Description Sorghum is an important cereal crop mostly grown for fodder and grain purpose across the tropical and subtropical region of India. Three Prosopis spp. namely Prosopis juliflora, Prosopis palida and Prosopis cineraria are well distributed and found in almost all states of India. The ground vegetation under Prosopis spp. canopy indicates that the spp. have some allelopathic chemicals which might reaches into soil system by either falling leaf or bark leachate or root exudates and consequently the releases allelochemicals into the soil. These chemicals inhibit the germination and establishment of understory crops. Therefore, a lab study was conducted to evaluate the allelopathic effects of 3 Propsis spp. on germination and seedling growth of sorghum (‘variety GJ-39’). The bark, leaves and soil samples of up to 10 cm depth near the trunk area of species were taken from different locations. The collected samples were grinded with the help of mortar & pastle and sieved. The sieved 15 g sample from each collection was taken and subsequently dissolved in 500 ml of water and used as treatments for the experiment. The treatments consisting of 3 Propsis spp. (bark, leaf and soil extract) and control with distilled water solution were used for the lab experiment in completely randomized design with three replications. The germination and seedling growth parameters were recorded at 4 and 7 days after sowing, respectively. Results indicated higher germination per cent 90 and 86 with control and Prosopis cineraria (leaf extract), respectively. However, highest (5.12 cm) and lowest (2.84 cm) radical length was recorded in Prosopis cineraria (leaf extract) and Prosopis Juliflora (soil extract), respectively. The Prosopis palida (bark extract) and (leaf extract) treatments was recorded highest fresh weight (3.1 gm) and plumule length (2.5 cm), respectively and was adjudged best over rest of the treatments with respect to fresh weight and plumule length.
