Abstract:
In agroforestry system, light is a limiting factor for maximum crop production.
Therefore, a pot experiment was conducted in the Field Laboratory of the Department
of Agroforestry and Environmental Science, Sher-e-Bangla Agricultural University,
Dhaka- 1207, during the months of October 2020 to March 2021 with three cauliflower
varieties viz. V
1
(Chandi), V
2
(Snow White), V
3
(Indian Crown) under four shade
treatments/light intensities, [100%, 75%, 50% and 25% light intensity which indicate
control (S
0
), S
1
, S
2
and S
3
, respectively] to evaluate their morpho-physiological and
growth performances. Low light stress [mainly 50% light intensity (S
2
) and 25% light
intensity (S
3
)] substantially reduced the germination rate, plant height, plant weight
(fresh and dry weight), leaves number, leaf length, leaf width, flowering dates, stem
diameter, photosynthetic performance (SPAD value) of different cauliflower varieties.
However, considering the obtained findings Snow white variety showed less negative
performance than the other varieties under shaded condition. So, among the tested
cauliflower varieties Snow white might be suitable for shaded condition with low light
intensities.
