Six advanced sorghum (Sorghum bicolor L. Moench) hybrid crosses, viz.2295A x CB3’, 456A x CB134, 3060A x B144, 3060A x CB50, 415A x CB33, 3060A x CB141 along with two popularhy brids CSH16 and Mahalaxmi 296 were evaluated in rice-fallows under zero tillage during 2011–12 and 2012–13 at farmer's field in Guntur district of Andhra Pradesh. Grain yields of 456A x CB134 (9.05 t ha−1) and CSH 16 (8.62 t ha−1) were significantly higher than Mahalaxmi 296 (5.88 t ha−1). The increase in grain yield was mainly due to maximum panicle weight, 100-grain weight, panicles m−2, grain weight panicle−1 and grains panicle−1. The lowest grain yield (6.06 t ha−1 and 5.43 t ha−1) during both the years was recorded with Mahalaxmi 296, followed by 3060A x B144 (6.46 t ha−1) and 3060A x CB141 (5.99 t ha−1). The plant height had positive correlation with stover yields.
