Abstract:
A field experiment was conducted during kharif 2021, to study the physiological responses of ferrous sulphate and zinc sulphate on mung bean. The experiment was laid down in randomized block design with sixteen treatments and three replications at research farm of Botany Section College of Agriculture, Nagpur. The aim of this work was to study the effect of foliar application of ferrous sulphate and zinc sulphate at T₁ (CONTROL), T₂ (FeSO₄ @ 0.50%), T₃ (FeSO₄ @ 0.75%), T₄ (FeSO₄ @ 1.00%), T₅ (ZnSO₄ @ 0.50%), T₆ (ZnSO₄ @ 0.75%), T₇ (ZnSO₄ @ 1.00%), T₈ (FeSO₄ @ 0.50% + ZnSO₄ @ 0.50%), T₉ (FeSO₄ @ 0.50% + ZnSO₄ @ 0.75%), T₁₀ (FeSO₄ @ 0.50% + ZnSO₄ @ 1.00%), T₁₁ (FeSO₄ @ 0.75% + ZnSO₄ @ 0.50%), T₁₂ (FeSO₄ @ 0.75% + ZnSO₄ @ 0.75%), T₁₃ (FeSO₄@ 0.75% + ZnSO₄ @ 1.00%), T₁₄ (FeSO₄ @ 1.00% + ZnSO₄ @ 0.50%), T₁₅ (FeSO₄@ 1.00% + ZnSO₄ @ 0.75%) and T₁₆ (FeSO₄ @ 1.00% + ZnSO₄ @ 1.00%). on biochemical parameters and yield in mung bean. Spraying of ferrous sulphate and zinc sulphate was done two times i.e., on 20 and 35 DAS. Observations about biochemical parameters like leaf chlorophyll, nitrogen content in leaves and protein content in seed were also estimated. Observation on yield contributing parameters like 100 seed weight (g), number of pods plant^-1, grain yield plant^-1, plot^-1, ha^-1, harvest index recorded. Foliar sprays of FeSO₄ @ 0.50% + ZnSO₄ @ 1.00% followed by FeSO₄@ 0.75% + ZnSO₄ @ 1.00% significantly enhanced biochemical parameters and yield contributing parameters when compared with control and rest of the treatments under study.
