Machine transplanted rice (MTR) is an emerging production system in South India to address the labour shortage. No research has been done in this aspect on optimizing nitrogen management to produce high yield. In this study, influence of varying nitrogen rates and time of application were studied with respect to grain yield, its components and economic returns. Nitrogen was applied in two, three and four splits, besides a basal dose at the rates of 120, 160 and 200 Kg/ha. The MTR did not respond to increasing N level from 120 to 200kg/ha, though the yield levels improved substantially (11.35%) Application of nitrogen in four splits (Initial tillering (IT), tillering (T), Active tillering AT) and Panicle initiation (PI) and three splits (IT, AT and PI) significantly enhanced the grain and straw yields with better net returns over two splits (AT and PI) indicating the importance of a different fertilizer schedule for MTR over transplanted rice.
