Effect of nitrogen and phosphorus on growth and yield of linseed (Linum usitatissimum L.)

Abstract

A field experiment was carried out during Rabi season of 2024-2025, at Crop Research Farm, Department of Agronomy at Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) on sandy loam soil with neutral soil reaction to investigate the “Effect of Nitrogen and Phosphorus on Growth and Yield of Linseed (Linum usitatissimum L.)”. The experiment was laid out in randomized block design (RBD) which consisted of nine treatments and replicated twenty-seven. There were two factors taken into consideration i.e. Nitrogen (40, 50, 60) and Phosphorus (20, 30, 40). Application of 60 kg/ha Nitrogen + 40 kg/ha Phosphorus (Treatment 9) recorded significantly higher plant height (93.20 cm), higher plant dry weight (11.56 g/plant), maximum number of capsules/plant (46.00), maximum number of seeds/capsule (8.73), higher seed yield (1.23 t/ha), and higher stover yield (2.61 t/ha), maximum gross return (INR 68076/ha), maximum net return (INR 44895/ha) and benefit-cost ratio (1.96).
