Abstract
Being the most important cereal crop higher production of wheat is a major concern in the present scenario. Wheat field is generally infested from wide range of monocot and dicot, grassy and non-grassy weeds. This investigation was conducted to find a suitable herbicide mixture that can improve the growth of wheat plant as compared to the weedy checks. The study conducted twelve treatments which were replicated four times. The weed management treatments included T1: pendimethalin 1000 g a.i. ha-1 (PE), T2: pendimethalin 1500 g a.i. ha-1 (PE), T3: pyroxasulfone 127.5 g a.i. ha-1 (PE), T4: pendimethalin +pyroxasulfone 1250 + 127.5 g a.i. ha-1 (tank mix PE), T5: pyroxasulfone + metsulfuron 127.5 + 4 g a.i. ha-1 (PE), T6: pyroxasulfone 127.5 g a.i. ha-1 (EPOST), T7: pyroxasulfone + metsulfuron 127.5 + 4 g a.i. ha-1 (tank mix EPOST), T8: metribuzin 300 g a.i. ha-1 (PE), T9: pendimethalin + metribuzin 1250 + 280 g a.i. ha-1 (tank mix PE), T10: pyroxasulfone + metribuzin 127.5 + 280 g a.i. ha-1 (tank mix PE), T11: weedy check and T12: weed free. It was concluded from the results that the application of T7: pyroxasulfone + metsulfuron 127.5 + 4 g a.i. ha-1 (tank mix EPOST) resulted significantly superior plant height, number of leaves plant-1, leaf area index and dry matter accumulation of plants as compared to weedy check and rest of the treatments.
