Comparative analysis of different weedicides against various weed flora, crop growth and yield in wheat (Triticum aestivum L.)
Abstract: Mostly weeds are ubiquotous and repugnant in nature which competes with crops for water, nutrients and sunlight, so weed infestation is one of the major threats to crop. Present investigation was aimed to assess the impact of different weedicides for weed management in wheat crop under agro-climatic conditions of Faridabad. This experiment was conducted at Dayalpur, Mohna village of Faridabad. The experiment was carried out in a Randomised block design (RBD) with three replications. Different weedicides were used for weed management in wheat crop. These include application of 2, 4-D @ 750 g ai/ha, Pendimethalin @1.0 kg a i ha-1, Fenoxaprop ethyl @100 g a i ha-1, Clodinafop @ 60 g a i ha-1, Sulfosulfuron@25 g a i ha-1. For comparison among weedicides, control (weedy check) were also included. In each replication, six treatments of these five weedicides including control were taken. The significantly affected parameters were density and dry weight, weed control efficiency (%), weed index of weeds taken from sedges, grasses and BLW where statistical analysis showed that maximum weed control efficiency (84%) was recorded with 2, 4-D followed by Sulfosulfuron whereas minimum value (37%) was with control (weedy check). Similarly maximum number of tillers m–2 (250) was recorded for 2, 4-D followed by Sulfosulfuron and minimum (133) in control (weedy check). The herbicide 2, 4-D followed by Sulfosulfuron weedicide was applied at post emergence performed well and exhibited effectively weed control and better yield in wheat.
