摘要：Environmental pollution caused by leaching and gaseous emissions from chemical fertilizers ne-cessitates evluation and optimization of organic sources ofplant nutrition for soybean production un-der changing climate scenario. A field study was ex-ecuted to test different fertilization regimes includ-ing chemical fertilizers(CF)(80 kg N and 80 kg P>Os ha-'), sheep barn manure(SBM)(5161 kg ha ), cattle barn manure (CBM)(4878 kg ha'), liquid cattle barn manure(LCBM)(27580 kg ha-')and ver-micompost(VC)(4000 kg ha").The yield attributes, grain yield and fatty acid composition of soybean were taken as response variables in this investiga-tion. The experimental design was randomized com-plete block design with three replications. The re-sults revealed that SBM and CF recorded the tallest plants and first pod height respectively at both R1 and R5 growth stages. In addition, SBM remained superior for recording significantly higher leaf num-ber at R1 and R5 and node number at R5 stage along with maximum pod number and seeds per pod. The maximum 1000 grain weight and grain yield were exhibited by LCBM which was followed by SBM. In addition, CBM gave the highest protein content while LCBM recorded the maximum oil percentage along with linoleic, mysteric and behenic acid con-tents. Furthermore, LCBM outperformed other ferti-lization regimes in terms of palmitoleic, stearic, lin-olenic and arachidic acids percentages along with oleic: linoleic acid ratio.
