Abstract

During the Rabi season of 2022 – 23, we conducted a field experiment at Lovely Professional University’s Agronomy Farm in Phagwara to assess the impact of a combined application of growth regulators, namely indole acetic acid (IAA) and salicylic acid (SA), and micronutrients zinc (Zn) and iron (Fe), on the growth parameters of toria. Our results revealed that the application of IAA at a concentration of 0.1 g/l, in conjunction with SA at 0.15 g/l, along with Zn (0.05 g/l) and Fe (0.015 g/l), led to a substantial improvement in growth parameters. These included increased plant height, more excellent primary branches, a higher leaf count, an elevated leaf area index, and enhanced chlorophyll content. Remarkably, these outcomes were on par with those obtained from the application of IAA at 0.2 g/l and SA at 0.3 g/l, combined with ZnSO4 (0.05 g/l) and FeSO4 (0.015 g/l), surpassing the results of individually applied IAA and SA. Conversely, the control treatment exhibited the least favorable growth parameters. Overall, the adoption of such practices not only enhances rapeseed productivity but also contributes to sustainable food production systems, bolstering food security efforts on a global scale.
