Abstract:

An experiment was conducted at the Research Farm of Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu under irrigated conditions to assess the efficacy of different weed management practices on weed dynamics, nutrient removal and productivity of direct seeded basmati rice preceded by wheat in a crop sequence of wheat and rice. The most efficient weed control was provided by the application of Pendimethalin @ 1.0 kg/ha (PE) fb Bispyrebac @ 0.030 kg/ha (PoE) that resulted in highest Weed Control Efficiencies of 84.01 and 86.05 % favouring highest grain yields of 23.69 and 25.09 q/ha of direct seeded basmati rice correspondingly this treatment recorded maximum and minimum removal of nutrients by crop and weeds, respectively. Nutrient uptake by both crop and weeds was directly influenced by the relative efficacy of weed management treatments.


Keywords: Direct seeded basmati rice, Nutrient uptake, Weed management, Weed dynamics.
