The results showed that all seed priming treatments were found effective in enhancing the germination percentage as compared to hydro (unsoaked) priming. However, among them, the T6 i.e. priming with 1ppm neem extract showed a maximum seed germination percentage of 90% (Table 3). T1, T3, T5, T2, T4, T7 increased germination percentage but were non-significant among themselves (LSD=16.49).

T1 i.e. hydropriming (12 hours soaked) showed a greater influence on seed vigor as compared to other priming techniques. The maximum (533) and the minimum (337.7) seed vigor index was recorded in the treatment T1 i.e. hydropriming (pre-soaked) and T2 i.e. halopriming respectively. Following treatment T1, subsequent treatments that presented greater seed vigor index was T6 (520), T4 (505), T3 (460), T5 (435), T7 (421), T8 (339.9) respectively.
