Effect of soil and foliar application of zinc and iron on productivity and quality of wheat

V. PALLAVI, T. SUDHA

Abstract


A field experiment was carried out during rabi season of 2015-16 to study the ‘effect of of zinc (Zn) and iron(Fe)application on productivity and quality of wheat’ at Main Agricultural Research Station, Dharwad. The experiment waslaid out in a Randomized Complete Block Design (RCBD) having fifteen treatments and replicated thrice. A common doseof 100 N: 75 P2O5: 50 K2O kg ha-1 was applied to all the plots. Along with recommended dose of fertilizer ZnSO4 and FeSO4were applied to soil at the rate of 20 kg ha-1. Two foliar application of ZnSO4 and FeSO4 each @ 0.5 % were made at headingstage and at milking stage. Wheat crop (Var. UAS-428) responded significantly to the soil and foliar application of Zn andFe. The higher number of productive tillers m-2 (273.3), weight of grain per ear head (1.47 g), 1000 grain weight (43g), earhead length (6.79 cm), number of filled grains (281), number of chaffy grains (10.7), spikelet fertility (86.1 %), grain yield((38. q ha-1) and biomass yield (100.7 q ha-1) were recorded with soil (20 kg ha-1) and foliar application (0.5 %) of Zn atheading and milking stage. Quality parameter like protein (14.2 %), sedimentation value (37.67 ml) was significantly higherdue to soil and foliar application of zinc at heading and milking stage as compared to other treatments and found on par withsoil and foliar application of iron at heading and milking stage, soil and foliar application of zinc at milking stage and soil andfoliar application of iron at milking stage.
