Abstract: The present investigation was carried out with the objective to study the effects of different doses of fertilisers on seed storability of the Indian mustard variety NRCHB-101. The field experiment was conducted during 2016-17 at the Agronomy Main Research Station, OUAT, Bhubaneswar laid out in a Factorial Randomized Block Design with three replications and twelve treatments i.e. three levels of nitrogen (N1=80, N2=100 and N3=120 kg/ha), two levels of phosphorus (P1=20 and P2=40 kg/ha) and two levels of potassium (K1=0 and K2=30 kg/ha). The freshly harvested dried seeds were subjected to accelerated aging process and the seed storability parameters viz. germination percentage, seedling length and vigour index were studied. Seed storability was found to be significantly affected by NPK fertiliser doses. After accelerated aging test, highest level of germination percentage, seedling length and vigour index were observed at N2 which was significantly higher than N3 and N1. Lower level of phosphorus (P1) showed higher germination percentage and lower seedling length, whereas the effect of phosphorus was non-significant on vigour index. Higher level of potassium (K2) showed high germination percentage, seedling length and vigour index. The combined interaction of N-P-K revealed that highest germination percentage, seedling length and vigour index were observed under N2P1K2, whereas lowest values were obtained at N3P1K1.
