Abstract
An experiment was carried out on sandy loam soil at the Crop Research Centre 1 (CRC-1) ITM University Gwalior (M.P.) during the winter (rabi) seasons of 2024â2025 to examine how linseed (Linum usitatissimum L.) responded to intra-row spacing under different nitrogen (N) levels. 12 treatments in total, with 3 replications, 4 N levels (0, 75, 100, and 125 kg N/ha), and 3 intra-row spacings (22.5, 30 and 45 cm) were used in the split plot design (SPD). There were considerably more branches, a higher Leaf area index, more capsules per plant, more seed capsules per plant, and a greater Test Weight (g) when the rows were spaced 45 cm apart. In contrast, a 30-cm intra-row spacing was still better in terms of plant height, stover output, dry matter accumulation seed, and economics. Compared to 22.5 and 45 cm, the improvement in seed yield under 30 cm intra-row spacing was 31.6 and 12.7%, respectively. A N application of 125 kg N/ha produced noticeably higher plant height, branch count, leaf area index, and dry matter accumulation than other N levels. It also produced higher yield attributes, including seed and stover yield. However, in the Madhya Pradesh region of Gwalior, the linseed crop must be planted with 30 cm between rows and 100 kg of N/ha to increase net returns and benefit-cost ratio.
