Fertilizers on siceet potatoes (pp. 150-152).-A prehnunary expernnent 

 en 12 twentieth-acre phits on the tarm of G. E. Farry. The fcrtihzers 

 consisted of nitrate of soda, 100 and 320 ponnds per acre, apph.-d 

 all at one time. May 20, or half then and the remainder June LO, both 

 alone and in eonnecti.m with superphosphate 320 pounds and muri- 

 ate of potash 100 pounds per acre. One plat received the nuxture ot 

 superph<.sphate and potash witlmut nitn.ovn. another 20 tons ot barn- 

 yard manure per a^re, and tw<. remained unmanured. Tlie sod was 

 Very li-ht ami sandy. TIm' tal.lr of yields shows the yield ot merehaut- 

 ■tble i.otators to have been lar-est (120 bushels per acre) where barn 

 yard manure was used, an.l next largest (85 to 00 bushels) wlu-re nitrat- 

 of so.la was us,.! with superphosphate and potash. The doulde amount 

 (Sn) pounds) of nitrate ..f so<la sceuied t.> be without benefit to the en.,,, 

 and where nitrat<i was used alone there was seareely any in.reasr ni 

 yield over that of the unmanured plats. "The yield of merehantabl.- 

 potatoes was inerc-asrd over 0(. per eent by the use of phosphoric a<M<l 

 •md potash'' without nitrogrn. All..wing 75 rents per bushel lor the 

 .sweet potatoes, -wherever nitrate was used alone, exeept on plat 2, 

 there was a loss ranging from 25 cents to $S. There was a profit ir..m 

 the use of n.ineral <'lements alone [sup.-rphosphate and muriate ot pot- 

 Mshl and also in every ease where the eon.ph'te fertili/.er was used, 

 though not in any case as great as the profit tnMu the barnyard manur. 

 when the eost of the manure is rated at $1.50 per ton." 



Fertilizers upon peach trees (pp. 153-155).-A report is given for 1800 

 of t^e experiments carried on since 1887 <m the farm of vS.C. Dayton, 

 the general plan of whieh was referred to in connection with the report 

 for 1880 (see above, p. 203). A summary is given of the results m 188< , 

 1888, and 1889. The crop in 1890 was " a eomplete failure." 



Another experiment was commeneed in 1890 on the farm of S. ^. 

 Voorhees, trees being set on 3 fourth-acre plat* and eorn plant.d 

 between the rows. Tlie yield of corn is tabulated. 



\LFAiFA(pp. 150-100).— This is a eoutinuation of the experiment 

 comnu'm-ed in 1887 (see ab(»ve, p. 295), being a report of the yield of the 

 drilled and th.' broadcasted plats in 1890 at four suecessive cuttings— 

 Miv "2 June 21, Julv 30, au.l ^eptend)er Hi. " The total yield ot gre. n 

 fodder per acre was 22.7 tons from the drilled plat and 22.45 tons fr..m 

 the broadcasted plat." . 



The adaptability of this crop was further tested on another pie<?e of 

 land at the college farm and on three other tarms in difterent parts of 

 the State, the seed being broadcasted on plats onefi.urth tooue halt an 

 a<3re in area. The seed and fertilizers were furnished by the station. 

 In every case except at the college the growth of alfalta after the first
