Abstract

Dragon fruit has become a promising high-value crop in India but has not so much awareness about its production technology. The present investigation was planned to evaluate the effect of some chemical and growth regulator applications on the growth of dragon fruit. The investigation had 9 treatments (T1 control, T2 - KNO3 @ 3 %, T3 - KNO3 @ 4 %, T4 - GA3 @ 50 ppm, T5 -GA3 @ 100 ppm, T6 - KNO3 @ 3% + GA3 @ 50 ppm, T7 - KNO3 @ 3 % + GA3 @ 100 ppm, T8 - KNO3 @ 4 % + GA3 @ 50 ppm, T9 - KNO3 @ 4 % + GA3 @ 100 ppm) with three replications laid out in Randomized Block Design. Different concentrations of GA3 and KNO3 were found to have a significant impact on the vegetative growth variables of dragon fruit plants. As a result, the present investigation found that combining the effect of GA3 and KNO3 in the form of treatment T7, i.e. KNO3@3% + GA3@100 ppm would be most effective for better vegetative growth such as average increase plant height (10.33cm), distance between areoles (0.21), the arch height (0.6mm), increased number of spines per areole (6.0) and growth of newly emerged shoots (26.6) of dragon fruit plant or in Northern India climatic conditions. Hence, the application of KNO3@3% + GA3 @100 ppm could be used for better plant growth and development of the dragon fruit.

Conclusion

As a result, the present investigation found that combining the effect of GA3 and KNO3 in the form of treatment T7, i.e. KNO3@3% + GA3@100 ppm would be most effective for better vegetative growth such as an average increase in plant height (10.33cm), distance between areoles (0.21), the arch height (0.6mm), increased number of spines per areole (6.0) and growth of newly emerged shoots (26.6) of dragon fruit plant or in Northern India climatic conditions.
