An investigation was carried out at ICAR-National Research Centre on Seed Spices, Ajmer, Rajasthan during Rabi season 2016-17 to ascertain the suitable sowing date, fertilizers doses and weedicide for quality production of nigella variety AN-1. Result illustrated that significantly higher plant height (44.0 cm), per plant primary branches (6.6), secondary branches (8.5), days taken to 50% flowering (77.9), seed yield (778.8 kg ha-1), straw yield (1484.0 kg/ha) and biological yield (2262.9 kg ha-1) were recorded in 1st November sown nigella crop over crop sown on 15th and 30th November. Irrespective of sowing dates, the maximum plant height (44.9 cm), per plant primary branches (6.0), secondary branches (7.4), days taken to 50% flowering (74.8), seed yield (677.2 kg ha-1), straw yield (1367.2 kg/ha) and biological yield (2044.4 kg ha-1) were recorded under the application of NPK level (F2) 40:40:20 kg ha-1. The pre-emergence application of oxadiargyl @ 75g a.i. ha-1 provided more plant height (43.0cm), per plant primary branches (5.9), secondary branches (7.1), days taken to 50% flowering (68.0), weed counts (18.0 and 24.3 weeds/m2 area) at 30 and 60 DAS, respectively, seed yield (633.5 kg ha-1), straw yield (1386.1) and biological yield (2019.7 kg ha-1). On the basis of cumulative effect of the treatment combinations, D1xF2xW2 given maximum plant height (46.4 cm), number of primary and secondary branches (7.2 and 10.3), siliqua per plant (18.9), whereas maximum seed yield (922.2 kg ha-1), gross return (Rs.167440 ha-1), net return (Rs. 122900 ha-1) and BCR (3.76) were recorded in treatment combination D1 x F3 x W1.
