An experiment was conducted during the rabi seasons of 2006–07 and 2007–08 to study the effect of different planting patterns viz., zero till so wing with Happy Seeder(combine harvested), zero till so wing in standing stubbles(loose straw removed), zero till sowing (complete burning of rice straw), bed sowing (rice straw removed) and conventional tillage (partial burning of rice straw)and weed control treatments viz., sulfosulfuron 25 gha−1,mesosulfuron+iodosulfuron 12g ha−1, pinoxaden 50gha−1andcontrol(unweeded) on productivity and quality of wheat. The experiment was laid out in stripplot design with planting patterns of wheat in main plots and weed control treatments in sub-plots. Grain yield of wheat was not significantly influenced by different planting patterns but was significantly higher in all the three herbicidal treatments than control. Further, all the herbicidal treatment swere statistically at par with each other in case of grain yield during both the years of in vestigation. There was non-significant differences in thousand grain weight, hectolitre weight, sedimentation value and protein content of wheat grain under different planting patterns. Thousand grain weight, hectolitre weight and sedimentation value were significantly higher in herbicidal treatments than control (unsprayed) crop.
