BICE EXPERIMENTS IN CALIFORNIA. 
of Wataribune rice. The upper part of the leaves of red rice has a 
tendency to become yellowish when the plants are about 18 inches 
high. The red rice plants stool at an angle rather than upright, as in 
Wataribune. the head is more spreading, and the spikelets farther 
apart. Red rice shatters badly when mature. The grain resembles 
white rice, but when the husk is removed has a reddish seed coat 
which is objectionable to millers and consumers. The present infes- 
tations should be eradicated before the pest becomes well established. 
Italian red rice is spreading in the California rice fields. This red 
variety is not the same as the one described above. 
RED-STEM. 
Red-stem (Ammannia coccinea) is present in the rice fields to some 
extent. It grows in shallow ditches, in the rice fields, and in swampy 
places. It competes with the rice and in this way reduces yields. The 
plants have reddish stems at maturity. The red flowers are borne at 
the base of the leaves, and the seeds are contained in a capsule about 
the size of a small pea. These capsules are often present in threshed 
rice. Good cultivation should help in the control of this weed. 
CHEAT. 
Cheat (Bromus secalinus) grows on the California wheat lands. If 
rice is sown on poorly prepared wheat land there is danger of having 
considerable cheat in the threshed rice crop. The rice mills have 
trouble in separating the cheat from the rice and therefore can not 
pay as much for rice which contains cheat. It is not safe, therefore. 
to sow rice in wheat land without first killing the weeds and volunteer 
grain, because volunteer wheat, barley, and cheat are all objectionable 
in rice. 
OTHER CROPS FOR RICE LAND. 
On the limited land available at the Biggs Rice Field Station 
attempts have been made to find some crop that could be grown in 
rotation with rice. Beans, corn, grain sorghums, cotton, and hemp 
have been tested for this purpose. 
BEANS. 
Beans have not been grown successfully at Biggs. It is difficult to 
obtain good stands, and the soil is so heavy that cultivation after irri- 
gation is almost impossible. Insects are very troublesome during the 
early growth of the beans and in 1918 destroyed the crop before much 
growth had taken place. The soil at the station seems to be too 
heavy for successful bean culture. 
CORN. 
Corn has been grown at the Biggs Rice Field Station, but the results 
have not been satisfactory. Good stands have been obtained and 
the corn grew well and had a good color for about six weeks, but the 
plants then turned yellow and ceased growing. The unhealthy yellow 
color of the corn was undoubtedly due to poor drainage and the re- 
sulting high water table. The writer has observed that on the levees 
and high ground the growth of corn was more nearly normal and the 
plants retained a good healthy color. It is impossible to grow corn 
successfully on a heavy, poorly drained soil where the water table is
