ABSTRACT
The field experiment was conducted at Annamalai University experimental farm, Annamalinagar to study suitable production technologies to maximise yield parameters of sesame. The experiment was conducted in randomised block design with thirteen treatments and replicated thrice. The treatment comprises of control, recommended dose of NPK, organic matter, application of biofertilizer, micronutrients, clipping at (0+2) leaf stage and planofix spraying of 30 ppm at 45 DAS and 55 DAS with different combinations. Among the treatment T12 (Azospirillum seed treatment, RD of NPK, soil application of MnSO4 @ 5 kg ha-1, clipping at 0 + 2 leaf stage and planofix spraying of 30 ppm at 45 DAS and at 55 DAS) recorded maximum number of capsules per plant (85.56), number of seeds per capsule (68.62), seed yield (999.82 kg/ha), stover yield (2898.63 kg/ha) and harvest index percentage (25.64). Hence, application of Azospirillum as seed treatment, recommended dose of NPK, soil application of MnSO4 @ 5 kg ha-1, clipping at 0 + 2 leaf stage and planofix spraying of 30 ppm at 45 DAS and at 55 DAS found to be best production technologies to improve yield.
