WORK OF YUMA EXPERIMENT FARM IN 1912. 25 



MISCELLANEOUS CROPS. 



In 1912 half an acre was planted to liemp in order to determine the 

 possibilities for hempseed production on the irrigated lands of the 

 Southwest. The soil was lacking in uniformity. On the spots of 

 medium and heavy soils the hemp attained a height of 10 to 20 feet 

 and seeded abundantly. The seed was harvested, but at the time 

 of writing it had not been sufficiently cleaned to give 3deld-test weights. 



On account of the rapidity of growth of bamboo and the mnumer- 

 able uses to which it can be put, several hundred plants of two large 

 commercial species from the Orient were planted m nursery rows in 

 1911. These species have not proved hardy enough to withstand 

 the low temperatures which occasionally occur. However, it is pos- 

 sible that after the plants become well established they will be suffi- 

 ciently self-protectmg to pass through most winters without injury. 

 The bamboo work was extended in 1912 by a half-acre planting on 

 low land in order to determine the adaptability of bamboo to land 

 havmg a high underground water table. 



The carob {Ceratonia siliqua), a promising mtroduction from Spain, 

 is being tested. The plants were frozen to the ground in the winter 

 of 1911-12, but they put out branches from below the ground line 

 and made a good growth during the past summer.
