Abstract: A field investigation was conducted during the 2018-19 to study “Evaluation of different doses of Farmyard manure and Intercropping Turmeric (Curcuma longa L.) under Mandarin (Citrus reticulata Blanco) based Agroforestry system.” at College of Horticulture and Forestry, Jhalawar (Rajasthan). Eleven years old plantations of mandarin (Citrus reticulata Blanco.) at 6 x 6 m spacing were used for intercropping of five varieties of Turmeric (Curcuma longa L.) as an intercrop viz. ‘Sugandham, Udaipur local, Gujrat Navsari Turmeric-1, Chittor local and Kesar planted at 30 x 45 cm were selected. The experiment was laid out in randomized block design with three replications and applied different doses of FYM (10, 15 and 20 t/ha). The significant result was found in respect of Curcumin content (%) of Turmeric and the maximum curcumin content was found in T₁₅ (3.31 %) followed by T₁₃ (3.22 %) where as higher benefit-cost ratio was found in T₁₃ (3.15) (Mandarin + Curcuma longa L.var. GNT-1 @ 20 tonne FYM/ha) followed by T₂₈ (3.02) (Curcuma longa L.var.GNT-1 Sole @ 20 tonne FYM/ha). Therefore GNT-1 and Kesar varieties of Turmeric are recommended as an intercrop among five varieties in Mandarin Orchard as well as a sole crop at the spacing of 30X45 cm with the application of 20 tonne/ha FYM in South-Eastern Rajasthan.
