Commercial Value. 



In estimating the commercial value both the weight of crop per acre 

 and the nutritive composition have to be taken into consideration. It will 

 be observed from the above table that there is considerable variation in 

 both of these qualitie.s — Hickory King showing the greatest weight per 

 acre (26 tons 5 cwt.), while North Western Dent, although the smallest 

 yielder in weight, is the richest in protein and carbohvdrates. 



Comparison with such a commonlv used food .stuff as bran will perhaps 

 best serve to illustrate the value of the different varieties of maize based 

 on weight of crop and nutritive value. Taking the average analysis of
