Abstract: Around 20% of irrigated land globally affected due to salinity stress. This condition is more severe in some states where the effect is more than 35%. Salinity stress caused mainly due to two reasons one of them is the poor quality of irrigated water and other is the excess concentration of salts present in the soil. There are two different mechanisms in plants in response to salt stress, which further provides signals to various parts of plants and enacts according to that response. Based on the ability to tolerate the stress plants classified as glycophytes, which can tolerate a low level of saline stress while others are halophytes, which can tolerate more level of saline stress. Halophytes like mustard can cope up with the situation of salinity stress because they have a special mechanism for it. There many ill effects of salinity stress on mustard plants, which leads to its lower productivity and a lower economic benefit. This saline stress has adverse effects in all around the world along with India, especially in arid regions. There are various mitigation methods to cope with this salt stress and thus preventing its negative effects on production and reduce our economic loss. The application of microbial bio inoculants that are trichoderma, mycorrhiza, rhizobium, and organic compounds that are cycocel and benzyl adenine reviewed in this paper. It also involves various mitigating effects of them, which is, observed by application of them in Mustard plants.
