Abstract
An experiment was conducted during the rainy seasons of 1998 and 1999 at the research farm of Rajendra Ag ricultural University, Pusa, Samastipur, to study the effect of maize (Zea mays L.) based intercropping systems on maize yield and associated weeds under rainfed condition. lntercropping systems reduced the values of yield at tributes and grain yield of maize than sole cropping of maize, but significant reduction in cob length, kernelslrow, grainslcob and grain yield was recorded only with sesame (Sesamum indicum L.), turmeric (Curcuma longa L.) and forage meth [Phaseolus aconitifolius (Jacq) Marechal] intercropping systems. All intercropping systems re corded significantly higher maize equivalent yield, productivity (kglhdday) and significant reduction in weed popu lation and weed dry biomass than sole cropping of maize. Among the intercropping systems, maize turmeric showed significantly higher maize equivalent yield and productivity (kglhdday), however significantly lower values of these were associated with maize sesame. Maize forage meth recorded the lowest weed population, weed dry biomass and highest weed control efficiency. Highest weed population, weed dry biomass and lowest weed control efficiency were found with maize pigeonpea [Cajanus cajan (L.) Millsp.] intercropping system.
