Abstract: The present investigation was conducted during rabi season of 2018-19 and 2019-20 at Medicinal Plants Research and Development Centre (MRDC) of G. B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar (Uttarakhand) India, to study the effect of residual fertility of sweet basil (Ocimum basilicum) crop on yield of succeeding mustard crop. The experimental soil was sandy clay loam in texture, neutral in reaction, medium in organic carbon, low in available nitrogen and high in available phosphorus, exchangeable potassium and available sulphur. After the harvest of sweet basil crop mustard crop was grown on residual fertility of basil crop with different varieties (Kranti, PR 20 and NRCHB 101) as main plot treatment and residual fertility of basil crop as sub plot treatments with one recommended dose of fertilizer (RDF) which replaced RDF of basil crop. Succeeding mustard crop, gave higher number of siliquae per plant, number of seeds per siliqua, length of siliqua, 1000 seed weight, seed yield and stover yield with the application of recommended dose of fertilizers which was on a par with the residual fertility level of 120 kg N+60 kg P2O5+40 kg K2O+40 kg S ha-1 of basil. On the basis of present study, it can be inferred that the yield of mustard variety NRCHB 101 was found higher compared to Kranti and PR 20 when grown on residual fertility level of 120 kg N+60 kg P2O5+40 kg K2O+40 kg S ha-1 of sweet basil.
