Effect of Micronutrients Application on Growth Attributes of Wheat in Irrigated Plains of Northwestern Rajasthan

A field experiment was conducted during the Rabi season of 2024-25 at Instructional Agronomy Farm, Tantia University, Sri Ganganagar, Rajasthan, India, to evaluate the effect of foliar-applied micronutrients on the growth and yield parameters of wheat (Triticum aestivum L.). The experiment was laid out in a Randomized Block Design with eight treatments, including a control, replicated thrice. Treatments comprised various combinations and concentrations of zinc (ZnSO₄), manganese (MnSO₄), and iron (FeSO₄) as foliar sprays. Results demonstrated that micronutrient application significantly enhanced plant growth and yield attributes compared to the control. The combined foliar spray of 2.0 kg ZnSO₄ + MnSO₄ + FeSO₄ ha^-1 (T7) proved most effective, producing the maximum plant height (96.34 cm), leaf length, dry matter accumulation (872.80 g plant^-1), number of tillers (489.69 m^-1), and spike length (14.76 cm) at harvest. It was concluded that the foliar application of a balanced micronutrient mixture containing zinc, manganese, and iron is a highly promising strategy for optimizing wheat productivity in the irrigated plains of northwestern Rajasthan.
