Moench]. The experiment consisted of seven treatments, viz. 25% N through FYM + 75% N through inorganic fertilizer, 25% N through fortified vermicompost + 75% N through inorganic fertilizer, 25% N through vermicompost + 75% N through inorganic fertilizer, 50% N through FYM + 50% N through inorganic fertilizer, 50% N through fortified vermicompost + 50% N through inorganic fertilizer, 50% N through vermicompost + 50% N through inorganic fertilizer and recommended dose of fertilizers. The result of two years study revealed that the use of 50% N through fortified vermicompost + 50% N through inorganic fertilizer resulted in significantly highest seed yield of 694.4 kg/ha and 745.4 kg/ha during 2012 and 2013, respectively. Significantly higher number of capsules/plant, seeds/capsule and long capsules with the application of 50% N through fortified vermicompost + 50% N through inorganic fertilizer were recorded. Application of 50% N through fortified vermicompost + 50% N through inorganic fertilizer resulted in significantly higher net returns (180.2 x10(3) (sic)/ha/year) and net returns per rupee invested ((sic)4.91). Moreover, seed quality parameters were also enhanced with the application of 50% N through fortified vermicompost + 50% N through inorganic fertilizer over other treatments. 收起
