EFFECT OF ORGANIC AND INORGANIC GROWTH REGULATORS ON GERMINATION AND VIGOUR OF CHICKPEA SEED

The pot experiments were carried out on chickpea in Rabi season during 2012 to 2013. The experiments were conducted to evaluate the effect of GA₃, lemon juice and tamarind leaf extract on germination and vigor of chickpea seed. The experiments were done with cultivar, BARI Chola-6 with three growth regulators: gibberellin, lemon juice and tamarind leaf extract. During Rabi season 2012 to 2013; three concentrations of gibberellins (10, 20 and 30 ppm), three concentrations of lemon juice (2, 4 and 6 %), three concentrations of tamarind leaf extract (0.05%, 0.1% and 0.15%) with two soaking time duration: 6 hours and 12 hours with control. Gibberellin (GA₃) with 6 hours improves germination percentage, seedlings length, dry matter, germination index and vigor index of chickpea.
