Abstract
Vermicompost, recommended inorganic fertiliser, vermiwash and their combinations were used in the present study to know their impact on the germination, growth, yield, oil content and nutritional status in seeds of two varieties of Linum usitatissimum L. LC-54 and LC-2063. Eight treatments, in 48 plots with three replicates, were studied and compared with control. Application of vermicompost enhanced growth and yield in both varieties of Linum. Vermicompost modulated the ratio of ω-3 and ω-6 fatty acids in seeds of Linseed. Growing degree days (GDD) indicated the significantly shortened of crop life cycle with vermiwash. Vermiwash particularly increased the yield indices. Fatty acid profile through GC-FID showed the increase in polyunsaturated fatty acids (ƩPUFA), monounsaturated fatty acids (ƩMUFA) and saturated fatty acids (ƩSFA) with Integrated Nutrient Management (INM). Different effects on nutritional status of LC-54 and LC-2063 seeds can be attributed to their unique genotypes. INM proved to be nutritionally balanced strategy with enhanced yield leading to better soil health. INM can be hypothesised as a transitional step to the organic agriculture after the green revolution, when compared with recommended inorganic fertiliser treatment and control. In terms of oil yield, highest oil content 34.85% and 33.67% was obtained with Integrated Nutrient Management in both the varieties, whereas treatments with vermicompost and vermiwash produced modulated and most suited ratio of omega-3 and omega-6 in Linseed seeds.
