Abstract
A field experiment was conducted in the Horticulture
farm of Sher-e-Bangla Agricultural University, Dhaka, during the period from
April 2012 to October 2012 to evaluate the influence of light intensity on
tomato yield. The experiment consisted of three levels of light intensity (viz.
L1: Full sunlight, L2: 20 % reduced sunlight and L3:
40% reduced sunlight. Significant variation was observed for the different
parameter of summer tomato with light intensity. Highest plant height (26.2 cm
at 60 DAT), leaf number (49.6 at 60 DAT), branch number (5.5/plant at 60 DAT),
number of flower (58.4/plant), number of fruit (39.5), length of fruit (4.8 cm),
diameter of fruit (4.5 cm), weight of individual fruit (40.9 g) and yield
(22.32 t/ha) of tomato was found from L2 which was statistically
similar to those of L3 the corresponding values were observed in L1
treatment.
Key
words: Lycopersicon
esculentum, light intensity and yield.
