Response of different zinc level on yield of Sub-1 and non Sub-1 rice varieties under submerged condition

Abstract

An experiment was conducted to study the effect of zinc sulphate by assessing yield attributes at before and after submerged condition for improving submergence tolerance in Sub-1 and non- Sub-1 rice varieties. The completely randomized block design was adopted with three treatments, three replications and five rice varieties selected on the basis of submergence tolerance and susceptiblity. Seeds were sown in pot directly with the treatments include viz. T1: 0.0 mg ZnSO4 per kg soil, T 2: 5.0 mg ZnSO4 per kg soil, T3: 10 mg ZnSO4 per kg soil. Treatments were done in submerged and non-submerged (controlled) pots both at the time of sowing. After 30 days of sowing, fifteen days of complete submergence was given. From that, it is concluded that zinc sulphate @10 mg/kg soil significantly enhanced yield of Sub-1 and non Sub-1 rice varieties even after 15 days of complete submergence.
