Conclusion

  • Increased cotton plant height at 25, 40 and 55 DAE.
  • Increased Greenness score
  • Increases in yield and return on investment ($218.50 / Ha) when C active is used with 100% fertilliser.
  • With less fertiliser (37.5kg N) the addition of C active increased yield significantly.

Observation

  • Results suggest C-active Microbial Technology performs well in low yielding and minimal input cotton under subsistence farming.
