Abstract:
Mung bean ranks 3rd largest and an essential edible crop after wheat and rice. Unfortunately, in Pakistan mung bean yield is very low as compared to worldwide production. There are many biotic & abiotic factors which hampered the mung bean production one of the distractive abiotic factors is heavy metal stress such as “Nickel Chloride”. In the present research work the impact of plant extracts (Neem, Java plum & Aloe vera extracts) on the growth of mung bean plant grown under the stress of nickel (Ni) was studied in pot experiment. The experiment was decided in five different sets. Set 1: Aloe vera gel extract (2%, 4%, 6%) + 350 mg kg-1 Ni, Set 2: Java plum leaf extract (2%, 4%, 6%) + 350 mg kg-1 Ni, Set 3: Neem leaf extract (2%, 4%, 6%) + 350 mgkg-1 Ni, Set 4: 30 ml of 350 mgkg-1 Ni (+ive control), Set 5: Negative control that received only tap water. Moreover, the experiment was comprised of eleven treatments having three replicates with completely randomized design. Different growth parameters such as plant height, root, shoot length and biomass (fresh & dry) were studied after 15 days of seed germination. Moreover, various physiological attributes such as total chlorophyl content (TCC) & reducing sugar (SUG) were studied. Furthermore, biochemical traits i.e., total protein content (TPC), catalase (CAT) and per oxidase (POX) activity were also studied. The result revealed that the soil amendments with neem extract at different concentrations (2, 4, 6%) significantly (P = 0.05) increased the growth of the mung bean plant as compared to the respective positive control (350 mg kg-1) while applications of java plum exhibited negative impact on the growth of mung bean plant over negative and +ive control. Hence, neem extracts could be caused to minimize the toxic effect of nickel in soil. So far, further details studied are required in field level too for the better yield of mung bean plant.
