(Forestory), DEPARTMENT OF FOREST BIOLOGY AND TREE IMPROVEMENT COLLEGE OF FORESTRY BANDA- 210001, UTTAR PRADESH, INDIAhttps://krishikosh.egranth.ac.in/handle/1/5810206081Sandalwood (Santalum album L.) is indigenous to India and belongs to the family Santalaceae. The Santalum species generally raised for large scale commercial plantation as well as for the forest. The main source of raising Santalum seedling its seed which difficult to germinate and required different pre-sowing treatments, Sandalwood seeds are impermeable to water causes poor germination. Sandalwood is recognized as hemi-root parasite and 70% of seedling are able to established haustoria with suitable host in the early days of emergence, seed pre-sowing treatments and combination with host plants have a significant impact on germination and seedling growth therefore, Experiment was conducted in the departmental nursery of college of forestry in 2022-23 at Banda district ,Seeds were collected from the Shivmogga forest division, Karnataka and treated with the different treatments which includes plant growth regulators such as –GA3(500, 1000 ,15000 ppm ), Kinetin(40,60 ppm), NAA(400 ppm), Cow urine (1:1), Cow dung slurry(1:1), Concentrated H2SO4 (2%,3%), And Hot water (60 minute). Among all the treatments seeds treated with GA3 -1500 ppm recorded maximum germination percentage (43.667), Followed by GA3 1000 ppm as compared to others treatments use during the experiment , In other experiment primary plant host relationship was studied with Cajanus cajan, Mentha arvensis, Ocimum sanctum, Alternanthera ficoidea (Green), Alternanthera ficoidea (Red) , Clerodendrum inerme L, Among all the combinations the maximum growth was found with the Cajanus cajan (Arhar) 300.22mm ,The effect of pot mixture also studied during the experiment and maximum growth was found with the following Soil + Sand + Vermicompost (2:1:1) , Soil +Sand + Vermicompost ((1:2:1), Red soil +Sand +Vermicompost (2:1:1), Soil + Sand +FYM (1:1:1), Soil + Sand + FYM (2:1:1).EnglishThesis
