Description The field experiment was conducted during Rabi season of 2010-11 at the Main
Agricultural Research Station, University of Agriculture Sciences, Dharwad. The
experiment consisted of eight treatment combinations involving two insect attractants,
viz., Jaggery solution @ 2% (A1), Commercial attractant (Bee-Q @ 0.175%) (A2),
Two micronutrients (M) viz., Boron @ 0.8% (M1), Molybdenum @ 0.05% (M2) and
Two growth regulators (G) viz., Gibberellic acid (GA3) @ 50 ppm (G1), Naphthalene
Acetic Acid (NAA) @ 50 ppm (G2). The results indicated that and it was laid out in
RBD with factorial concept. Among the insect attractants sprayed, Bee-Q recorded
significantly higher plant height (87.37 cm) compared to Jaggery solution (82.29cm).
Application of Boron @ of 0.8 per cent as a foliar spray recorded significantly higher
plant height (84.98 cm) compared to the Molybdenum at the rate of 0.05 per cent
application. Among the growth regulators used Gibberellic acid @ 50 ppm sprayed at
the time of 50% flowering showed significantly higher plant height than the
Naphthalene acetic acid @ 50 ppm. The interaction effect between insect attractants,
micronutrients and growth regulators exhibited significant variation on pod set per
cent. The treatment combination of A1M1G1 (Jaggery solution + Boron + GA3) found
significantly superior over all other treatment combinations. Significantly higher seed
yield per ha (268 kg) was noticed with foliar application of Bee-Q when compared to
Jaggery solution (227 kg) with the extent of 18% of increase. Plots sprayed with
Boron recorded maximum seed yield compared to the Molybdenum spray. Among the
growth regulators, GA3 @ 50 ppm recorded maximum seed yield when the crop was
sprayed at 50 per cent flowering stage. Among the insect attractants sprayed, Bee-Q
recorded significantly higher test weight (2.62 g), germination percentage (91.16)
compared to Jaggery solution.
