               ABSTRACT
               Upon increased anthropogenic activities, soils are contaminated with heavy metals which are

               of critical concern in agricultural productions. Fenugreek (Trigonella foenum-graecum L.) is

               an  aromatic  medicinal  herb  of  family  Fabaceae;  its  leaves  and  seeds  have  been  exploited
               immensely  for  medicinal  purposes.  The  current  study  summarizes  the  response  of  an

               environmental pollutant i.e., Cd with different concentrations ranging 20, 40, 60, 80 and 100
               ppm on morphological and yield parameters of Trigonella. Therefore, seed germination, plant

               survival, pollen fertility and morphological attributes were notably reduced with increasing

               Cd concentrations. The maximum reduction was noticed at higher concentration i.e., 80 and
               100 ppm. Consequently, heavy metal is considered as a convenient indicator of tolerance and

               overcome the inimical outcomes of the metals in the environment on plants.

               INTRODUCTION
               Excessive advancements in industrialization and urbanization activities including mining and

               smelting  processes,  the  excess  release  of  major  environmental  pollutants  such  as  heavy

               metals are responsible for soil contamination in turn effecting the plants thus degrading the
               environment (Menon et al., 2016). Heavy metals possess metallic properties with moderately

               high  densities.  Cadmium  (Cd),  the  phytotoxic  element  residing  in  pesticides  is  not
               advantageous and diminishes the crop productivity if their concentration rises beyond optimal

               values  (Tiwari  and  Lata,  2018;  Ghori  et  al.,  2019).  Cadmium  brings  about  metabolic

               disorders and morphological aberrations resulting in  yield reduction. These aberrations are
               known  to  generate  reactive  oxygen  species  (ROS)  (Choudhary  et  al.,  2012;  Amari  et  al.,

               2017).  Plants  under  metal  stress  negatively  effects  the  growth  due  to  heavy  metal
               accumulation (Menon et al., 2016).

               Fenugreek (Trigonella foenum-graecum L.) is an annual leguminous herb of fabaceae family

               widely grown in middle eastern countries. It’s leaves and seeds are extensively consumed as
               condiment in food preparations due to its aroma and flavour. Fenugreek seeds are rich in L-

               tryptophan rich proteins, lysine etc. which possess therapeutic properties (Sadak, 2019). It has
