ABSTRACT
Spring planted popular plants produced and average 30.5g biomass as Compared to 11.5g biomass produced by late summer planted plants. The water use efficiency of spring sown popular plants was 358g and 333g in mulched and unmulched pots respectively while for late summer sown plant it was 381g and 342g respectively in mulched and unmulched pots. This indicated that seasonal differences have little effect on water use efficiency of popular plants. However, mulched plants were less efficient user of water than unmulched plants both in the spring and late summer season. The relative amount of water evaporated by mulched and unmulched pot soil was approximately 50 and 70 percent less respectively over the free water surface.
