| description | Split plot design experiments were conducted to assess the performance of growth regulating compounds for mitigating moisture stress and the incidence of Brown Plant Hopper (BPH) in rice. The main plot treatments (4) comprised moisture stress free control (M<sub>1</sub>), moisture stress during panicle initiation stage alone (M<sub>2</sub>), moisture stress during flowering stage alone (M<sub>3</sub>), and moisture stress during both panicle initiation and flowering stages (M<sub>4</sub>). The sub-plot treatments (5) were foliar application of growth regulating compounds including chlormequat chloride at 200 ppm (S<sub>1</sub>), mepiquat chloride at 200 ppm (S<sub>2</sub>), brassinolide at 0.1 ppm (S<sub>3</sub>), pink pigmented facultative methylotrophs (PPFM) at 1% (S<sub>4</sub>), and no spray control (S<sub>5</sub>). The reduced plant growth attributes were registered under moisture stress at both panicle initiation and flowering stages. The spraying of 1% PPFM during the flowering or both at panicle initiation and flowering stages led to better performance than the other treatments. Also, spraying 1% PPFM brought down the population of BPH to a considerable level during both years of experiments. This suggests that spraying 1% PPFM in the post-flowering stage helps to mitigate the ill effect the moisture stress and BPH incidence. |
