Effect of Integrated Nutrient Management on Yield, Quality and Economics of Linseed (Linum usitatissimum L.)

Abstract

A Field experiment was conducted during the Rabi season of 2023-24 at crop research centre-1 of ITM University Gwalior, (M.P.) India, to evaluate the “Effect of Integrated Nutrient Management on Yield, Quality and Economics of Linseed”. The experiment followed a Randomized block design (RBD) with three replications. The experiment consisting of ten treatments combinations viz., Control, RDF NPKS (60:40:30:40 kg ha-1 ), N (60 kg ha-1), NP (60:40 kg ha-1 ), NPK (60:40:30 kg ha-1 ), N (60 kg ha-1) + 5 t ha-1 FYM, NP (60:40 kg ha-1) + 5 t ha-1FYM, N (60 kg ha-1) + 2 t ha-1 Vermicompost, NP (60:40 kg ha-1 ) + 2 t ha-1 Vermicompost and N (60 kg ha-1 ) + 5 t ha-1FYM + 1 t ha-1Vermicompost. The soil of the experimental field was slightly alkaline in nature having pH 8.3, EC 0.35 dSm-1, low in organic carbon (0.35 %), available nitrogen (211 kg ha-1) and medium in available phosphorus (13.0 kg ha-1) and Potassium (247 kg ha-1). The results revealed that the application of 60kgN ha-1 with the 5 t ha-1 FYM and 1 t ha-1Vermicompost recorded higher yield and quality parameters of the linseed crop. Among the treatment, the highest net return (₹42644) and benefit cost ratio (1.71) was recorded with the treatment of T10 (60kgN ha-1 with the 5t ha-1 FYM and 1 t ha-1Vermicompost).
