Sumario: | A field experiment was conducted on the experimental
farm of the University of California at Davis to determine
the effect of three planting dates and four seeding rates on
the production of on of three commonly grown
cultivars (Allium cepa L „). This experiment was part of a
project to determine optimum planting date and plant
population.
The cultivars were: Texas Grano, an early short - day
cultivar; California Red, asemi early intermediate - day
cultivar; and Sweet Spanish, a late long - day cultivar. They
were planted on March 5, March 23, and on April 12„ For each
planting date the f o l l o w i n g seeding rates were used; 19, 31,
43 and 56 kg/ha. The first planting date, however, was not
included in the statistical analysis, due to its low plant
population. |
