Foliar application of macro and micronutrients plays a vital role in improving plant growth and physiological processes, especially in rainfed conditions where nutrient availability is limited. Rice (Oryza sativa L.), a staple crop, requires an adequate supply of essential nutrients for optimal growth and productivity. This study aimed to evaluate the impact of foliar application of macro and micronutrients on the growth and physiological traits of rice grown under rainfed conditions.
Research was carried out at the Student's instructional farm, Acharya Narendra Deva University of Agriculture and Technology, Ayodhya, India, during the Kharif season usingrandomized block design with nine treatments and three replications on the rice variety Sahbhagi Dhan. Treatments included foliar application of KCl (0.5%, 1.0%), MgSO4 (1.0%, 2.0%), boric acid (0.3%, 0.6%) and salicylic acid (0.25%, 0.5%), applied twice during the vegetative and grain filling stages. Data were recorded on growth parameters such as plant height, number of tillers plant-1 and dry weight plant-1, as well as physiological traits including relative water content, chlorophyll, proline, catalase and peroxidase content at 30, 60 and 90 days after transplanting.
Study showed that foliar application of macro and micronutrients significantly influenced the growth and physiological traits of rice. Among the treatments, 1.0% MgSO4 led to the most notable improvements. Statistical analysis confirmed the significance of foliar nutrients application for several traits at the 5% probability level. The findings suggest that foliar nutrient application enhances rice yield by supporting plant metabolic processes and enzyme activation, ultimately improving vegetative growth and productivity.
