abstract
A field experiment was conducted during kharif seasons of 2022-23 and 2023-24 at college farm of N. M. College of Agriculture, Navsari Agricultural University, Navsari (Gujarat). The soils of experimental unit were clay in texture. The data was analyzed using standard statistical techniques. Among different weed management practices, the minimum grass, sedge and broad-leaved weed density were recorded under Weed free check (HW at 20, 40 and 60 DAS) (T₉) followed by Pendimethalin 30 EC 1000 g/ha PE fb HW at 30 and 60 DAS (T₁) during both years and pooled analysis. Similarly, Weed free check (HW at 20, 40 and 60 DAS) (T₉) was recorded minimum total weed density and weed dry weight. Whereas, higher weed control efficiency and lowest weed index were noticed under Weed free check (HW at 20, 40 and 60 DAS) (T₉). Nevertheless, herbicide efficiency index, weed management index, agronomic management index and integrated weed management index were recorded highest under Pendimethalin 30 EC 1000 g/ha PE fb HW at 30 and 60 DAS (T₁) followed by Pyrithiobac sodium 10 EC 75 g/ha PE fb HW at 30 and 60 DAS (T₃).
