Chemical composition of corn, silage, cow-peas, and soja 

 beans in South Carolina, J. B. McBryde, C. E. (pp. 55-79). — In 

 view of the fact that few, if any, analyses of corn and forage crops 

 grown in South Carolina had been made, the investigations reported in 

 this bulletin were undertaken. The samples analyzed were from crops 

 grown on the farms of the experiment station and from corn grown for 

 the prize recently offered by the American Agriculturist. 



Corn. — The tabulated data of the analyses include the composition 

 and the fertilizing constituents of the grain, cob, and shuck ; the av- 

 erage composition of the grain, cob, and shuck of corn grown at the 

 experiment farms; and per cents of grain and cob, and of moisture in 

 corn grown for the prize. In other tables the results of similar anal- 

 yses of Western and Northern corn made at the stations in Connecticut 

 and Massachusetts are compared with those of the corn grown in South 

 Carolina. The weights of different parts of the corn plant expressed in 

 l)er cents are also given as found in experiments in Missouri, Con- 

 necticut, and South Carolina. Conclusions are drawn as follows : 

 "(1) that in an average crop of Indian corn the ear is by weight 

 approximately one half the entire crop; (2) that about four fifths of 

 the ear is grain ; (3) that about one half of the stover is stalk." At- 

 tention is called to the desirability of feeding the entire plant instead 

 of throwing away the stover, as is commonly done in that section. 



More than 20 per cent of the crude protein aud 50 per cent of the carbohydrates 

 are contained in this much neglected portion of the crop. Such waste of valuable 

 constituents is not an inconsiderable matter, bnt one which would certainly seem 

 to warrant the trial of some judicioiis system of feeding whereby it might be avoided. 

 The grain and cob should be ground together, and the entire stover run through a
