“…However significantly the lowest seed and stover yields were recorded in weedy situations due to excessive weed infestations. These findings agree with those of Tiwari et al [22] and Harisha et al [23]. All the weed management practices did not differ significantly among themselves with respect to seed protein content.…”

A field experiment was conducted at Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand, Gujarat, India during summer season of the year 2022 to study the “Efficacy of herbicides against complex weed flora and yield of summer blackgram (Vigna mungo L.)”. Experiment comprised of ten different weed management treatments, viz. pre-emergence application of pendimethalin (30% EC) 750 g/ha (T1), oxyfluorfen (23.5% EC) 117.5 g/ha (T2), pyroxasulfone (85% w/w WG) 127.5 g/ha (T3), diclosulam (84% WDG) + pendimethalin (30% EC) (tank mix) 21.0+750 g/ha (T4), pendimethalin (30%) + imazethapyr (2% SL) EC (pre-mix) 800 g/ha (T5), PoE application of imazethapyr (35%) + imazamox (35%) WG (pre-mix) 70 g/ha (T6), quizalofop ethyl 7.5% + imazethapyr 15% (w/w EC) (pre mix) 112.5 g/ha (T7), propaquizafop (2.5%) + imazethapyr (3.75%) ME (pre-mix) 125 g/ha (T8), IC fb HW at 20 and 40 DAS (T9) and weedy check (T10) were laid out in randomized block design with four replication. Results revealed that pre-emergence application of pendimethalin + imazethapyr 800 g/ha PE followed by IC fb HW at 20 and 40 DAS registered lower density and dry weight of weed, higher weed control efficiency, yield attributes and yield of black gram. While maximum net return (₹ 40324/ha) and BC ratio (2.62) were under pre-emergence application of pendimethalin (30%) + imazethapyr (2% SL) EC (pre-mix) 800 g/ha (T5) over rest of the treatments.
