Seven sorghum hybrids (Mahalaxmi 296, NSH 27, SBSH 151, Kaveri 6363, CSH 23, CSH 16 and CSH 15R were evaluated for their relative response to 5 levels of nitrogen (25, 75, 125, 175 and 225 kg/ha) in rice-fallows under zero tillage during rabi 2009-10 at farmer's field in Guntur district of coastal Andhra Pradesh. Significantly highest grain yield (8.04 tonnes/ha), nutrient uptake and benefits were recorded with 225 kg N/ha. Among different hybrids, SBSH 151, CSH 16, Kaveri 6363, NSH 27 and Mahalaxmi 296 being on a par with each other produced significantly higher grain yields (7.09-7.27 tonnes/ha). The lowest grain yield (5.67 tonnes/ ha) was recorded with CSH 15R followed by CSH 23 (5.88 tonnes/ha). Higher protein content in sorghum grains (10.0- 10.06%) was recorded by CSH 15R and CSH 16 due to higher nitrogen concentration (1.6-1.61%). Source
