Abstract
The present investigation entitled “Effect of Pre-sowing Treatments on Germination and Growth of Diospyros lotus Linn.”was carried out in the Division of Agroforestry, Sher-e-Kashmir University of Agricultural Sciences & Technology, Jammu, Chatha, in the year 2022. The experiment was laid out in complete randomized design (CRD factorial) with three replications. D. lotusseeds were subjected to nine pre-sowing treatments (T₁- soaking in cold water for 48 hours; T₂-soaking in cold water for 72 hours; T₃-cow dung slurry for 1 week; T₄ - cow dung slurry for 2 weeks; T₅- mechanical scarification; T₆- concentrated H2SO4 for 2 minutes; T₇- concentrated H2SO4 for 4 minutes; T₈ - concentrated H2SO4 for 6 minutes; T₉ -control (No treatment) and the pre-treated seeds were sown in four potting media M₁- (soil only); M₂- soil: sand (1:1); M₃- soil: sand: FYM (1:1:1); M₄- soil: sand: vermicompost (1:1:1). Various parameters studied weregermination percentage, number of leaves, number of secondary roots, length of primary root, seedling height, collar diameter, fresh shoot weight, fresh root weight, total seedling fresh weight, dry shoot weight, dry root weight, total seedling dry weight, seedling quality index, coefficient of velocity of germination,germination rate index, sturdiness quotient, root: shoot ratio and mean germination time. The results show that out of the nine pre-sowing treatments, treatment T3 (treating the seeds with cow dung slurry for 1 week) was found to be the best whereas, in case of potting media, media M3 (soil: sand: FYM-1:1:1) was the best for most of the growth parameters. Overall, the best combination of the pre-sowing treatment and potting media was found to be T3M3(cow dung slurry for 1 week in soil: sand: FYM-1:1:1) where highest values were recorded for most of the growth parameters.It can be concluded from the present study that seeds of Diospyros lotustreated with cow dung slurry for 1 week and sown in media containing soil: sand: FYM in 1:1:1 ratio shouldbe preferred to obtain better quality seedlings.
