 ABSTRACT

The present investigation was carried out at orchidorium, Regional Horticultural Research and Extension Centre, University of Horticultural Sciences campus, GKVK, Bengaluru during September 2015 to June 2017. The results indicated a significant influence of the treatments on different vegetative and yield parameters. Plant height was recorded maximum in treatment NPK @ 2:6:2 (T9) followed by 2:6:1 (T8) (44.08 cm and 44.08 cm respectively) and lowest (30.42 cm) was observed in control (T1), higher numberof shoots per plant were registered in treatment NPK @ 2:6:2 (T9) (4.73) and lower number of shoots produced per plant was noticed in control (3.40). Maximum number of leaves per plant was produced in NPK levels 2:6:2 (7.73) and 2:6:1 (7.47). However, control (5.73) recorded minimum number of leaves per plant. Higher number of pseudo bulbs per plant was recorded in 2:6:2 NPK level (T9) (4.63) and lowest was recorded in (T1) control (3.82). Maximum leaf area (59.21 cm2) was observed in NPK level 2:6:2 (T9) and control recorded minimum leaf area of plant (34.28 cm2). Significantly higher number of spikes per plant, spikes per square meter and per hectare was registered in treatment (T9) 2:6:2 NPK level (2.80, 70.00 and 5.60 lakh) followed by treatment T8 (2:6:1) and lowest was noticed in control at 21 MAT respectively months after treatment. Highest cumulative yield per plant, per square meter and per hectare was noticed in treatment 2:6:2 (T9) (17.13, 428.00 and 34.27 lakh respectively) and it was on par with 2:6:1 (T8) (16.27, 406.67 and 32.53 lakh respectively) and lowest cumulative spike yield was observed in (T1) control (9.20, 230.00 and 18.39 lakh respectively).

Key words: Foliar nutrient, Dendrobium.
