Abstract: India is second largest (103.5 m t) producer after china (145.7 mt) (USDA, 2016). Delay in the release of canal water for irrigation due to late onset of monsoon is a common phenomena Northern Telangana agroclimatic zone of Telangana state. Agronomic practices such as transplanting age, plant spacing, and fertilizer frequencing in irrigated paddy production can have a significant impact towards the performance in rice growth and yield. A study was conducted during kharif season of 2013 and 2014 to investigate the optimum transplanting age, spacing and fertilizer frequency for extra early rice variety Pradhyumna (JGL-17004), under late season condition. The study treatments adopted were three main treatments representing age of transplanting viz., 15,20 and 30 days old seedlings, sub plots three spacing viz., 15X15, 15X10 and 10X10 cm and in sub - sub plots two fertilizer frequencies viz., and two slits – basal and panicle initiation or three splits - basal-maximum tillering and panicle initiation, replicated 4 times each. Results of the experiment depicted that transplanting seedlings at the age of 20 days at a spacing of 15 X10 or 10X10 cm and split application of fertilizer either in 2 splits (basal and panicle initiation) or 3 splits (basal, maximum tillering and panicle initiation) is most suitable for obtaining optimum grain yield in extra early rice variety (JGL – 17004) under late season condition at Northern Telangana Agro climatic zone of Telangana state, India.
