Online Published on 07 May, 2022. Abstract Field experiment was carried out at the Department of Millets, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu during kharif 2020 to study the influence of agro-ecological interventions for fall armyworm (FAW) management involving different intercrops in maize. The experiment was laid out in a randomized complete block design with the five treatments viz T1- Maize + Tephrosia, T2 - Maize + fenugreek, T3- Maize + coriander, T4- Maize + marigold and T5- Maize alone, replicated thrice. A row of C:N hybrid grass was planted in the brim of the field. It was found that among the intercropping systems in maize, maize + marigold was found to be superior for the management of FAW in maize which recorded higher maize equivalent yield of 6,215 kg/ha, net return of Rs 47,181.00/ha and B-C ratio of 1.87.
