摘要：

A study was carried out during 1992 and 1993 to find out effect of cutting management and nitrogen levels on fodder production of paragrass [Brachiaria mutica (Forskaal) Staptf]. The highest green-forage and dry-matter yields of 359.0 and 101.20 q/ha respectively were recorded when the crop was cut at 60-day intervals and fertil ized with 60 kg N/ha. This treatment also gave the highest-gross return (Rs 17 950/ ha), net return (Rs 12,489/ha), net return/rupee invested (Rs 4.67/Re), gross energy but put (182,160 MJ/ha) and net energy out put (178,719 MJ/ha). However, the highest energy-use efficiency (152.23) and energy productivity (6,743 g MJ/ha) were Obtained where no N was applied and the crop was cut at an:interval of 75 days.
