Dear Dr. Lamm:
An M.S. student of mine conducted a study in 1996 in Baton Rouge using the
North Carolina Design II. His results have recently been published in Field
Crops Research 61:211-222 (1999). Data presented in Table 1 show values for
kernel-fill rate/day ranging from 8.32 mg to 11.21 g with an LSD (0.05) =
0.24. Hope this information is helpful.
