Abstract:
The present investigation entitled “Influence of seed invigouration treatments on seed quality parameters of soybean [Glycine max (L) Merill] was carried out in kharif 2020 at the Seed Testing Laboratory, Department of Seed Science and Technology, College of Agriculture, Junagadh Agricultural University, Junagadh. The seeds of two soybean varieties (V₁: GJS 3 and V₂: JS 335) were treated/coated with different seed invigouration treatments (S₁: Control, S₂: Hydration-dehydration treatment with distilled water for 8hrs, S₃: 1.5% CaCl₂ for 8 hrs. (15 ml/l), S₄: 2.0% KH₂PO₄ for 8 hrs. (20 ml/l), S₅: 1.0% KNO₃ for 8 hrs. (10 ml/l), S₆: 10% PEG 6000 for 8 hrs. (100 ml/l), S₇: 10% Rhizobium japonicum culture for 8 hrs. (100 ml/l), S₈: Seed coating with sweet flag rhizome powder @ 5 g/kg seed, S₉: Seed coating with cytozyme SDM powder @ 3 g/kg seed and S₁₀: Seed coating with neem kernel powder @ 5 g/kg seed) repeated thrice and evaluated for seed quality parameters viz., germination percentage, seedling length (cm), seedling dry weight (mg), seedling vigour index - I and seedling vigour index – II using Completely Randomized Design (Factorial) as per the method suggested by Cochran and Cox (1957). Among the varieties, JS 335 and among the seed invigouration treatments, seed coating with sweet flag rhizome powder @ 5g/kg seed recorded the maximum germination percentage, seedling length, seedling dry weight, seedling vigour index I and seedling vigour index II.
