the net gain from $32.18 t<» .'fHj.C):! per a<if. Lime used alone also resulted in 

 a loss. 



A preliminary experiment conducted in oniou .seed production indicated that 

 early plantinj? is advi.sable where nia.vinnini yields are to be secured. Medium 

 sized bulbs, LIT* in. to 1.5 in. in diameter j.'avi> a ^I'eatly increased yield of seed 

 over either the larger or smaller bulbs. It is (juestioned whether medium sized 

 bulbs will always prove to be better yielders than larj;er bulbs, but on account 

 of the high cost of larger bulbs the medium size is preferred. 



Some work in the selection with sweet corn seed was started in 1918, and 

 work was also started to determine the value of imported potato seed when 

 compai'ed with Indiana grown seed. The Indiana grown seed compai-ed very 

 favorably witli and in most tests was better than imported seed stocks. The 

 work will be continued.
