A field experiment was conduced during the winter season of 2002–03 and 2003–04, to find out the effect of nitrogen levels and its split application on yield attributes and yield of Indian mustard [Brassica juncea (L.) Czernj. & Cosson]. Application of increasing levels of nitrogen from 40 to 100 kg/ha significantly enhanced siliquae/plant, seeds/siliqua, siliqua length, test weight, seed yield and NPK uptake of Indian mustard. However, significant increase in stover and biological yields was recorded up to 120 kg N/ha. Further, application of one-third N as basal + one-third at first irrigation + one-third at second irrigation being statistically at par with half basal + one-fourth at first irrigation + one-fourth at second irrigation brought a substantial improvement in siliquae/plant, seeds/siliqua, siliqua length, test weight, seed, stover and biological yield and NPK uptake compared to 2 equal splits, viz. half at basal + half at first irrigation, DAP basal + half of rest at first irrigation + half rest at second irrigation and 100% basal.
