Abstract	SUMMARY A laboratory experiment was carried out at Seed Quality and Research Laboratory, National Seed Unit, University of Agricultural Sciences, Dharwad during the Rabi-Summer, 2010-11. The experiment consisted of 8 treatment combinations involving two insect attractants, A 1 - Jaggery solution @ 2% and A 2 - Commercial attractant (Bee-Q @ 0.175%), two micronutrients M 1 - Boron @ 0.8% and M 2 - Molybdenum @ 0.05% and two growth regulators. G 1 - Gibberilic Acid (GA 3 ) @ 50 ppm and G 2 - Naphthalene Acetic Acid (NAA) @ 50 ppm. Among the insect attractants sprayed, Bee-Q recorded significantly higher test weight (2.62 g), germination percentage (91.16) and vigour index (1373) sprayed at the time of 50 per cent flowering stage and also showed lower electrical conductivity (0.264 dSm -1 ). Among the growth regulators sprayed, GA 3 (Gibberilic Acid) @ 50 ppm sprayed showed significantly higher test weight (2.60), germination percentage (92.66) and vigour index (1426) and also recorded lower EC (0.260 dS/m). Application of Molybdenum @ 0.05 per cent as foliar spray recorded significantly higher test weight (2.50 g), germination percentage (90.58) and vigour index (1332) and also recorded lower EC (0.278 dS/m). The interaction effects between insect attractants, micronutrients and growth regulators were found significant. The treatment combination of A 1 M 1 G 2 found significantly superior for seed quality parameters over all other treatment combinations.
