dc.description.abstractThe present study on herbaceous plant diversity of three land use systems viz fallow land, canal bunds and cultivated land at two locations Ludhiana and Sangrur revealed overall sixty seven plant species at these sites. Among these fifty two plants were dicots and fifteen were monocots. Plants were distributed in twenty seven families out of which Poaceae and Asteraceae were dominant. Variations were recorded for plant species in all the land use systems and locations. Only few differences in emergence, flowering, fruiting, seed maturity and senescence of plant species was observed when land use systems were compared. For morphological parameters, the maximum plant height (178.16 cm) and shoot length (183.50 cm) was recorded for Saccharum spontaneum whereas diameter (19.23 cm) was recorded maximum for Ricinus communis and root length (23.5 cm) was maximum for Conyza bonariensis. Diversity indices values showed variations with change in months, land use systems and locations. Among land use systems of both locations, Density/m2 was recorded to be maximum for Parthenium hysterophorus (10.5 m-2) of fallow land (Sangrur) in September and IVI (115) was maximum for Amaranthus viridis of cultivated land (Ludhiana) in June. Comparison of mean values of Shannon Wiener index (2.30) and Brillouns index (2.16) reflected that mean values were maximum for fallow land (Sangrur) which reflected presence of maximum diversity in this system. Simpson diversity index mean values (0.88) were maximum for canal bunds of both locations reflecting maximum diversity of dominant plant species. Eveness index representing equal number of individuals per species was maximum for fallow land (0.77) (Ludhiana) followed by cultivated land. Annual values for total biomass (5733 kg/ha), nitrogen uptake (96.66 kg/ha), phosphorus uptake (21.55 kg/ha) and potassium uptake was recorded to be maximum for fallow land (Sangrur). On monthly basis, for July maximum biomass (3744.33kg/ha), nitrogen uptake (66.15kg/ha), phosphorus uptake (17.71) and potassium uptake (52.03kg/ha) was recorded.en_US
