Abstract: Present investigation was undertaken to see the effect of different plant hormones like GA₃ and ABA on germination and other seedling characters of cultivars of oil seed and pulses. Seed treatment with GA₃ and ABA at the concentration 10^-3 M was provided for 2 hours. After that treated and control seeds were placed in square glass plate with three replications and placed inside germinator. After germination in case of oil seed, Jhumka (V₁) recorded the highest germination percentage (94.11%) for T₁ followed by T₂ and lowest germination percentage (91.87%) was recorded for control. For the variety Bhagirathi (V₂) a slight decrease in germination was recorded in case of T₂ than control, whereas, T₁ recorded the highest of it (97.26%). For pulses, Goutom (V₃) recorded highest value of germination percentage for T₁ and lowest value for the T₂. For V₄, T₀ was found with highest germination percentage followed by T₂ and T₁. Seedling shoot length (cm) of V₁ was the highest in case of T₁ followed by T₀ and slight decrease was noticed for T₂ where the value was 8.95 cm. In case of V₂, highest seedling shoot length was noticed for T₁ and lowest (7.91 cm) for T₀. For V₃, T₁ was observed with highest value followed by T₀ whereas T₂ recoded lowest value. In case of V₄, it obtained the highest seedling shoot length (12.74 cm) for T₁ and the lowest (9.10 cm) for T₀. Seed treatment with ABA though recorded small increase in some of the seed and seedling parameters but it cannot be recommended for seed treatment of different cultivars or varieties of oil seed and pulses. Seed treatment with GA₃ in most of the cases both for oil seed and pulses enhanced characters like germination percentage, seedling length, vigour index etc. than control, indicating use of GA₃ for better performance of oil seed and pulses. So, seed treatment with GA₃ at the concentration of 10^-3 M can be recommended to farmers for better seedling growth in case of pulses and oil seeds.
