Direct seeded rice, puddled, unpuddled, zero tillage, reduced tillage, weeds

Field experiment was conducted at CCS HAU College of Agriculture Farm, Kaul, Haryana during kharif 2005 and 2006 to find out effective and viable system of controlling complex flora of weeds in direct seeded rice. Among different herbicidal treatments, pendimethalin at 1.5 kg/ha (PE) and cyhalofop butyl at 90 g/ha controlled Echinocloa very effectively but failed to check Cyperus, whereas pretilachlor+safener at 0.5 kg/ha provided excellent control of Cyperus. The grain yield was almost similar under the treatment of pendimethalin at 1.5 kg/ha fb HW at 30 DAS in all the sowing methods. Under wet seeding methods, pre-emergence application of pretilachlor+safener resulted in significantly higher grain yield of rice, whereas under dry seeding methods higher grain yield was recorded in the treatment of pre-emergence application of pendimethalin
