A field experiment entitled “Response of fly ash and nitrogen on production of toria (Brassica campestris var. toria)” was conducted during rabi 2018-19 at Research Farm, Guru Kashi University, Talwandi Sabo, Bathinda (Punjab). The experiment was laid out in split plot design comprising three fly ash levels viz., control (0 t/ha), 5 and 10 t/ha in main plots and four levels of nitrogen viz., 0, 37.5, 62.5 and 87.5 kg N/ha in sub plots. The results showed that the highest plant growth viz., plant height and leaf area index, number of primary branches/plant and number of secondary branches/plant and yield attributing characters viz., number of siliquae/plant, siliquae length, and 1000-seed weight and stover yield was recorded in fly ash @ 10 t/ha which was significantly higher over the control and fly ash @ 5 t/ha. Fly ash @ 10t/ha resulted in 11.5 and 5.51% higher seed yield than control and fly ash @ 5 t/ha, respectively. Increasing nitrogen levels increased the plant height, leaf area index, number of primary branches and number of secondary branches significantly up to 87.5 kg N/ha. Significantly higher values of seed yield, stover yield and biomass yield were obtained in nitrogen @ 87.5 kg/ha than 0, 37.5 and 62.5 kg/ha. Nitrogen @ 87.5 kg N/ha recorded 39.2, 17.6 and 2.8% higher seed yield than control, 37.5 and 62.5 kg N/ha, respectively. The highest seed yield (12.68 q/ha) was recorded in fly ash @ 10 t/ha with N @ 35 kg/ha.
