abstract
A field experiment was conducted to study the response of maize (Zea mays L.) to nano urea under Scarce Rainfall Zone of Andhra Pradesh on sandy loam soils at College Farm, Agricultural College, Mahanandi campus of Acharya N. G. Ranga Agricultural University during rabi, 2023-2024. The experiment was laid out in randomized block design with nine nitrogen management practices and replicated thrice. The results revealed that, application of 100% RDN (33% basal + 33% knee high stage + 33% tasseling stage) + two foliar sprays of nano urea at knee high stage and tasseling stage (T₄) recorded highest plant height, number of leaves plant^-1, lesser number of days to attain days to 50% tasseling and silking, highest grain and stover yield of maize. The soil application of conventional urea along with foliar application of nano urea improved the growth and yield in maize under scarce rainfall zone of Andhra Pradesh.
