Green-manuring Experiments. 



(a) Stackyard Field. Series A. 



The land was ploughed in September, 1913, after the green 

 crops of tbat year had been fed on by sheep. On October 13, 

 "Square Head's Master" wheat, previously dressed with 

 sulphate of copper, was sown at the rate of 9 pecks per acre. 

 It came up well and looked flourishing over all the plots until 

 about May, 1914, when, through lack of rain, it lost its colour 

 considerably. The "tares" plot at this time appeared to be 

 standing the drought rather the best. The differences, how- 

 ever, were not marked, and subsequently the "rape" and 

 " mustard" crops improved, the rape plot looking, if anything, 

 the better. The wheat ci'op was cut on August 15, and, on 

 August 20, it was threshed direct from the stook. The results 

 are given in Table IV.

It will be seen that the rape gave the best return both in 

 corn and in straAv, mustard coming next, while the crop after 

 tares was the smallest of the three. The difference in quality 

 between the different lots was not much. They were none of 

 them good samples, being below the season's average, and also 

 low in gluten. The wheat from the mustard plot contained a 

 good deal of small blighted grain. 



{b) Lansome Field. 



The land was ploughed after the oat crop of 1913, and left 

 until the spring. 



On April 8, 1914, spring tares were sown on plots 1 and 2 

 at the rate of two bushels per acre, and, on May 20, rape seed 

 at the rate of 8 lb. per acre was drilled on plots 3 and 4, and 

 mustard on plots 5 and 6 at the rate of 10 lb. per acre. The 

 green crops grew very fairly, and on July 16 were ploughed in 

 as usual. A second crop of tares was sown on July 2^, and
