Effect of integrated weed management practices on growth and yield of suru sugarcane (Saccharum officinarum L.) in sub montane zone of Maharashtra

Abstract

A field experiment was conducted on integrated weed management in suru sugarcane at PG Research Farm RCSM College of Agriculture, Kolhapur during 2024-2025 with eight treatments, which included three herbicide combinations viz. Tembotrione, Mesotrione + Atrazine (ready mix), 2,4-D Sodium salt + Metribuzin + Pyrazosulfuron- ethyl (ready mix) with one hand weeding were studied in randomized block design replicated thrice. In which weed free condition recorded highest yield (140.52 t ha-1) and among herbicidal treatments PoE application of 2,4-D Sodium salt (440 WG) + Metribuzin (350 WG) + Pyrazosulfuron- ethyl (10 WG) (ready mix) @ 3 kg a.i. ha⁻¹ at 15-20 DAP fb hand weeding at 60 DAP observed highest number of tiller (103.5 thousand ha-1), cane height (347.4 cm), millable cane number (83.33 thousand ha-1), girth (11.21 cm), dry matter accumulation (519.9 g plant-1), number of internodes (17.43 cane-1), length of internode cane-1 (11.84 cm) and cane yield (135.83 t ha-1).
