Abstract:
At the Agricultural Research Station in Badnapur, a field experiment was conducted to assess the impact of various post-emergence herbicides on weeds in chickpea, (Cicer arietinum L). The experimental unit's gross and net plot sizes were 4.5 x 5.0 m and 3.6 x 4.8 m, respectively. On October 19, 2020, seeds were sown using the dibbling method, with 45 cm x 10 cm spacing. The recommendations for each treatment were followed when it came to seed treatment, pest control, irrigation, and fertilizer management. Post-emergence herbicides are one of the nine treatments in the randomized block design (RBD) field experiment. Treatment comprised of (T₁) Topramezone 20.6 g a.i./ha at 14 DAS, (T₂) Topramezone 20.6 g a.i./ha at 21 DAS, (T₃) Topramezone 25.7 g a.i./ha at 14 DAS, (T₄) Topramezone 25.7g a.i./ha at 21 DAS, (T₅) Quizalofop-p-ethyl 100 g a.i./ha 25 DAS, (T₆) Unweeded control, (T₇) Weed free check (Manual weed control/ Recommended practice), (T₈) Pendimethalin @ 0.75 kg a.i./ha (PE), (T₉) Fluazifop-p-butyl @ 1.0 kg a.i./ha 30 DAS. The results specified that, at 35 DAS highest weed control efficiency was recorded (74.04%) in (T₅) weed free plot followed by (T₄) Topramezone 25.7 g a.i./ha at 21 DAS (65.31%) and lowest weed control efficiency recorded in (T₉) Fluazifop-p-butyl @ 1.0 kg a.i./ha 30 DAS (33.74%).
