| dc.description.abstract | A field experiment was carried out at the Research Field of
Department of Crop Physiology and Ecology, Hajee Mohammad
Danesh Science and Technology University, Dinajpur during the
period from April 20, 2015 to June 30, 2015 to evaluate the three
mungbean varieties in regard to morpho-physiological parameters,
yield and yield contributing characteristics under different light
levels. The experiment was laid out in a split plot design with three
replications. Three light levels i.e. 100, 75 and 50 percent of full
sunlight were assigned in the main plot while three mungbean
varieties (BINA mung 5, BINA mung 8 and BARI mung 6) were
assigned in the sub-plot. Light levels were adjust using mosquito nets
of different mesh sizes and color. Different light levels had a
significant effect on morpho-physiological characteristics like plant
height, number of leaves, leaf area, chlorophyll content, dry weight of
leaf, stem and root of different days after sowing (DAS) of different
mungbean varieties. In case of yield and yield contributing
characteristics like number of pods per plant, number of seeds per
pod, thousand grain weight and yield of different mungbean varieties
found higher at 100 percent of full sunlight compare to 75 and 50
percent of full sunlight. Among the three varieties, BARI Mung 6
showed lesser reduction in pods per plant, number of seed per pod,
thousand grain weight and yield both at 75 and 50 percent of full
sunlight and this variety may be used as tolerant variety under partial
shade condition. | en_US |
