Study on Different Sources of Organic Manures in Comparison with RDF on Growth and Yield of Sorghum [Sorghum bicolor (L.) Moench]

A field experiment was conducted during the rabi season of 2022 at Karunya Institute Technology and Sciences, Division Agronomy, Coimbatore, to study different sources organic manures in comparison with RDF on growth yield sorghum (Sorghum bicolor (L.) Moench). The laid out a randomized block design eight treatments replicated thrice. treatment consisted T1 - Absolute control, T2 100% (Inorganic), T3 Vermicompost N equivalent basis, T4 Farmyard manure T5 50% + 50%, T6 T7 T8 25% 25%. Therefore from this results concluded that application (Inorganic) significantly recorded maximum plant height (228.76 cm), total dry matter production (13485 kg ha-1), leaf area index (LAI) (5.80), chlorophyll content (SPAD) (37.89), grain (3770 ha-1) straw (6600 respectively.
