Abstract
An experiment was carried out to evaluate the effect of growth regulators viz., Gibberellin (GA3), lemon juice and tamarind leaf extract on germination and vigor of lentil seeds. The experiment was conducted with BARI Masur-4 cultivar, and three growth regulators: gibberellin, lemon juice and tamarind leaf extract were used. Three concentrations of gibberellins (10, 20 and 30 ppm), three concentrations of lemon juice (2, 4 and 6 %) and three concentrations of tamarind leaf extract (0.05, 0.1 and 0.15%) with two soaking time duration: 6 and 12 hours and control were used. Gibberellin (GA3) improved germination percentage, seedlings length, dry matter, germination index and vigor index of lentil. Lemon juice enhanced germination percentage, seedling length, vigor index and germination index in lentil. Tamarind leaf extract increased the germination percentage, vigor index and speed of germination in lentil. In comparison with plant growth regulators, length and weight was found to be positively correlated and in most cases relationships were significant.
