Abstract:
A field experiment was conducted in AICRP on vegetable crops, Orissa University of Agriculture and Technology, Bhubaneswar, Orissa, India, during Rabi Season of 2016-17 to study the effect of source of nutrient on growth, yield and quality of radish (Raphanus sativus L.) in radish – coriander cropping sequence. The experiment was laid out with 8 treatments by adopting Randomized Block Design replicated thrice. The treatment combinations 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 results revealed that significant variations for growth, yield and quality parameters in radish. Invariably 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 record significantly highest days to seed germination(4days), plant height(33.50cm), number of leaves plant^-1(10.47), leaf area (293.46cm²), length of leaves (26.69cm), length of root(15.24cm), root circumference (10.23cm), Average root weight (160.26g), Days taken to harvest of roots(54days),fresh weight of radish root(72.33g), dry weight of radish root (3.60g), root yield (296.28qha^-1), vitamin C (15.44mg/ 100g), reducing sugar(2.97%), non reducing sugar(16.78%), total sugar(18.95%) and T.S.S.(5.45^â—‹Brix). However, Conventional practices (Recommended FYM @ 20 tha^-1 + fertilizer @ 80:60:80 NPK kg ha^-1 +PP chemicals) + IIHR microbial consortium @ 12.5 kg ha^-1) record the similar result recorded at par. Thus, it may be concluded that the adoption of either 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 or conventional practices (Recommended FYM @ 20 tha^-1 + fertilizer @ 80:60:80 NPK kg ha^-1 +PP chemicals) + IIHR microbial consortium @ 12.5 kg ha^-1) may be recommended for better growth, yield and nutritional quality of radish in radish-coriander cropping sequence under Bhubaneswar condition.
