195 CORN IN A ROTATION. The rotation of crops thought desirable for the University farms, subject to variation, is corn, two years; small grain, one year; grass and clover, three years, followed by corn again. Manure is applied as far as available, either on the sod or after the first crop of corn. Other things equal, we have secured better crops of corn the second than the first year after grass. In cases where it has seemed best to grow a third crop of corn, some deterioration has been noticed. On experimental plats we have found it practicable to keep up a yield on land continuously cultivated in corn, but well manured each year with barnyard manure, equal to that when 9, grass and clover rotation is followed. The corn on the manured land has made a more vigorous and larger growth of stalks; and also has had many more weeds. WEIGHT AND SHRINKAGE OF CORN. The following tables give the actual and comparative weights of selected ears of corn of different dates, with weights of shelled corn and cobs in one set. The corn referred to in the first table was taken from the field before fully matured. It will be seen that there is a marked difference in the percentage of loss between the larger and the smaller varieties, and that there was a very noticeable loss during the week after gathering: hi 0 3 C D • K5* 3 C D C O £f 02 CD C D C3 K e+ 3 3 C D ^ CD J-r 1 Ul C D l-J <-*- tr" 05 C D & £ & CH £5 Or &w S3.

The ears in this trial were all better than the average of the crop as it came from the field, and were kept in separate lots, hung up in a barn, so that they lost moisture more readily than in the ordinary bin or crib. It should also be kept in mind that corn of these varieties in bulk would not have shown so large a percentage of shelled corn to total weight. ked •a .^ 1 21 IS 19% 20 14% 15% 18% 16 16 13 13 14 gP px ys gp Or 23.8 13.3 ^ 18.0 20.0 10.3 10.3 97
