EXPERIMENT STATION RECORD. 



In judgiiis' tliesG results tlie somewliat abnormal character of the 

 season nuist be borne in mind. The questions of the influence of the 

 climate on the (;rop under more normal conditions and during cultiva- 

 tion for a series of years have yet to be studied. 



The South Finnish white oat varieties lead in the amount of protein 

 produced, with an average yield of 18G.7 lbs. of protein per acre. The 

 single variety yielding the largest quantity of protein per acre was 

 Sordavala, 288 lbs. 



Oats from different parts of the sheaf. — Oat kernels from different parts 

 of the ear were analyzed, with the following results:

Experiments with Irish potatoes, E. S. Richman ( Utah Sta. Bpf. 

 1893, pp. 181-190). — These consisted of experiments with entire small 

 potatoes as compared with cuttings of the same weight from large 

 potatoes, depth of plowing, effect of manuring on starch content, and 

 tests of 33 varieties. This is the fourth year of the experiment com- 

 paring small uncut potatoes with cuttings of equal weight from large 

 potatoes. Each year the large seed tubers were selected from the crop 

 propagated by cuttings and the small seed tubers from the crop propa- 

 gated by uncut small tubers. The results in pounds per j)lat of one- 

 twentieth acre for the 4 years were as follows :

The differences due to character of seed were but slight. 



Plowing to a depth of 6 in. gave, with potatoes, as also with cabbage 

 and sweet corn, better results than deeper or shallower preparation. 



The results of a comparison of the starch content of tubers grown 

 on unfertilized plats and on plats manured at the rate of 35 and 70 

 tons of manure per acre are somewhat conflicting, but the author 

 draws the conclusion that constant excessive manuring tends to 

 decrease the amount of starch.

 179, 180). — The yield of potatoes on an unirrigated plat, on a plat irri-
