Mariappan et al., 2013, Influence of Seed Fortification Treatment with Inorganic Nutrients in Jatropha Curcas (L.), Journal of Energy Bioscience, Vol.4, No.1 1-6 (doi: 10.5376/jeb.2013.04.0001)

Studies were conducted to evaluate the influence of seed fortification treatment with growth stimulants of inorganic nutrients viz., thiourea, KNO₃, K₂SO₄, KH₂PO₄, Na₂HPO₄, ZnSO₄, FeSO₄, MgSO₄, MnSO₄ and NaCl prepared in two concentrations viz., 0.5% and 1%. The seeds were removed at 16 h soaking duration and were sown in sand media under germination room condition (25℃, 95 ± 2% RH) and raised bed nursery along with water soaked and control seeds. The results revealed that among the inorganic nutrients K₂SO₄ at 0.5% concentration had better seed invigourative effect, which recorded 44 and 55 per cent than control in both controlled germination room and nursery bed respectively. However, shoot length, dry weight and fresh weight expressed a significant influence on seedling quality characters with the fortified seeds.
