IIKI.I) CROPS. -J.*'.'. 1 



potatoes produced much better yields than Beed of the same varieties grown in the 

 district the previous year. Whole tubers for seed gave a larger total yield than 

 either sets with single eyes or plant- from cuttings. The fertilizer tests with mangels 

 showed a large increase in yield from the use of barnyard manure and commercial 

 fertilizers. Of 6, varieties, Yellow Globe produced the heaviest weight of crop, bul 

 Golden Globe, Golden Tankard, and Sugar Mangel were superior to it in quality. 



In Staffordshire cooperative fertilizer tests were made on grass land, and experi- 

 ments were conducted with potatoes, mangels, and swedes. In the fertilizer tests on 

 grass at Blurton I cwt. of nitrate of soda and 5 cwt. of basic slag per acre, applied 

 singly, gave an increase of 5 cwt. of hay per acre, bul when given together the yield 



was li" greater than on the check plat. Barnyard manure produced a g I increase, 



hut wa> not profitable. At Knightley LO tons of barnyard manure gave a large 

 increase in yield, but the quality of the grass was reduced. The nexl largest increase 

 was obtained with 3 cwt. of kainil and l cwt. of nitrate of soda per acre, and the 

 same increase resulted where 5 cwt. of basic Blag was given in addition. Tin- use of 

 5 cwt. of basic slag alone per, acre gave the increase at t he Lowest cosl per cwt. of hay. 

 The best results .;; .Man- were secured from an application >>\ barnyard manure, 

 together with a c plete dressing of commercial fertilizers. 



Of 12 varieties <>i' potatoes, Royal Kidney, Factor, and Up to Date gave the best 

 yields and also ranked well in quality. In a fertilizer test the commercial fertilizers 

 had little effect, and the heaviest yields were obtained from the use of 2(1 tons of 

 barnyard manure per acre. 



Memoranda of plans for arid farm investigations ( Utah Sta. Circ. 8, />/>. .".>, 

 dgms. 6). — This circular contains outlines of the arid farm investigations for 1905 on 

 the 6 experiment farms established under the direction of the State legislature, ami 

 gives complete instruction with reference to conducting the experiments and to the 

 management of the farms in general. 



Effects of manures throughout rotations of crops, I>. A. Gilchrist County 

 Northumb. Ed. Com., I!"/. .;. pp, 15-22). — Fertilizer experiments were conducted on 

 a light sandy loam Boil throughout 2 courses of a rotation. 



In the first rotation turnips, oats, hay, and oats, and in the second, swedes, 

 barley, hay, and <>ats were grown, in the order named. The standard application 

 ofcommerical fertilizers per acre consisted of 1 cwt. of sulphate of ammonia. 5 cwt. 

 of superphosphate, and I cwt. of muriate of potash, containing 25 lbs. of nitrogen, 75 

 M's. of phosphoric acid, and 50 lbs. of potash, and the application of barnyard 

 manure of 10 tons per acre 



Barnyard manure was of greater value than commercial fertilizers, but both were 



Satisfactory. Where the 2 were used on the same plat it was found best to apply 

 the manure to the swedes and to use the commercial fertilizers for the hay. 

 Twenty tons of barnyard manure did not prove profitable, and doubling the quan- 

 tity of commercial fertilizers was of benefit only when divided between the swedes 

 and the hay. The omission of potash nearly obliterated the gains obtained from 

 the application of commercial fertilizers. The use of LOtonsof barnyard manure 

 made up the deficiency of potash in this soil. 



Forage crops, E. R. Lloyd 1 Mississippi Sta. Rpt. 1904,pp. IS, 14). — Winter wheal 

 was grown for hay and followed by cowpeas sown at the rate of 2 bu. per acre. The 

 cowpeas came up with Johnson grass and gave 2 cuttings. The yield of hay from 

 peas and wheat was 3.85 tons per acre, obtained at a cost of $3 per ton put into the 

 harm < >atswerecut for hay in the dough stage and followed by Early Amber sorghum, 

 sow n at the rate of 2 bu. per acre. 



Sorghum gave 2 cuttings, and the total yield for oats and sorghum was 6.25 tons 

 per acre, costing $2.77 per ton in the rick. Two acres of alfalfa, which suffered to 

 some extent from the lack of drainage, furnished pasturage for 14 pigs for 1 month
