Abstract

A field experiment was carried out during 2020-2021 at Horticulture Research Farm, SHUATS, Prayagraj and the aim of investigation was to determine the effect of foliar application of brassinosteriods and salicylic acid on vegetative growth of Nagpur Orange. This experiment was conducted in Randomized Block Design (RBD) with nine treatments viz. T0 Control, T1 Brassinosteriod @ 0.5ppm, T2 Brassinosteriod @ 1.0ppm, T3 Brassinosteriod @ 1.5ppm, T4 Brassinosteriod @ 2ppm, T5 Salicylic acid @ 50ppm, T6 Salicylic acid @ 100ppm, T7 Salicylic acid @ 150ppm and T8 Salicylic acid @ 200ppm were applied during the research work on Nagpur Orange. The treatment was done at vegetative growth stage at 30, 60, 90, 120, 150 and 180 DAT was calculated in each treatments which were selected in each plant. Spray of T4 Brassinosteriod @ 2ppm resulted in highest survival percentage and vegetative growth parameters like survival percentage (100% ), Mortality percentage (0.00%), plant height (69.60cm),

Keywords

Conclusion

Thus, it can be concluded from the findings of the present investigation that foliar application of T4 Brassinosteriod @ 2ppm resulted in highest survival percentage and vegetative growth parameters like survival percentage (100%), Mortality percentage (0.00%), plant height (69.60cm), number of leaves per plant (129.24), number of branches per plant (17.75), stem girth (3.37cm), plant spread (67.19), leaf area (13.98cm2) and Chlorophyll SPAD (75.06). Therefore, application of Brassinosteriod @ 2ppm will improve vegetative growth of newly planted Nagpur Orange plants and the growers will be economically benefited
