Effect of different levels of phosphorus on seed and oil yield of two genotypes of linseed (Linum usitatissimum L.)

A field trial to investigate the effect of different levels of phosphorus i.e. 0, 30, 60 and 90 kg ha' on the growth and yield of two genotypes of linseed namely 'Chandni' and 'LS-49' was carried out at the Agronomic Research Area, University of Agriculture, Faisalabad. The number of capsules per plant, number of seeds per plant, 1000-seed weight, seed yield and oil contents were influenced significantly by the application of phosphorus. The maximum mean seed yield of 1189.73 kg ha" was obtained with the application of 90 kg P20S ha-' but was at par with 60 kg P 2 0 S ha'. The ~enotypes LS-49 produced significantly higher mean seed yield (1697.48 kg ha') than Chandni (1169.77 kg ha).
