Abstract:

A study was conducted to assess the effect of pink pigmented facultative methylotrophs (PPFM) on the seedling emergence behavior of rice, during the summer season at the Integrated Farming System Research Station, Karamana, Thiruvananthapuram, Kerala. The experiment was laid out in completely randomized design with six treatments and four replications. The treatments consisted of five superior isolates of PPFM (PPFM 16, PPFM 26, PPFM 35, PPFM 37, PPFM 38) compared against a control (distilled water). Irrespective of the PPFM isolates hundred per cent emergence was observed. A higher emergence rate index (160) was observed for rice seeds treated with PPFM 38. Seedling root length recorded significant variation among the different PPFM isolates, with PPFM 38 proving to be superior. The same trend was observed with dry weight of seedlings also. The seedling vigour expressed as vigour index I and II were observed to be superior with seed treatment of PPFM 38 and PPFM 37 respectively. When compared to distilled water, seed treatment with PPFM elicited better seedling characters. The study revealed that seed treatment with PPFM could enhance the emergence and seedling vigour of rice.
