The soil of the experimental plot was loamy sand in texture, low in available nitrogen (138.56 kg/ha), medium in available phosphorus (44.42 kg/ha) and high in available potassium (281 kg/ha) with slightly alkaline soil with pH of 7.50. There were nine treatment combinations comprising of three row spacings (22.5 cm, 30 cm and 45 cm) and three varieties (Neelam, T 397 and Pusa 3) were tested in a split plot design. Significantly the highest plant population (44.33 and 43.70) was recorded at 30 DAS and at harvest with the row spacing of 22.5 cm (S1). Among spacing treatments, significantly the highest plant height (22.69, 39.65 and 56.64 cm, respectively) at 30, 60 DAS and at harvest was recorded under the row spacing of 22.5 cm (S1). Significantly the highest numbers of branches per plant (7.68), number of capsules per plant (53.44) and test weight (7.07 g) were observed under the row spacing of 45 cm (S3). Linseed sown at narrow row spacing of 22.5 cm (S1) produced significantly the highest seed (1307 kg/ha) and stover yield (2214 kg/ha). The maximum net realization (₹ 43713/ha) and benefit cost ratio (2.01) were recoded under the row spacing of 22.5 cm. Pusa 3 variety recorded significantly the highest plant height of 22.65, 39.66 and 55.52 cm at 30, 60 DAS and at harvest, respectively. Significantly higher number of branches per plant (7.55), number of pods per plant (52.12) and test weight (7.08 g) were recorded with Pusa 3 variety but it was remained at par with T 397 variety. Significantly higher seed yield (1291 kg/ha) was recorded under Pusa 3 variety however it was found at par with variety T 397 (1188 kg/ha). The variety Pusa 3 recorded significantly the highest stover yield (2335 kg/ha). The maximum net realization (₹ 44604/ha) and benefit cost ratio (2.08) were accured with the Pusa 3 variety. Based on the results of one year experimentation, it is concluded that linseed crop should be sown at row spacing of 22.5 cm for securing higher seed yield and net realization on loamy sand. Linseed varieties Pusa 3 and T 397 performed better over Neelam.EnglishThesis
