Abstract:
The present investigation entitled “Standardization of optimum sowing time and protocols on seed germination and survival percentage of swallow root (Decalepis hamiltonii wight & Arn)” was carried out at Department of Plantation, Spices, Medicinal and Aromatic crops, Dr. YSRHU-College of Horticulture, Anantharajupeta, Annamayya District, Andhra Pradesh during 2022-2023. The seeds were sown in raised beds and polybags in September 2022, March and April, 2023 after subjecting to different seed treatments. From the experiment, it was revealed that seeds sown in the month of march + raised beds + pre seed treatment with H₂O₂ @ 0.3% for 8 hours had early germination and seeds sown in the month of march + raised beds + pre seed treatment with H₂SO₄ @ 0.3% for 10 minutes had superior performance on germination percentage whereas seeds sown in the month of march + Polybags + H₂O₂ @ 0.3% for 8 hours had superior performance on survival percentage.
