Abstract: The experiment was conducted at Regional Agricultural Research Station, Anakapalle, Andhra Pradesh on the sugarcane seed crop for two consecutive years during 2019-20 and 2020-21. The experiment was designed in a splitplot layout, with the treatments, i.e, control, biofertilizer mixture, trash mulching with bio-decomposers and application of different rates and timings of nitrogen and potassium were allotted to sub plot treatments and were replicated thrice. In both the years of experimentation, quality parameters of seedcane were not influenced by organic sources, however the sub plot treatments showed significant influence only on moisture percent, reducing sugars percent, germinability and seedling vigour index (SVI). The seedcane grown with the application of 125% STBNK alone at 45 days interval recorded significantly higher moisture percentage, reducing sugars percentage, germinability and SVI over 75 % STBNK (S1 and S2), it was statistically comparable with 125% STBNK applied at 30 days interval + additional dose of 25% recommended K at one month before harvesting, 100% STBNK alone applied at 45 days interval and 100% STBNK applied at 30 days interval + additional dose of 25% recommended K at one month before harvesting.
