In the experiment reported in Table 6 Crotalaria striata and C. 
spectabilis were seeded at the rate of 30 pounds per acre, while @. 
usaramoensis and C’. lanceolata were seeded at the rate of 15 pounds 
per acre. The resultant stands of the plants per unit area were 
C. striata, 243; C. spectabilis, 58; C. usaramoensis, 55; and C. lanceo- 
lata, 76. The C. spectabilis evidently contained much hard seed, as 
the germination was very poor, with a resulting poor stand. This 
was also true of C. usaramoensis and C. lanceolata to a lesser extent. 
Plants of C. spectabilis continued to emerge all summer. This gave 
(’. striata a decided advantage, as a good early germination was se- 
cured, and consequently the yields were higher. 
There are several points of interest in the preceding tables of 
yields. The Crotalaria species were cut back to a height of 4 to 6 
inches, and all continued growth. The total yields for the season 
were much reduced by cutting back, although hay of much higher 
quality and higher protein content was secured by cutting two and 
three times per season. 
As previously mentioned, rather late planting of crotalaria is ad- 
visable if desired for hay, as early-planted crotalaria will be very
