease of 56 lbs. of oats, 53 lbs, of barley, 29 lbs, of 

 spring wheat, and 23 lbs. of peas per acre. 



Growing Grains in Mixtures for the Production of Grain and 



Straw. 



Within the past fifteen years, a large amount of experimental 

 work has been carried on in order to glean some reliable information 

 regarding the comparative values of growing grains in combination 

 in comparison with the growing of the same grains separately for the 

 production of grain and straw. Some of the experiments have been 

 completed, while others will need to be repeated in future seasons be- 

 fore the final conclusions can be drawn. The results of the experi- 

 ments already conducted are very interesting and quite suggestive. 



Four Kinds of Spring Grain Grown Separately and in Various 

 Combinations. For five years in succession, an experiment was con- 

 ducted in growing peas, oats, barley, and wheat, separately, and in all 

 the combinations which could be formed, having two, three, or four 

 grains in each mixture. This formed an experiment of fifteen differ- 

 ent crops, which were grown in comparison one with the other. The 

 experiment was conducted in duplicate each year. The results go to 

 show that the grain which was grown in mixtures produced larger 

 yields per acre than the same kinds of grain grown separately in near- 

 ly the whole of the tests. Of the different mixtures used, the oats and 

 barley gave the heaviest average yield of threshed grain per acre. 



Oats and Barley Mixed and Sown in Different Proportions. 

 It was decided in the spring of 1899 to conduct an experiment in sowing 

 nine different proportions of oats and barley in order to determine 

 which mixture and which quantity of seed would give the best results
