32 A ^EW TYPE OF RED CLOVER. 



PREPAKATION OF LAND, SEEDING, AND SUBSEQUENT TKEAT5IENT. 



Field F, which was used in making the green-matter determina- 

 tions, was sown to Canada field peas in 1902, and in 1903 was used 

 in the variety testing of cereals. The field was fall-plowed in 1903 

 and in the spring was disked and harrowed preparatory to seeding 

 with clover. Spelt was used as a nurse crop. The clover seed and 

 the spelt were mixed and sown with a drill. 



Field W, from which the data as to field-cured hay was secured^ 

 bore a crop of fodder corn in 1902, and was manured and again sown 

 to fodder corn in 1903. In preparation for the clover it was thor- 

 oughly disked and harrowed. The clover seed was drilled in to a 

 depth of from H to 2 inches, having been first mixed with the Min- 

 nesota No. 169 wheat, which was used as a nurse crop. 



No treatment such as pasturing or clipping was given the field 

 after the removal of the spelt and wheat. 



WEATHER CONDITIONS DURING 1904 AND 1905. 



The weather throughout the season of 1904, despite the fact that 

 the temperature in most months was a little below normal, was 

 quite favorable to securing a good ''catch" of clover. The last 

 killing frost in spring occurred on ^lay 15, and the first in autumn 

 on October 6. There was a plentiful supply of moisture at all times, 

 the precipitation of every month during the growing season exceed- 

 ing the normal. 



According to notes taken shortly before the first killing frost of 

 autumn, there was a fair stand on all plats at that time. The weakest 

 strains were those from Tennessee, Orel, and Kief, while among the 

 most vigorous were those from Ohio, Indiana, Wisconsin, and Iowa. 



The winter of 1904-5 was rather severe on the whole, the means 

 for both January and February being several degrees below normal. 

 The minimum temperature recorded was 26° F. below zero. 



No marked loss due to winterkilling was noted on any of the 

 varieties under experiment, but on account of the coolness of April 

 practically no growth was made until the last week of the month. 



COMPARATIVE CONDITION OF DIFFERENT STRAINS OF CLOVER IN THE SPRING OF 1905. 



On May 13 observations were made on the comparative condition 

 of the stand on all the plats. According to these, of the seeds from 

 domestic sources the strains from eastern Ohio, northern Indiana, 

 and the commercial samples made the best showing at this time. 

 The poorest of the domestic strains at this time were those from 

 Tennessee, Missouri, Nebraska, Michigan, and Illinois. The best 

 of the Russian strains were Nos. 15 and 17, from the Kief and Mogileff 

 governments, respectively, while the poorest were Nos. 16 and 18, 

 from Orel and Courland.
