Field experiment was laid out during two consecutive crop years of 1987–88 and 1988–89 on a sandy loam soil to study the response of linseed (Linum usitatissimum L.) crop to applied nitrogen. phosphorus and sulphur. Doses of N were 0, 40 and 80 kg ha−1. The doses of P and S were 0, 25 and 50 kg P2O5 furl and 0, 30 and 60 kg S ha−1, respectively. The seed yield and protein content in seed of linseed significantly increased with increasing levels of applied N, P and S. Nitrogen application increased seed yield by 37.4 and 39.0 per cent, while decreased the oil content by 3.33 and 2.69 per cent in the year 1987–88 and 1988–89, respectively over control. Phosphorus application increased the seed yield and oil content by 17.3, 14.1 and 3.91 and 3.93 per cent and sulphur application increased yield and oil content by 10.2, 11.6 and 6.46 and 6.60 per cent in both the years, respectively over control. Significant responses of linseed to applied nutrients were found up to 80 kg N. 50 kg P2O5 and 30 kg S ha−1.
