Abstract

The laboratory experiment was conducted during summer 2022 to study the “effect of seed priming on germination and seedling growth of sesame”. The different 20 seed priming treatments comprising of T1: Without any treatment (control), T2: Hydro priming (with water), T3: Salicylic acid @ 1 %, T4: NaCl2 @ 2 %, T5: PEG @ 5 %, T6: Na2PO4 @ 2.0 %, T7: GA3 @ 100 ppm, T8: KCl @ 2 %, T9: KNO3 @ 2.0 %, T10: KH2PO4 @ 2.0 %, T11: Humic acid @ 1.5 %, T12: Vermiwash @ 5 %, T13: Coconut water @ 5 %, T14: Trichoderma viride 0.25 g/100 ml, T15: Neem leaf extract 5 g/100 ml, T16: Cow urine @ 5%, T17: Jivamrut @ 5%, T18: Bijamurt @ 5%, T19: Tulasi leaf extract @ 5% and T20: Moringa leaf extract @ 5% were given to seeds of sesame variety GJT 5. The observations on germination (%), shoot length (cm), root length (cm), seedling length (cm), seedling dry weight (mg), seedling vigour Index I and seedling vigour Index II were recorded. Among seed priming treatments, significantly the maximum germination (88.00 %), shoot length (5.50 cm), root length (2.93 cm), seedling length (8.43 cm), seedling dry weight (48.09 mg), seedling vigour index I (741.33) and seedling vigour index II (4233.54) was recorded in seeds primed with 5 per cent coconut water (T13), The next best treatment with respect to all these traits was seeds primed with 5 per cent vermiwash (T12). Significantly the lower germination (78.75 %), shoot length (3.55 cm), root length (2.45 cm), seedling length (6.00 cm), seedling dry weight (38.89 mg), seedling vigour index I (472.43) and seedling vigour index II (3062.16) was recorded in control (T1).

Conclusion

Among seed priming treatments, seeds priming with 5 % coconut water (T13) was recorded the maximum germination, shoot length, root length, seedling length, seedling dry weight, seedling vigor index I and seedling vigor index II. Coconut water (coconut liquid endosperm), with its many applications, is nutritious and beneficial for health. Some of the most significant and useful components in coconut water are cytokinins, (e.g., kinetin and trans-zeatin) which are a class of phytohormones, indole-3-acetic acid (IAA), the primary auxin in plants and other components like sugars, sugar alcohols, lipids, amino acids, nitrogenous compounds, organic acids and enzymes, and they play different functional roles in plant and human systems due to their distinct chemical properties. The seeds primed with 5 per cent coconut water resulted into higher germination with good vigour in sesame.
