Application of enhances salt tolerance and yield of Indian mustard through increasing antioxidant enzyme activity.

Growth and yield reduction of crops due to salt stress have become a serious issue worldwide. is very well known as a plant growth-promoting fungi under abiotic stress conditions. Therefore, this study was designed to investigate the effect of on the growth, yield, nutrient uptake, and antioxidant activity of three Indian mustard genotypes under saline condition (EC 9.28 dS m). A two-factorial ( and Indian mustard genotypes) pot experiment was conducted following a completely randomized design (CRD) with four replicates. was applied to soil as compost and suspension. The BD-7104 genotype showed better performance than Tori-7 under saline conditions. Compared to control, application of showed better performance in enhancing growth and yield of all the genotypes by increasing plants' tolerance to salt stress. Again, application increased the chlorophyll, proline, and oil content of Indian mustard. The generation of antioxidant enzymes viz., SOD, CAT, APX, and POD was significantly increased and, synthesis of HO and MDA was decreased to a variable degree under different treatments. On average, application of as compost enhanced seed yield by 23 % than control. The better growth and yield in treated plants were the results of better uptake and assimilation of N, P, S, Ca, Mg, and K and reduced uptake of Na with a lower Na/K. Overall, BD-7104 genotype can be grown in soil treated with as compost at a rate of TdC for obtaining better yield and nutritional quality under salinity stress condition.
