Abstract Organic matter decomposition is beneficial to plant growth and development; thus, the integration of organic fertilizers appears to be a suitable option for saving chemical fertilizers and reducing environmental pollution. In this study, a two years field experiment was conducted at Agricultural Research Farm, SKRAU, Bikaner during rabi seasons of 2020–21 and 2021–22. The experiment comprising a total of 32 treatment combinations; eight sources of organics (M0-Control, M1 - FYM @ 20 t ha−1, M2 -Groundnut husk (GNH) @ 20 t ha−1, M3 -Wool waste (WW) @ 20 t ha−1, M4 -FYM @ 10 t ha−1 + GNH @ 10 t ha−1, M5 -WW @ 10 t ha−1 + GNH @ 10 t ha−1, M6 -WW @ 10 t ha−1 + FYM @ 10 t ha−1, and M7 -WW @ 6.67 t ha−1 + FYM @ 6.67 t ha−1 + GNH @ 6.67 t ha−1) and four fertilizer levels (F0-Control, F1-50% Recommended dose of fertilizer, F2-75% Recommended dose of fertilizer and F3-100% Recommended dose of fertilizer). In the two year experiment, it was observed that incorporation of wool waste @ 20 t ha−1 registered maximum growth, yield attributes and yield of garlic, significantly superior to all the rest treatments. On the other hand, among the fertilizer levels, application of 100% RDF i.e., 50 kg N, 60 kg P2O5 and 100 kg K2O recorded maximum growth, yield attributes and yield of garlic.
