set of fruit. Assistant Research Professor V. A. Tiedjens. A preliminary report 

 was published as Bulletin 225, "Yellow Pickle in Greenhouse Cucumbers." 



14. Cold resistance in sweet corn in its relation to quality, size and earliness. 

 Assistant Research Professor V. A. Tiedjens. 



15. The control of eggplant wilt caused by Verticillium albo-atrum R and B. 

 Assistant Research Professor E. F. Guba. 



Microbiology. 



4. Addition to "Study of nitrogen fixation in the presence of, or as the result of, 

 growth of legumes versus non-legumes under certain defined agronomic conditions. 

 Assistant Research Professor L. A. Bradley. 



Pomology. 



1. Study of interrelation of stock and scion in apples. Research Professor J. K. 

 Shaw. Progress report, "Effect of Stock on Scion," in Bulletin 226. Project 

 started in 1912, on the basis of a twenty-year program. As the orchards were set 

 out on leased land, it must come to maturity before 1932. Significant differences 

 in the interrelation of stock and scion have been shown. 



2. A study of the tree characters of fruit varieties. Research Professor J. K. 

 Shaw. Supplements the project on Leaf Characters of Apple Varieties which is 

 the basis of present work in nursery certification. 



3. The genetic composition of peaches. Research Professor J. K. Shaw. Scien- 

 tific Contribution 40, "Autumn Development of Peach Fruit Buds," is a report 

 on certain studies made in connection with this project. 



5. Comparison of cultivation and sod mulch in a bearing orchard. Research 

 Professor J. K. Shaw. Scientific Contribution 39, "Sod-Nitrate vs. Cultivation 

 in Apple Orchard." Trees in nitrated sod mulch have made better growth and 

 given larger yields than trees under cultivation. Results differ from those secured 

 in other sections, but apparently are fairly typical of much of the orchard area 

 of southern New England. 



8. Test of cover crops for apple orchards. Research Professor J. K. Shaw. 



9. Testing methods of pruning. Research Professor J. K. Shaw. Progress 

 report in Bulletin 226, "Pruning Young Apple Trees." 



12. Apple variety fruit spur study. Research Professor J. K. Shaw and Assist- 

 ant Research Professor C. P. Jones. 



13. A study of varieties of tree fruits. Research Professor J. K. Shaw. A 

 routine project, consisting of the taking of many records on some thousands of 

 fruit trees annually, these being available for classification in terms of variety, 

 soil, fertility treatment, management, etc. 



14. Stud}'- of the relation of winter injury of brambles to differential fertilization 

 with potash salts. Research Professor J. K. Shaw, Assistant Research Professor 

 C. P. Jones and Professor A. V. Osmun. 



16. Test of different amounts of nitrate of soda. Research Professor J. K. Shaw. 



17. A study of the cultivation of the high bush cranberry. {Viburnum opulus). 

 Research Professor J. K. Shaw. 



18. Comparison of cultivation and heavy mulching for apples and pears. Research 

 Professor J. K. Shaw. Heavy mulching with material brought into the orchard 

 has produced a growth typical of a plentiful nitrogen supply. Chemical analysis 

 has shown enormous production of nitrates beneath the mulch. 



19. A study of the effects of fertilizer limitation on fruit plants. Research 

 Professor J. K. Shaw. Scientific Contribution 38, "Some Unusual Results in 

 Fertilizing Fruit Plants." Carried on on the old North Soil Test, full reports 

 of which were published in Bulletin 212. The trees have a staged condition brought 

 about by many years of differential fertilization. Differences in growth are 

 enormous.

 7, "Broodiness in Relation to Fecundity in the Domestic Fowl."

 Poultry for Egg Production"; also Bulletins 211 and 215, pubUshed several years 

 ago.
