Abstract: Field experiment was conducted at Agricultural College and Research Institute, Killikulam during rabi season (October 2019 - January 2020) to find out the suitable organic manures and level of fertilizers on the growth and yield of dual purpose K12 sorghum (Sorghum bicolor) under irrigated condition. The experiment was laid out in split plot design and replicated thrice. The main plot consists of four different organic manures namely FYM @12.5 t ha-1, poultry manure @ 5.0 t ha-1, vermicompost @5.0 t ha-1 and composted pressmud @ 3.0 t ha-1. In sub plots 75%, 100%, 125% recommended dose of fertilizers was applied along with absolute control (without fertilizer). Observation on plant growth parameters like plant height and dry matter production was recorded at 30, 60 DAS and at harvest. The grain yield and stover yield was also recorded. The experimental result shows that application of poultry manure @ 5 t ha-1 with 125% recommended dose of NPK recorded significantly higher plant height (307.3cm), dry matter production (19635 kg ha-1), grain (4589 kg ha-1) and stover yield (15711 kg ha-1).
