Title : Mechanized weed management in Cluster bean (Cyamopsis tetragonoloba L.) under rainfed conditions

Abstract :

A field experiment was carried out at Regional Research Station, Bawal (Rewari), CCS Haryana Agricultural University, Hisar, Haryana (India) during kharif season 2018 to study the effect of mechanized weed management in rainfed cluster bean (Cyamopsis tetragonoloba L.). The major weeds in the field were Cyperus rotundus, Digera arvensis, Trianthema portulacastrum and Eragrostis spp. The weed density and dry matter accumulation of weeds was significantly reduced by mechanized weed control methods than manual. Higher weed control efficiency was recorded under T6 (94.1%) and T5 (90.9) over T1 (16.0 %) and T2 (2.45 %) respectively. Two simultaneous mechanized interculture (at 20 and 35 DAS) with power weeder (T6) and tractor drawn cultivator (T5) under row spacing of 60 cm were found superior to recommended manual weeding once either with kasola (T1) or wheel hand hoe (T2) performed at 27 DAS under 45 cm row spacing.
