Studies on hormone treatment of sugarcane

I. Pot experiments with 2, 4-D

  • Published:
Proceedings / Indian Academy of Sciences

V. Summary

(1) Pot culture studies on the effect of 2, 4-D on sugarcane have been reported in the paper.

(2) Soil application of 2, 4-D (amine salt) at planting increases sugar content by about 2·6 units while depressing yield by 40%. Sodium salt of the hormone applied at this stage has no significant effect on yield or quality.

(3) Soil application of both salts, either two weeks after germination or at the time of earthing up, significantly improves sugar content (by 1·8 units) with no significant effect on yield.

(4) The same holds good for foliar application, mean improvement in sugar being 1·5 units.

(5) When applied to soil two weeks after germination, at earthing up or as foliar spray, the two forms of the hormone afford the same order of improvement in sugar (1·6–1·8 units).

(6) The above results conform to the findings of large-scale trials in collaboration with the sugar industry, reported earlier.
