Abstract: Field experiment was conducted at Annamalai University Experimental Farm, Department of Agronomy, Annamalai Nagar to find out practically sustainable maize based intercropping system for aberrant rainfall condition during Kharif, 2014 (June to September). The treatments included in the investigation were maize alone (T₁), maize + redgram under additive row system (T₂), maize + greengram under additive row system (T₃), maize + sunflower under additive row system (T₄), maize + sesame under additive row system (T₅), maize + castor under additive row system (T₆), maize + redgram under paired row system (T₇), maize + greengram under paired row system (T₈), maize + sunflower under paired row system (T₉), maize + sesame under paired row system (T₁₀) and maize + castor under paired row system (_T11). The present study clearly revealed that higher growth parameters (plant height, LAI and DMP) of maize were noticed under intercropping of greengram with maize under paired row system (T₈). Intercropping system favorably influenced the yield of maize and the highest maize grain yield of 6048 kg ha<strong>^-</strong>¹ was recorded with maize + greengram paired row system (T₈) and it was on par with maize + greengram in additive row system (T3) and maize alone (T1).
