Effect of weed management practices on weed dynamics, growth, yield and economics spring sugarcane (Saccharum officinarum L.)

Abstract

A field experiment was conducted to assess the performance of different weed management practices in spring sugarcane var. Co 86032 during year 2008-09 to 2010-11 at Central Sugarcane Research Station, Padegaon. In spring planted sugarcane application of Metribuzine @1 kg a.i. ha-1 as PE +2, 4-D @ 1 kg a.i. ha-1 spray at 60 DAP + hoeing at 90 DAP found superior for control of weed in sugarcane with the highest weed control efficiency (80.80) at 120 DAP and also recorded significantly highest cane and CCS yield (115.52 and 17.33 t ha-1 respectively), Net profit (₹ 54628 ha-1) and benefit cost ratio (1.72). Application of Atrazine @ 2 kg a.i. ha-1 as PE +2, 4-D @ 1kg a.i. ha-1 as PoE at 60 DAP + hoeing at 90 DAP was found the next best treatment for weed control in sugarcane.
