 Field studies were conducted for two years to determine the effects of intercropping broccoli with onion and different nitrogen concentrations on growth, yield, and nutrient content. The overall efficiency of intercropping was evaluated using land equivalent ratios, L.E.R.s. While cropping systems did not significantly affect chlorophyll reading value, yield, or other parameters observed, nitrogen application rate had a significant effect. The highest values of these parameters were generally observed with 240 kg Ha 1 nitrogen application. Macro and micro-element content of broccoli leaves was affected by nitrogen fertilization except for N, MN, ZN, and NO3. Intercropping increased plant height but decreased the plant diameter of onion. There was no significant decrease in plant weight of intercropped onion at 240 kg Ha 1 nitrogen treatment when compared to monocropping. Broccoli intercropped with onion at 240 kg Ha 1 nitrogen had the highest L.E.R. values, showing that intercropping could be more productive than monocropping especially in case of 240 kg Ha 1 nitrogen application.
