Doubling the farmer’s income through intercropping turmeric (Curcuma longa L.) under mandarin based agroforestry system in South-Eastern Rajasthan

A field experiment was conducted during the June 2017 to March 2018 to study “Intercropping Turmeric (Curcuma longa L.) Under Mandarin based Agroforestry System in South-Eastern Rajasthan” at the Instructional farm, Fruit Science, College of Horticulture and Forestry, Jhalawar, Agricultural University, Kota (Rajasthan). Six years old plantations of mandarin (Citrus reticulata Blanco.) at 6 x 6m spacing were used for intercropping of five varieties of Turmeric (Curcuma longa L.) as an intercrop viz. ‘Kesar, Sugandham, Gujarat Navsari Turmeric-1, Chittor local and Udaipur local’ planted at 30 x 45 cm were selected for the present study laid out in randomized block design with three replications. Highest benefit cost ratio was found in T3 (Mandarin + Curcuma longa L. var. GNT-1) (2.92) followed by T1 (Mandarin + Curcuma longa L. var. Sugandham) (2.70). Higher benefit cost ratio also revealed that GNT-1 and Sugandham varieties of Turmeric should be grown under Mandarin based Agroforestry system in South-Eastern Rajasthan as an intercrop with the spacing of 30 x 45 cm.
