Abstract
An experiment was conducted on the Research Farm of the Department of Agronomy, Agrometeorology and Forestry, PAU, Ludhiana, during 2005 and 2006 in order to find out effective weed management methods for controlling hardy weeds of maize crop such as Acrachne racemosa, Commelina benghalensis and Brachiaria reptans, etc. During 2005, all the weed control treatments except alone application of pendimethalin 1.0 kg/ha and alachlor 2.5 kg/ha produced significantly higher grain yield and less dry matter accumulation by weeds as compared to the recommended herbicide i. e. atrazine 1.0 kg/ha. During 2006, tank mix application of atrazine 0.75 kg + pendimethalin 0.50 kg/haproduced significantly higher grain yield as compared to recommended herbicidal treatment. On the basis of mean values, it may be concluded that tank mix application of atrazine 0.75 kg + pendimethalin 0.75 kg/ha, atrazine 0.75 kg + alachlor 1.25 kg/ha and atrazine 0.75 kg + trifluralin 1.2 kg/haincreased grain yield of maize by 48.3, 53.9 and 49.7% over unweeded control. Also integration of HW with pre-emergence application of atrazine 0.75 kg/ha, atrazine 0.50 kg + pendimethalin 0.50 kg/ha, atrazine 0.50 kg + alachlor 0.75 kg/ha and atrazine 0.5 kg + trifluralin 0.60 kg/haproduced significantly higher grain yield and less dry matter accumulation by weeds than pre-emergence application of atrazine 1.0 kg/ha and all these treatments increased grain yield by 68.4, 71.6, 64.6 and 68.9% over unweeded control and 14.7, 17.0, 12.2 and 15.2% than atrazine 1.0 kg/ha.
