abstract
A field experiment was conducted during kharif season, 2022 at Research Farm, School of Agriculture, Suresh Gyan Vihar University, Jaipur (Rajasthan) to study the “Effect pre- emergence and post- emergence harbicides for weed management in mungbean [Vigna radiata (L.) Wilczek]”. The experiment was laid out in Randomized Block Design with ten treatments each replicated thrice based on one year of experimentation (T1: Pendimethalin 30 EC at 0.75 kg a.i ha-1 PE, T2: Pendimethalin 30 EC at 0.75 kg a.i ha-1 PE fb handweeding at 30 DAS, T3: Pendimethalin 30 EC at 0.75 kg a.i ha-1 PE fb Fenoxaprop–p-ethyl 9 EC at 70 g a.i ha-1 POE, T4: Pendimethalin 30 EC at 0.75 kg a.i ha-1 PE fb Imazethapyr 10 SC at 100 g a.i. ha-1 POE, T5: Metribuzin 70 WP at 0.5 kg a.i ha-1 PE, T6: Metribuzin 70 WP at 0.5 kg a.i ha-1 PE fb handweeding at 30 DAS, T7: Metribuzin 70 WP at 0.5 kg a.i ha-1 PE fb Fenoxaprop–p-ethyl 9 EC at 70 g a.i ha-1 POE, T8: Metribuzin 70 WP at 0.5 kg a.i ha-1 PE fb Imazethapyr 10 SC at 100 g a.i. ha-1 POE, T9: Weed free and T10: Weedy check each replicated thrice. The lowest weed population, dry weight, highest percent weed control efficiency and productivity of mungbean were recorded by the weed free treatment. Among all the herbicidal treatments, the lowest weeds count, weeds dry weight and highest percent weed control efficiency; high growth and productivity of mungbean were recorded under treatment T4: Pendimethalin 30 EC at 0.75 kg a.i ha-1 PE fb Imazethapyr 10 SC at 100 g a.i. ha-1 POE which can be recommended to the farmer.
