Abstract:

In order to evaluation of effect of popcorn + cowpea intercropping on yield and weeds biomass an experiment was conducted as factorial based on RCB in Islamic Azad University of Tabriz. Studied factors included maize sowing dates (12th, 19th and 26th May) and sowing percentage of cowpea as 12.5%, 25%, 37.5%, 50% and 100% of recommended density rate (5, 10, 15, 20 and 40 plants per square meter). Based on results weeds biomass in intercropping of the crops with 12.5% and 25% of recommended density rate experienced reduction of 4.5 g m-2 compared to the maize mono-cropping and 6 g m-2 compared to the mean of intercropping of the crops with 37.5% and 50% of recommended density rate. Intercropping of popcorn with cowpea with 12.5% and 25% of its recommended density was recommended for farmers.
