Studies on effect of integrated nutrient management on growth and yield attributes in radish (Raphanus sativus L.) and its residual effect in coriander (Coriandrum Sativum L.) in radish-coriander cropping sequence

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).
