3.2. Seed length
The effects of companion crops and sowing date on seed length
were significant. However, interaction of companion
crops · sowing date had no significant effect on seed length
(Table 1). The highest and the lowest seed lengths were recorded
for corn–clover and corn–dill, respectively (Table 2).
Seed length of corn plants which were grown under T1 was
considerably higher than that under delayed planting of cover
crops (Table 2). Delayed flowering, reduction of leaves number
and plant length and deduction of flowering period due to
weed-infested treatments resulted in 100 seeds weight and seed
size deduction. (Noormohammadi and Siyadat, 2001).
