Effect of fertility levels on growth and quality parameters of linseed (Linum usitatissium L.) under different irrigation levels

A field experiment was conducted during 2024-25 at Agronomy Research Farm, School of Agricultural Sciences, Jaipur National University, Jaipur, Rajasthan to evaluate the “Effect of fertility levels on growth, yield and quality of linseed (Linum usitatissimum L.) under different irrigation levels. The experiment was laid out in split plot design with three replications. The experiment comprised four levels of irrigation viz.; control, one irrigation, two irrigation and three irrigation as main plot and three levels of fertility viz; 50% RDF, 75% RDF and 100% RDF as sub plot. The significantly higher growth parameters viz., plant height, number of branches, dry matter accumulation (DMA), crop growth rate (CGR) and relative growth rate (RGR) and quality parameters i.e. the maximum oil content and oil yield (501.68 kg ha^-1), protein content and yield (287.16 kg ha^-1) and maximum N, P, K and S content and their uptake by linseed were obtained with the application of three irrigation followed by two irrigations. However, Among the fertility level, the application of 100% RDF gave significantly higher growth parameters viz., plant height, number of branches plant^-1, DMA, CGR and RGR and quality parameters i.e. the maximum oil content and oil yield (437.66 kg ha^-1), protein content and yield (232.54 kg ha^-1) and maximum N, P, K and S content and their uptake by linseed and it was followed by 75% RDF.
