Bahtim Experiment Station, Cairo; U. A. R.
Plots were replicated 4 times at Bahtim, and yield was obtained for the October 30, November 19, December 9, and December 29 plantings. In these plantings, there was no damage by birds and also plant stand was almost complete. Yield of seed at the end of the season was weighed and results were analyzed statistically; average yield from the 4 replicates given in the accompanying table.
Yield of seed for each date of planting was singly analyzed, and statistical analyses showed that differences between varieties were statistically significant only in the case of the October 30 planting. Least significant differences were 0.316 Kg and 0.430 Kg at 0.05 and 0.01, respectively. Combined analyses between the 4 dates of planting showed that differences between varieties and between dates of planting were highly significant. Interaction between varieties and dates of plantings were not statistically significant. Least significant differences in case of varieties were 0.180 Kg and 0.239 Kg at 0.05 and 0.01, respectively and 0.128 Kg and 0.170 Kg at 0.05 and 0.01, respectively, in case of planting dates.
