At Maigana, N. Nigeria, Japanese Buckwheat is reported 

 a failure as " it does not appear to stand the very hot chmate '' 

 (Rae, Rep. Agric. Dept. N. Provinces, 1914, p. 12). It should, 

 however, be tried on the higher altitudes ; it is gf o\vh to a small 

 extent in the neighbourhood of Nairobi and in the districts 

 farther towards Lake Victoria (Bull Imp. Inst. 1906, p. 274) ; 

 in Uganda it has been found to yield about 500 lb. of seed per 

 acre (Ann.. Rep, Dept. Agric. Uganda, 1914, p. 13) — not a big 

 crop perhaps ; but "sufficient to show that the plant can be 

 grown to maturity in Tropical Africa — and the plant seems to 

 have been grown with some success in Dominica for bee-feeding 

 — '' 6 in. high 19 days after sowing, developing into fairly strong 

 dwarf plants and giving a profusion of floAvers for four weeks '' 



(Ann. Rep. Bot. St, Dominica, 1907-08, p. 34)!

Propagated by seed, of which from one to three bushels are 

 required to sow an acre. The plant Avill not stand frost; but 

 requires a w^arm chmate and will grow in comparatively poor 

 soil ; germination takes place in from 5-6 days after sowing, 

 maturing in 3-4 months ; but also stated to mature in a shorter 

 period than any other grain-crop, 8 or 10 w^eks being sufficient 

 under favourable conditions (CycL Amer. Agric. ii. p. 219). 

 The jdeld may be from 3-6 quarters (qr. 392 lb.) per acre.
