Report on Project Work. 



Manure Economy Test. — This was somewhat upset by the 

 late spring, shortage of labor and insect injury, but the records 

 show consistent progress. 



Barium-Phosphate Test. — In the second season's test Barium- 

 Phosphate has shown no particular benefit over acid phosphate 

 as a carrier of phosphoric acid, and in several instances has 

 seemed less efficient. Two tests were carried out, — one sim- 

 ilar to that of 1919, the other with complete fertilizers, Barium- 

 Phosphate being substituted for acid phosphate in one mixture. 

 The crops under test were beets, carrots, cabbage, lettuce and 

 spinach. 



Martha Washington Asparagus. — The one-quarter acre plot 

 of this asparagus has developed in a satisfactory manner. The 

 first cutting was made the past season. Wide variation in size 

 and yield is noticeable in different plants. Plans are under 

 way for tests of individual plants to determine yields and 

 characters, with a view to an elimination of the less productive 

 units. 



Limited Variety Tests. — These tests have proved of much 

 interest, and point to some avenues of investigation which are 

 projected for the future. The strain and variety test of to- 

 matoes has been of much value, and indicates the possibility 

 that ecological factors are of more importance for this crop 

 than is commonly supposed. 



Greenhouse Cucumbers. — In the greenhouses there has been 

 a second test of cucumbers conducted in a similar manner to 

 that of 1919. The cold, cloudy spring interfered with this
