Effect of Date of Planting.—Late-planted corn will usually reach thetasseling stage in a much shorter time than that which was planted a study of the averages given at the bottom of Table II it willbe seen that the ten varieties, results from which averages were taken,when planted during 1903, 1904 and 1906, at about the same date—the.

Dur-ing 1905 and 1907, with plantings made on May 19 and 14, respect-ively, the varieties prolonged their growth between planting and tassel-ing days beyond that required for the same development in number of days required to mature seems to be slightly decreasedby late planting. In 1905, as shown by the results in Table II, thelength of the period required to bring all the varieties to maturity wasshorter than in any of the other years used in the study. This seems to 22 N.
