Application of sodium nitroprusside on rubber seedlings grown in a glass house has improved the growth and root architecture while tolerable to heat stress conditions

Priming of rubber seeds with different chemicals has improved the germination percentage and seedling vigor

Plant selection in the nursery on the basis of girth continues to show a correlation between the initial girth and the girth in field plants up to commencement of  tapping.

 
Irrigation has improved the growth of plants in rubber nurseries as well as the productivity in nurseries.

IPlanting cinnamon at 4m x 3m in the 14m inter-row spaces of rubber can hold about 75% of the sole crop stands.  Rubber x Cinnamon system pays back the entire cost of both crops in 5 years

Low frequency tapping with stimulation seems to solve the tapper problem to a certain extent while assuring a reasonable period for bark renewal
