Abstract:
The experiment was conducted during two consecutive years 2019-20 & 2020-21 at Oil Seed Farm of C. S. Azad University of Agriculture & Technology Kanpur. Two varieties namely Kanti (V₁) and Maya (V₂) seeds were sown in Rabi season (October-April 2019 & 2020), seven chemicals concentrations were applied as foliar spray treatments at vegetative stage, at anthesis stage and at both stage which were as Salicylic acid @ 800 ppm (T₁, T₈ and T₁₅), Salicylic acid spray at vegetative stage @ 400 ppm (T₂, T₉ and T₁₆), Ascorbic acid @ 10 ppm (T₃, T₁₀ and T₁₇), Potassium chloride @ 1% (T₄, T₁₁ and T₁₈), thiourea @ 400 ppm (T₅, T₁₂ and T₁₉), Cycocel @ 800 ppm (T₆, T₁₃ and T₂₀), Cycocel @ 400 ppm (T₇, T₁₄ and T₂₁) and T₀-Control (without spray). Freshly harvested seeds of each plot were stored under ambient condition in cotton bag for nine months and seed viability (%), seed germination (%), seedling length (cm) and seedling vigour index-I was recorded at every three month of interval. At the end of storage period significantly maximum seed viability (90.42%), seed germination (89.05%), seedling length (14.24cm) and SVI-I (1268) was found in sample collected from treatment T₁₉-Thiourea spray at vegetative + anthesis stage @ 400 ppm followed by treatment T₁₆ irrespective of varieties. Within varieties, variety Maya was significantly superior over variety Kanti.
