546 EXPERIMENT STATION RECOED. 



Three plats of 16 square meters each (about 172 ^sq. ft.) were used in the 

 experiment, each plat being first treated with a similar complete fertilizer. In 

 the first plat 9 holes were made and 50 cc. of carbon bisulphid was poured into 

 each hole 10 days before planting, the holes being afterwards filled in and water 

 poured on the surface. In the second plat 40 gm. of sodium nitrate was applied 

 as a top-dressing, one portion on May 3 and the other on June 1. The third 

 plat served as a control. The results show an increased yield of mulberry leaves 

 of 44 per cent on the bisulphid of carbon plat, as compared with no perceptible 

 increase on the sodium nitrate plat.
