Welcome to Rubber Science

Rubber Research Institute of India ( RRII ) under Rubber Board, Ministry of Commerce & Industry, Government of India, Kottayam, Kerala, India has been publishing a peer reviewed scientific journal named Indian Journal of Natural Rubber Research since 1988. This was renamed as Natural Rubber Research in 2004 and subsequently as Rubber Science in 2012, reflecting its widening scope and inclusive nature in tune with the changing trends in rubber research in India and outside.

Highlights of the research findings in this issue are:
  • Riding on the last planting boom (2005 - 2015), rubber production capacity is currently on the rise. As of 2020-21, nearly 41 percent of the mature rubber holdings are over 25 years old. Share of old/senile holdings will further increase and rubber production capacity is destined to decline from the middle of the current decade
  • Rubber growing soils of South India are deficient in zinc warranting application of zinc fertilizer
  • Incidence of tapping panel dryness (TPD) seems to be less in regions receiving relatively less rainfall and propensity for TPD is twice high in BO-2 than in BO-1 panel
  • Anatomical traits of petiole are reliable features for identification of RRII 400 series clones
  • Low Frequency Controlled Upward Tapping is feasible and profitable
  • Rubber plantations are excellent repositories of soil organic carbon. In South India, this ranged from 36.5 to 61.4 tonnes ha-1 in the top 0-30 cm of the soil
  • Vertical tapping can be adopted as a crop harvesting method of natural rubber
  • Girth potential of clones in monoclonal blocks is influenced by assorted rootstocks
  • ITS-RFLP based molecular characterization of isolates of Phytophthora spp causing abnormal leaf fall in natural rubber confirmed the species as Phytophthora meadii
  • The effect of radiation induced peroxide vulcanization on the mechanical properties of NR latex evaluated with addition of n-butylhydroperoxide
  • Tapping mature holdings is still a profitable option provided low frequency tapping is followed, tapping is limited to peak yielding season and self-tapping is adopted. Leaving mature rubber holdings untapped is a lost economic opportunity for the grower
