ABSTRACT
A field experiment was conducted at Agricultural College Farm, Raichur during kharif 2008 to find out optimum dose of fertilizer to intercropping system and to assess the economic feasibility and assessment of yield advantages viz., pigeonpea equivalent yield, land equivalent ratio and area time equivalent ratio. The experiment was laid out in randomized block design with three replications. There were 11 treatment combinations. Application of 100% recommended dose of fertilizer to both the component crops in pigeonpea + sunflower intercropping system significantly increased the yields of both the crops over unfertilized control and other lower doses of fertilizers. The maximum pigeonpea equivalent yield (25.82 and 26.77 q ha-1), land equivalent ratio (1.61 and 1.66),area time equivalent ratio (1.21 and 1.25), gross returns (` 77,448.00 and ` 80,302.00 ha-1), net returns (` 59,718.00 and ` 62,308.00 ha-1) and benefit cost ratio (3.37 and 3.46 ) were recorded when full recommended dose of fertilizer was applied to the both the component crops of the system (T2 and T9, respectively)
Key words :
Economics, intercropping system, land equivalent ratio, pigeonpea, equivalent yield.
