An experiment was conducted at All India Co-ordinated Research Project for Dryland Agriculture, Gandhi Krishi Vignana Kendra, Bangalore to assess the effect of custard apple (CA) based Agri-Horticulture system on yield of different crops and soil properties during kharif 2017. The experiment consisted of 15 treatments viz., T₁:CA+finger millet, T₂:CA+fodder maize, T₃:CA+field bean, T₄:CA+niger, T₅:CA+chilli, T₆:CA+cowpea, T₇:CA+foxtail millet, T₈: Finger millet alone, T₉: Fodder maize alone, T₁₀: Field bean alone, T₁₁: Niger alone, T₁₂:Chilli alone, T₁₃: Cowpea alone, T₁₄: Foxtail millet alone and T₁₅: Custard apple alone, replicated thrice using randomised block design.

The results revealed that all crops recorded higher yield in sole treatments compared to their respective intercropping systems. The yield of CA was higher under sole treatment (4477.34 kg ha^-1) and lower yields in CA+fodder maize treatment (3800.83 kg ha^-1). The custard apple equivalent yield (CEY) was found higher in CA+finger millet treatment (807.14 kg ha^-1) followed by CA+chilli treatment (715.01 kg ha^-1) and lowest was observed under CA+foxtail millet (132.51 kg ha^-1) treatment. Soil available nutrients like nitrogen, phosphorus and potassium were recorder higher under CA+cowpea (262.50, 80.91 and 176.22 kg ha^-1, respectively) treatment followed by CA+field bean (258.95, 78.70, 171.39 kg ha^-1, respectively). The lowest available nutrients were recorded under fodder maize alone treatment.
