The morphological response of the soybean growth (Glycine max (l)) until vegetative stage 3 on various intensities of light

Abstract

This study aims to determine the effect on various intensity of light on the response of vegetative growth of local soybean to vegetative three stadia. Greenhouse experiments with 15 experimental units were prepared in a completely randomized design with treatments consisting of: without shade, 50, 60, 70, and 80% shade. The observed variables are plant height, number of leaves, number of branches, and stem diameter, root length, wet weight, and dry weight of stove. All data were analyzed by variance followed by All data were analyzed by variance followed by LSD test at 5%. The results showed that shading percentage had an effect on plant response on all growth variables until the end of vegetative-3 stage. The higher the shade percentage, the more increase the growth of plant height and root length, but on the contrary decrease the growth of the number of leaves, in effect on the decrease of leaf number, branch number, stem diameter, and wet weight and dry weight of plant.
