A field trial was conducted to regulate flowering in pineapple cv. Kew by application of fertilizer, mulching and flowering hormone together to achieve maximum flowering and yield at ICAR–RCER, Ranchi Centre, India. The study was carried out infactorial RBD experimental design with three replications. All samples were analyzed through standard methods. Studies showed that in treatment T6 involving F2 fertilizer dose for pineapple (100 per cent N: P:K= 600:400:400 kg/ha), plastic mulching and ethephon 30 ppm together, the final flowering per cent of pineapple were 70.42 and 69.11 during first and second year. The pineapple cv. Kew recorded the maximum average TSS of 14.85 0B under plastic mulch along with F2 fertilizer treatment in T6. The highest average yield of pineapple was observed in F3 ( 100% standard fertilizer dose of pineapple + 50 % standard fertilizer dose of guava) and local weed mulching with ethephon 30 ppm treatment (T8) and average yield was 8.9 t/ha as intercrop (TSS=13.90B). However, under T8 treatment, mulching material when changed from plastic to local weed, the average yield of both the years was increased from 7.95 to 8.9 t/ha. On the contrary, the average TSS of the fruits decreased from 14.850B to 13.90B. In T8, F3 treatment with local weed mulching also recorded the maximum average soil moisture was 20.94% during growing period which influenced the production of bigger fruit (1.41 kg) by affecting growth process. Regulated deficient irrigation under hill and plateau condition of India gave the promising results which paved the way for cultivation of pineapple with 100% standard dose of N: P: K fertilizer (600:400:400 kg/ha). T6 treatment, i.e., F2 fertilizer dose, plastic mulching and ethephon (30 ppm) may be recommended for obtaining quality fruit (TSS=14.850B). On the other hand, T8, i.e., F3 fertilizer treatment, local weed mulching and ethephon (30 ppm) was appropriate for obtaining maximum yield (8.9 t/ha) as intercrop in guava orchard.
