WOBURN EXPERIMENTAL FARM. 



REPORT FOR 1922 by Dr. J. A. VOELCKER. 

 Season. 



Beg-inning with a warm, dry October 1921, autumn cultivation 

 and sowing made good progress. The winter was marked by 

 little rain and only occasional frosts ; it was followed by a cold and 

 sunless spring which retarded the growth of winter-sown crops, 

 and by a very wet April which delayed the sowing of spring crops. 

 The early part of May was cold and wet, the latter hot and dry, 

 this continuing throughout June and making the obtaining of a 

 good swede crop difficult. In July rainfall was excessive, and, 

 from then to harvest, cold and wet weather, with absence of 

 sunshine, prevented the proper ripening of corn crops, all being 

 considerably damaged by rain. Mangolds, being put in early, 

 were an excellent crop, as also Potatoes, but Swedes were almost 

 an entire failure, and Hay, though a fairly large crop, was not of 

 good quality. 



The rainfall for the season was 25.41 inches, there being 193 

 days on which rain fell. The rainfall was heaviest in July 

 (4.02 ins.), and in April (3.89 ins.); in August and September, 

 2.07 ins. and 2.48 ins. of rain fell. 



FIELD EXPERIMENTS, 1922. 

 1. Contiyinous Gr(nvin(r of IF/zeai (Stackyard Field), //6'th Season. 



"Red Standard" wheat (10 pecks to the acre) was drilled on 

 October 10th, 1921. Farmyard manure (plot 11 B) was ploughed 

 in on October 5th, Rape Dust (plot lOB) on October 8th, and 

 mineral manures given to the several plots at the time of drilling 

 the wheat. The nitrogenous top-dressings were put on- May 17th 

 and June 17th, 1922. 



The wheat crop was cut on August 11th, stacked August 29th, 

 and threshed on December 22nd. 



The results are given on page 62. 



The crop results were very similar to those of 1920. 



The main features shown are : — The unmanured produce 

 averaged 8.5 bushels of corn with 7 cwt. of straw per acre; farm- 

 yard manure gave only 2 bushels more per acre, Rape Dust doing
