The resnlts of experiments on pasture indicated a general improvement of feeding 

 over mowing the grass. Including rye grass in the seed mixture gave a marked 

 increase in the hay crop. The thickly-seeded plats continued to give the heavier 

 yields. The use of lime produced a marked effect on the yield and general appear- 

 ance of the plats. In another experiment 5 cwt. of mineral superphosphate per 

 acre gave a heavier yield of hay than 8 cwt. of l)asic slag. There was no apparent 

 increase in the clover where basic slag was used. 



Cooperative field trials ( f/n/y. Ext. Col. Heading, Agr. Dcpl., Aun. lipi. Field 

 Trials and Expts. 1903, pp. 21-39). — The results of cooperative trials are Ijriefly 

 reported. The yield of mangels, the quantity of important constituents produced 

 per acre, and the percentage of water contained in the roots are shown in the follow-

In a fertilizer test with mangels, carried out at West Wycombe, a plat receiving 

 2 cwt. of nitrate of soda and 4 cwt. each of super2)hosphate and kainit per acre, 

 yielded 26 tons per acre, being the best yield in the test. A 2)lat receiving 2 cwt. of 

 common salt in addition to this application gave the same yield, while the plats 

 receiving no manure or incomplete applications produced considerably less. 



Experiments were also made with different quantities of seed and different widths 

 of drilling barley and oats. In both tests the drills were 7J and 11 in. apart. Barley 

 was sown on 6 plats at rates ranging from 1 to SJ bu. per acre, making a difference 

 of 2 bu. of seed between each 2 contiguous plats in the series. The yield of barley 

 was ])ractically the same on both series of plats, but the wider drilling jiroduced the 

 most straw. The proportion of small kernels as well as the average weight per 

 l)ushel was greatest on the narrow drilled plats. On the wide drilled i)lats the 

 largest yields were obtained from the use of 2 bu. of seed per acre. The weight per 

 bushel in both distance tests was greatest from the smaller quantities of seed. 



In the experiments with oats the seed used ranged from 2^ to 5 bu. per acre, also 

 making a difference of ^ bu. between any plat and the next one to it in the series. 

 The total yield of grain and straw was the best on the narrow-drilled plats. The 

 largest quantity of good grain was obtained from the narrow drilling, and from 2^ 

 bu. of seed per acre. Good results were also secured where from 4 to 5 bu. of seed 

 were used. 



Tests at Burghfield of fertilizers for hay on clay loam soil with very stiff clay sub- 

 soil illustrated the lasting effect of ))asic slag, superphosphate, and kainit, these fer-
