Abstract

Two experiments were carried out in this study. Experiment I has been conducted with Treatments: Factor A: Row arrangement i.e., Regular (1:1) and Paired (2:2), Factor B: with intercrop i.e. Maize + Mungbean, Maize + Cowpea, Maize + Groundnut, Maize + Soybean, Sole maize. Experiment II: includes Push-pull strategy for Fall Army Warm (FAW) management during Kharif with treatments 1. Maize + Tephrosia, 2. Maize + Fenugreek, 3. Maize + Coriander, 4. Maize + Marigold (*A border row of hybrid napier to be planted for pulling FAW). Among the different intercropping based strategies in the row arrangement, significantly the highest maize grain yield was observed with regular row arrangement. However, the intercropping systems significantly the highest maize grain yield was recorded with maize + green gram and sole maize system. In-terms of FAW infestation and severity no difference was observed among the row arrangement. But significantly lesser FAW infestation and severity observed from 50 DAS to harvest with maize + green gram intercropping when compare to the other intercropping’s. Higher FAW infestation and severity was observed in all the Push-pull strategy treatments.
