- URCU: SK Cote Single 43-0-0+TE
- UU: Urea
- UAS: Ammonia Sulphate
The vegetative study showed that SK Cote Single 43-0-0+TE consistently showed superior performance in terms of girth size, frond length, petiole cross section, leaf dry weight and leaf area index compared to the other treatments. Chlorophyll and nitrogen content studies also showed that nitrogen was supplied at in a sustained manner so that no luxury/starvation curve occured as was common in the other treatments.
