A field experiment was conducted in 2014 at farmer’s field in Varagoorpettai village, Cuddalore, Tamilnadu to study the effect of integrated nutrient management on growth and yield of radish (Raphanus sativus L.) cv. pusa chetki. The experiment was laid out in Randomized Block Design with three replications and ten treatments. The treatment combination consisted of a organic manures (FYM and Vermicompost) Bio-fertilizer (Azospirillum) and Plant bio regulator (Humic acid). The treatment details viz., T1 - FYM @ 17.5 t ha-1+ Azospirillum @ 5 kg ha-1 + Humic acid @ 0.1 % ha-1, T2 - FYM @ 17.5 t ha-1+ Azospirillum @ 5 kg ha-1 + Humic acid @ 0.2 % ha-1, T3 - FYM @ 25 t ha-1 + Azospirillum @ 5 kg ha-1 + Humic acid @ 0.1 % ha-1, T4 - FYM @ 25 t ha-1+ Azospirillum @ 5 kg ha-1 + Humic acid @ 0.2 % ha-1, T5 - Vermicompost 10 t ha-1 + Azospirillum @ 5 kg ha-1 + Humic acid @ 0.1 % ha-1, T6 - Vermicompost 10 t ha-1 + Azospirillum @ 5 kg ha-1 + Humic acid @ 0.2 % ha-1, T7 -Vermicompost 12.5 t ha-1 + Azospirillum @ 5 kg ha-1 + Humic acid @ 0.1 % ha-1, T8 -Vermicompost 12.5 t ha-1 + Azospirillum @ 5 kg ha-1 + Humic acid @ 0.2 %, T9 – Recommended dose of NPK @ 80:40: 80 kg ha-1 and T10 - Absolute Control. Among the treatment significantly influenced on application of Vermicompost 12.5 t ha-1 + Azospirillum @ 5 kg ha-1 + Humic acid @ 0.2 % ha-1 (T8) resulted in maximum values of growth and yield attributes viz., days taken for germination (3.12), shoot length (43.56 cm), number of leaves per plant (14.68 DAS), leaf area (185.86), shoot weight (56.23 g), crop dry matter production (26.13 g). root length (15.63 cm), root girth (3.11 cm), root weight (161.59 g) and root yield per plot (4.09 kg), ascorbic acid (30.18 mg 100 g-1), calcium content (57.91 mg 100 g-1) and fibber content (1.07 mg 100 g-1) quality characters. Application of Vermicompost 12.5 t ha-1 + Azospirillum @ 5 kg ha-1 + Humic acid @ 0.2 % ha-1 is recommended to get higher yield in radish.
