respectively at 60 DAE (Fig. 2). Significant reductions in
chlorophyll content were recorded under ACO2+ AO3 and
ACO2+ EO3 compared to ACO2+ RO3 at both the ages. Carotenoids content showed an increase under ECO2+ AO3 and
ECO2+ EO3 by 28.17 and 31.6% at 30 DAE compared to
ACO2+ AO3, whereas a reduction by 57% under ACO2+ EO3
and no variation under ACO2+ AO3were recorded compared to
ACO2 (Fig. 2). Three way ANOVA test indicated that total
chlorophyll and carotenoids contents varied significantly due to
all the individual factors and their interactions except due to
age for chlorophyll (Table 1)
