The
negative response of fresh and dry weight to increasing
temperature may be due to reduced leaf area expansion,
smaller amount of radiation received, thus less
photosynthesis (Wahid et al., 2007). Panicum coloratum
showed the highest value of fresh weight (Figure 5)
producing (739.0 g) biomass at T3 level and minimum
(533 g) was observed in Panicum antidotale. Statistical
mean values of fresh weight of different Panicum species
at different treatment level indicated that at T3 level
maximum fresh weight was observed and minimum at T0
level. Panicum coloratum showed the height value of dry
weight (Figure 6) producing 268 g biomass at T3
treatment, on the other hand lowest value (153 g) of this
character was recorded in Panicum antidotale. The
maximum mean value of dry weight was observed at T3
level and minimum at T0 treatment.
Fresh and dry matter production in plants is
directly correlated with the
