Abstract

Drumstick (Moringa oleifera) is belongs to the family Moringaceae, The leaves, pods, flowers and immature pods of this tree has enormous nutrients and because of these high nutritive values it is used as vegetable in many countries. The present investigation was carried out to find out the response of foliar application of plant growth regulators and micronutrients on growth, flowering, fruit set and yield parameters of drumstick cv. Bhagya in a randomized block design, twenty treatments with two replication during rabi - summer 2021-22 at Department of Vegetable Science, Kittur Rani Channamma College of Horticulture, Aabhavi, Karnataka, India. The experimental results revealed that all treatments performed significantly better when compared to control with respect to all morphological and yield attributes. The maximum number of primary branches (6.90), length of primary leaf rachis (50.99 cm & 67.19 cm at 30 & 60 DAS), number of flowers per panicle (40.00), number of panicles per plant (72.50), number of pods per panicle (2.50), fruit set (6.25%), number of pods per plant (171.25), individual pod weight (54.30 g), individual pod girth (4.93 cm), yield per plant (9.30 kg) and highest benefit cost ratio (3.43) were recorded in NAA @ 40 ppm + Zinc Sulphate @ 0.5 per cent + Boric Acid @ 0.2 per cent.. However, maximum plant height (2.80 m & 4.09 m at 30 & 60 DAS) and individual pod length (66.24 cm) was recorded in GA3 at 20 ppm.

Conclusion

In the nutrient management of drumstick cv. Bhagya was found that, the foliar application of NAA at 40 ppm + Zinc Sulphate at 0.50 per cent + Boric Acid at 0.20 per cent effectively increased the growth, flowering, fruit set and yield with maximum benefit cost ratio than control (water spray).
