Effect of paddy stubble powder on germination percentage and growth of chilli seedlings under poly tunnel condition

An experiment was conducted to study the effect of paddy stubble powder on chilli germination percentage and growth and development of seedlings under poly tunnel conditions at Agricultural College, Aswaraopet, Professor Jayashankar Telangana State Agricultural University, in 2024. The experiment consisted of (12) twelve treatments laid out in a (CRD) completely randomized design replicated thrice. The treatments comprised of Paddy stubble (PS) powder (T₁), Cocopeat (T₂), FYM (T₃), Vermicompost (T₄), PS Powder + Vermicompost (90:10) (T₅), PS Powder + cocopeat (50:50) (T₆), PS Powder + Perlite (90:10) (T₇), PS Powder + Biocontrol agents (90:10) (T₈), PS Powder + BA + vermiculite + perlite (80:10:05:05) (T₉), PS Powder + FYM + Biocontrol agents (80:10:10) (T₁₀), PS powder + FYM + cocopeat (80:10:10) (T₁₁) and Vermiculite (T₁₂).Among various treatments, the highest germination %, root, and shoot length were recorded with the treatment combination of PS Powder + BA + vermiculite + perlite (80:10:05:05) (T₉) which was significantly superior to all other growing media.
