Intercropping of African Marigold with Tomato for Better Productivity, Pest Control and Economic Returns in Arunachal Pradesh, India

The present study highlights about intercropping of African marigold with tomato for better productivity, pest control and economic returns in Arunachal Pradesh, India. This study was carried out during Rabi season of 2017-18 and 2018-19 respectively in Tirap district of Arunachal Pradesh to find out the best line combination of marigold with tomato. Total three treatments were planted with three replications under Randomized block design. T1 recorded minimum infestation of tomato fruit borer (5.47 %), maximum fruit yield (16.32 t/ha), maximum net return (Rs. 1,53,000), Best B:C ratio (3:1) while T3/control recorded least (18.32%, 14.27 t/ha, rs.1,17,780 and 2:43 respectively). It can be suggested to farmers of Arunachal Pradesh that marigold can be used as a trap crop in tomato farming for better production, yield and economics.
