A Field Trial of Certain Sugar Cane Varieties: Series B

The present series was planted in October, 1928, and comprises those varieties of which it was considered desirable to have quantitative trials and of which sufficient material had already accumulated for this purpose. These varieties were Co 205 and 210 of the Coimbatore seedlings, several, canes of the Uba type, including CH. 64/21, a cross between Uba and D. 74, produced at the Cuban Agricultural Experiment Station near Havana-Kavangire, an oldestablished cane that has often been confused with Uba in different parts of the world-Agaul, a cane imported from India by the Department of Agriculture some years ago, and Merthi, another Indian cane'imported by us via the U.S. Bureau of Plant Industry at Washington; also Oshima, a cane of Japanese (Formosan) origin that had also come to us via Washington. . Another cane of the Uba type is Cuban Selection, an. unidentified variety introduced unofficially into this country some years ago from Cuba. P.O.]. 213 was included, which is also a thin type of cane and was produced at the J avan Experiment Station some years ago, and also Townsend's Selection, a variety of cane that had long been growing on the estate of A. Townsend at Umhlali and known by him as " China" cane. There was also' Sc. 12/4, a thick cane from the West Indies; P.O.]. 2714 was also originally included, but it was found necessary eventually to ' use all the material of this variety for further replanting so that it did not come into the final results. P.O.J. 2714, however, is included with other varieties of this type in later series of trials (Series D. and E.). The site selected for the experirnent was a rather heavy clay loam on a gentle slope facing West, gradually merging into a level patch at the bottom. The soil was of fair depth and was apparently
