EXPERIMENTS AVITH TURNIPS-Conclnded. 



Series I. , that had been in turnips for seven years, was set this year 

 to crossed tomatoes. First, because the demonstration was made that 

 lime is a satisfactory remedy for the club-root ; secondly, turnips do 

 not thrive as a continuous crop for many years, and thirdly, owing 

 to the limited space, the land was needed for other experiments. 



The reader who is interested in the club-root experiments, which 

 were the chief reason for holding turnips for seven years and twelve 

 consecutive crops upon the same land, will find the tabulations and 

 conclusions upon pages 410-413 of the report of this department for 

 last year. 



POTATO EXPERIMENTS IN 1901. 



Only Plot I., Series IL, was in potatoes the present season, and 

 this for the seventh consecutive year. The continuous cropping with 

 potatoes is not advisable and was only indulged in for the sake of the 

 experiments with soil fungicides for the scab. The results have not 

 been uniform in these experiments, and while sulphur gave much 

 promise the tests need to be many upon various kinds of soils before 

 final judgment is rendered in the case. Owing to the demands of 

 other lines of field experiments, mainly with plant breeding, the tests 

 with potatoes must for a time be considerably curtailed. 



Last season it was found that a shavings mulch gave a gain over 

 the adjoining uncovered land of nearly as 5 to 3. With this in mind 

 and the fact that the mulch seemed to protect the potatoes from scab, 

 it was concluded to continue Plot I., Series II. , in potatoes, although 

 for the seventh crop, which would very surely be a small one. The 

 early part of the season was unfavorable for potatoes and the crop 

 throughout the State is only a fraction of the average. 



The upper third of the plot was mulched with shavings that are 

 purchased in bales of 100 pounds each and used for stable bedding. 

 Fresh shavings to the depth of two inches were applied in July, and 

 thereafter no cultivation was given to this portion of the plot. 



The harvest was upon October 8th, and the following table shows 

 the results in number of marketable potatoes, weight of the same and 

 number of hills :
