Weed management in direct sown rice

Field experiments were conducted during the wet seasons of 2002, to 2004 at Modipuram to find out the most effective weed control method in direct-swon rice. Results indicated that stale seedbed produced higher rice yield (3.58 t ha⁻¹) as compared to traditional seedbed (3.27 t ha⁻¹). Among weed control treatments, herbicide (Pendimethaline at 1.2 kg a.i. ha⁻¹) + one hand weeding (5.14 t ha⁻¹) and criss- cross sowing + herbicide + one hand weeding (5.52 t ha⁻¹) produced comparable yield but significantly superior to hand weeding under taken twice. The highest net return (Rs 15556 ha⁻¹) was recorded under criss- cross sowing + herbicide+ one hand weeding.
