Effect of weed control and intercropping systems of maize and sesame with groundnut on weeds, yields and yield components.

Abstract: The present experiment was carried out in Shandaweel Agriculture Research Station, Sohag governorate, Egypt during 2005 and 2006 summer seasons to study the effect of three weed control treatments (Pendimethalin herbicide, hand hoeing twice and untreated) and intercropping systems of maize and sesame with peanut on weeds, yield and yield components. The intercropping systems were pure stand peanut, peanut + maize (100:100%), peanut + maize (100:50%), peanut + sesame (100:100%) and peanut + sesame (100:50%). Peanut was planted on one side of the ridge in all mixed intercropping systems, while maize and sesame were planted on other side of all peanut ridges (100:100%) and on one side of peanut ridges and leaving one side of peanut ridge without intercropping (100:50%). A split plot design with three replications was used. Results indicated that effect of intercropping system and weed control treatments on dry weight of weeds (g m-2) in both seasons were significant. Intercropping peanut + maize (100:100%), maize sole crop and sesame sole crops resulted in the highest reduction in dry weight of weeds compared to peanut sole crop. The effect of intercropping systems and weed control treatments on yield and yield components of peanut were significant in both seasons except number of branches and filling% in first season. Peanut sole crop, peanut + sesame (100:50%) and peanut + maize (100:50%), gave the highest values for pod yield compared to peanut + maize (100:100%). In maize, most characteristics under study was significantly affected by intercropping systems. Maize sole crop and peanut+ maize (100:50%) gave the highest values for seed yield compared to peanut + maize (100:100%). However, intercropping sesame with peanut significantly affected seed yield plant-1, 1000-seed weight, and seed yield in both seasons and plant height in second season only. Sesame sole crop and intercropping peanut + sesame (100:50%) gave the highest values of seed yield compared to peanut + sesame (100:100%). Hand hoeing twice and Pendimethalin herbicide gave the highest values for most characteristics under study for all crops compared to untreated. Interactions between intercropping systems and weed control treatments were non-significant for most characteristics under study for all crops. The highest value of LER was obtained from intercropping peanut + maize (100:50%) and peanut + sesame (100:50%). The highest value of net return was obtained when peanut was intercropped with sesame (100:50%) with hand hoeing twice.
