Linseed (Linum usitatissiumum L.) is an important oilseed crop of India, locally known as Alesi and Tessi. It has been cultivated since ancient times for its oil-rich seeds and flax (fiber). It is a member of the family Linaceae. It is an annual plant with blue flowers that yields tiny linseed that ranges in colour from reddish brown to golden yellow. Madhya Pradesh, Uttar Pradesh, Maharashtra, Chhattisgarh, Bihar, and Jharkhand are the primary Indian states where linseed is grown. An experiment entitled on Effect of Phosphorous and Sulphur on growth and yield of Linseed (Linum usitatissiumum L.) was conducted during Rabi season of 2024 at Crop Research Farm, Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom University of Agriculture, Technology and Science, Prayagraj (U.P.) India. Three levels of phosphorus (25, 35, and 45 kg/ha) and Sulphur (15, 20, and 30 kg/ha) were used in the various treatments, along with RDF. The sandy loamy soil in the experimental plot had a pH of (7.3), was almost neutral in soil reaction, and had a low organic carbon content of (0.45%), potassium (243.8 kg/ha) and available phosphorus (27.4 kg/ha) nitrogen (239.5 kg/ha). The experiment was laid out in a Randomized Block Design with ten treatments which have replicated thrice. The results revealed that significantly higher growth attributes of Linseed at 80 DAS viz., plant height (51.63 cm), dry weight (3.52 g), Capsule /plant (30.88), seed/Capsule (8.11), test weight (9.61), grain yield (945.82 kg/ha) and stover yield (1560.67) were recorded in T₇ (Phosphorus 45 kg/ha + Sulphur 15 kg/ha) compared to other treatments and Maximum gross return (INR 95030.92/ha), net return (INR 64952.92/ha) and B:C ratio (2.16) were also recorded in T₆ (Phosphorus 45 kg/ha + Sulphur 15 kg/ha). It was determined that applying phosphorus and Sulphur improves linseed development and yield, as evidenced by the highest test weight, grain yield, stover yield, gross return, net return, and benefit cost ratio, as well as the fact that it is financially advantageous.
