Abstract

The performance of 5 genotypes of Brassica juncea (L.) Czemj. & Coss.'CS 52','Kranti',' GJM 9056','RH 30'
and 'RH 8814' and I genotype of Brassica napus L. 'GSH l' under 4 nitrogen levels were studied for two consecutive
seasons at Hisar to assess the effect of nitrogen fertilization on phenological and physiological behaviour of Brassica
genotypes. The flower initiation, full bloom, siliquae formation and 50 % pod browning were significantly delayed at
80 kg N/ha compared to 40 kg N/ha in 'GJM 9056' genotype. The trend in other genotypes followed a descending order
'RH 8814','CS 52','Kranti', 'RR 30','GSH I' in flower initiation and remained up to 50% pod browning. The
Brassica juncea genotypes had better physiological parameters viz leaf area index and crop growth rate compared with
the Brassica napus genotype. Leaf area index increased significantly with successive increase in N levels up to 60 kg
N/ha while crop growth rate increased up to application of 80 kg N/ha.
