Abstract
Chickpea (Cicer arietinum L.) is important legume crop after soybean and peas and about 15
% of the World’s total pulses production belongs to this crop. It also considered as alternate of
meat in many countries due to high protein content. Global climate change is a severe threat to
chickpea crop production in Pakistan and all over the globe. It inflicts severe decrease in crop
production and yield. The present study was focused on the impact of biogenic Iron and Copper
nanoparticles on growth and antioxidant parameters of the Chickpea crop. This study was
conducted in pots and 5 kg soil capacity pots were used. Nanoparticles were applied through
foliar application. Five different levels of Iron oxide and Copper nanoparticles (0, 25, 50, 75
and 100 ppm) were applied. Physical growth parameters (root length, shoot length, shoot
weight and root weight) were studied. Physiological parameters (chlorophyl content,
carotenoids, phenolics) and antioxidants parameters (H2O2, SOD, POD, CAT, MDA) were also
determined. Results showed that Iron oxide nanoparticles have increased the growth and
physiochemical parameters up to 100ppm concentration of iron oxide nanoparticles. Oxidative
stress parameters decreased with the increasing concentration of iron oxide nanoparticles.
Copper nanoparticles also improved all the parameters as compared to control till 75 ppm
concentration but after that concentration it caused toxicity and decreased physical growth
parameters and physiochemical parameters. We can conclude that foliar application of biogenic
iron nanoparticles has more positive impact on growth and antioxidant parameters of chickpea
crop as compared to biogenic copper nanoparticles.
