Abstract


A field experiment was conducted for three years (2003, 2004 and 2005) during kharif season at Zonal Agricultural Research Station, Shimoga, Karnataka. Sole crop of FCV tobacco was compared with maize, chilli, groundnut, red gram, cotton, french bean and intercrop of maize + red gram (2:1), groundnut + red gram (4:1), hybrid cotton+chilli+groundnut (3rows) and hybrid cotton + chilli + french bean (3rows) in randomized RCBD design. Tobacco crop performed better in terms of gross and net returns (Rs.19,720/ha) as it fetched higher price in the market. Among the sole crops tried, chilli and french bean were the next best remunerative crops as they recorded higher net returns of  Rs. 15,080/ha and  Rs.13,410/ha, respectively. Maize+redgram (2:1) and groundnut +redgram (4:2) achieved higher benefit cost ratio compared to tobacco. These intercropping combinations performed better with respect to land equivalent ratio and relative crowding coefficient (>1). Both the high intensification cropping systems viz., cotton+chilli+groundnut and hybrid cotton+chilli+french bean recorded maximum net returns ( Rs.22,707/ha and 21,832/ha), benefit cost ratio (2. 26 and 2.37) and highest land equivalent ratio (1.59 and 1.66) and can be economically viable alternate to FCV tobacco.
