Abstract:
Keeping above view in mind the present investigation entitled “Effect of various broad spectrum herbicide combinations on productivity of wheat (Triticum aestivum L.)” was carried out at “KVK Farm, IGKV, Raipur (C.G.) during Rabi season of 2020-21. Variety of Wheat under experimentation was CG AMBER which has special gluten quality. The crop was grown under irrigated condition after harvest of rice. The experiment was laid out in randomize complete block design with 3 replications and 10 treatments. The treatments consisted of different weed management practices in wheat Sulfosulfuron (75 WP) + Metsulfuron-methyl (5 WP) (pre-mix) (T1), Mesosulfuron-methyl (3WG) + Iodosulfuron-methyl (0.6WG) (pre-mix) (T2), Sulfosulfuron (75WP) + Metribuzine (70 WP) (tank mix) (T3), Clodinafop-propargyl (15WP)+ Metribuzine (70WP) (tank mix) (T4), Clodinafop-propargyl (15WP) + Metsufuron-methyl (1WP) (pre-mix) (T5), Pinoxaden (5.1WP)+ Metsulfuron-methyl (20WP) (tank Mix) (T6), two hand weedings at 20 and 40 DAS (T7), Inter row mechanical weeding + hand weeding intra row at 20 DAS (T8), two hand weedings at 20 and 40 DAS + mechanical weeding by hand hoe at 25 DAS (T9), Weedy check (T10). The wheat crop was supplied with the recommended dose of fertilizer @ 120:60:40 N: P: K kg ha-1. Soil of the experimental field soil was sandy loam (Inceptisol) with low N, medium P and high K content. The result revealed that among different weed management practices. Two hand weedings at 20 and 40 DAS + mechanical weeding by hand hoe at 25 DAS produced the maximum value of growth, yield attributes, grain yield (42.72 q ha-1) and straw yield (56.10 q ha-1). However, grain yield of wheat was statically at par with two hand weedings at 20 and 40 DAS (T7), Mesosulfuron-methyl + iodosulfuron methyl (12g+2.4g ha-1 POE) (pre-mix) (T2) at 30,60.90 and 120 DAS over weedy check plot. The higher cultivation cost (45358 ₹ ha-1), gross monetary returns (95628 ₹ ha-1) were noticed with two hand weedings at 20 and 40 DAS + mechanical weeding by hand hoe at 25 DAS (T9) being comparable to Two hand weedings at 20 and 40 DAS (T7). Maximum net returns (59080 ₹ ha-1) and higher B: C (2:73) ratio was noticed under (Mesosulfuron-methyl +iodosulfuron methyl) (12g+2.4g ha-1 POE) (pre-mix) (T2) over weedy check plot.
