Abstract:
At the Agricultural Research Station in Badnapur, an agronomic investigation was carried out to determine the economics of weed control and the effects of several post-emergence herbicides on crop development and yield in chickpea. The gross and net plot sizes of the experimental unit were 4.5 m × 5.0 m and 3.6 m x 4.8 m, respectively. The sowing process was completed on October 19, 2020, using the dibbling technique, which uses 45 cm x 10 cm spacing. Irrigation, fertilizer management, pest control, and seed treatment were implemented for every treatment in accordance with the guidelines. In the field investigation, nine treatments were used, including randomized block design (RBD) and post-emergence herbicides. 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, height of the plant, number of branches plant^-1, number of pods plant^-1, pod yield plant^-1(g), seed yield plant^-1 (g), seed index, seed yield (kg ha^-1), straw yield (kg ha^-1), biological yield (kg ha^-1), harvest index, gross monetary returns (Rs ha^-1), net monetary returns (Rs ha^-1) and benefit: cost ratio was found highest in (T₇) weed free check (Manual weed control/ Recommended practice) followed by (T₅) Quizalofop-p-ethyl 100 g a.i./ha 25 DAS.
