Effect of nitrogen and weed management on weed control efficiency and yield of fodder turnip

A field experiment was conducted at Forage Research and Management Centre, NDRI, Karnal during rabi season in 2013–14 to study the effect ofnitrogen application and weed management on growth andyield of fodder turnip (Brassica compestris var. rapa) with four levels of nitrogen (0, 50, 100, and 150 kg N/ha) and four weed management practices (pendimethalin @ 1.0 kg a.i./ha, hand weeding, isoproturon @ 0.75 kg a.i./ha and weedy check) in split plot design. Among the nitrogen treatments150kg nitrogen/hagavethehighestgrowth, yield andbetterqualityoffodder turnip. Application of pendimethalin @1.0 kg a.i. proved better in terms of growth and yield of turnip. Weed control efficiency was 65% with 150 kg N/ha and 83.23% with pendimethalin 1.0 kg a.i./ha.
