Treatment effects on petiole length, leaf length and leaf width
were significant, with the treatment receiving conjunctive application
of CT and NPK at 50% giving the highest values, whereas the
control treatment gave the lowest values. The highest leaf area of
31.0cm2 was observed with the CT50 +NPK50 treatment, whereas a
leaf area of only 8.29cm2 was obtained in the control. The highest
specific leaf area (253cm2 g−1) was obtained in the control treatment,
whereas lower specific leaf areas were recorded in all other
treatments. The application of nutrients in any form promoted
the formation of thicker leaves than in the non-fertilised plants
(Table 3).
