Mitigation of the adverse effects of soil salinity in rice using exogenous proline and organic manure

Salinity causes cellular damage and limits crop productivity. Accumulation of organic compound is one of the major adaptive mechanisms for salinity tolerance in plants. The main objective of the present study was to mitigate the adverse effects of soil salinity in rice through organic amendments like proline and organic manure. The field experiments were conducted at the farmer’s field of Batiaghata upazilla under Khulna district with aman rice. The soil was silty clay loam having pH 7.2, EC 6.6 dS/m, CEC 26 meq/100 g soil and organic matter 0.84%. Rice variety BR 23 was used as a test crop. There were 15 treatment combinations with different doses of proline and organic manures. Recommended doses of N, P, K, S and…
