A field experiment was conducted from kharif 2009 to kharif 2011 on different sites at the research farm of Maize Research station, Khedbrahma, S. D. Agricultural University, Sardarkrushinagar (North Gujarat) under arid and semiarid agro climatic zone (AES-1). The different treatments viz., T1 : maize + pigeon pea 1:1, T2 : maize + black gram 1:1, T3 : maize + green gram 1:1, T4 : maize + castor 1:1, T5 : maize + sesamum 1:1, T6 : maize sole 45 cm., T7 : pigeon pea sole 90 cm., T8 : black gram sole 45 cm., T9 : green gram Sole 45 cm., T10 : sesamum sole 45 cm., T11 : castor sole 90 x 60 cm., T12 : castor as relay crop in maize were tried out in maize based intercropping system. The results were revealed that during all the three years as well as pooled different inter cropping treatments was found significant in terms of maize equivalent yield (MEY). During the first year, maize + sesamum (2887 kg ha-1) gave significantly the highest MEY but it was at par with T2, T3, T4, T7, T10, T11 and T12 treatments. During the second year, green gram sole gave the significantly highest MEY (3684 kg ha-1) but it was at par with T4 and T11 treatments. During the third year, maize + castor (1:1) gave significantly higher MEY (4465 kg ha-1). On the basis of three years pooled data, maize + castor (1:1) gave significantly higher MEY (3508 kg ha-1) but it was at par with castor sole 90 x 60 cm which was 70.62 % higher yield than sole maize. Looking to the economics of different intercropping systems, maize + castor (1:1) recorded higher gross return (` 47709 /ha), net return (` 36509 /ha) and LER (1.25) whereas BCR value was higher with castor sole at 90 x 60 cm sowing (5.38).
