SOY BEANS IN BENGAL, BIHAR AND ORlSSA. 



it will probably be necessary to introduce satisfactory early 

 types. 



Soy Beans are grown during the rainy season in Bihar. 

 The local varieties (Types I — IV) resemble the other Bhadai pulse 

 crops in that they ripen off at the same time of year irrespective 

 of the date on which they are planted. These late varieties 

 normally ripen after the middle of December, but can be sown 

 from the end of May to the beginning of September. If they 

 are planted late in September or early in October the size of the 

 plant is much reduced and the date of harvesting may be some- 

 what later. The varieties grown in the Darjeeling hills have a 

 somewhat shorter period of growth and were ripe in November 

 at Sabour in 1911. None of these short season varieties have 

 been found to have spread into the plains. A statement is given 

 showing the life periods of the Bengal types. (Table VIII.) 



As a result of some observations made by Ball (12) and 

 Piper and Morse (9) in America it has been thought that a 

 variety may progressively change from early to late, but the 

 evidence is at present by no meaus conclusive. The observa- 

 tions made by us at Sabour show that newly imported American 

 varieties take a considerably shorter time to mature at Sabour 

 than in America, but that plants from acclimatized seed mature 

 somewhat later than those from freshly imported seed. A 

 statement of our observations is given below : —
