A field experiment was carried out at Kangra during the winter (rab~) seasons of 1996-97 to 1998-99 to find out the suitable high-yielding variety of gobhi sarson (Brassica napus subsp. oleifera var annua) variety and its nitro- gen requirement under mid-hill conditions of north-western Himalayas. The treatments consisted of 4 gobhi sarson varieties ('Hyola 401', 'Neelam', 'Sheetal' and 'GSL 1') tested against 'Kranti' (check) of Indian mustard [Brassica juncea (L.) Czernj. & Cosson] at 3 nitrogen levels (60, 90 and 120 kg Nlha). Among different yield attributes, plant -. and seedslsiliqua were highest in gobhi sarson hybrid 'Hyola 401', while 1,000-seed weight was highest in Indian mustard 'Kranti'. In spite of poor yield due to inferior quality seed during the third year, 'Hyola 401' gave signifi- cantly highest seed yield on pooled basis.The seed yield also increased with increasing nitrogen levels, being sig- nificantly highest with the application of 120 kg N/ha. The nutrient uptake followed the same trend as that of seed yield with highest uptake values recorded fromCHyola 401' and with the application of 120 kg Nlha.
