March, 1933] Agric. Research in New Hampshire 19 



beans, probably with uniform stand 'no difference in yield; Bonny 

 Best tomatoes, virtually no difference. 



Of 19 varieties of tomatoes tested, Pritchard seemed to be the most 

 promising of the new sorts. Very late varieties like Norton and 

 Greater Baltimore suffered seriously from point rot under the very 

 dry conditions of 1932. 



Eighteen strains of the third generation of Black Beauty-Dwarf 

 Purple eggplant cross were grown and considerable variation in uni- 

 formity noted. Black Beauty, an excellent quality variety, is too late 

 in maturity for successful culture in this section. Further tests will 

 be made with seed from these plants and from five other strains.

Grapes, Strawberry, Apple Varieties Tested 



Ontario was the earliest grape to ripen and it produced a fair crop, 

 according to a report on variety tests of fruits by L. P. Latimer. 

 Other promising sorts were the Niagara, "Winchcll, Caco, CampbelFs 

 Early, Clinton, Herbert and Beta. 



The Worden did not seem to have enough foliage to mature its 

 heavy crop satisfactorily; the Duchess produced a fair crop; the Port- 

 land did not do well enough to warrant recommending for this section. 



The Cortland apple continues to win approval for the size and color 

 of its fruit and its yielding ability. It hangs well to the tree. It 

 seems more subject to attack by railroad worm than most other vari- 

 eties and it apparently is one of the kinds most susceptible to drought 

 spot and cork. Although not an early variety Golden Delicious was 

 also observed to be preferred by the adult flies of the railroad worm. 



The New Howard 25 or Supreme strawberry materially outyielded 

 the older Howard 17 or Premier. It is a pistillate variety, requiring 

 some variety like the Premier planted with it. Later in ripening, it 

 is more resistant to the "yellows" which has been affecting the Premier 

 in recent years. 



Among the newer varieties of raspberries Chief made the greatest 

 number of new canes. Viking made fewer but taller and stouter ones. 

 Lloyd George needs the support of a trellis. (Hatch Fund) 



Mineral Fertilizers Doubtful for Strawberries 



Ten years of observations on strawberries by L. P. Latimer show 

 that under New Hampshire conditions mineral fertilizers are of doubt- 

 ful value. 



Two treatments were used last year, each on 11 plots of berries, and 

 these were checked with 11 untreated plots. One treatment consisted 

 of 250 pounds of acid phosphate per acre. 125 of sodium nitrate and 60 

 of potassium chloride. The other included 250 pounds of acid phos- 

 phate, 75 of tankage, 90 of sodium nitrate and 60 of potassium chloride, 



High-Protein Ration for Battery Brooding 



A ration carrying even more than 20 per cent protein may be ad- 

 visable for batteiy brooding of chicks, according to three years of re- 

 search by A. E. Tepper, T. B. Charles, and F. D. Reed. This showed
