Effect of different liquid organic manures on nutrient content, uptake and quality parameters of Radish (Raphanus sativus L.) Cv. Arka Nishanth

In view of the cost effectiveness and eco-friendly characteristics of the organic manures, a field experiment was conducted at organic farming block of Zonal Agricultural Research Station, V. C. Farm, Mandya during late Kharif 2020 to study the effect of liquid organic manures on nutrient content, uptake and quality parameters of radish. The experiment was laid out in Randomized Complete Block Design with nine treatments and replicated thrice. The treatments comprised of soil application of Panchagavya and Jeevamrutha at the time of sowing and 30 DAS along with the application of 50% and 75% RDN through FYM and 100% RDN through FYM only as standard check. The result of present investigation indicated that significantly higher total N (98.96 kg ha^-1), P (9.08 kg ha^-1), K (105.12 kg ha^-1), secondary nutrient uptake, quality parameters of radish both in root and shoot viz., protein (0.72 and 2.06 g 100g^-1), ash (1.74 and 0.76%), total phenols (53.12 and 88.67 mg GAE g⁻¹), total acidity (0.71 and 1.83%), TSS (5.52 and 6.87 ^oBrix), ascorbic acid (21.52 and 33.02 mg 100g^-1) and glucosinolate content (60.57 and 20.88 µmol g^-1) were found higher in T₉ (75% RDN through FYM +two times application of Panchagavya) and was on par with application of 75% RDN through FYM +two times application of Jeevamrutha (T₅), whereas Nitrate-N content was found to be nonsignificant. Thus, organic manures play a major role in improving quality of radish.
