The present investigation aimed to find out the “Effect of Different Types of Organic Manures and Mulching on Growth and Yield of Carrot (Dacucs carota L.).” was conducted on carrot at Agricultural Research Farm, Suresh Gyan Vihar University, Mahal, Jagatpura, Jaipur (Rajasthan) during the rabi season 2023-24. The experiment was laid out in factorial randomized block design. Replicated thrice with 12 treatment combinations, comprising three level of organic manure, O₀-no manure, O₁- Cowdung (25 t/ha),and O₂- Vermicompost (1.5 t/ha) with four levels of organic mulching, M₀- no mulch, M₁ – Straw mulch, M₂- - Black polythene, M₃- Wood ash. The application of organic manure was found most effective improve growth and yield parameter like maximum plant height (18.79, 26.36 and 43.81 cm) was recorded at 30, 60 and harvest DAS, root length of 24.24 cm, root diameter of 3.89 cm, dry root weight 13.02%, maximum root weight 100.23 gm and the maximum root weight per plot 26.61 kg was recorded from O₂ (Vermicompost, 1.5 t/ha). Black polythene mulch were recorded on growth and yield of carrot, the maximum plant height i.e. 17.45, 25.06 and 42.10 cm was observed at 30, 60 and harvest, root length of 24.15 cm, root diameter (cm) of 3.88 cm, dry root weight 13.13%, highest root weight plant (93.28 g) and the highest root weight per plot (25.19 kg) was found from M₂ (black polythene mulch).
