Performance of different zinc sulfate level on survival, morphological and biochemical parameters of Sub1 and Non-Sub1 rice varieties under submerged condition

Abstract

An experiment was performed to evaluate the impact of zinc sulfate by examining survival rate, growth attributes, and biochemical parameters under the submerged and non-submerged conditions to enhance submergence tolerance in Sub1 and non-Sub1 rice varieties. A fully randomized block design was followed with three treatments, three replications, and five chosen rice varieties centered on submergence resistance and susceptibility. Sowing seed s directly with the treatments comprises viz. T1: 0.0 mg ZnSO4 per kg of soil, T2: 5.0 mg ZnSO4 per kg, T3: 10 mg ZnSO4 per kg of soil. Treatments were performed in both submerged and non-submerged (controlled) pots at sowing. After 30 days of sowing, fifteen days of full sub mergence. It follows that zinc sulfate @10 mg/kg soil greatly improved survival percentage, growth qualities, and biochemical parameters of Sub1 and nonSub1 rice varieties even after 15 days of total submergence.
