The present world is facing an acute shortage of biomass and developing countries require increase mass of firewood, fodder and fibres. In view of filling these requirements an increased investigation into fast growing, nitrogen fixing and fibre obtaining plant species has been required. Thus present study is an attempt to envisage the biomass productivity of Sesbania cannabina Poir. in different planting densities. Sesbania cannabina Poir. is a multipurpose leguminous crop with many unexplored economic uses. Environmental factors such as planting density greatly affect the biomass production of a plant species. Plant products such as leaves, fibres etc. are directly correlated with the biomass production of a plant species. Therefore it is important to study the effect of planting density on the biomass production of a plant. Planting densities affect various parameters of plants such as germination percentage, survival percentage, plant height, stem breadth, number of leaves, leaf length, pod length etc. Therefore present study is an attempt correlates the different planting densities with these morphological parameters. The present study was conducted at Department of Botany, University of Allahabad, India. The experiment was based on complete randomized block design with three replicates using five different planting densities viz. 1, 10, 25, 50 and 100. Means study showed that highest biological yield was achieved under plants within lowest density set. The results of this experiment showed that planting density is an important effective factor on quantity and morphological characteristics of plants that they can greatly affect yield of Sesbania cannabina Poir.
