The study was carried out during Kharif and rabi season of2016-17 and 2017–18 at different locations. Existing farmers’ practices were treated as control for comparison with recommended practices. All the demonstrations have been carried out with an objective to demonstrate how double cropping can be adopted such as rice followed by toria which can be adjusted in a cropping system considering the early harvesting of the first crop rice so that toria seeds can be sown on recommended date as per package of practice. The improved technologies consisting use of medium duration rice variety TTB 404, Toria variety TS 36 and TS 38, balanced fertilizer application and other cultural practices. Rice and toria cropping system gave the average rice equivalent yield of33.15q/ha compared to 24.69q/ha obtained at farmer's practice. The average percentage increase of rice-toria system in two years recorded 34.3percentover farmer's practice. The cropping system with improved varieties recorded higher average gross return (Rs 92, 064/-), net return (Rs.45, 535/-)with higher benefit cost ratio(1.99)as compared to farmer's practices.
