Effect of Nitrogen and Sulphur on Yield and Quality of Linseed in an Acid Alfisol

Grain, straw and oil yield of linseed (Linum usitatissimum) increased significantly due to S application in a two-years field study on an acid Alfisol. Oil content and yield also increased due to N application although grain and straw yield showed receding trend with the medium dose of N and increased with the highest N application rate. With each increment in S level from 0 to 60 kg ha⁻¹, palmitic, stearic, oleic and linoleic acids decreased consistently to increase linolenic acid. However. N application did not follow any definite response pattern in this respect. An optimum S application rate with benefit: cost ratio has also been worked out.
