Abstract: Field experiment on Radish-Coriander Cropping Sequence was conducted at the field site of AICRP on Vegetable Crops of O.U.A.T., Bhubaneswar, Odisha India during Rabi season of 2016-17 to find out a suitable combination of chemical fertilizers and organic manure for sustainable crop yield. The eight treatments schedules were T₁: Conventional practices (Recommended FYM @ 20 tha^-1 + fertilizer @ 80:60:80 NPK kg ha^-1 +PP chemicals), T₂: Vermicompost @ 12.5t ha^-1 (PP with organic methods), T₃: FYM @ 20t ha^-1 (PP with organic methods), T₄: T₁ + IIHR microbial consortium @ 12.5 kg ha^-1), T₅: T₂ + IIHR microbial consortium @ 12.5 kg ha^-1 (PP with organic methods), T₆: T₃ + IIHR microbial consortium @ 12.5 kg ha^-1 (PP with organic methods), T₇: Safe production (Recommended FYM @ 20t ha^-1 + fertilizer @ 80:60:80 NPK kg ha^-1 + PP with organic methods) + IIHR microbial consortium @ 12.5 kg ha^-1 and T₈: Azospirillium + PSB @ 4 kg ha^-1(Control).The treatments were arranged in Randomized Block Design with three replications. Results revealed that adoption of either safe production (T₇) or conventional practices (T₄) had significant positive influence on vegetative growth, viz; plant height (31.74-33.50cm), leaves plant^-1(10.27-10.47),yield and yield attributing parameters, viz; root length (15.24 - 15.67 cm), root circumference (9.69-10.23 cm) and average root weight (152.63 – 160.26g), radish root yield (23.55 – 24.00 kg plot^-1 and 290.72 – 296.28 q ha^-1). Similar trend was also observed in coriander when grown on residual fertility of succeeding crop, radish with significantly better influence on vegetative growth, viz; plant height (15.20-16.39 cm), leaves plant^-1(5.83-6.18). However, significantly highest leaf yield was observed in T₂ and T₆ (4.53-4.60 kg plot^-1 and 55.93-56.79 qha^-1).
