Abstract: A field experiment was conducted in a well established mulberry garden with variety V-1 to study the comparative effect of fly ash fortified crop residue and municipal waste based vermicomposts on growth and yield of mulberry at Sericulture unit, Department of Agricultural Entomology, College of Agriculture, UAS, Raichur, Karnataka during 2018-19. The experimental plot was laid in randomized block design and nine treatments with three replications. Treatment wise 5, 10, 15% fly ash fortified crop residue and municipal waste vermicomposts was produced for application to mulberry garden @ 7.5 t /ha/year along with recommended dose of chemical fertilizer. Treatment wise vermicomposts was applied to mulberry garden 10 days after pruning and incorporated into soil and mulberry crop was raised for about 65 days and mulberry growth and yield was recorded. Among the treatments, mulberry growth and yield was significantly superior in T2 (Vermicompost produced from mixed crop residues along with fly ash fortification @ 10 % + recommended dose of chemical fertilizers) followed by T1 (Vermicomposts produced from mixed crop residues along with fly ash fortification @ 5% + recommended dose of chemical fertilizers). Significantly lower growth and yield parameters were recorded in control. The increase in yield might be due to supplementation of major and minor nutrients. This in turn might have enhanced chlorophyll synthesis and triggered the physiological activity of plants by producing required auxins which might have influenced meristematic activity, expansion of cell and formation of cell wall, cell division and differentiation leading to higher leaf yield, shoot height, leaf area and leaf yield of mulberry.
