Abstract

A field study was conducted during the winter season (rabi) 201213 at Ludhiana, Punjab, to identify the phos- phorus-efficient genotypes of Indian mustard [Brassica juncea (L.) Czernj. & Cosson]. Application of 15 kg/ha of P O increased the seed yield by 6.8% and stover yield by 8.5% over the control, whereas the increase with 30 kg/ 2 5 ha of P O over 15 kg/ha of P O was non-significant. The increase in oil content and P uptake at maturity with suc- 2 5 2 5 cessive dose of phosphorus was also significant. Among genotypes, NRCHB 101 with the highest seed (1.91 t/ ha) and stover (7.29 t/ha) yields outyielded all the other tested genotypes by significant margin of 6.730.8% for seed yield and 9.030.9% for stover yield. Genotype NRCDR 2 registered significantly higher oil content (40.2%), while NRCHB 101 registered significantly higher total phosphorus uptake at maturity (21.52 kg/ha). Interactions between doses of phosphorus and genotypes for all the parameters were found non-significant.
