Abstract:
A field experiment was conducted to study the effect of spacing and nitrogen management practices on productivity of flax and dual purpose linseed varieties at the Instructional-cum Research Farm, IGKV, Raipur (C. G.) during rabi 2021-22 & 2022-23 and the results obtained are discussed here on the basis of two years mean data. The recommended dose of fertilizer was taken 60:30:30 N, P₂O₅ and K₂O kg ha^-1 respectively. The experiment was laid out in split-split plot design with two replications consisted treatments of four varieties of linseed viz. V₁: RLC-148, V₂: JLS-95, V₃: JRF-2 and V₄: RLC-92, three spacing viz., S₁: 15 cm, S₂: 22.5 cm, S₃: 30 cm and three levels of nitrogen viz., N₁: 100% N, N₂: 150% N, N₃: 200% N. Data revealed that the highest value of yield attributes viz. number of capsules plant^-1, number of seeds capsule^-1, test weight (g plant^-1) and seed yield (q ha^-1) were recorded with variety JLS-95 (V₂₎, spacing 30 cm (S₃) and 200% N (N₃). However, stover yield (q ha^-1), fibre length (cm) and fibre yield (kg ha^-1) were highest with V₃ (JRF-3) along with treatment N₃ (200% N). Oil content (%) and oil yield (kg ha^-1) was highest in V₄ (RLC-92) with treatment S₃ (30 cm row spacing). The closer row spacing increased plant height along with fibre length, whereas increasing nitrogen application from an optimum level had negative impact on oil content of linseed.
