Weed dynamics and yield of transplanted finger millet (Eleusine coracana L. Gaertn) as influenced by different weed management practices under lateritic soil of Konkan

Abstract

The field experiment was conducted during kharif season of 2017 to investigate the, “Integrated weed management in kharif finger millet (Eleusine coracana L. Gaertn) under lateritic soil of Konkan” at Agronomy Farm, College of Agriculture, Dapoli, Dist. Ratnagiri (M.S.). The soil of experimental plot was sandy clay loam in texture, acidic in pH and medium in organic carbon content. It was low in available nitrogen, medium in available phosphorus and available potassium. The soil was leveled, well drained and uniform in depth. The treatments comprised of oxyfluorfen (PE) (T1), oxadiargyl (PE) (T2), oxyfluorfen (PE) fb HW at 30 DAT (T3), oxadiargyl (PE) fb HW at 30 DAT (T4), oxyfluorfen (PE) fb bispyribac sodium (POE) (T5), oxadiargyl (PE) fb bispyribac sodium (POE) (T6), oxyfluorfen (PE) fb metasulfuron methyl + chlorimuron-ethyl (POE) (T7), oxadiargyl (PE) fb metsulfuron-methyl+ chlorimuron-ethyl (POE) at 25 DAT (T8), Weed free check (T9), unweeded check (T10). During the course of present investigation, periodical growth observations, yield contributing characters and yield were recorded to evaluate the treatment effects. Weed intensity, weed control efficiency worked out. Results revealed that among all the treatments, treatment weed free check and among weedicide treatments, treatment oxyfluorfen (PE) @ 0.1 kg a.i. ha-1 fb HW at 30 DAT produced higher growth and yield attributes as compared to rest of the treatments under study.
