Abstract

The present investigation was carried out to assess the effect of plant growth regulator on flowering and fruit yield attributes of Papaya plant Pusa dwarf (Carica papaya) during 2017-18 at Experimental Farm of Horticulture field of Uttar Banga Krishi Viswavidyalya, Cooch Behar. The experiment was laid out in the Randomized Blocked Design (RBD) with fourteen treatment combinations replicated thrice. The observation was recorded during the trial experiment on the Number of flowering, percentage of the male and female flower, days required from flowering to maturity, number of fruit bear in a plant, the weight of the fruits, percentage of fruit set, bearing height of first fruit, and yield. Pusa dwarf being an outsource cultivar, its hardening stage was regularly mandated for about 2 weeks until it was fully established. The study indicates that the growth, yield, and quality of papaya fruits were significantly influenced by plant growth regulators. The treatments considered we

Keywords

NAA (Naphthalene acetic acid), TIBA (Triiodobenzoic Acid), GA3 (Gibberellic acid), Brassinosteroids (BRs), Parts per million, foliar application, sex development; flower.

Conclusion

From this experiment, we can conclude that the application of “Brs” has more positive effect on flowering and the yield attributes than TIBA, NAA and GA3. This was due to the physiological effect of brass inosteroids on flowering and fruit yield of the plant as a result of cell elongation and cell division. An increase in photosynthetic activity, better food accumulation, and an increase in the flowering parts especially the female part were due to the action of brass inosteroids.
