Effect of nitrogen phosphorus and sulphur application on yield, quality, uptake and economics of linseed (Linun usitatissimum L.)

In the current study was oriented to examine the growth, yield, quality, nutrient uptake and economics of linseed (Linun usitatissimum L.) under different levels of nitrogen, phosphorus and sulphur application. The investigation was done at the Instructional farm, N. M College of Agriculture, N. A. U., Navsari (Gujarat) on heavy black soil during the winter season of 2016-19. Variable involved in this study were three treatments of nitrogen (50,75and 100 kg N/ha), three levels of phosphorus (25 and 50 kg P2O5 /ha) and three levels of sulphur(10,20 and 40 kg S/ha) laid out in Factorial Randomized Block Design. Result revealed that individual year and pooled analysis of seed yield, stover yield were found significantly higher under the application of 100 kg N/ha (N3) which remained at pat with 75 kg N/ha (N2).Incase of phosphorus levels result was found statistically highest under P2 (50 kg P2O5/ ha).Application of (S3) 40 kg S/ha was statistically higher and which remained at par with (S2) 20 kg S/ha for seed and stover yield. Treatment effect was recorded significantly not differ in case of oil content present in seed. Interaction effects of treatments was recorded non significantl effect in all the parameters. Thus based on three years field experimentation, it is concluded that better yield, quality, nutrient uptake and net return of linseed can be gained by application N2 (75 Kg N/ha), P2 (50 kg P2O5 /ha) and S2 (20 kg S/ha)in south Gujarat.
