^This field was badty infested Avith the Japanese ''nnt grass" {Cy- 

 perus rotiuidus) which formed a sod and nndonbtedly retarded the time 

 of maturing. 



-When this stand of corn was about 15 inches tall a three-daj^ strong 

 wind following a heavy rain nearly blew the corn out of the ground and 

 some never did recover, and after this wind all proved more susceptible 

 to hopper attacks than any other Cuban corn field we had. 



Cuban corn does not possess an absolute immunity to the leaf 

 hopper, but in most cases a marked resistance. Various soil 

 and weather conditions seem to greatly influence its ability to 

 withstand the leaf hopper. All our fields had leaf hoppers in 

 them, but in only a few cases did they seem materially to de- 

 crease the yield. There were occasional plants in all of our 

 Cuban corn fields which showed the stunted condition charac- 

 teristic of the varieties which were total failures, but these 

 stalks, except in the case of the field planted February 26, 1918, 

 were never abundant enough to seriously reduce the yield. 



Aside from this valuable apparent resistance to the hopper 

 the husks surround the ear so completely and tightly that there 

 never is any bird or weevil injury in the field even if it is not 

 harvested till long after it is matured. In a country where the 

 grain weevil is so common as in Hawaii this is an extremely val- 

 uable characteristic. With husks that open at the tip before 

 maturing it is a common experience to find ears that are rotten 

 with the larva stage of the weevil when harvested. 



Seed of this corn has been distributed by the college to 101 

 corn growers in every part of the Territory of Havvaii. Some 

 reported failures, others reported remarkable success ; most of 

 them failed to make any report. The following are a few com- 

 ments : 



"This is the best corn I have ever planted. It is weevil proof. 

 My corn is 7y^ to 8j/^ feet high." Lawrence Maioho, Koloa, 

 Kauai. 



Principal E. A. Brown of Puunene School, Puunene, Maui, 

 in reporting a yield of 31.5 bushels makes this comment: "Kula 

 corn planted about the same time was a total failure. It took 

 on a streaked appearance when about half grown and failed 

 to make further development. Planted in December it did 

 very well."
