CROTALARIA 



As this plant is not relished by animals and the seeds 

 are no good for food, it can only be used as a green manure. 



When planted between the rows, this shrub, during 

 florescence, may yield an average of 33 to 35^- tons of green 

 matter to the hectare, which, counting o'3i per cent, of 

 nitrogen, is equivalent to 102 to 109 kilos over that area. 



M. Boname has obtained excellent results from a number 

 of trials at the Agronomic Station. The plant develops 

 splendidly without the least injury to the small canes. 

 Three or four seeds are sown together in holes from 50 to 

 60 cm. apart. When the plants are from 10 to 20 cm. high, 

 the more weakly ones are weeded out and one or two left. 



Among all the varieties tested, those succeeded best 

 which were most acclimatized. This is usually the case; 

 species which are indigenous or have been cultivated for a 

 number of years are more hardy than varieties newly intro- 

 duced, which, though they may have special qualities of 

 their own, are nevertheless less useful because less estab- 

 lished. 



According to M. Boname, three different cultivations 

 gave, for a crop in full flower when ploughed in, the fol- 

 lowing results : — 



A. — Full cultivation, yield per hectare ... ... 32,220 kilos 



B. — CuUivation between canes, every alternate row ... 11,680 ,, 

 V-^. ,, ,, ,, ... 7,110,,
