A field experiment was conducted on ratoon crop of sugarcane to develop suitable weed management practices during spring seasons of 2005 to 2009 at Central Sugarcane Research Station, Padegaon, Tal. Phaltan, Dist. Satara, Maharashtra, India. A total of ten treatments including weedy check were tested in randomized block design with three replication. Trash mulching between all rows with recommended practice applied in the ratoon recorded significantly the highest cane (98.00 t/ha) and CCS yield (15.50 t/ha). However, it was found at par with application of trash mulching in alternate rows + hoeings at 1st and 6th week after ratoon initiation, (95.28 t/ha) and in treatment of three hoeings (1st week, 4th week and 7th week after ratoon initiation), (93.99 t/ha) with respect to cane yield. Significantly higher net monetary returns ( 69719 /ha) were obtained in application of trash mulching between all rows with recommended practice which was followed by trash mulching in alternate rows + hoeings at 1st and 6th week after ratoon initiation ( 65841 /ha ) and three hoeings ( 1st week. 4th week and 7th week after ratoon initiation ) ( 63614 /ha).
