PERFORMANCE OF DIFFERENT FENNEL BASED INTERCROPPING SYSTEMS UNDER VARYING NITROGEN LEVELS

Abstract

The field experiment was conducted to study the response of different fennel based cropping systems to varying levels of nitrogen during rabi season of 2000-01 and 2001-02 at Indian Agricultural Research Institute, New Delhi. The fennel + fenugreek intercropping system tended to have the highest seed yield of fennel, fennel seed equivalent of intercrops, total equivalents, net return, net return/rupee invested and uptake of nitrogen, phosphorus and potassiu by fennel. The marked response of fennel and intercrops was found up to the application of three -fourth of recommended nitrogen level in terms of productivity, net return, net return/rupee invested; and concentration and uptake of nitrogen, phosphorus and potassium by fennel.
