Nubbins. — It also shows that in most crops there is a con- 

 siderable proportion of "nubbins," i.e. small ears (cf. Fig. 62) 

 — often only 2 to 4 ozs. weight — which are imperfectly de- 

 veloped owing to inadequate pollination, or other causes. A 

 three-quarter stand of 6,534 bearing plants per acre, yielding 

 10 muids of shelled grain, shows the low average of 4-89 ozs. 

 of grain per ear, which is only 66 per cent of the average 

 weight of the 150 medium ears mentioned above (p. 137), and 

 is only 48 per cent of the average weight of 100 selected ears.
